中草药添加剂对猪育肥性能和肉质的影响

为了探索在育肥猪日粮中添加中草药对育肥和肉质性状的影响,选择杜长大三元杂交仔猪72头,分为4组,每组18头,公母各半,组内设3个重复、每个重复6头试验猪。试验1组和2组分别在基础日粮中添加不同成分的复方中草药添加剂,添加比例为2.00%;试验3组在日粮中添加100 mg/kg土霉素;试验4组是对照组,饲喂基础日粮。饲养100 d,测定试验猪生长育肥性状和肉质性状。结果表明:与抗生素组相比,添加2种中草药添加剂均可以显著提高日增重、肌肉大理石纹评分和眼肌面积(P<0.05),并极显著降低失水率(P<0.01),增加肌肉粗脂肪含量(P<0.01)。可见,饲料中添加中草药添加剂可以有效提高育肥性能,改善猪肉品质。

Effect of Chinese herb feed additives on fattening performance and meat quality of swine

This experiment was conducted to investigate the effect of Chinese herb additives on fattening performance and meat quality of pigs.Seventy two crossbred piglets(Duroc×Landrace×Yorkshire) were divided into four groups with three replicate for each group.Groups1 and 2 were fed with two different compound Chinese herb additives,respectively,and group 3 was fed with antibiotic additives(oxytetracycline).Control group were fed with basal diet.The percentage of the additive was 2.00%.Fattening performances and meat quality traits were recorded after slaughter.Compared to antibiotic group,Chinese herb feed additives significantly increased daily gain,marbling rating,loin eye area(P<0.05),and crude fat content(P<0.01),and decreased water loss rate.In conclusion,the diet added with Chinese herb additives can improve fattening performance and meat quality of pigs effectively.
