Maintenance and feeding of dairy calves raised for meat using whole milk substitutes (ZCM) from different producers

The work examines the technology of raising young cattle for meat. The procedure for receipt, acceptance, accounting, maintenance, transfer of calves to sectors, distribution of bedding, collection of manure. Raising dairy calves on the territory of the Feedlot joint venture occurs in several stages. At the first stage, animals are kept in sector “C 1” for up to 60 days in individual boxes. After reaching a live weight of 85-120 kg, they are transferred to group housing in calf barns in sector “C 2” (61-90 days of housing), where the animals are kept for 30 days. At the next stage, the calves are transferred to sector “C 3” (91-150 days of housing). At the age of 150 days, the animals reach a weight of 200-220 kg and are transferred to the fourth sector “C 4” (151-340 days of housing). At the final stage in sector “C 5” (341-450 days of housing), the animals weigh 550-600 kg. Until recently, feeding calves from 15 to 60 days was carried out with Proteinmol milk replacer, but supplies of Proteinmol milk replacer are being stopped. The farm is looking for alternative replacement options. For this purpose, an experiment was carried out on feeding “Norma” replacer produced by EcoTrade LLC; the company’s goal is also to improve the composition of “Norma” replacer. According to the results of the experiment, the average daily gains of calves on the new milk replacer "Norma" are lower than on the previous milk replacer "Proteinmol". However, the use of “Norma” milk replacer for the farm is economically beneficial, since the cost of 1 ECU of the diet and the cost of feed spent per 1 kg of growth are reduced. Saving feed costs per 1 kg of growth is 0.38 rubles. By improving the composition of the “Norma” milk replacer, in the case of an increase in average daily growth and its fixed price, feed costs per 1 kg of growth will decrease. The savings in feed costs per 1 kg of growth will be 12 rubles.
