Abstract:
The study on 2 groups of 22 440 chickens, divided into a control group and an experimental group, assessed the influence of ”Rescue Kit® SL” (containing B. licheniformis and B. subtilis, betain, vitamins and oligo-elements) in the drinking water from 9 to 14 d of age. Findings: - reduced the lethality rate amounted to 3.5% in the experimental group and 3.9% in the control group. The body weight was 50 g higher compared to chickens in the control group. Some biochemical indices tended to increase in broiler chickens in the experimental group.
