摘要: An experiment on 55 Lohman Brown hens examined the effect of different dietary levels maize- and rye distillers dried grains with solubles (mDDGS rDDGS, respectively) nutrient digestibility, content metabolizable energy in diet balance nitrogen, calcium, phosphorus, zinc. Experimental diets were isocaloric isonitrogenous contained 0, 5, 10, 15, or 20% mDDGS rDDGS. Diets rDDGS also supplemented NSPhydrolysing enzymes. It was found that 10 15% a had no apparent digestibility nutrients, content, N, Ca Zn; decreased crude fat lowered level diet, whereas 15 negatively affected organic matter level. A inclusion had, however, positive phosphorus balance. Addition feed enzymes increased utilization containing DDGS.
