Item Influência do sexo e número de crias por parto no ganho de peso de cabritos leiteiros(2018-06-29) Rodrigues, Edgleston Silas Ferreira; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/4943460628945352The objective of this study was to evaluate the influence of sex and number of kids per birth on the weight gain of dairy goats. The study was carried out in the goat sector, at the Department of Animal Science, at the Universidade Federal Rural de Pernambuco. A total of 45 kids were born, 18 males and 27 females, from 27 Saanen females. The number of kids (two and three) per birth was considered. On the second day of life, the animals were separated from the mothers and introduced into the artificial feeding system. The animals were weighed at birth, on the 10th, 45th and 60th days, on a digital scale. Analyzes of variance and the comparison of means by the Tukey test at 5%. Influence (P <0.05) of the number of kids per birth on birth weight, weight at 10, 45 and 60 days of life, mean weight gain and total weight gain of the animals were verified. There was an effect (P <0.05) of brood sex on birth weight and weight at 10, 45 and 60 days. It is concluded that the number of animals born per birth and sex influence the birth weight and the weight gain of the animals up to 60 days in Saanen animals submitted to artificial feeding.Item Análise do comportamento de compra de rações dos proprietários de cães da Zona Norte do Recife-PE(2018-08-15) Ribeiro, Lucas Sales; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/5997449933103860The Pet Food segment is what most represents the pet market in Brazil, providing consumers with a wide variety of brands and types of feed. The objective of this research was to identify which aspects are important in the choice of ration and to analyze the capacity of interpretation of the labels of these products. Sixty people were interviewed, all of them aged 18 years old and owning at least 1 (one) dog. The data obtained through the application of semi-structured questionnaires were tabulated and analyzed in a descriptive way by frequency using the Microsoft Office Excel® 2013 software. It was concluded that, regardless of the socioeconomic profile of the interviewees from the Northern Zone of Recife, all presented the habit to buy rations with the aim of offering the best food for your dog. However, there is a lack of technical knowledge on the part of animal nutrition and difficulties in interpreting important information to achieve this goal.Item Parâmetros reprodutivos do rebanho caprino da raça Saanen criados no Departamento de Zootecnia /UFRPE-SEDE(2018-08-15) Pimentel, Rebeca de Souza; Souza, Andreia Fernandes de; http://lattes.cnpq.br/6354486109796073; http://lattes.cnpq.br/5869187631835116The objective of this study was to analyze the reproductive parameters of the goat herd of the Saanen breed raised in the Department of Animal Science / UFRPE-SEDE, in relation to the reproductive and productive efficiency of the short protocol of induction of estrus, strategically used in order to increase the production potential of the animals throughout their reproductive life. From the semiological evaluation, 34 females were classified according to body condition score (ECC) and submitted to the intensive regimen with diet based on 200 g concentrate / day, in addition to tifton hay, water and mineral salt ad libitum. Females were induced to estrus using short protocol of estrus induction / synchronization, for which a CIDR containing 0.33 g of progesterone and 0.3 mL of Cloprostenol Sodium (CIOSIN) was introduced into the female vagina on day zero (D0) The device remained in the cranial portion of the vagina for five days (D5), was given intramuscularly. and 200uI of equine chorionic gonadotrophin (eCG; Novormon 5000) was administered intramuscularly. The detection of estrus was performed through the ruffling and the covers through controlled mount. The diagnosis of gestation was performed 30 days after the coverage. Regarding estrus observation, 97.06% (33/34) of the females went into estrus. Regarding the estrus observation time (24 to 72 hours after implant removal), 64.70% (22/34), 17.64% (6/34), 14.70% (5.34) females presented estrus in 24, 36 and 48 hours, respectively. Regarding the rate of conception, 25 of them engaged, with a percentage of 73.53% conception. In relation to the birth rate it was 96%, with the total of 49 kids born. The mean birth weight of the offspring (two animals / parturition), mean weight 3.4 kg, already (three animals / parturition) presented a mean weight of 2.7 kg. The mean weight at 45 days,10.2 kg (two animals / childbirth), already (three animals / childbirth) had an average weight equal to 8.3 kg. On the other hand, the prolificacy rate for male exposed goat, which relates the number of goats born per female / year, showed an average of 1.44 goats / female / year, with