Implementation of non-traditional feed additives in cattle breeding of Yakutia

Abstract

The results of research and production experiment on the use of local non-traditional feed additives in the feeding of Simmental first-calf heifers in the Republic of Sakha (Yakutia) have been presented in the article. A series of scientific and economic experiments have already been conducted to determine the norms for including local non-traditional feed additives in the rations of cattle, but they The results of research and production experiment on the use of local non-traditional feed additives in the feeding of Simmental first-calf heifers in the Republic of Sakha (Yakutia) have been presented in the article. A series of scientific and economic experiments have already been conducted to determine the norms for including local non-traditional feed additives in the rations of cattle, but they were not sufficient for the rational use of these feed additives. In order to determine the effectiveness of the use of local feed additives a scientific and economic experiment has been carried out under the environments of the APC “Krestyakh” in the Suntarsky district. Two groups of first-calf heifers have been selected per 50 heads in each. The groups have been formed by using the method of analogues. The environments of housing in all groups have been the same. The difference was that the experimental group of first-calf heifers have received from the local unconventional feed additives (zeolite khongurin, sapropel and Kempendyaskay salt). The results of the production test have shown that the experimental group of first-calf heifers exceeded the control group’s analogues in terms of milk yield by 233,4 kg or 9,4 %. Experimental group of first-calf heifers has had more high content of fat in milk 0,17 abs.%. When recalculating the content of fat in milk for 4 %, the difference in gross milk yield between the groups was 16,73 t or 14,3 % in favor of the experimental group. Economic analysis of the results of research and production experiment has shown that there was a significant difference in profit between the groups. So, in the control group it was 462 247,46 rubles, and in the experimental group 528 444,43 rubles. Additional profit in the experimental group was equal to 66 196,97 rubles, while the level of profitability was 8,2 %. Thus, the results of the research have shown that first-calf heifers of Simmental breed that received local non-traditional feed additives had higher milk productivity.
