摘要
Abstract
To study the effects of rice brain polysaccharide (RBS) on immunity in chicks, one hundred chicks were randomly divided into 4 groups. The chicks in experimental groups were dosed with rice bran polysaccharide at low, medium and high days from the age of 10 days. Peripheral T lymphocyte proliferation,titers of serum Ig were measured before chickens being dosed with RBS and on day 7,day 15 and day 21. All chickens of in every group were vaccinated with ND vaccine on day 14 and with AI vaccine on day 21. ND and AI antibody titers were measured on day 0 and on day 7,day 14 and day 21 after chickens vaccinated with ND vaccine and AI vaccine,respectively. The results showed 1) peripheral T lymphocyte proliferation in the three experimental groups were higher than those of the control on day 7,day 14 and day 21 after dosed with RBS groups; 2) the titers of Serum IgG in the three experimental groups were higher than that of the control group on day 7,day14 and day 21 after dosed RBS (P＜0. 05 or P＜0.01). There were no significant difference on the IgA titers between the low dosage group and control on day 14 after dosed RBS,but the IgA titers of the medium and high dosage groups were higher than those of the control group on day 14 and day 21 (P＜0. 05 or P＜0. 01). There was no significant difference in IgM titers between group Ⅳ and group Ⅰ on day 7,and between group Ⅲ and group Ⅰ on day 14. The IgM titers of the other experimental groups were higher than that ofthe control group(P＜0. 05 or P＜0. 01)on day 7 and on day 14,but there were no significant difference between them on day 21; 3) the ND and A1 antibody titers were higher after chickens being dosed with RBS, and the effect was positively correlated with RBS dosage.These data indicated that RBS could promote the immunity of chickens in many ways,such as peripheral T lymphocyte proliferation,serum titers of Ig and antibody.关键词
