ANALYSIS OF THE FORMATION OF THE BREEDING BASE OF GENETIC RESOURCES OF CATTLE OF THE SOUTHERN BEEF BREED

The dynamics of the number of subjects of the breeding business in livestock breeding of the Southern Beef breed, the total livestock and the number of cows for the period from 2002 to 2022 were analyzed. It was established that despite the fact that in 2022, compared with 2002, the number of breeding subjects in livestock breeding of the Southern Beef breed remained unchanged and amounted to 4, the total number of livestock decreased by 703 heads, including for 153 cows. An analysis of the use of Southern Beef breed bulls for natural mating of brood stock and a quantitative analysis of the available sperm production by year was carried out. It was established that in 2022, compared to 2002, the amount of sperm production decreased by 34.600 doses, and the number of sires from which it was obtained decreased by 12 heads. Based on the analysis of the level of operations of purchase/sale of breeding animals of the Southern Beef breed for 20 years, an annual predominance of sales volumes over acquisition volumes was noted, with the exception of the indicators of 2010 and 2018. It was established that in order to maintain the competitiveness of the southern meat breed, selection and breeding work with it at the current stage and in the future requires the development of methods for preserving the gene pool.
