Abstract :
Food shortages may be among the most significant negative consequences of overpopulation. In order to meet
the nutritional needs of livestock origin, the number of available animals cannot be increased; however, ways
must be sought to increase production per livestock unit. Livestock breeding is the science and art of
establishing genes that are effective in the economical production of livestock, which creates superior livestock
and poultry. The quality of the main stock of animals, the characteristics of the initial population according to
the main characteristics of breeding, biological and internal characteristics, biochemical parameters of sheep
blood with different genotypes, and its economic efficiency have been studied to achieve the aim of the present
study. The animal subjects in this study were the South Caucasian merino sheep (Group I) and the mixed breed
sheep (male of Australian merino x female of South Kazakhstan merino) (Group II). The age-related changes in
the body weight of the resulting offspring were studied by weighing them at birth and 4, 7, and 18 months of
age. Moreover, external body mass measurements were taken from these animals at the same time. In addition,
absolute, daily average, and relative increases in their live weight were determined based on the weighting data
and the considered blood parameters. According to the results of the present investigation, relatively high values
of variability coefficients of blood acid capacity, globulin content, aldolase activity, alkalinity, and acid
phosphatase were reported. The levels of total protein, albumin, globulin, and haptoglobin of the second group
were 7.42%, 27.64%, 12.9%, and 9.7%, respectively, which had a significant increase, compared to those in the
first group (P<0.05). The scientific research data are reflected and proved in this paper, which can serve as a
specific contribution to zootechnical science to use the breeding-tribal work in practice and conditions of
different forms of ownership. Moreover, the results of this study can be useful in the improvement of breedingtribal
work and technology of high quality, compass well as competitive and ecologically clean sheep
production in the conditions of maximum year-round seasonal use of foothill and foothill-steppe pastures in the
south of Kazakhstan.
