Effect of different nitrogen fertilization of oats and barley on their feeding value in diets for broiler ducks


, : Effect of different nitrogen fertilization of oats and barley on their feeding value in diets for broiler ducks. Acta Academiae Agriculturae ac Technicae Olstenensis, Zootechnica ( 37): 97-108

4 groups of 100 Pekin broiler ducks were fed on complete diets containing 25% barley or oats from 1 to 21 days old. From 22 to 56 days old ducks in each group were divided into 2 subgroups (A, B). All A subgroups were fed on complete diets containing 70% barley or 50% oats. Both cereals were harvested from fields fertilized with nitrogen 0, 60, 120 or 150 kg/ha and used in diets for groups 1, 2, 3 and 4, respectively.
