Abstract
This study investigates the effect of different body weight of Arbor Acres broiler breeder
hens after molting on product performance. 296 hens, the birds were molted by zinc oxide
with or without supplementation of vitamin C and the body weight of the birds after
molting at 361 days old of age, were randomly divided into eight treatments (T) of body
weight: [T1(3.783), T2(3.714),T3( 3.458), T4(3.428), T5(3.380),T6( 3.318), T7(3.276)
and T8(3.253) ±50]. Weekly eggs/hen, hen day production and egg mass revealed
significant (p<0.05) differences between different body weights of hens. Hens in molting
significantly had higher values of these traits compared with non-molting hens. Effect of
body weight on Fertility percentage of eggs did not differ while hatchability of fertile
eggs and hatchability of total eggs affected by the different treatments with the superiority
of molting treatments on non-molting treatments. Results show no significant effect of
body weight on egg weight and chick’s weight.
