Item Respostas fisiológicas de ovinos alimentados com palma forrageira(2019-06-18) Silva Neto, José Francisco da; Guim, Adriana; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/5375824647061219The aim of study was to evaluate the effect of forage palm based diets on the physiological indicators of sheep, as well as, to analyze the correlation of these parameters with total digestible nutrients consumption. For this, the experimental protocol was approved by CEUA/UFRPE, under the license of 053/2015, using 36 lambs, with an average age of six months and initial body weight of 23.0 ± 3.11 kg, distributed in a design completely randomized, with three treatments and 12 repetitions. The experimental period comprised 86 days, with a base diet (Tifton hay, maize corn, soybean meal, urea, and mineral salt) and diets in which Tifton hay was partially replaced by forage palm (either Nopalea Cochenillifera Salm Dyck or Opuntia stricta Haw). The diets were given twice a day in the form of complete feed. In order to evaluate the physiological parameters, respiratory frequency (RF), heart rate (HR), rectal temperature (RT) and body temperature (BT) were measured. These data were collected on the 50th and 55th experimental days at 8:00 am and 3:00 p.m. Also, the air temperature and air moisture were measured during the experiment. The obtained data were submitted to analysis of variance and average grade comparison by Tukey test and Pearson correlation analysis between variables. No interaction has been noticed between the diet and the shift, nor was there a dietary effect on the evaluated variables. However, RF and BT were higher in the morning in comparison to the afternoon shift. All the values recorded for HR and RF were above normal for the species. It was verified that the variables RF and BT correlated positively and significantly with the intake of total digestible nutrients in the animals that received the control diet in both shifts. It is concluded that the experimental diets did not cause damages to the physiological parameters, and the climatic conditions are responsible for increasing the physiological variables.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 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 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.
