Research has been carried out on the intensive production of beef when raising dairy bulls up to 12 months of age drinking mainly dairy feed in the first 5 months of life (in group 1) and with the inclusion of a starter compound feed in the diet (in group 2). Different types of bull calves rearing in the first 5 months of life led to significant differences in the growth and development of the whole organism and all its individual organs and tissues, mainly in favour of bull calves raised with replacing part of the milk with vegetable feed, and subsequently had a decisive influence in the period from 6 up to 12 months of their life with the same type of feeding and maintenance. It has been established that the rearing system with a decrease in the drinking of whole milk and abstinence of the supply of roughage for the first 2 months of life, promotes the the growth of animals for a twelve-month period of life, leads to an increase in the yield of veal and beef meat, a decrease in feed consumption per unit of weight gain, and increasing the profitability of production by 8-9%, therefore it is recommended for production.
