Abstract
The article presents material on the growth and development of crossbred lambs (MSHK x KKPG) raised in the Ukrainian LLP of the Ulan district of the East Kazakhstan region. The productivity of young sheep was evaluated and studied. The growth and development of young sheep, their exterior indicators, and the assessment of their live weight dynamics, slaughter indicators, fattening, and meat qualities of the first-generation crossbred young sheep (MWK x KKPG) were studied. As part of the study, the measurements of the lambs at birth were taken, and their body structure indices were calculated. A comparative characteristic of the productive and hematological features of crossbred offspring with sheep of the original maternal breed is given. The young of the current year were preliminarily tested when they were weaned from their queens at the age of 4-4.5 months and the test data of 10 breeding sheep for the quality of offspring were processed. It was found that the first-generation crossbreeds had good meat and wool qualities, the coat and wool quality were (50-48 quality) and (48 quality). The slaughter indicators and meat qualities of 4-4.5-month-old lambs of different genotypes and their morphological composition of carcasses showed an optimal ratio of muscle flesh and fat in the carcasses. The meatiness coefficient also ranged from 4.46% to 4.24% for the groups. Industrial crossbreeding involving the Kazakh fat-tailed semi-rough-haired breed and the Kazakh meat-and-wool semi-fine-wool sheep (MWK) in the conditions of the Ukrainian LLP in the Ulan district of the East Kazakhstan region is a highly effective tool for increasing productivity, wool quality, and profitability in sheep farming.
