Abstract
This experiment was conducted to investigate the effect of adding three levels of (HMB-Ca) Beta-hydroxy-Beta-methylbutyrate Calcium to broiler diet on their productive performance and some carcass traits. A total of 216, day old Ross-308, unsexed broiler chicks were randomly distributed into 4 treatments with 3 replicates for each (18 chick/ replicate). Birds were dietary treated with HMB-Ca from day old until the end of experiment (35 day) as follows: T1control group without any addition, T2: basal diet with 0.1% HMB-Ca, T3: basal diet with 0.15% HMB-Ca and T4: basal diet with 0.2% HMB-Ca. Results showed that T4 significantly (P<0.01) improved feed conversion ratio, increased (p<0.05) the productive index at 5 weeks old and reduced (P<0.05) the weekly feed consumption as compared to control group. Furthermore, T4 didn’t record any mortality percentage during the experimental period. Concerning carcass characteristics, results showed that dressing percentage% and relative weights% of giblets (heart, liver and gizzard) didn’t affected significantly due to experimental treatments whereas the relative weight of abdominal fat was decreased significantly (P<0.05) in T4 as compared to control. From recent study we can concluded that broiler chickens dietary fed with 0.2% HMB-Ca reveled to a very important economic results with good quality concerning the improving of feed conversion ratio, increasing in the productive index, and reducing the abdominal fat
