Feather loss and egg production in broiler breeders and layers

Abstract

The relationships between various parameters of the laying cycle and feather loss from different parts of the body were studied in broiler breeders and layer hens. The pattern of feather loss was similar in both types of bird and was most pronounced on the breast. In both the broiler breeders and layers, there were significant negative correlations between overall feathering and egg production at 52 weeks of age and significant positive correlations between overall feathering and age at first egg. Other relationships between feathering and parameters of the laying cycle were more pronounced in the broiler breeders than in the layers, even though the former laid fewer eggs.
