RELATIVE EGG YOLK WEIGHT VARIABILITY AS A BASIS FOR ENHANCING OF BROILER BREEDER REPRODUCTION WITH MAINTAINING HIGH GROWTH RATE OF BROILER-CHICKENS

V.I. Fisinin, L.I. Tuchemskii, A.V. Salamatin, I.V. Zhuravlev, A.M. Dolgorukova

The results of investigations were summarized and analyzed which show that high egg yolk content causes an aggravation of reproduction in broiler breeder hens. The reduction in egg yolk content by means of selection may influence positively on reproductive traits of broiler breeder flocks not affecting the broiler meat performance.

Key words: meat-type poultry, egg nutrients utilization, reproduction, growth, egg weight.
