Impact of the feed additive “Hydrolactiv” on the growth and reproductive function of gilts during the period of growth

Abstract

In order to study the impact of “Velegard” on the efficiency of nitrogen and qualitative indicators of chicken meat, a research was conducted in 2014-2017. For the test there were 2 groups of Cobb-500 chickens, 100 animals each. The animals weighted 39.0-40.0 g. The tested group received mixed feed and water with “Velegard” on 6 and 7 days, and from 25 to 35 days of life. From 37 to 39 day, the chickens were given ascorbic acid at a dose of 50 g/t of water. The doses were calculated from the initial acidity of water. The feeding was conducted in accordance with established standards, age and rearing technology. It was established that “Velegard” and ascorbic acid administered in different periods of rearing had a positive impact on productivity, liveability and qualitative meat indicators in comparison with the control group. The body weight in the tested group was 49.33 g higher than that in the control group. The liveability of the tested group was 6% higher. The administration of the acidifier together with ascorbic acid during the final period of rearing had a positive effect on the protein content. The protein content in the white meat was 3.5% higher than that in the control group, in the red meat - 2.2% higher.
