ГУМИНОВАЯ КОРМОВАЯ ДОБАВКА В РАЦИОНЕ КУР-НЕСУШЕК

Abstract

The studies were carried out in the vivarium of FSBSI “Krasnodar Scientific Center of Animal Science and Veterinary Medicine”, in Krasnodar, on laying hens of Hisex Brown cross. The aim of the research was to study the effect of “Relikt A®» humic feed additive based on brown coal on productivity of laying hens of “Hisex Brown” cross. Four groups of young egg birds at the age of 130 days were formed for the research by the method of analogue pairs. The stabilization period lasted 10 days. Each group consisted of 40 heads. The experience lasted 3 months. It was found that there was a significant increase in the number of laid eggs per average laying hen by 14.9% in the group which received 0.06% of “Relic A®” of feed weight, compared to the control. Also, the application of the studied additive in the diets of laying hens of the groups that received 0.06% and 0.1% of the humic additive contributed to a decrease of feed costs for production of 10 eggs by 12.9 and 4.9%, respectively. Survivability of the population was maintained at the level of 100% in all groups throughout the entire experimental period. The oviposition intensity was significantly higher in the groups that received the humic supplement. The proceeds from the production of goods for a month increased in the control groups by 8.5; 14.9 and 4.8% according to the groups. The cost of 10 eggs decreased in the control groups by 8.3; 12.9 and 4.9%, respectively. The level of profitability also increased relative to the control in the second group by 6.53% and in the third by 10.13%, in the fourth by 3.82%. The feed additive based on brown coal can be considered as a natural feed ingredient; it is necessary to develop further a complex feed additive from natural components that fully satisfies the need of poultry for biologically active substances and micronutrients.
