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.
