免疫应激对不同品种仔猪免疫功能的影响
Effects of Immunological Stress on Immune Response in Different Breeds of Piglets
摘要
Abstract
[ Objective ] The research aimed to explore effects of an immunological stress on immune response in different breeds of piglets (Lulai pig, Laiwu pig and Yorkshire). [Method] All the 12 weaning pigs ( Lulai, Laiwu and Yorkshire) of(12.6±0.5) kg were used in a 2 × 3 factorial design. The main factors consisted of immunological challenge (LPS or saline) and breeds (Lulai pig, Laiwu pig and Yorkshire). On day one,6 piglets of each breed were injected with LPS at 200 μg/kg·BW or an equivalent amount of sterile saline, and injected swine plague vaccine at the same time. Blood sample were collected at 2、7 and 14 d post-injection to analysis the blood lymphocyte proliferation; The level of swine plague antibody of 1 d pro-injection and 7,14 d post-injection were test. [ Results ] On day 2 after injection, the lymphocyte transformation rate of piglets injected with LPS were significantly (P<0. 01 ) increased compared with piglets injected with saline. The lymphocyte transformation rate of Laiwu piglets were raised significant than Yorkshire piglets ( P < 0.05). Effects of immunological stress on the level of swine plague antibody had not significant difference in different breeds of piglets. [ Conclusion ] The results indicated that LPS can effectively stimulate cell immunity reaction in different breeds of piglets, and the immune response ability is different in various breeds of piglets.关键词