reproductive efficiency of 117,65% or 1, 17. The use of short induction protocols associated with herd management tools, among them the body condition score, weighing and zootechnical control were fundamental for the development of the herd.Item Produção de leite e custos da alimentação de cabras Saanen em lactação recebendo dietas contendo palma orelha de elefante mexicana em substituição à palma miúda(2018-08-21) Corrêa, Agni Martins Nunes; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/9829552791035551The objective was to evaluate milk production and cost of feeding Saanen goats in lactation receiving diets containing palm ear of Mexican elephant in replacement of the small palm. The experiment was carried out in the Caprine Sector of the Department of Animal Science at the Federal Rural University of Pernambuco. Ten adult Saanen goats were used in lactation, with a mean body weight of 50 kg and a mean milk yield of 3.8 kg of milk per day. The animals were distributed in a double –square Latin experimental design (5x5) according to the lactation period. The diets were distributed according to the following levels of Nopalea cochenillifera replacement by the Opuntia strica: Control; 0%; 11.5%; 23.5% and 35%. Dry matter intake, milk production (3.21 kg) and milk production corrected to 3.5% fat (2.76 kg) did not differ (P>0.05) with the levels of substitution Opuntia strica.The Opuntia strica replacement diet (35%) had the lowest value (2.65 R $ / day) for the daily feed cost. Replacement is recommended of the Nopalea cochenillifera by the Opuntia strica in the diet of lactating goats, since there was no compromise in the consumption and the milk production and for reducing the costs of the diets, generating higher income for the producer.Item Inclusão da cana-de-açúcar (Saccharum officinarum, L.) em substituição à palma forrageira (Nopalea cochenillifera Salm – Dyck) na dieta de ovinos(2018-08-21) Oliveira, Laura Silva de; Conceição, Maria Gabriela da; http://lattes.cnpq.br/2620793027161237The effects of inclusion of sugarcane in substitution of forage palm (0; 25; 50; 75 and 100%) in sheep diets, on intake and digestibility of nutrients and ingestive behavior were evaluated. Five sheep with no defined racial pattern, with initial body weight and 58.0 ± 6.65 kg, with cannulae in the rumen, were distributed in a 5 x 5 Latin square. Stool collection was performed during three consecutive days to determine the digestibility of DM and nutrients. There was a quadratic effect for dry matter intake (DM) (33.73% - 1,101 kg) and OM (39.38% - 1.010 kg). The PB consumption decreased and there was no effect for the consumption of FDN and MOD. The digestibility of MS decreased linearly (P <0.05), while for the digestibility of MO and PB, there was an increase with the inclusion of sugarcane levels in substitution for forage palm. There was no effect (P> 0.05) for feeding times, while for rumination, a quadratic effect was observed with a maximum of 87.27% of substitution (507.4 min / d -1) and the time spent with activity was reduced (P> 0.05). In order to maximize MS intake, it is recommended to substitute sugar cane palm in 33.73% in diets for sheep.Item Concentração de minerais na palma forrageira e suas implicações no metabolismo de ruminantes: revisão de literatura(2018-08-22) Silva, Marisol Ramos da; Guim, Adriana; Silva, Tomás Guilherme Pereira da; http://lattes.cnpq.br/3632014794052859; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/1463080663779484The forage palm is used in the feeding of ruminant animals, mainly in the regions that have low rainfall indexes, because it presents great adaptability to more arid climates and presents great amount of water in its composition, contributing significantly to the watering of the animals. However, this forage has other characteristics such as imbalance of minerals (Ca: P, for example), high concentrations of calcium (Ca), potassium (K) and magnesium (Mg) and low concentrations of phosphorus (P) and sodium (Na) that signal the need for care in the mineralization of the herd. These imbalances can lead to problems in productive performance, reproductive health and health of ruminant animals that consume this fodder resource. Given the importance of knowledge of the mineral composition of foods to formulate suitable diets for ruminant animals the objective was to carry out a bibliographical survey on the role of minerals in ruminant feeding and the concentration of these in the forage palm.Item Histomorfometria do epitélio omasal de ovinos alimentados com dietas baseadas em palma forrageira(2018-08-22) Castro, Amanda Lucy Ferraz de; Guim, Adriana; Silva, Tomás Guilherme Pereira da; http://lattes.cnpq.br/3632014794052859; http://lattes.cnpq.br/5179137865818915The objective of this study was to evaluate the effect of diets based on forage palm on histomorphometric and histopathological