INFLUENCE OF ABIOTIC FACTORS ON THE POSTEMBRYONIC PERIOD OF LAMBS DEVELOPMENT DURING THE YEAR
Abstract
The article presents the materials obtained as a result of the study of the influence of abiotic factors during the year on the growth and development of lambs. It was found that they are quite adapted to the unstable weather of spring, hot summer, moderately growing until autumn, in winter with high viscosity and decline. The offspring of sheep in winter and early spring refers to the progressive method of cultivation. Offspring born in winter and early spring are resistant to summer heat. The difference between winter and spring lambs at birth is 11.6%, and at weaning from the mother-3.2%. In addition, at the age of 4.5 months, lambs have the highest slaughter yield (49.8-52.0%). The Karakul farms of the Suzak region have not been sufficiently studied about the influence of the term of lambing animals on the growth and development of the resulting offspring. During this period, the average daily weight of young animals born in early spring was 309.0 g, born in the spring-300.0 g .. However, in General, the live weight of lambs from birth to 2 months of age increased by 5.07-4.7 times, respectively.
