摘　　要：试验选取健康、体重约为63 kg的杜×长×大育肥猪32头,随机分为对照组和试验组,每组16头猪。用基础饲粮直接喂对照组猪,在基础饲粮中加胆碱(200 mg/kg)后,作为试验组饲粮,喂试验组猪,饲养试验期45 d。饲养试验结果表明:试验组猪平均日增重比对照组猪提高5.62%(P<0.05);试验组猪对饲料的转化率也比对照组高4.53%,但差异未达到显著的程度(P>0.05)。试验组猪血糖、血浆总蛋白、血浆尿素氮、血浆胆固醇含量和血浆GOT(谷草转氨酶)活性显著低于对照组猪(P<0.05);试验组血浆GPT(谷丙转氨酶)活性和血浆甘油三酯含量极显著低于对照组(P<0.01)。这些结果表明:给育肥猪补饲胆碱,可促进其生长,提高饲料转化率,增强生物膜稳定性,改善营养生化代谢。32 healthy,three-way crossbred（Duroc×Landrace×Yorkshire）finishing pigs weight-ing about 63 kg were selected and divided into 2 groups：the control and the experimental group,16 pigs in each group.The control group pigs were fed basal diet;the experimental group pigs were fed basal diet supplemented with 200 mg/kg choline. Feeding experimental period were 45 days. The feeding experimental results were as follows： Compared with the control group,ADG of the experimental group pigs increased by 5.62%（P〈0.05）;FCR of the experi-mental group increased by 4.53%（P〉0.05）;GLU,TP,UN and CHO concentrations and GOT activity in the experimental group pig plasma decreased significantly（P〈0.05）;GPT activity and TG concentration in the experimental group pig plasma decreased highly significantly（P〈0.01）.Based on the experimental results the conclusion was made：the supplementation of choline in finishing pig diet could promote the growth and feed utilization,increase bio-membrane stability,prove nutritionally biochemical metabolism.
