EFFICIENCY OF WHOLE MILK REPLACER WITH DIFFERENT PROTEIN RATIO IN FEEDING CALVES AGED 10-30 DAYS

Abstract

Healthy, well-developed young animals with high growth rates, capable of using feed efficiently is one of the main challenges facing the livestock industry. In this regard, the aim of the research was to establish the most efficient amount of protein in whole milk replacers for calves aged 10-30 days, which have a positive effect on physiological state and productivity of animals. As a result of research, it has been determined that the most efficient amount of protein was 22 and 25% in whole milk replacers for calves aged 10-30 days, contributing to increase in average daily weight gain by 11.1 and 12.2% while reducing feed costs by 10.6 and 18.2 percent.
