Investigation of enzymatic preparation's effect on the broiler chickens growth and blood parameters

The chicken’s ration with probiotic enzyme preparation in a dose of 0.2 ml increases their live weight. Chickens received the preparation had a greater absolute weight compared to the control group. The absolute weight gain in the experimental group of chickens was 799.50 g, in the control group this parameter was 124.8 g lower and equal to 674.75 g. The preparation has a positive effect on hematological and biochemical parameters of blood. Thus, as a result of given investigations, we can conclude that application of preparations containing enzymes and a probiotic is safe for the broiler chickens and also increase live weight of birds.
