    The Effect of Proactive Enzyme with Finisher Feed on Performance and Meat Quality of Broiler Chicken
    (Uva Wellassa University of Sri Lanka, 2016) Vithana, V.P.K.H.A.
    An experiment was conducted to investigate the effects of dietary poultry by product meal (PBM) 5% with or without protease enzyme on growth ,carcass characteristics and meat quality parameters of Arbor acre plus broilers. One hundred and twenty birds (n=120) were fed experimental diet from 21 day to 35 days, 1 to 10 days and 11 to 21 days broiler pre starter, broiler starter were fed respectively .In there poultry by product meal (5%),exogenous protease (with and without ) was undertaken using factorial arrangement under completely randomized design. The birds (n=120) were randomly divided into 12 replicates (10 birds/replicate) and 60 birds allocated for each treatment. PBM along with supplementation of 5% exogenous protease significantly improved growth performance of broilers .The body weight gain ,FI And FCR were increased [p <0.05] from 21 to 35 days by the enzyme treated diet. No significant differences in lengths of small intestine , breast weight, thigh weights. No significant differences in pH , water Holding capacity, Cooking loss. In conclusion, protease enzyme added poultry by product meal enhanced the weight gain and performance of broiler birds . Key words: Protease enzyme;carcass charateristics;PBM;broilers
