Evaluation of A Multi Enzyme on Apparent Nutrient Digestibility of Commercial Broilers

Evaluation of A Multi Enzyme on Apparent Nutrient Digestibility of Commercial Broilers

Materials and Methods Management of experimental birds The experiment was conducted at a Private Poultry Unit in Malayer, Iran. Corn bran used in the study was obtained from a local market. Polyzyme (Synergistically acting poly-enzyme complex produced from a single substrate by SSF technique) used for the study was manufactured and provided from Zeus Biotech Limited, Mysore, India. One hundred and fifty day-old broiler chicks (Cobb 500) used for the feeding trial were obtained from a local hatchery in Hamadan. The birds were given a commercial diet for 0 days after which they were randomly assigned to 5 dietary treatments with 3 replicates each. Each replicate had 10 birds. Five diets were formulated each for the starter and finisher phases. Diet 1 had no corn bran and served as the control. Diet 2 contained 202 corn bran and was supplemented with Polyzyme. Diet 3 contained 202 corn bran without the enzyme. Diet 4 contained 402 corn bran and was supplemented with the enzyme and diet 5 contained 402 corn bran without the enzyme. Polyzyme was added to the diets at the rate of 400g/tonne of feed. They were given the starter diets for 21 days after which they were switched to the finisher diets which they were fed for another 29 days.
