摘要
研究了饲粮中添加１００ｍｇ／ｋｇ镧对生长猪生长、消化和胴体组成的影响，结果表明：添加镧使日增重、采食量分别提高了１３．２６％（ｐ＜０．０５）和５．４３％（ｐ＜０．０５）；料重比下降了６．５３％（ｐ＜０．０５）；饲料干物质、粗蛋白、粗脂肪的消化率分别提高了７．８２％（ｐ＜０．０５），５．３２％（ｐ＜０．０５）和５．４１％（ｐ＜０．０５）；肝脏和背最长肌中粗脂肪的含量分别下降了１４．２９％（ｐ＜０．０５）和２０．７１％（ｐ＜０．０５）；肝脏粗灰分含量提高了１１．８４％（ｐ＜０．０５）；但对生长猪的胴体组成。
This trial was conducted to determine the effects of Lanthanum(La) on growth, digestion,carcass composition of growing pigsThe results showed that:ADG and ADFI were increased by 1326% (p<005) and 543% (p<005), F/G was decreased by 653% (p<005), apparent digestibility of DM,CP and EE were enhanced by 782% (p<005), 532%(p<005) and 1541%(p<005) respectively, and that supplemental La decreased the content of EE in liver and LD by 1429% (p<005) and 2071%(p<005) respectively and the content of CA in liver by 1184% (p<005),while no effect was found on carcass composition, meat quality and weight of organs with the supplementation of La,
