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 Relatório de Estágio Supervisionado Obrigatório(2019-12-12) Silva, Raíssa Camila da; Ribeiro, Maria Norma; http://lattes.cnpq.br/3643578234373660; http://lattes.cnpq.br/4420581591960235Item 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 Relatório de Estágio Supervisionado Obrigatório(2019-07-08) Corrêa, Agni Martins Nunes; Soares, Luciana Felizardo Pereira; http://lattes.cnpq.br/4071178363761831; http://lattes.cnpq.br/9829552791035551Item 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.
