| Summary: | Abstract The work is aimed to develop innovative ways to increase effectiveness of a process of acclimatization and adaptation of the Hereford breed youngsters of Siberian selection, to increase its beef productivity, to enhance its usage of nutrient materials in the diet through inclusion to the diet of animals the local mineral feed supplements (Hongurin’s zeolite and putrid mud) with mineral salt that compensate a deficit of mineral materials in the diet. The number of hemoglobin was larger in the experimental groups of animals than in the control group of bull-calves, which demonstrates better metabolic processes. Balance of nitrogen, calcium, and phosphorus in every studied group was positive. High rates of the usage of nitrogen, calcium, and phosphorus, from taken to digested, were in the first and the second experimental groups of bull-calves. The usage of the local mineral feed supplements in the Hereford breed bull-calves’ diet provided increasing in their digestibility of nutrient materials, such as, in average, crude protein by 2,63 and 2,78%, crude fat by 2,32 and 3,24%, crude fiber by 1,77 and 3,27%, nitrogen-free extractable substances by 5,12 and 8,40%. Higher indicators of fixed nitrogen, calcium, and phosphorus from taken to digested were in the first and the second experimental groups of bull-calves. Results of the experiment established relevance and effectiveness of the inclusion in the diet the local mineral feed supplements for the Hereford breed bull-calves. |