parameters of omasum epithelium and ovine abomasum submitted to forage palm diets. Thirty-two lambs with no defined racial pattern were used, male, uncastrated, with a mean age of six months and initial body weight of 21 ± 2.06 kg, housed in individual stalls equipped with feeder and drinking fountain. The animals were distributed in a completely randomized design with four treatments and eight replicates. The experimental period was 73 days and the experimental treatments consisted of a base diet (elephant grass hay, maize corn meal, soybean meal, urea and mineral salt) and three other diets in which elephant grass hay was replaced in 68% by genotypes of forage palm (small, IPA-Sertânia or Mexican elephant ear), all formulated to allow weight gain of 200 g day-1. After 73 days of confinement, the animals were weighed and slaughtered following the norms in force in the country. The weights of the stomachs and their respective contents were quantified, as well as tissue samples of the omasum and abomasum were collected for histological analysis. Up to the present moment, it can be stated that the diets based on forage palm provided greater stomach weight, with lower content.Item Comportamento ingestivo de caprinos e ovinos recebendo diferentes fontes de carboidratos associado à ureia em substituição ao farelo de soja(2018-08-22) Silva, Rita de Cássia Manso; Guim, Adriana; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/0329511011280265Northeastern Brazil has a great ability to raise goats and sheep in the semiarid region, but there is a difficulty in homogeneous production of food during the year. The use of alternative food in feed that is adapted to the semi-arid climate, such as forage palm and manioc, can minimize the problem. The objective of this study was to analyze the effect of different sources of carbohydrates associated with urea in replacement of soybean meal on the ingestive behavior of sheep and goats. Four goats and four sheep with permanent fistula in the rumen were used, arranged in a 4x4 Latin square design, receiving the experimental diets with different sources of carbohydrates and urea replacing the soybean meal. The diets were composed of four treatments: a) corn and soybean meal, b) corn and urea, c) manioc and urea scrap, and d) forage palm and urea. Data were analyzed by analysis of variance and the means were compared by the Tukey test, at 5% significance. There was no significant difference (P> 0.05) in the ingestive behavior between goats and sheep. However, animals fed the diet containing manioc and urea showed a longer time in leisure (977.50 minutes / day), followed by the animals of the diets with forage palm and urea (845 minutes / day) corn + soybean meal (822.50) and corn + urea (821.25 minutes). The feeding and rumination efficiencies were not influenced by the animal species either by the diets. Thus, it is concluded that the association of energetic foods produced in the region (palm and manioc rasa) associated with urea does not compromise the ingestive behavior of goats and sheep.Item Análise histomorfométrica do epitélio ruminal de caprinos alimentados com palma forrageira(2018-08-23) Nascimento, Andreza Guedes de Oliveira; Batista, Ângela Maria Vieira; Silva, Tomás Guilherme Pereira da; http://lattes.cnpq.br/3632014794052859; http://lattes.cnpq.br/1209459577975499; http://lattes.cnpq.br/1231614424586412The objective of this study was to measure histomorphometric variables of the ruminal epithelium of goats fed forage palm (total epithelium thickness, keratin layer thickness and thickness of non-keratinized layers) fed with forage palm genotypes: small (Nopalea cochenillifera Salm Dyck) and ear of Mexican elephant (Opuntia stricta Haw), originating from the municipalities of Pernambuco, Lagoa de Itaenga and Ibimirim, in that order, being transported to Recife every 15 days. For each new lot of forage palm, samples were collected with the purpose of quantifying the dry matter and crude protein contents for adjustment of rations. Tifton-85 grass hay, maize corn meal, soybean meal and micro ingredients were commercially available, 36 male SPRD male goats with an average age of 1 year and mean body weight (ICP) of 19.0 ± 2.8 kg were used in a completely randomized design with three treatments and twelve replicates. The animals were individually housed in slatted wooden slats with 1.8 m x 1.0 m (1.8 m2) dimensions, provided with a feeder and drinking fountain, arranged in masonry sheaths covered with asbestos cement tiles. The experiment lasted 100 days, with 30 days for adaptation of animals to experimental conditions and 70 days for data collection. The animals that received the control diet had a greater thickness of the keratinized layer and the non-keratinized layers of the ruminal epithelium (dorsal sacks) in comparison to those that received the diet containing the small palm, without significantly