Abstract
Two hundred and forty broiler chicks at one day old of both Cobb and Avian strains were used in this experiment. Chicks weighted and randomly divided into four treatment groups of three replicates (10 chicks) for each strain to investigate the response of broiler chicks strain to some growth promoters supplementation (Amio-Flash, Bio-Strong and Bio-Feed) on growth performance, carcass characteristics and some blood plasma constituents as well as economical efficiency.
The results indicated that:
Cobb chicks had consumed significantly higher amount of feed than Avian chicks. Broiler chicks fed diets supplemented with Amio-Flash recorded the highest values of live body weight (LBW), body weight gain (BWG), performance index (PI)and feed consumption (FC), also recorded best values of feed conversion ratio, protein conversion ratio (PCR) and calorie conversion ratio (CCR) than those fed other experimental diets. Interaction between strain and growth promoters supplementation had significant effect on LBW, BWG, PI and FC.
Percentages of carcass and total edible parts were significantly higher for Avian broiler chicks comparing Cobb chicks.
Cobb chicks had significantly higher plasma total protein, Globulin, cholesterol and AST constituents compared to Avian chicks., Also, cholesterol increased and A/G ratio decreased significantly by adding different growth promoters to the diets as compared to control. Interaction between strain and growth promoters supplementation had significant effects on all plasma constituents.
Feeding economical efficiency was improved for Cobb broiler chicks only by feeding diets supplementing with Amio-Flash than control. These results indicated that supplementing Amino-Flash as growth promoter to Cobb strain chicks could be used to maximize growth performance as well as economical efficiency without adverse effects on carcass traits during period (0-5 wks of age).
