摘要 试验研究葛根水提物对断奶仔猪生长性能、免疫功能和血清生化指标的影响。选取120头35日龄体质健康、遗传背景相同的"杜长大"三元杂交仔猪(公、母各半)。采用单因素完全随机设计,将断奶仔猪随机分为4组,每组5个重复,每个重复6头仔猪。对照组仔猪饲喂基础日粮,低量组、中量组和高量组仔猪在基础日粮中分别添加500、1 000和2 000 mg/kg葛根水提物。试验期30 d。结果显示,与对照组相比,中量组仔猪平均日增重提高26.06%(P<0.05),中量组和高量组仔猪料重比分别降低19.42%和12.30%(P<0.05)。与对照组相比,中量组和高量组仔猪血清免疫球蛋白A (IgA)含量分别提高30.36%和34.82%(P<0.05),中量组和高量组仔猪血清免疫球蛋白M (IgM)含量分别提高21.68%和15.93%(P<0.05)。中量组仔猪血清总蛋白和球蛋白比对照组分别提高18.76%和17.74%(P<0.05)。研究表明,葛根水提物能够改善断奶仔猪的生长性能,增强免疫功能,改善血液生化指标,添加1 000 mg/kg葛根水提物作用效果较好。 The experiment studied the effect of Pueraria lobata water extract on growth performance, immune function and serum biochemical indexes of weaned piglets. The experiment selected 120 35-day-old ’Duroc×Landrace×Yorkshire’ ternary hybrid piglets with healthy physical fitness and the same genetic background(half male and half female). Using a single factor completely random design, weaned piglets were divided into four groups with five replicates in each group and six weaned piglets in each replicate. The piglets in control group were fed with basal diet,the piglets in low-dose group, medium-dose group and high-dose group were fed with basal diets adding Pueraria lobata water extract at concentrations of 500, 1 000 and 2 000 mg/kg. The trial period was 30 d. The results showed that compared with the control group, the average daily gain of piglets in medium-dose group was significantly increased by26.06%(P<0.05), the feed-to-weight ratio of the medium-dose group and high-dose group was significantly decreased by 19.42% and 12.30%(P<0.05). Compared with the control group, the serum IgA content in medium-dose group and high-dose group was significantly higher than those in control group by 30.36% and 34.82%(P<0.05), the serum IgM content in medium-dose group and high-dose group was significantly increased by 21.68% and 15.93%(P<0.05). The serum total protein and globulin in medium-dose group were significantly higher than that of control group by 18.76%and 17.74%(P<0.05). The experiment indicates that Pueraria lobata water extract can increase the growth performance of weaned piglets, enhance immune function and improve blood biochemical indicators. In the experiment, the effect of add 1 000 mg/kg Pueraria lobata water extract was better.
