β-胡萝卜素对妊娠母猪粪便、血清和乳汁中免疫球蛋白 A 浓度的影响
Effects of β-Carotene on Immunoglobulin A Concentration in Feces, Serum and Milk of Late-Pregnancy Sows
摘要
Abstract
This experiment was conducted to study the effects of dietaryβ-carotene on fecalβ-carotene content and immunoglobulin A ( IgA) concentration in feces, serum and milk of late-pregnancy sows.A total of 30 sows with the similar reproductive condition and the same parity were randomly divided into 3 groups with 10 pigs per group, which were fed for 60 days.The control group was fed a basal diet, and the half month group and one month group were fed the basal diet supplemented with 200 mg/kg β-carotene before expected date half month and one month, respectively.The fecal β-carotene concentration was tested by high performance liquid chromatography ( HPLC) , and enzyme-linked immunosorbent assay ( ELISA) was used to detect the concentration of IgA in feces, serum and milk.The results showed that the most of fecalβ-carotene contents in the half month group and one month group were significantly higher than those in control group ( P<0.05) .A week before delivery, the most of IgA concentrations in feces in half month group and one month group were higher than those in control group; but in one week after delivery, the most of IgA concentrations in feces in half month group and one month group were lower than those in control group.In serum and milk, the IgA concentrations in the half month group and one month group were higher than those in control group except ser-um IgA concentration in one month group ( P>0.05 ) .In summary, β-carotene can increase fecal β-carotene content and IgA concentration in serum and milk, and then enhance immune the function of late-pregnancy sows.关键词
