Effects of quercetagetin on growth performance,diarrhea rate,and immunity of piglets

中文摘要英文摘要

试验探究了不同水平的槲皮万寿菊素对仔猪生长性能、腹泻率及免疫功能的影响,确定槲皮万寿菊素在断奶仔猪生产中应用的可行性.选取28日龄的"杜×长×大"仔猪96头,分成4组,每组3个重复,每个重复8头仔猪.各组仔猪饲粮中分别添加0(对照组)、200、400、800 mg/kg的槲皮万寿菊素.预试期1 w,正式试验期4w.结果显示,与对照组相比,400 mg/kg组的末重和平均日增重分别显著提高了6.39%、10.86%(P<0.05),料重比显著降低了8.68%(P<0.05);400 mg/kg组和800 mg/kg组的腹泻率极显著降低(P<0.01).与对照组相比,400 mg/kg组和800 mg/kg组仔猪血清D-乳酸含量极显著降低(P<0.01),肿瘤抑制因子-α(TNF-α)含量显著降低(P<0.05),免疫球蛋白A(IgA)含量显著提高(P<0.05);200 mg/kg组和400 mg/kg组血清白细胞介素-10(IL-10)含量显著提高(P<0.05);400 mg/kg组血清干扰素-γ(IFN-γ)含量显著提高(P<0.05),二胺氧化酶和内毒素水平显著降低(P<0.05).研究表明,槲皮万寿菊素可以提高仔猪的生长性能、免疫功能,降低腹泻率,最适添加水平为400 mg/kg.

This experiment was conducted to investigate the effects of different levels of quercetagetin on the growth performance,diarrhea rate,and immune function of piglets,and to determine the feasibility of application of quercetagetin in the production of weaned piglets.A total of 96'Duroc × Landrace × Yorkshire'piglets at 28 days of age were divided into four groups,with three replicates per group,each replicate consisting of eight piglets.Piglets in each group were fed diets supplemented with 0(control group),200,400,and 800 mg/kg quercetagetin,respectively.The preliminary trial lasted for one week,and the formal experiment lasted for four weeks.The results showed that compared with the control group,the final weight and average daily weight gain of the 400 mg/kg group were significantly increased by 6.39%and 10.86%,respectively(P<0.05),and the feed conversion ratio was significantly reduced by 8.68%(P<0.05).The diarrhea rate in the 400 mg/kg and 800 mg/kg groups was significantly reduced(P<0.01).Compared with the control group,the serum D-lactic acid content in the 400 mg/kg and 800 mg/kg groups was significantly reduced(P<0.01),the content of tumor necrosis factor-α(TNF-α)was significantly reduced(P<0.05),and the content of immunoglobulin A(IgA)was significantly increased(P<0.05).The serum interleukin-10(IL-10)content in the 200 mg/kg and 400 mg/kg groups was significantly increased(P<0.05),the content of interferon-y(IFN-y)in the 400 mg/kg group was significantly increased(P<0.05),and the levels of diamine oxidase and endotoxin were significantly reduced(P<0.05).The study indicates that quercetagetin can improve the growth performance,immune function and reduce the diarrhea rate of piglets.The quercetagetin optimal supplemental level is 400 mg/kg.
