| Abstract | ||
| The objective of this study was to determine Evaluation of induce molting for same bone factor for commercial laying hens ISA Brown . Total of 360 Isa Brown layer hens 63 weeks old, were randomly divided into six treatment groups. Hens in each treatment group were subdivided into three replicates and reared on the floor throughout the experimental period which was lasted for 36 weeks. The six treatment group were as fallow: T1: Control group fed on commercial layer diet ad libitum. T2: Force molting by starvation for 10 days. T3: Force molting by starvation for 2 days and fed 45 g/hen/day on altrative days. T4: Force molting by high dietry zince. T5: Force molting by alfalfa meal ration. T6: Force molting by barely grain ration. Tibia and Femur dry weight ,ash weight, of control group T1 was significantly greater thanT2 and other groups , this decrease in bone quality occurred in all molted hens. | ||
