Castor bean hulls (CBH), co-products of castor oil extraction, are high in dry matter (DM) and fiber and are emerging as alternative roughage in sheep feed. This could reduce feed costs since other sources of roughage can be more expensive. The effects of replacing Tifton 85 hay with CBH at 0, 33, 66 and 100% in the diet of sheep on the carcass characteristics, weights and yields of retail cuts and carcass meas...
This study estimated the genetic diversity and structure of 12 genetic groups (GG) of locally adapted and specialized pigs in the state of Pernambuco using 22 microsatellite markers. Nine locally adapted breeds (Baé, Caruncho, Canastra, Canastrão, Mamelado, Moura, Nilo, Piau and UDB (Undefined Breed)) and 3 specialized breeds (Duroc, Landrace and Large White), totaling 190 animals, were analyzed. The Analysis o...
O trabalho teve como objetivos determinar a composição química e energética do farelo de algodão produzido pela BUNGE Alimentos S/A, marca registrada como Farelo de algodão de alta energia (FAAE®) e avaliar a inclusão deste no desempenho de frangos de corte. Determinou-se a composição química, aminoacídica e energética (utilizando-se o método de coleta total de excretas, com duas coletas ao dia). Foi utilizado ...
This research aimed at generating and evaluating prediction equations to estimate metabolizable energy values in poultry offal meal. The used information refers to values of apparent and true metabolizable energy corrected for nitrogen balance (AMEn and TMEn) and for chemical composition of poultry offal meal. The literature review only included published papers on poultry offal meal developed in Brazil, and th...
Foi realizado um experimento para avaliar os efeitos da inclusão de farelo de girassol em rações para frangos de corte sobre o desempenho, o rendimento de carcaça e dos cortes e a viabilidade econômica. O delineamento experimental foi em blocos casualizados com cinco níveis de farelo de girassol (0, 5, 10, 15 e 20% da dieta basal), oito repetições e 20 aves por unidade experimental. As aves e as rações foram pe...
The objective of this study was to evaluate the effect of including guava wastes in the feed on the performance and carcass yield of broiler chickens. An experiment was carried out with 300 male Cobb strain chicks, in a randomized complete design with five levels of waste and five replications. A reference diet based on corn and soybean meal and four feeds with 3, 6, 9 or 12% guava waste were evaluated. The fee...
