Evaluation of Some Commercial Growth Promoters on the Performance and Carcass Quality of Broiler Chickens

Abstract

This research was conducted to compare between growth promoters Zigbir (commercial herbal product), Biogine (Probiotic) and X Mos (Yeast) on the growth performance and carcass quality of broiler chicken. One hundred twenty eight one week-old unsexed broiler chicks of Arbor Acres hybrid were randomly allotted to four experimental diets: 1- control (basal diet), 2- basal diet plus Zigbir, basal diet plus Biogine and basal diet plus X Mos Yeast, in a complete randomized design. Each treatment contained 32 chicks (8 birds/ replicate). Feed intake, Body weight gain and feed conversion ratio were recorded weekly. On the 35th day 4 birds per treatment were slaughtered and the weights of carcass, carcass cuts and edible organs of individual birds were measured. Results of this study revealed no significant (P > 0.05) improvement of performance, carcass yield, carcass cuts and edible organs of broiler chicken by the dietary supplements compared to the control.
