PRODUCTIVITY AND BIOLOGICAL FEATURES OF PIGS OF DOMESTIC AND CANADIAN BREEDING

In the conditions of large pig breeding complexes in the raw material base of Smolmyaso OJSC andPavlovskaya Sloboda Meat Processing Plant OJSC, in the period of 2010-2015, research and production experiencewas conducted to study the productivity and biological features of domestic and western breeding pigs. Experimentalyoung stock from 2 months age till reaching the live weight of 100 kg was kept in the control growing. Theconditions of keeping, feeding and slaughter of young pigs were identical. When young pigs reached 95-105 kg inlive weight, they were evaluated by their own productivity and slaughter indices.In the process of research, it was found that among the domestic and Canadian young stock, the highestprecocity and growth rate was characterized by three-breed hybrid young stock, obtained by crossing hybrid sowswith Duroc boars. The results of the control slaughter showed that among the domestic and Canadian young stock,the best slaughter indices were characterized by the three-breed hybrid young.It was established that the three-breed cross young pigs of the Canadian breeding reached the pre-slaughter liveweight 22 days earlier compared to the domestic one, the average daily weight gain was 134.1 g higher, the slaughteryield was 2.3% higher. Thus, the three-breed commercial young stock of Canadian breeding reliably surpasses thepigs of domestic breeding.The calculation of the economic efficiency of growing young pigs shows that the additional income from thesale of 1 head of Canadian breeding is 1.5 thousand rubles (23 US dollars) compared with the domestic breeding.Based on the research results, it was recommended that pig farms engaged in breeding and growing domesticpigs, should strengthen breeding to improve the fattening and meat qualities of pigs. To obtain commercial youngpigs with high fattening and meat qualities, it is recommended to use Canadian pigs more extensively.
