Vitamin E and organic selenium for broilers from 22 to 42 days old: performance and carcass traits
ABSTRACT This study was conducted to evaluate the effect of vitamin E and selenium on performance, viability, productive efficiency, and yields of carcass, major cuts, and organs of broilers from 22 to 42 days submitted to cyclic-heat stress. The experimental design was randomized blocks, in a 2 × 3...

| description | ABSTRACT This study was conducted to evaluate the effect of vitamin E and selenium on performance, viability, productive efficiency, and yields of carcass, major cuts, and organs of broilers from 22 to 42 days submitted to cyclic-heat stress. The experimental design was randomized blocks, in a 2 × 3 factorial arrangement with two levels of selenium (0.1 and 0.3 mg/kg) and three levels of vitamin E (300, 400, and 500 mg/kg), plus a control treatment. Animals were submitted to a natural condition of high cyclic temperature. Organic selenium levels of 0.1 and 0.3 mg/kg associated with 300, 400, and 500 mg/kg of vitamin E were tested. The level of vitamin E did not affect the performance or production efficiency of broilers in the period from 22 to 33 days and 22 to 42 days. However, the selenium inclusion level of 0.3 mg/kg improved the viability in both phases. The yields of carcass, major cuts, intestine, and heart were not influenced by the levels of selenium and vitamin E, whereas abdominal fat for the selenium level 0.1 mg/kg decreased linearly with the inclusion in vitamin E. |
