In livestock breeding, particularly in sheep breeding, biotechnology of industrial technology plays an important role. A remarkable characteristic of technology is that it should be economically and biologically suitable. As a result, we are faced with the task of increasing grain yields and qualitative compositions of sheep. Ewes not having enough milk to feed their lambs after birth, result in malnourished lambs that grow poorly. Consequently, they become sick, and the rate of decline increases. Based on the analysis of the data, it appears that the variation in the live mass can also be attributed to ewes feeding, care, and behavior during the manger period. According to the research program, 2.5- and 5-month-old lambs were weighed. 2.5-month-old lambs had an average live weight of 17.0-20.51 kg for males and 15.10-18.13 kg for females. Compared to the live weight of newborn lambs (3.85 kg and 3.20 kg), the absolute weight gain of male and female lambs at 2.5 months was 16.66 kg and 14.93 kg, respectively. Lambs grain weight rapidly from birth to 2.5 months old (200-220 grams per day), which is typical for lambs in this age group. The data shows that lambs up to 2.5 months of age grew more rapidly than lambs 2.5-5 months of age, which was 12.69 kg and 12.09 kg, respectively, which is typical for lambs this age of multi-purpose sheep.
