ЕСТЕСТВЕННАЯ РЕЗИСТЕНТНОСТЬ И ВОСПРОИЗВОДИТЕЛЬНЫЕ КАЧЕСТВА СВИНЕЙ В УСЛОВИЯХ ПРОМЫШЛЕННОЙ ТЕХНОЛОГИИ

Abstract

Resistance characteristics in Yorkshire and mixed bred sows routinely raised at the farms of Russkaya Svinina Millerovo, Ltd situated in the Millerovo District of the Rostov Oblast and running on the machinery by Spanish Covenco, and Russkaya Svinina CJSC of the Kamensk District to the same Oblast, running machinery by German Big Dutchman in accordance with breeding scheme adopted there. It was found that the sows in the test Group 1 farmed using Cavenco machinery had higher reproductive capacity than their mates in the test Group 2 which was farmed with Big Dutchman machinery. The first group of sows had higher resistance measurements than Group 2 ones too; thus active white blood cells count was higher by 1.7%; phagocytic number was higher by 0.32 microbial count per one white blood cell; phagocytic capacity of blood was higher by 1.46.109; serum bactericidal activity in the Group 1 was higher by 8.79%, lysozyme activity by 1.12 times, complementary activity by 1.18 times, and by titer of natural agglutinin by 1.20 times. It was further established that intensive breeding technology adopted in farms served with either Big Dutchman or Cavenco machinery did not hamper natural resistance in sows and progeny.
