| Abstract |
This work was conducted to study the effect of feeding high dietary energy levels on productive performance of broiler chicks during the finisher period. Two hundred and forty unsexed Hubbard broiler chicks at four weeks of age were divided into four treatments (60 bird each); each treatment contained 6 replicates of 10 birds.
The experimental treatments were as follows:
1: Chicks were fed diet containing 3135 Kcal/Kg diet from 22 to 42 days of age. 2: Chicks were fed diet containing 3320 Kcal/Kg diet from 22 to 42 days of age. 3: Chicks were fed diet containing 3320 Kcal/Kg diet from 29 to 42 days of age.4 : Chicks were fed diet containing 3320 Kcal/Kg diet from 36 to 42 days of age.
Results obtained could be summarized in the following:
No significant difference among dietary treatments was recorded for live body weight but significant improvement in live body weight gain between 22 and 42 days of age were observed. The high energy diets significantly affectedfeed intake (FI) during the period from 22 /0 42 days. Chicks fed the control diet had lower FI value during this period. while chicks fed the diet containing high dietary energy levels (3320 kcal/kg diet for two weeks) had highest FI value during the same period. No significant difference among dietary treatments in growth rate; performance index and chemical composition of broiler meat and carcass traits were observed. The results indicated insignificant effects of high dietary energy levels on serum constituents except that total protein and globulin had significant effect. Economical efficiency ralue a/ 6 weeks of age was improved with broilers fed high energy diet (3320 kcal/kg diet) for one week as compared with the control group.
In conclusion, feeding a high energy diet (3320 kcal/kg diet) resulted in greater gross feeding margins with broilers fed for one week (36 to 42 days).
