Effects of stress factors on the performance of non-specific resistance and per-formance of piglets

Abstract

Feeding «feed mixture STO HA» piglets had a positive impact on their resistance and performance in the early postnatal period and the first week after weaning. Research has established that the content of total protein in pigs 4 day age 2nd and 3rd groups did not significantly different from the control group, while their peers from the 4th group born from sows that received «feed mixture STO HA» specified an indicator was higher by 2.8%. The level of total protein in piglet 2 nd, 3 rd, 4 th groups of 16-day age was higher by 5.8, 6.2, 8.8% (P < 0.05), respectively, in the control group, the 40th day age – significantly (P < 0.05) higher than same indicator 9.9, 8.6, 9.6% respectively. The difference in levels of immunoglobulin A in pigs receiving «feed mixture STO HA» (2nd and 4th groups) in 16 aged and performance of piglets 1st (control) group was 54.5 – 81.8% and was statistically significant (P < 0.05 – P < 0.01). The 28-day age and concentration of Ig A serum pigs 2nd and 4th groups significantly exceeded by 72.2 and 77.7% rate in the control group, the 40th day age at 60.6 and 54,5%, respectively (P < 0.05). The bactericidal activity of blood serum piglets 40 days old all research groups significantly (P < 0.05 – P < 0.01) greater than 15.9, 11.3, 14.8% performance of their peers in the control group. Lysozyme activity of blood serum pigs 2nd, 3rd, 4th groups and 28 days old dominated his peers likely group 1 15.3, 11.7, 15.6% in the 40-day age – to 19.0; 16.7; 19.8% respectively. Phagocytic activity of leukocytes in pigs 4 days old 4th group born from sows that received «feed mixture STO HA» was higher by 5.7, 9.5, 10.4% compared to piglets 1 – 3rd groups. Phagocytic activity of leukocytes pigs 2nd, 3rd, 4th groups 16 days old and has been above 18.3 (P < 0.05); 11.5; 16.8% (P < 0.05), respectively group 1, the 28-day age – 17.4 (P < 0.05); 12.9 (P < 0.05); 15.2%. Phagocytic activity of leukocytes in piglets 40th age of daily study groups was significantly (P < 0.05) higher respectively pigs in the control group. The difference between the performance of piglets second and the first group was 20.5%, the first and third – 16.0%, fourth and first – 18.6%. The intensity of phagocytosis (FI) in pigs 16-day age 2 nd, 3 rd, 4 th group was significantly higher at 16.5 (P <0.05), 12.9, 22.4% (P < 0.01), the 40th day age – to 23.6, 20.1, 21.3%, respectively (P < 0.05, P < 0.01) compared with the control group. The average daily gain of the piglets 4th group of from 31 th to 40 th day of life superior piglets of group 1 to 58.3%, and body weight in 40-day age – 15.5% (P < 0.01).
