Abstract
At present, it is important not only to assess the effect of milk replacers on the growth of dairy calves, but also the technology of their feeding, in particular the use for their preparation and presentation of technological equipment. It was established that the consumption of milk substitute did not have a negative effect on the growth rate of bulls within two months. The live weight of calves at the beginning of the experiment did not differ significantly from one another. It was at 39.5–40.3 kg, which indicated an optimal selection of calves for the experiment (P> 0.999). Average daily weight gains in the second and third study groups were higher by 1.6% and 0.8%, respectively, compared with the control group. The hemoglobin content in the bulls I of the experimental group was higher by 5.1 g/l (P> 0.95), the second – by 3.6 g/l (P> 0.95), compared with the control group. The hemoglobin content of the bulls of the first experimental group was higher by 5.1 g/l (P> 0.95), the second – by 3.6 g/l (P> 0.95), compared with the control group. All other blood parameters were within the limits of physiological norms. Thus, studies have shown that the use of milk substitutes provides a sufficient level of growth of young animals and reduces the consumption of whole milk.
