Item A aplicabilidade do sistema compost barn para a produção de leite caprino na Zona da Mata de Pernambuco(2024-09-30) Carvalho, Carlos Fernandes Lopes; Carvalho, Francisco Fernando Ramos de; http://lattes.cnpq.br/8552194153767195; http://lattes.cnpq.br/9499522180217762Dairy goat farming has been a growing activity in many Brazilian states, especially in regions where traditional management faces challenges related to productivity and sustainability. In this context, the compost barn system, used for bovine milk production, appears as a promising alternative to improve production efficiency and animal welfare. This work aims to analyze whether compost barn is also applicable to the production of goat milk in the Zona da Mata of Pernambuco, addressing its benefits and environmental impacts. The research was carried out through a bibliographical review, comparing publications that analyze the productivity, well-being and health of animals in other types of systems. The results indicate that this new system can provide greater well-being, reduce animal exposure to stressors and increase productivity. It is concluded that the well-being provided by the compost barn system can be a tool to make dairy goat farming viable in the Zona da Mata of Pernambuco.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 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.
