Peculiarities of raising orphan calves of the Aberdeen-Angus breed

Beef forms the basis of meat production resources in the country's farms. However, as calculations show, in the future, as the level of milk productivity of dairy cows increases, a certain deficit in beef will appear, which can only be replenished by beef cattle. Aberdeen Angus cows are caring mothers, so calves have a strong immune system and very rarely get sick; at the same time, during calving, the mother cow sometimes dies or cows refuse to feed newborn calves. In this case, to preserve the number of calves on the farm, artificial feeding of orphan calves is used with whole milk substitutes. The calves of the experimental group were fed with milk replacer - SPRAYFO BLUE until 4 days old.Then we used CCM - SPREYFO RED. The live weight of calves in the control and experimental groups at birth did not have significant differences and averaged 22.55 kg. Live weight at the age of 30 days old was slightly higher in calves of the control group compared to the experimental group by 1.1 kg or 2.4%. The same trend was observed for the live weight of calves at the age of 60 days old. Over the entire growing period from birth to 2 months old, the average daily gain was higher in calves in the control group and amounted to 774 g, which is 33 g or 4.3% higher than in calves in the experimental group. Analysis of the data obtained indicates that raising orphaned Aberdeen Angus calves using whole milk substitutes is quite acceptable in the conditions of this farm.