differing from the Mexican palm ear treatment, control diets and with Mexican elephant ear palms cause greater thickening of the keratin layers and non-keratinized layers of the epithelium of the dorsal bags of the rumen of goats, however they can be used to feed goats as they are a good source of nutrients.Item Avaliação do comportamento social de cães que frequentam o “ParCão” do Parque Dona Lindu na Zona Sul do Recife-PE(2018-08-23) Lira, Patricia Monteiro de; Nascimento, Júlio Cézar dos Santos; Fonseca Filho, Lucilo Bioni da; http://lattes.cnpq.br/5884365993751599; http://lattes.cnpq.br/4343017315156292Since its domestication, the dogs have conquered increasingly space in society. These animals contribute directly at quality of life of its owner, either performing duties of humanitarian character or as pet animal. This proximity of man with the dog must, in your majority, to the growth of cities and development of modern civilization, what has decreased the physical space in between these species and isolated the human beings each other. As a result, these animals became considered members of the family, causing a new social configuration in the relationship between both. However, an inappropriate interaction between humans and dogs can trigger a series of disturbances behavioral, such as aggression and separation anxiety. That way, the objective was to of a survey in the “ParCão” located in the park Dona Lindu, situated in the Boa Viagem, South Zone of Recife, at where in this ocasion interviews were made with dog owners to characterize the behavior of dogs and the relationship of interaction animal man. Were used structured questionnaires, applied at random to 60 dog guardians who attend the "ParCão", containing questions concerning the purpose of creation, frequency of tours and the occurrence of abnormal behaviors. The data were tabulated and analyzed descriptively using the software Microsoft Office Excel® 2016, at where it can be concluded that the regularity of the tours has reduced significantly the degrees of aggression and anxiety in these animals, promoting adequate socialization, and thus improving the welfare of both species.Item Índice de escore corporal em cavalos de trabalho e atletas(2018-08-24) Oliveira, Virgínia Theodora Brito Marques de; Manso, Helena Emília Cavalcanti da Costa Cordeiro; Manso Filho, Hélio Cordeiro; http://lattes.cnpq.br/5631206025493479; http://lattes.cnpq.br/7040279344981888; http://lattes.cnpq.br/1481178969488295The objective of this study was to evaluate the body condition score index in work horses and athletes, in order to know if there is difference in body scores between physical activity categories. Data were collected in the months of May and June of 2018. Fifty animals of both sexes were evaluated in the age group from 3 to 16 years and that they were performing physical activities regularly. Being: 27 working horses (traction); 23 service horses (PMPE cavalry); 41 horsepower; 31 horses of vaquejada; and, 28 racing horses. The evaluation of the corporal score was performed according to the methodology established by Henneke et al. (1983) established 6 areas of palpation and visualization in the body to determine fat deposition and nutritional status on the scale from 1 to 9. The cowherd animals had a higher body score than those of running and work, and a similar result to gait and service. Although the animals begin to deposit fat when they reach adulthood, there was no difference between the age groups <5, between 5 and 10, and> 10 years. The mean body score of the female animals (~ 4.91) was higher than the mean male (~ 4.67). The males were similar in relation to the physical activity, the values were similar for those of vaquejada (with higher value ~ 5,10), gait, running and service, and the lowest score was observed in working males (~ 3.87). When the females with the same parameter were evaluated, the ones with the lowest value were those of running (~ 4.25) with approximate results to the work (~ 4.50), and there was no difference among the cowherd females, which presented higher scores (~ 5.27) and those of service, walking and work. When males and females were evaluated for physical activity, males had a higher score (~ 4.85) than females (~ 4.25), and females (~ 4.50) larger than males (~ 3.87). For all other categories, no differences were observed. ECC evaluation remains a valid method for indicating the nutritional level of the animal. The results show that there is interaction between body condition score and physical activity category performed by horses.Item Qualidade de ovos de galinhas poedeiras alimentadas com dietas contendo minerais complexados a aminoácidos(2018-08-24) Silva, Paulo Sérgio da; Rabello, Carlos Bôa Viagem; Silva Júnior, Rogério Ventura da; http://lattes.cnpq.br/9086218474929748; http://lattes.cnpq.br/4760288746238700; http://lattes.cnpq.br/5300952184603589The