Study of economic-biological indicators of perspective hybrid lines of bread wheat

Abstract

The management of ontogeny in sheep is the most important problem in biology and zootechnics, because productive qualities depend on the pattern of growth and development. The method to rear fat tailed lambs in the suckling period was developed in Kazakhstan. The method increases productivity of lambs during this period, due to the method the body weight of 4-month old ewes is 36.6-37.4 kg, the total gain - 26 kg, the body weight of rams is 38.5-39.7 kg, the total gain - 27.3-28.0 kg. The tests were conducted in "Bakdaulet” in Kyzylorda region. Coarse-wooled fat-tailed sheep were transferred to this farm from breeding livestock farm in Aktobe region. The test was carried out on Kazakh fat-tailed sheep. The articled presents the results of the study of growth and development of lambs. In Priaralye, the highest growing capacity of Kazakh coarse-wooled fat-tailed lambs was recorded at the beginning and at the time of weaning. The growth was more intensive in the length of the body than in the height at the withers. During the period from birth to weaning, the lambs grew wide. Thereby, at the age of 4 months, animals seemed to look more compact.
