Perfection of technology of micromineral nutrition of calves using selenium-containing soy protein |
|
|
The article presents the results of scientific and economic and physiological (balance) experiments on improving the technology of micromineral nutrition of young cattle. As a result of scientific and economic experience, a positive effect of selenium in the organic form on the dynamics of live weight and metabolism was established. So the higher growth rates were in the second test group, in which the calves were fed a diet containing selenium-rich soy protein. When studying the effect of different feeding conditions on the digestibility of nutrients in the diet, a physiological experiment was conducted, which established that calves from the experimental groups compared with the calves of the control group were better able to digest all the normalized organic substances. Thus, the digestibility of crude protein was highest in the second test group, whose calves were fed selenium in organic form. The highest digestibility of crude fiber was in the second test group. Morphological and biochemical indicators of blood were in the control and both experimental groups within the physiological norm. But the number of erythrocytes and hemoglobin in calves from the second experimental group increased to the maximum physiological norm. Thus, in calves' blood in both experimental groups, selenium was within the physiological norm, and in the control group it was significantly lower than normal. As a result of scientific and economic and physiological (balance) experiments it was proved that the use of selenium in soy protein in the form of selenomethionin in the feeding of calves helps the intensity of growth and metabolism.
