目的 验证不同剂量大柴胡汤加味联合亚硒酸钠VE粉对猪黄膘病的治疗效果，为该病的中兽药临床防治提供参考。 方法 试验对象为广西壮族自治区崇左市辖县某生猪养殖场自然感染黄膘病的患猪（110日龄左右，（47.1±1.21） kg）20头，随机分为4个治疗组（试验A组、试验B组、试验C组和试验D组），每组5头患猪，试验A、B、C组分别给予低中高剂量（40、60、80 g/d）大柴胡汤加味散和100 g亚硒酸钠VE粉，试验D组只给患猪喂服100 g亚硒酸钠VE粉，10 d为1个治疗周期，试验期15 d，对猪黄膘病的治疗效果及预后情况进行评价。 结果 给药第5天，4组患猪治愈率相同，均为60%；给药第10天，试验C组患猪治愈率最高，为100%；停药后第5天，4组患猪均治愈率均为100%。与试验D组相比，试验B组和试验C组患猪的平均日增质量分别显著提高13.22%和16.68%，平均日采食量分别显著提高3.43%、4.39%。试验C组患猪的料肉比较试验A组和试验D组显著降低，分别降低了0.31、0.53。 结论 大柴胡汤加味的剂量为80 g/d时联合100 g亚硒酸钠VE粉治疗猪黄膘病效果最佳，且可以改善患猪的预后生产性能。

Objectives The effects of modified Dachaihu decoction combined with sodium selenite VE powder on treating the pig yellow fat disease were verified to provide reference for the prevention and treatment of this disease in clinics with traditional Chinese veterinary drugs. Methods 20 pigs aged 110 days with (47.1 ± 1.21) kg and naturally infected with yellow fat disease in a pig farm in Chongzuo City, Guangxi Zhuang Autonomous Region were selected and randomly divided into four treatment groups including the experimental group A, the experimental group B, the experimental group C, and the experimental group D, with 5 pigs in each group. The experimental group A, B, and C was given the low (40 g/d), medium(60 g/d), and high dose (80 g/d) of Dachaihu decoction combined with 100 g sodium selenite VE powder,. The experimental group D was only fed with 100 g sodium selenite VE powder, with a treatment period of 10 days and a trial period of 15 days. The effects on treating the pig yellow fat disease and prognosis were evaluated. Results The rate of recovery in the four groups was the same on the fifth day after administration, all at 60%. The rate of recovery in the experimental group C was the highest on the 10th day after administration, reaching 100%. The rate of recovery in the four groups on the fifth day after drug withdrawal was 100%. The average daily weight gain and the average daily feed intake of pigs in the experimental group B and C significantly increased by 13.22% and 16.68%, 3.43% and 4.39% compared with that in the experimental group D. The feed-to-gain ratio of pigs in the experimental group C was significantly lower than that in the experimental groups A and D, with reductions of 0.31 and 0.53, respectively. Conclusions When the dose of modified Dachaihu decoction was 80 g/d combined with 100 g sodium selenite VE powder, the best effect was achieved in treating the pig yellow fat disease, and it can improve the prognosis and production performance of pigs infected with yellow fat disease.
