千里光超微粉对仔猪腹泻的防治效果及对血清IgG、IgA和IgM的影响

Effect of ultra-fine powder of Senecio scandens on diarrhea and serum IgG, IgA, IgM in piglet

为了探究千里光超微粉对仔猪腹泻的防治效果及对仔猪血清IgG、IgA和IgM的影响,选取40日龄杜×长×大三元杂交商品代瘦肉型仔猪90头,设6个处理,每个处理设3个重复,每个重复5头仔猪。处理1为对照,处理2、处理3、处理4、处理5分别在基础日粮中按质量比添加0.3%、0.6%、0.9%、1.2%的千里光超微粉,处理6在基础日粮中按质量比添加1.2%千里光普通粉,试验期为30 d。结果发现,在试验期3个阶段,添加不同量的千里光超微粉对仔猪腹泻频率、腹泻指数均有降低作用,以添加1.2%千里光超微粉效果最明显;千里光超微粉能显著提高仔猪血清IgG、IgA、IgM水平;一定量的千里光超微粉防治仔猪腹泻的效果优于千里光普通粉。

In order to evaluate the preventive and curative effect of ultra-fine powder of Senecio scandens （UFSS） on diarrhea and the influence of UFSS on serum IgG, IgA and IgM in piglet, 90 piglets（D×L×Y） with the age of 40 days were divided into 6 groups with 3 repetitions, each repetition had 5 piglets. Group 1 was control （no additive were added）. Piglets in group 2, group 3, group 4 and group 5 were fed with diets supplemented with 0.3%, 0.6%, 0.9%, 1.2% of UFSS, respectively, and piglets of group 6 were added 1.2% of ordinary powder of S.scandens in diet. The test lasted 30 d. The results showed that the diets added with certain quantities of UFSS could decrease diarrhea frequency and diarrhea index of piglets and the optimum dosage of UFSS was 1.2%, and the levels of IgG, IgA, IgM raised significantly, and the control effect of UFSS on diarrhea was better than that of ordinary powder of S. scandens in diet.
