Abstract
The aim of the study is to determine the live weight of Karakul sheep of Karakalpak suras of different ethological types in different physiological periods, the live weight of offspring and the relationship between these indicators. The study was conducted at Ltd “Istiklol karakul naslchilik”. During the study, the reaction of feed conversion was taken into account when classifying sheep according to ethological types. The live weights were measured on electronic scales. The data was processed biometrically. We studied the indicators of sheep’s live weight during the second period of lambing, the first period of lactation, the second period of lactation and after leaving the lactation period. These results were compared with the live weight at birth of their offspring. The results of the study showed that the live weight of the first ethological type of sheep was high in all physiological periods, and their offspring also had a higher live weight than their peers. The results of the study can be used in breeding in order to create herds that allow receiving the offspring with high live weight. The results of studies of the relationship between the live weight of the Karakalpak suras of Karakul sheep of different ethological types in different physiological periods and the live weight of their offspring are presented.
