Abstract:
Zinc as Zinc Oxide at three levels (15000, 20000 and 25000ppm) with or without
vitamin C was used as a method to induced molting of 296 Arbor Acres broiler breeder
at 375 days old. Hens were randomly divided into eight treatments. Two treatments (T1
and T2) were free of Zinc included control with or without (1g/ kg) vitamin C; three
treatments (T3, T5 and T7) included different levels of zinc (15000, 20000 and
25000ppm Zn as ZnO) without vitamin C; while, (T4, T6 and T8) included different
levels of zinc (15000, 20000 and 25000ppm Zn as ZnO) with (1g/ kg) vitamin C addition.
Postmolting periods were divided into 6 periods. All treatments and post molting
periods had significant (P<0.05) effects on egg production traits. Hens in T4 significantly
(P<0.05) better in most egg production traits. While hens in T8 had significantly
(P<0.05) higher egg weight. Hens in T1 and at period 1 had significantly (P<0.05) lowest
feed efficiency compared with others. Results also indicated that highest weight of eggs,
number of eggs/ hen and cumulative egg/ hen for all treatments occurred during the
Period 6 followed by Period 5 and 7 and the lowest number and cumulative egg/ hen was
at Period 1 and 8.

Key words: Zinc Oxide, vitamin C, molting, Broiler Breeder hens, egg production traits.
