Breeding bull, Live weight, Metabolizable energy

This article presents scientifically substantiated feeding standards for breeding bulls

depending on their live weight, age, body condition score, and intensity of use during the breeding

period. The inclusion of pelleted feed products in the ration is analyzed as a modern technological

solution aimed at improving nutrient balance, increasing feed utilization efficiency, and enhancing

reproductive performance. Requirements for metabolizable energy, digestible protein, calcium,

phosphorus, and microelements are described. Ration structures for winter and summer seasons are

systematized, and recommendations are given for optimizing the sugar–protein ratio and crude fiber

content. The research results demonstrate that the use of balanced pelleted concentrate feeds ensures

stable physiological status in breeding bulls, increases sexual activity, and improves semen quality.
