Chernjuk S. Enhancement of individual elements technology growing dairy calves in the milk period

The paper describes theoretical and experimental materials of repair calves technology under conditions of use canned colostrum and milk replacers. There are changes in trend productivity of calves. There has been put research in assessment of morphological and biochemical composition of their blood, dynamics of growth and development patterns of the type of physique, adaptable, resilient body and given the economic efficiency of the proposed technologies for growing calves. The process of freezing did not have a significant impact on the quality and composition of colostrum, and the introduction of this technology made it possible to feed summer, better colostrums to calves that were born in winter-spring period. Theoretically grounded and experimentally proved that the use of milk replacers in accordance with the proposed technology significantly affected the increase of live weight, saved time and money costs per unit of growth. The new data on the positive impact weaning canned colostrum by calves had found out. This was in the first days of postnatal period, and also proved that the use of substitutes for whole milk and condensed during the growing repair heifers to 6 months of age compared with the traditional pattern of breeding. This did not cause negative changes in the mechanism of resistance on the organism of animals.
