Abstract
This article presents the results of research aimed at studying the effectiveness of a new formula for compound feed for lactating cows that includes non-traditional oilseed waste. The aim of the study was to evaluate the impact of the new feed on milk production and milk quality. The research was conducted at the Yntymak farm in a scientific and farming trial, with a control group and three experimental groups of animals matched for age, body weight, and physiological condition. Cows in the experimental groups received a diet containing the developed feed, while animals in the control group were kept on the farm's standard diet. The studies revealed that the use of the newly developed feed increased milk production. The highest average daily milk yield was observed in cows in the second experimental group, reaching 23.2 kg, 16% higher than in the control group. Improvements in milk quality were also observed, including an increase in the content of complete protein, a key indicator of its nutritional and biological value. The highest protein content was recorded in the milk of cows in the second experimental group. Overall, the experimental group animals outperformed the control group in key physicochemical milk parameters. The use of compound feed with the inclusion of non-traditional raw materials allows for a reduction in the proportion of grain components, a reduction in the cost of feed, an increase in its biological value and an environmental efficiency of production.