objective of this study was to evaluate the effects of micronutrients (Zn), Manganese (Mn), Copper (Cu) and Iron (Fe) in the form of minerals complexed to amino acids (MCAA) associated with inorganic sources of feed for laying hens. The research was developed in the Ovo Novo farm, Caruaru, Pernambuco, and the laboratory analysis carried out in the Animal Science Department of the Federal Rural University of Pernambuco. A total of six hundred and forty Lohmann Brown-Lite llaying hens from 50 to 70 weeks of age were used, of which three hundred and twenty were fed MCAA from the breeding and rearing phase, and three hundred and twenty were not fed diets containing MCAA. The birds were housed in cages and distributed according to a completely randomized design in a 2 x 4 factorial scheme, consisting of 8 treatments with 8 replicates of 10 birds per experimental unit. The treatments consisted of 70, 70 and 8 mg / kg Zn, Mn and inorganic Cu (control) and 40, 40 and 2.75 mg / kg supplements associated with 30, 30 and 5.25 mg / kg Zn, inorganic and organic Mn, respectively (test), delivered from birth up to 30 weeks of age. They had been evaluated: weight of the egg (g), color of the egg yolk, height of albúmen (mm), weight of the eggshell (g), thickness of the eggshell (mm) and Haugh Unit. The data had been submitted to the analysis of variance by means of computational program R Studio® and the means subbmetted tukey test (P<0.05). But the thickness of eggshell was influenced by the treatments. It did not have interaction between the diet growth and the diet production, in this manner, the suplementation during the growing phases had not influenced to the parameters of internal quality of eggs in the production phase. However, it can be verified that the birds supplemented with sources MCAA had presented thickness of eggshell best. The partial substitution of the Zn, inorgânicos Mn, Cu and Fe for MCAA improves the thickness of the eggshell of eggs of the birds.Item Efeito de diferentes alimentos sobre a curva de glicose em equinos sadios(2018-08-24) Trindade, Keity Laiane Gomes; Manso Filho, Hélio Cordeiro; http://lattes.cnpq.br/5631206025493479; http://lattes.cnpq.br/6037518474506684Currently, there is a wide variety of new components used in the formulation of equine diet; however, some foods are still kept, mainly for work animals, by tradition or culture in various regions of the country. This work aimed to evaluate the glycemic curve of five different foods commonly provided for equines. Five adult equines were used, in maintenance, body score 4.5 in a scale of 9, distributed in a factorial with 5 horses and 5 foods (wet corn grain, wet corn grain plus common salt (50g), pelleted alfalfa, extruded corn, extruded rice), and with an interval of 4 days between each test. On the test day, they were isocalorically supplemented (3.0 Mcal/animal) and blood samples were obtained after 12h of fasting and post-feeding in the following periods: +30, +60, +90, +120, +180, +240 minutes. The samples were used for determination of glucose and total plasma proteins (TPP). The results were submitted to ANOVA and Tukey's test. The results indicated differences between the treatments (p <0.05) and between the blood collection phases (p <0.05), but without significant interaction for glucose and for TPP. The highest increase in TPP was alfalfa (8.10 mg/dL) and wet corn with salt (7.90 mg/dL), both with a peak at + 30 min, but without differences between them (p> 0.05). The highest glucose variation occurred with extruded corn, with a peak at + 120 min (145 mg/dL). Evaluating the phases, regardless of the treatments, it was observed that the TPP peak occurred at + 30 min (~7.65 mg/dL) and for glucose was + 120 min (~ 131.3 mg/dL). Thus, it is possible to assert that both alfalfa and corn with salt apparently promote a large displacement of liquids to the intestines by raising TPP and extruded corn is the most glycemic food. It is concluded that different foods produce different glycemic curves, with the pelleted alfalfa producing the smallest curve and the extruded corn producing the largest. Therefore, all food must be properly studied and tested for its metabolic function in order to use it in the most appropriate way and that contributes to the animals’ health.Item Qualidade da carne de frangos de corte alimentados com gérmen integral de milho(2018-08-24) Oliveira, Daniela Pinheiro de; Rabello, Carlos Bôa Viagem; http://lattes.cnpq.br/4760288746238700; http://lattes.cnpq.br/5736746816339448The objective of this study was to evaluate the quality of breast, thigh and overcoat meat of broilers fed diets containing different levels of inclusion of WCG. A total of 648 one day old Cobb500 broilers were used, which were distributed in a completely randomized design with six treatments and six replicates, with 18 birds per experimental unit. The