转Bt基因糙米作为日粮原料对生长猪免疫功能的影响

Abstract

Abstract: The experiment aimed to study the effect of transgenic Bt brown rice as growing pig’s diet on immunity in growing pigs.30 Large White piglets were randomly allocated into 2 dietary treatments with 15 replicates per treatment.The control group diet consisted of basic diet and 70% non-transgenic Bt brown rice，and the test group consisted of basic diet and 70% transgenic Bt brown rice. This experiment lasted for 90 days.The results showed that effect of transgenic Bt brown rice on IgA，IgG，IgM contents and complements C3 and C4 levels in serum were no significant differences between the two groups （P＞0.05).Submicrostructure of liver and spleen of growing pigs in treatment group had no pathological changes according to tissue slice observation of two organs and also had no significant difference compared with the control group （P>0.05）.And there were no significant differences in immune organ index between the two groups （P＞0.05）.In conclusion，under this experimental condition，Bt brown rice as growing pig’s diet fed to growing pigs will not cause damage to immune organs and will not influence immune function.

Key words: Bt; immune function; pig
