Effect of liquid feed additive "Reasil® Humic Vet" on nutrient digestion in poultry farming

Abstract

Reasil® Humic Vet is a liquid water-soluble feed additive with complex action. The aim of our research was to study the effect of the liquid feed additive "Reasil® Humic Vet" on the productive qualities and the digestibility of nutrients in compound feed by laying hens. The drug was drunk for 14 days with a break between courses of 7 days at a dose of 0.25, 0.50 and 0.75 ml / 1 liter of water. The highest egg production was obtained in chickens, the second experimental group -84.69%. The weight of 1 egg in this group also turned out to be higher than -63, 10 g. All this led to an increase in the egg weight to 31.09 kg, while reducing feed costs to 2.17 kg. The digestibility of organic matter in the experimental groups was 75.45, 75.44 and 75.37%, which is significantly higher than in the control group by 0.66, 0, 67 and 0.59%, respectively (P <0.05). The drug used with a high degree of reliability stimulated an increase in the digestibility coefficients of protein, fat, fiber (P <0.01) in chickens from 1 and 2 experimental groups. Increasing the amount of the supplement to the maximum dose did not significantly affect protein digestibility. Fat, fiber and dry matter in general in the 3rd experimental group had digestibility coefficients, the difference of which with those of the control group was confirmed by biometric processing (P <0.05 and 0.01).
