Since the use of antibiotics in animal feed has become a critical concern worldwide due to severe threats to human health and environment, we are in need of finding alternatives to antibiotics in pig breeding, maintaining the health of pigs, and getting high-quality pork. As traditional Chinese herbs (TCH) are rich natural resources in China and show great benefits to human health we propose to transfer this abundant resource into animal production industry as additives.
Three groups of Chinese herbs (groups A, B, and C) were used as feed additives in the diet for pigs. In total 32 pigs were arranged in four groups (groups A, B, C, and control group, NC), fed in the same facility, eight pigs (one group) in each colony, free drinking, for 120 days. The feed:gain ratio (F/G), meat quality, total protein, and amino acid concentration of muscle were checked in the experiments.
After 120 days of feeding, the feed:gain ratio (F/G) of pigs in groups A, B, and C was decreased 17.56%, 9.31%, and 13.86% compared with NC treatment, respectively. The diets supplemented with Chinese herbs improved meat quality, increased loin eye area (especially group A and C showed significant difference, < .001), the total protein (increased ratio vs NC was A = 4.54%, B = 0.38% and C = 3.53%), amino acid concentration of muscle, increased the villus height:crypt depth ratio, and induced positive effects on serum biochemical parameters and immune function (serum TC and TG concentrations were significantly lower than those in the NC group, < .05.).
The use of Chinese herbal feed additives can reduce the cost of pig breeding and produce high-quality pock. The combination of these effects would contribute to better absorption ability of the intestinal tract and yield a better growth performance.
由于抗生素在动物饲料中的使用对人类健康和环境构成严重威胁，已成为全球关注的关键问题，因此我们需要在养猪业中寻找抗生素的替代品，以维持猪的健康并获得高质量的猪肉。由于传统中药是中国丰富的自然资源，且对人类健康有益，我们建议将这一丰富资源作为添加剂引入动物生产行业。
三组中药（A组、B组和C组）用作猪日粮的饲料添加剂。总共32头猪分为四组（A组、B组、C组和对照组，即NC组），在同一设施中饲养，每个圈舍8头猪（一组），自由饮水，为期120天。实验中检测了饲料转化率（F/G）、肉质、肌肉总蛋白和氨基酸浓度。
饲喂120天后，A组、B组和C组猪的饲料转化率（F/G）与NC组相比分别降低了17.56%、9.31%和13.86%。添加中药的日粮改善了肉质，增加了眼肌面积（尤其是A组和C组差异显著，P<0.001），总蛋白（与NC组相比增加的比例为A组=4.54%，B组=0.38%，C组=3.53%），肌肉氨基酸浓度，增加了绒毛高度与隐窝深度的比值，并对血清生化参数和免疫功能产生了积极影响（血清总胆固醇和甘油三酯浓度显著低于NC组，P<0.05）。
使用中药饲料添加剂可以降低养猪成本并生产出高质量的猪肉。这些效果的综合作用将有助于提高肠道的吸收能力并产生更好的生长性能。
