Abstract
Results of conducted experimental research on studying of the influence of the local mineral feed supplements on growth, development and physiological indicators of the Hereford breed bull-calves allow making the next conclusions: Feeding of the local mineral feed supplements to the Hereford breed bull-calves allow increasing gaining in live body weight by 7,79 and 11,17%. Live body weight at the age of 15 months was amounted to 328,3-345,2 kg with daily average weight gaining at the entirety of the period of the experiment of 705,7-784,5 g. The usage of the local mineral feed supplements in feeding of the Hereford breed youngsters contributed to more intensive growth and development. In the background of the usage of the local mineral feed supplements in the diet of the experimental groups it was established that elevated concentration of hemoglobin in blood and all physiological indicators were within established normal limits. Increasing of productiveness in the experimental groups of animals was accompanied by reliable changes to the side of normalization of biochemical indicators of blood. Therefore, inclusion of the local natural mineral feed supplements to the diet provides increasing of beef productivity of the Hereford breed bull-calves and increases economical effectiveness of their breeding and fattening.
