The article analyzes the growth and development indicators of young beef cattle. The research aimed to study the live weight of experimental steers and heifers in different periods of growth in a comparative aspect. To study the dynamics of weight growth in 6–8 months, 8–12 months, and 12–15 months, 20 bulls and heifers of the Kazakh white-headed breed were selected. The experimental animals were kept in equal conditions and on an increased feeding level at the rate of receiving an average daily gain of 800-900 grams in live weight. The research results indicate that steers and heifers had unequal live weight during all periods of growing and fattening. Consequently, the experimental bulls bred by intensive technology from 6 to 15 months of age had a live weight of 187.3–365.6 kg, heifers - 175.8–305.6 kg, which meets the requirements of the breed standard.
