Granulated mineral complexes in the rearing of young rams

Abstract

The purpose of the work was to increase the meat productivity of sheep when introducing granulated mineral complexes produced by the Azot Branch of URALCHEM JSC into their ration. A scientific and economic experiment was carried out on the herd of sheep of Volgograd meat and wool breed. Four groups of young rams with 10 heads in each were formed. The experiment was carrier out for 4 months – from 4 to 8 months of animal age. The animals of the control group were housed on a general farm ration. Their analogues from the experimental groups were fed a mineral compensating additive instead of the mineral part of the ration: the 1st experimental group recipe No. 1, the 2nd experimental group recipe No. 2 and the 3rd experimental group recipe No. 3. It was revealed during the physiological experiment that the organism of animals from the experimental groups compare with the control group absorbed nitrogen obtained with compound feed somewhat better. The highest nitrogen utilization rate was found in sheep that consumed the mineral granulated balancing additive made according to recipe No. 1. It was found that the sheep of the experimental groups, whose rations included the mineral granulated balancing additive had a higher growth rate. The best results were obtained when using the mineral complex made according to recipe No. 1. The profi t from the sale of mutton produced during the experimental period in the 1st, 2nd and 3rd experimental groups exceeded that in the control group by 224,9; 114,5 and 73,8 rubles. The level of profi tability of meat production in the experimental groups was higher than that of the herdmates of the control group by 11,21, 6,41 and 4,10 abs.%, respectively. Thus, in order to increase the meat productivity of young rams we recommend using a diet using mineral granulated complexes. We consider the most optimal complex made according to recipe No. 1.
