Use of local non-traditional feed additives in cattle breeding in Yakutia
Implementation of the productive potential of cattle by finding new feed resources, such as zeolites and sapropels, opens up new opportunities to increase productivity and improve the physiological indicators of animals. Scientific experiments in different regions of the country have shown the effectiveness of feed additives that include zeolites and sapropels. Zeolites and sapropels of different deposits have different mineral composition. For this reason, the findings of the experiments have different economic results. There is a large zeolite deposit of Khonguruu on the territory of Yakutia, as well as a large volume of sapropel deposits. For this reason, their involvement in feed turnover is of scientific and practical importance for the region's agriculture. In order to determine the effectiveness of non-traditional feed additives, such as khongurin zeolite and local sapropels, a scientific and economic experiment was organized. Object of the research: fresh cows of the Simmental breed. The experiments were conducted at Krestyakh Farm of Suntarsky District in the Sakha (Yakutia). Scientific and economic experiments were conducted as follows: 3 groups of Simmental fresh cows were arranged using the method of analogues; the groups were divided into a control group and 2 experimental groups. Conditions of keeping for all experimental groups were the same, twice-a-day feeding. In addition to the main diet, the first experimental group consumed zeolite, the secondzeolite and sapropel. To control the physiological state of the animals, we studied the morphological composition of the blood of the experimental fresh cows. Findings of investigations showed that the inclusion of non-traditional feed additives in the daily diet of the fresh cows contributed to an increase in milk productivity by 7.20% and 9.34% (P>0.999), respectively. When translated in the terms of 4 percent milk, productivity was higher by 6.77% (P>0.99) and 9.03% (P>0.999). At the same time, all blood parameters of all experimental animals were within the established norms, which indicates a positive effect of non-traditional feed additives on animal physiology.
