Effect of the varoius qantitive feeding program on the grow, evolution and performance of broiler breeder

In order to studing the effect of various quantitive feeding restriction programs on the growth and performance of broiler breeder diets .this experiment was carried out.One hundred and sisty lohman male and one hundred and sisty lohman female commercial two weeks old with similar weight were divided in 8 treatment (4 quantitative feed restriction programs in both male and female sexs of lohman strain) wight 4 repetition.The statistical design was Compeletly Random Design(C.R.D).The diets was isocalaric and isonitrogenous .. Feed intake content according to lohman broiler breeder management guide and as controlled was the same for all feed restriction program. After the end of the breeder period,(22 weeks) males and females mixed in each of feed restriction programs ratio 1 to 10 in breeder period, body weight , uniformity percentage. Feed efficiency and required feed content determined for achieving the same weight were measured. The obtained results showed that the body weight, coefficient variation, and body weight uniformity percentage, and feed efficiency affected (by) feed restriction program and sex (PO.05), but feed restriction program intraction with sex was not significant for the traits (PO.05). By assessing egg production, settable egg production, fertility, hatchability, embryo mortality rate, marketable chicks percentage, feed intake per production unit (settable egg and production chick) determined the performance of each feed restriction program. The obtained information showed that settable eggs percentage, fertility rate, embryo mortality rate and total feed intake per each chick production affected by feed restriction program in breeder period. The obtained results of the experiment showed that skip-a-day feed restriction perform in breeding period caused the better control and the increase in body weight uniformity in sexual maturity and increase settable egg percentage, fertility percentage, hatchability percentage in production period. In birds treated by skip-a-day feed restriction, lymphocyte percentage reduced and hetrophil to lymphocyte ratio increased . Also the highest percentage of males' bodies weight uniformity get at the end of breeding period in five days to week program and in female in six days to week program. However, there was not significant different in fertility percentage and hatchability percentage among birds, by six days to week, five days to week skip-a-day feeding program, and the highest percentage fertility and hatchability observed in five days to week program .
