Item Fontes lipídicas na gestão estratégica de redução de custos com alimentação de cabras leiteiras(2023-09-15) Araújo, Ayrton Manuel Silva de; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/4482266576342953Animal feed is crucial for dairy production and represents a significant part of production costs. The objective was to evaluate lipid sources, as a strategy to reduce feed costs, whether or not associated with Spineless cactus in goat milk production. For the study, 12 lactating Saanen goats were used, with an average body weight of 55 ± 8 kg, distributed in a 4x4 Latin square, with a 2x2 factorial arrangement. The treatments consisted of two lipid sources, Coconut fruit pulp by-product (PC) and whole cottonseed (CA), associated or not with Orelha de Elefante Mexicana (POEM), in the following proportions: PC - 5% Coconut fruit pulp by-product; PC+POEM - 5% Coconut fruit pulp by-product + 25% POEM; CA – 20% whole cottonseed; CA+POEMA - 20% whole cottonseed + 25% POEMA. Animals that consumed diets that had whole cottonseed as the main source of energy showed higher performance indices (P<0.05). The PC+POEM treatment presented the lowest cost for 1 kg of dry matter (R$ 1.78). The PC diet demonstrated lower daily food costs (R$ 2.54). Total income was higher for the CA + POEM diet (R$ 8.17), as was net income (R$ 4.19). Therefore, it is recommended to combine whole cottonseed with forage palm Orelha de Elefante Mexicana, in the feeding of lactating goats, due to the reduction in feed costs, especially in roughage and better performance, contributing to greater profitability of the activity.Item Fontes de lipídeos associados à palma forrageira sobre as características sensoriais da carne ovina(2022-10-07) Nascimento, Thaís Fernanda do; Guim, Adriana; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/5238680527935892The search for food that meets commercial and healthier requirements has created a greater search for meat of higher quality and nutritional value. In this paper, the goal was to evaluate the effect of diets with different lipid sources associated with forage palm on the sensory characteristics of sheep meat. The research included 39 male animals, without a defined racial pattern, castrated, 4 months old and an average initial weight of 22 kg. The experiment took place in the Department of Animal Science, sheep and goat farming sector of the Universidade Federal Rural de Pernambuco, located in Recife, Pernambuco. The treatments consisted of Tifton Hay and Forage Palm as forage, and ground corn, wheat bran and mineral salt as concentrate. In the experimental diet, cottonseed, corn germ and coconut cake were inserted in the concentrated feed. The animals were housed in individual suspended stalls, containing feeders and drinkers, distributed in a covered shed. The experiment lasted 60 days, with the first 30 days aimed at adapting the animals to diets, facilities and management. The last 30 days were devoted to data collection and evaluations. From the Longissimus lumborum muscle, the characteristics, sensory attributes and commercial value of sheep meat were evaluated. The diets utilized with lipid sources did not show significant differences in the sensory characteristics of sheep meat (P>0.05), showing a positive positioning of the evaluators regarding purchase intention, which makes it a good alternative for lambs in the termination phase.Item Parâmetros fisiológicos e consumo voluntário de ovinos alimentados com fontes de lipídios associados à palma forrageira(2022-05-31) Medeiros, Rodrigo Barbosa de; Guim, Adriana; http://lattes.cnpq.br/5179137865818915; http://lattes.cnpq.br/1454346400034264The objective was to evaluate the effect of different sources of lipids associated with forage cactus in the diet of sheep on the thermal comfort of the animals through physiological indicators and dry matter consumption. The maximum and minimum temperatures, relative air humidity, ambient air temperature of the experimental shed were monitored, whose data were used to calculate the temperature-humidity index (THI) and the Black Globe-Humidity Index (BGHI) aiming at estimate the thermal comfort of animals. The experiment was carried out at the Departamento de Zootecnia (DZ) of the Universidade Federal Rural de Pernambuco (UFRPE), located in Recife-PE. Twenty-four male lambs were used, with a mean age of six months and mean initial body weight of 22.0 ± 1.11 kg. The experimental period was 8 weeks, with isonitrogenous diets, based on forage cactus, tifton hay, maize corn, soybean meal, mineral mixture, with 3 treatments, T1 being composed of cottonseed, T2 of extra fat corn germ and T3 of dry coconut film. In order to evaluate the physiological parameters, respiratory frequency (RF), heart rate (HR), rectal temperature (RT) and body temperature (BT) were measured, the latter being measured at 4 points on the animal's body, forehead, neck, loin and shin. Data were collected every 2 experimental weeks at 8:00 am and 3:00 pm. The temperature and relative humidity of the air were measured throughout the experiment. The design used was a completely randomized design in a split-plot scheme, allocating the effect of the treatment (diets containing different varieties of lipids) in the plots and in the sub-plots the effect of the evaluation shift (morning and afternoon). The obtained data were submitted to analysis of variance and average grade comparison by Tukey test and Pearson correlation analysis between variables. There was no significant interaction between the factors (diet and shift), and there was no dietary effect on the respiratory frequency and body temperature variables, however, the heart rate and rectal temperature variables showed a difference (p ≤ 0.05) on the shift, being higher in the afternoon. Despite being susceptible to heat stress according to the high THI and BGHI, thanks to the adaptability and metabolic strategies of sheep to dissipate heat, the animals were able to maintain body temperature within the normal range for ruminants. 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.
