| Abstract: | To study the effects of dietary crude protein(CP) levels on laying performance and egg quality of Beijing YouJi during different laying periods in free range system.Six hundred 19-week-old Beijing YouJi with no significant body weight difference were chosen and randomly allocated to 6 groups(groups 1 to 6),100 birds per group,fed with corn-soybean meal based diet,and raised in specially established free range houses.Groups 1,2 and 3 were for the trial during early period of laying(19 to 21 weeks),groups 4,5... |
