Dietary Effect of Enzyme Mixture in Diet on Broiler Performance
Keywords:
broiler, enzymes, bodyweight, weight gain, feed conversion, triglyceridesAbstract
Two hundred Cobb 500 chickens were used as a material in the study. Animals were divided into four groups, control and three experimental groups fed with three different levels of enzyme cocktail (0,05, 0,1 и 0,15%) for 42 days. Diets were formulated to meet nutrient requirements of this chicken category with no differences regarding the content of energy and proteins.At the end of the experiment body weight, weight gain, feed conversion ratio and total serum triglycerides level were measured.As a result, it was concluded that the supplementation of an enzyme cocktail expressed no significant effects on production performances without matter of its concentration. Enzyme levels of 0,1 and 0,15 significantly increased triglyceride content in broilers blood serum.