treatments consisted of a reference diet and five diets tests with inclusion of 4, 8, 12, 16 and 20% of WCG, respectively. The broilers were housed in a shed divided into boxes measuring 2x1m and equipped with tubular feeder and nipple drinking fountain. Food and water were supplied ad libitum. After 42 days, two broilers per plot were slaughtered for evaluation of pH, water holding capacity (WHC), shear force, loss through cooking (LTC), peroxide index (PI) and coloration. Data were submitted to MANOVA and multivariate factor analysis with minimum value of load for a variable to be significant of 0.70 within a factor and the method of factor rotation was the varimax raw. The three factors studied - variables pH, WHC and LTC - did not present significant results with the inclusion of WCG. However, factor analysis indicated three main factors, where factor 1 grouped all the variables associated to coloration, showing that there is a positive correlation between the colorations of cuts (chest, thigh and overcoat) and addition of WCG in the diets of the boilers. The factor 2 grouped shear characteristics, showing negative interrelation. It means that an increasing of the WCG in the diets reduced the shear force of the broilers' breast. The factor 3 grouped the characteristic of breast peroxide index, expressing positive interrelation. It means that an addition of higher levels of WCG in the broilers’ diet tends to increase the rate of breast peroxide index. It can be concluded that WCG can use up to 20% in broiler diets without altering meat quality and that WCG showed a strong correlation with shear force, peroxide index and the chick coloration.Item Avaliação do perfil morfométrico de cavalos da raça Quarto de Milha de Vaquejada(2018-08-24) Santos, Vinícius Henrique da Silva; Manso Filho, Hélio Cordeiro; http://lattes.cnpq.br/5631206025493479The Vaquejadais a genuine northeastern equestrian sport, of centenary origin, due to the cattle breeding in the Sertão.In this sport, Quarter Horse stands out for being an animal of temperament docile and extremely fast in races of short distances, comprising about ninety percent of the animals used in a competition.With the increase of the popularity of the Vaquejada, there was a greater search for animals that stood out in the tests, that is, of superior genetics and for that, crossings were thrown, turned only for the genealogy.Biometrics is intended to aid in the breeding programs, definition of racial pattern, identification of defects, as well as the selection of specific abilities that the animal will perform, since equine morphology correlates with function.The objective of this work was to evaluate the biometry of Quarter Horse animals used in the sport of Vaquejada. A total of 45 animals were evaluated. 12 equines of Pull in Training (PTr), 22 equines of Pull in competition (PCom) and 11 equines ofhelper (E). Data were collected from 10 linear measures, in addition to body mass. The data were submitted to analysis of variance (ANOVA) and the means were compared by the Tukey test, with significance level of 5%. SigmaPlot 13.0 was used for windows in all statistical analyzes. Significant measurement (P <0.05) for height of the withers, croup height, body length, croup length, thoracic perimeter, breast width, in addition to the body mass, being the values found superior in the pull animals compared to the helper.The results showed that the Vaquejadahorses have different biometrics because they perform different functions.This information can contribute to guide which function the animal will play in the sport, as well as its training.Item Principais plantas tóxicas em pastagens do Nordeste, com ênfase em Pernambuco(2019) Ferreira, Claudia Maciel; Cunha, Márcio Vieira da; http://lattes.cnpq.br/8936474723708253; http://lattes.cnpq.br/4541443783709386The number of plants described as toxic grows more and more. There are currently approximately 130 plant species considered toxic. The presence of toxic plants in production systems can generate losses and know which plants are, morphological characteristics, toxic principles, toxic dose, toxicity level, animals that are affected, as well as preventive actions, are of utmost importance for livestock. To be considered toxic the plant needs to be tested through laboratory experiments and with the animal species in question, as there are many differences in effects caused by plants between animal species. And plants considered toxic, experimentally need to cause some kind of pathology when ingested by animals and occur in natural conditions, so they are considered toxic plants of livestock interest. Objective of this work was to perform a literature review on the main toxic plants of the Northeast, with those occurring in the state in Pernambuco. Toxic plants affect animals in a number of ways, such as gastrointestinal disturbances, central nervous system