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.
