Abstract:
The study on 2 groups of 15 500 chickens, divided into a control group and an experimental group, assessed the influence of Avizyme 1500 (xylanase, protease, amylase, and pectinase) in the feed from 1 to 48 d of age. Findings: - reduced the lethality rate amounted to 2,3% in the experimental group and 2,7% in the control group. The body weight was 7% higher compared to chickens in the control group. Some biochemical indices tended to increase in broiler chickens in the experimental group.