problems, reproductive system problems, and photosensitization and sudden death. Toxic plants that occur on pastures can cause many losses, including animal death. Knowing these plants is strategic for proper pasture management. The best way to control the occurrence of these plants is to properly manage pastures, with stocking adjustment based on forage mass and definition of grazing frequency based on pasture growth.Item Cabras Saanen Primíparas e Multíparas: Prolificidade, produção e composição do leite e curva de Lactação(2019) Correia, Laiz de Souza; Carvalho, Francisco Fernando Ramos de; http://lattes.cnpq.br/8552194153767195; http://lattes.cnpq.br/2578689453098156One of the characteristics that determine the efficiency of the production system is prolificity. In addition, factors such as nutrition, persistence of lactation and order of birth can contribute to the quantitative and qualitative characteristics of milk, making the production system more viable. In this sense, the objective was to evaluate the prolificacy, milk yield, milk composition and lactation curve of primiparous and multiparous Saanen goats. Twenty lactating Saanen goats (508,27 kg body weight) were used, divided by calving category, being 8 primiparous and 12 multiparous, with an average production of 3.5 kg of piglet corrected for 3.5% fat. The experimental diet was formulated to meet the nutritional requirements of lactating goats, consisting of forage palm, hay and concentrate in a ratio of 50:50 roughage / concentrate. After delivery, information on calving order, weight and sex of the offspring were collected. The milking was performed twice a day and the individual daily productions were computed. For analysis of the lactation curve as a function of delivery, the model proposed by Wood was used and for analysis of milk yield and composition, a variance analysis was performed using the linear model procedure and comparison of means using the Tukey test. at 5% probability. The prolificacy values found for Saanen goats were 1.67 for primiparous goats and 1.93 for multiparous goats. There was no significant difference (P> 0.05) in the order of delivery for fat, protein, lactose, total solids, non-fat solids contents. However, for milk production there was a significant effect (P <0.05), the multiparous (3.20 kg) presented higher average production when compared to the primiparous (2.60 kg), similarly the Somatic cells (SCC) showed significant effect (P <0.05), where multiparous goats had higher rates. Regarding the results obtained for lactation curves, the estimated lactation peak was 58 days with an average production of 3.14 kg, while according to the observed data the lactation peak occurred at 71 days with an average production 3, 26 kg for primiparous goats. In the multiparous, we observed that the estimated lactation peak was 29 days with an average production of 3.99 kg, while the observed data the peak lactation occurred at 60 days with an average production of 3.94 kg. Primiparous and multiparous Saanen goats presented excellent prolificacy rates, with higher milk yield observed in multiparous, however in the lactation curve the primiparous showed higher productive persistence.Item Análise mercadológica da piscicultura ornamental em Camaragibe(2019-01-01) Costa, Anderson Cristiano Ferreira; Porto Neto, Fernando de Figueiredo; http://lattes.cnpq.br/1475750525654086; http://lattes.cnpq.br/3708648078406018The production of ornamental fish has important issues such as: recreational purpose since aquariums can be placed in different places; social since it generates employment in diverse scales; and economics because it represents annually millions of US dollars around the world, including in the city of Camaragibe that is part of the Metropolitan Region of Recife. In that way, acess how this demand and supply of fishes in this municipality is essential for both sellers and buyers, in order to take decisions about which species to choose. For this reason, the market for ornamental fish in Camaragibe has been studied. A questionnaire was carried out verifying if there is intention to create ornamental fish by the local population, as well as what the characteristics of these fish should be for the purchase to be made or not. At the same time, the supply market of these aquatic organisms was studied through pre-structured questionnaires, where the relevance of an investment in marketing and development of techniques of the sector was perceived.Item Avaliação de época de plantio para estabelecimento de Aveia preta (Avena strigosa Schreb.) durante a estação fria, Norte da Flórida-EUA(2019-01-14) Abreu, Daciele Sousa de; Santos, Mércia Virginia Ferreira dos; http://lattes.cnpq.br/9565465836878202; http://lattes.cnpq.br/9908872159072612In northern Florida, subtropical climate, forage is the main source of food for herds, using forages for the cool-season and