为了研究液体纳米维生素对猪生产性能和胴体品质的影响，选用80头20 kg左右的健康育肥猪并随机分为4组，每组4个重复，每个重复5头。对照组饲喂基础日粮，各试验组分别在基础日粮中添加固体维生素、普通液体维生素和液体纳米维生素，在体重达到100 kg左右时结束肥育并进行胴体品质测定。结果表明，维生素的添加对猪的日增重、料肉比、瘦肉率、眼肌面积和背膘厚均具有显著影响，且液体纳米维生素的效果显著优于固体维生素和普通液体维生素，普通液体维生素的使用效果优于固体维生素，但两者之间无显著差异。结果提示，液体纳米维生素较其他维生素可显著提高猪的生产性能并能显著改善胴体品质。

In order to study the effects of liquid nano-vitamin on the production performance and carcass quality of pigs, 80 healthy finishing pigs with the body weight of about 20 kg were selected and randomly divided into 4 groups, with 4 repetitions in each group (5 pigs in each repetition). In control group ,the pigs were fed with the basic diet. And the pigs in three experimental groups were fed with the basic diet supplemented with solid vitamin,ordinary liquid vitamin and liquid nano-vitamin. The experimental was ended when the weights of pigs were up to about 100 kg and the carcass quality indices of pigs were determined. The results showed that the addition of vitamin had significant effects on the daily weight gain, feed conversion ratio, carcass lean percentage, loin eye area and the back-fat thickness of pigs. And the effects of liquid nano-vitamin were significantly better than that of solid vitamin and ordinary liquid vitamin. The effects of ordinary liquid vitamin were better than that of solid vitamin, but there was no difference. Therefore, liquid nano-vitamin could significantly enhance the production performance and improve the carcass quality of pigs, compared with other kinds of vitamin.
