abstract
This study evaluated the effect of including low-fat dried distillers grains (DDG) on young Nellore bulls performance, nutritional parameters, and nitrogen metabolism. Thirty-five Nellore cattle were randomly divided into four diets: without dried distillers grains (D0) or with the inclusion of DDG at 150g/kg (D150), 300g/kg (D300), or 450g/kg (D450). The evaluation period lasted 126days, and three periods of collection of feces and urine were carried out. Final body weight (P=0.099) and average daily gain (P=0.097) tended to decrease linearly; the digestibility of dry matter (P<0.001), organic matter (P<0.001), ether extract (P<0.001) and nonfiber carbohydrates (P<0.001), and intakes of total digestible nutrients (TDN, P<0.001) decreased linearly. The increase in crude protein intake (P<0.001) did not result in an increase in the amount of nitrogen retained (P=0.540). We concluded that the inclusion of low-fat DDG in finishing diets up to the level of 450g/kg tends to reduce animal performance and the intake of TDN.