warm-season. During the cool-season, higher animal performance occurs when compared to the warm season, because of the higher nutritive value of the forage. The objective of the work is to evaluate two varieties of black oats (Avena strigosa Schreb) in contrast with other cool-season forages typically used in the region, such as cereal rye (Secale cerealeL.), triticale (X Triticosecole Wittmack), annual ryegrass (Lolium multiflorum L.), and oats (Avena sativa L.), in two planting seasons. The experiment was conducted at the North Florida Research and Education Center, located in the city of Marianna - Florida, USA. It was carried out in a randomized block design with subdivided plots and four replications. The treatments included two planting seasons (January and February plot) and seven varieties of temperate forage plants (sub-plot). Two varieties of black oats (Cosaque and SoilSaver) and five other forages typically used in the region (Horizon 201, Legend 567, Trical 342, FL401 and Earlyploid; n = 56) were evaluated. The experiment was repeated in two consecutive years, 2016 and 2017, in nearby experimental areas. The analyzed variables were herbage accumulation rate and survival rate. Rye (FL 401) and white oat (Legend 567) obtained superior results, producing an average of 1946.13 kg DM/ha of herbage accumulation and black oats (SoilSaver and Cosaque) obtained a mean of 1363,065 kg DM/ha in the months of January. In the February planting, the SoilSaver black oat variety obtained 1889.75 kg of DM/ha, followed by the grains Legend 567 and FL 401, with 1671.87 and 1614.37 kg DM / ha, respectively. For the survival rate, the black oat of Cosaque cultivar and the Azevém of Earlyploid cultivar reported a higher rate in the months of January (100 and 87.50%). In February, the two black oat cultivars, together with Tritical and Azevém, had a 100% survival rate. In general, Black Oat, SoilSaver cultivar, when planted in February, reported similar herbage accumulation and survival rate to commonly used grains in North Florida, USA.Item Digestibilidade dos nutrientes em ovinos Santa Inês recebendo dietas com diferentes fontes de carboidratos associadas à ureia(2019-01-15) Silva, Letycia Cristine Fernandes Lira da; Carvalho, Francisco Fernando Ramos de; http://lattes.cnpq.br/8552194153767195; http://lattes.cnpq.br/3420693856221234The objective of this study was to evaluate the digestibility of diets based on different sources of carbohydrates associated with high urea levels, replacing soybean in diets for sheeps. Four diets were tested with Tifton-85 hay (580 g/kg dry matter) as forage and corn+soybean; corn+urea; cassava scraping+urea and cactus pear+urea as concentrated ingredients. The experiment was carried out at the Animal Science Department of UFRPE. 40 male uncastrated sheep were used, distributed in random blocks, with four treatments and ten replications, housed in individual wooden stalls, equipped with feeder and drinking fountain. The duration of the experiment was 76 days, 20 of adaptation and 56 for data collection. The apparent digestibility (AD) assay was performed by the total fecal collection method. During the period of the digestibility test the feces were collected daily to determine the digestibility coefficients of dry matter, organic matter, crude protein, ethereal extract, neutral detergent fiber, total carbohydrates and non-fibrous carbohydrates. The apparent digestibility coefficients (ADC) were obtained by the relationship between the amount of ingested and excreted nutrients. The data were submitted to analysis of variance and the averages were compared by the Tukey test (P <0,05) procedure using the General Linear Models (GLM) of the Statistical Analysis System (SAS) program. The dry matter digestibility coefficients did not vary among the treatments, except for the animals that were fed with cactus pear+urea (59,66). The diet that contained cactus pear in its composition also provided lower digestibility of organic matter (62,92) and total carbohydrates (63,75), compared to corn+urea (69,50; 69,97) or cassava scraping+urea diets (70,47; 71,91). The crude protein digestibility coefficients were similar for the corn+urea, cassava scraping+urea and cactus pear+urea diets (78,54), being higher than the control diet (74,46). The digestibility coefficients of the ethereal extract were similar to each other in treatments corn+soybean and corn+urea (72,21) and similar to each other in the treatments cassava scraping+urea and cactus pear+urea (60,68). The digestibility coefficient of the non-fibrous carbohydrates was higher for the cassava scraping+urea diet (86,26). It is possible the total replacement of soybean by urea in the experimental diets, especially in the diet composed by the association of manioc and urea, which presented better overall response in the variables evaluated in relation to the apparent digestibility.
