Desempenho de bovinos jovens alimentados com dietas contendo grão úmido de milho ou sorgo

Abstract

The differences on performance of young cattle fed diets with high moisture corn or sorghum were evaluated in two treatments, where the main energy source of the total diet was composed of high moisture corn (HMC) or sorghum (HMS). Ninety Angus x Nelore crossbred young bulls, averaging 8 month of age and 240 kg BW and fed during 172 days were allotted to two experimental treatments as a completely randomized design. No treatment effect on average daily gain, total weight gain and slaughter final weight was observed. Regarding the carcass, ribeye area, subcutaneous fat thickness and rump fat thickness also did not differ between treatments. In conclusion, the totally replacement of high moisture corn by high moisture sorghum did not affect performance of feedlot young cattle. © 2008 Sociedade Brasileira de Zootecnia.
