245			_aEffect Of Enzyme Supplementation And Strain Of Broiler On The Meat Production Efficiency Of Broiler Chicks
260			_c1995
502			_aThe project was designed to study the effect of enzyme (Kernzyme) supplementation on the performance of two broiler strains (Hubbard and Arbor Acres). One hundred and twenty day old chicks of each strains were purchased from respective hatcheries, The starter rations were fed upto 28 days and finisher rations were fed upto 35 days. Non-significant difference was observed between control and enzyme supplemented rations in weight gain, feed consumption and feed efficiency. Whereas significant. difference was observed in weight gain and feed consumption between the broiler strains. While non-significant difference was observed in feed efficiency between the strains. A significant difference was observed between broiler strains, control arid enzyme supplemented rations in dressing percentage. A non-significant difference was observed in chemical composition (moisture, protein and ether extract.), of lean breast meat. between broiler strains, control and enzyme supplemented diets. The study revealed that Kemzyme supplementation did not. improve the performance of broilers. Whereas Hubbard strain has significantly (P<O.O1) higher weight. gain, feed consumption and dressing percentage than Arbor Acres. While Kemzyine supplementation has significant difference (P<O.05) in dressing percentage. The economic evaluation of the study revealed that Hubbard was the most economical than Arbor Acres strain. The cost of one kg live weight was lowest for Hubbard i.e. Rs.22.05. The control ration was the economic ration in this experiment. By supplementing the enzyme, the cost of ration was increased and cost of producing the live weight by enzyme supplemented ration was increased as well. The results of the present study proved that the use of Kemzyme is uneconomical and Hubbard strain is the better strain which behave perfectly well Pakistani environmental condition.
