摘　　要：本研究包括2个试验,试验1旨在评定大豆磷脂油的有效能值;试验2旨在研究大豆磷脂油对断奶仔猪生长性能、血清脂质代谢及直肠微生物数量的影响。试验1(代谢试验):选用16头平均体重(27.54±1.20)kg的"杜×长×大"去势公猪,随机分为2个组,每个组8个重复,每个重复1头猪,分别饲喂基础饲粮和4%大豆磷脂油替换基础饲粮的试验饲粮,预试期5d,正试期4 d。试验2(饲养试验):选用54头23日龄断奶、初始体重(6.50±0.48)kg"杜×长×大"仔猪,按体重相近原则随机分为3个组,每个组6个重复,每个重复3头猪,分别饲喂基础饲粮(含2%大豆油,对照组)、1.0%磷脂油饲粮(大豆磷脂油等量替代基础饲粮中50%大豆油,即含1.0%大豆油+1.0%磷脂油)和1.5%磷脂油饲粮(大豆磷脂油等能替代基础饲粮中50%大豆油,即含1.0%大豆油+1.5%磷脂油),试验期35 d。代谢试验结果表明:大豆磷脂油的表观消化能为31.32 MJ/kg,表观代谢能为30.07 MJ/kg。饲养试验结果表明,与对照组相比:1)第15~35天,1.0%、1.5%磷脂油饲粮组仔猪平均日采食量(ADFI)分别提高了6.23%和3.13%(P>0.05),平均日增重(ADG)分别提高了6.66%和5.28%(P>0.05);第1~35天,1.0%磷脂油饲粮组仔猪ADFI和ADG分别提高了5.34%和5.64%(P>0.05)。2)1.0%磷脂油饲粮组仔猪腹泻率和腹泻指数分别降低了5.81%和13.41%(P>0.05)。3)1.0%磷脂油饲粮组仔猪血清甘油三酯和游离脂肪酸的含量分别降低了10.91%和12.80%(P>0.05);1.5%磷脂油饲粮组血清甘油三酯、总胆固醇和高密度脂蛋白胆固醇含量分别降低了7.27%、5.33%和10.53%(P>0.05)。4)第15天,1.0%和1.5%磷脂油饲粮组仔猪直肠粪便大肠杆菌数量分别降低了4.88%和4.12%(P>0.05);第36天,1.0%磷脂油饲粮组仔猪直肠粪便大肠杆菌数量降低了4.88%(P>0.05)。综上可见,大豆磷脂油的表观消化能为31.32 MJ/kg,表观代谢能为30.07 MJ/kg;饲粮添加1.0%大豆磷脂油等量替代基础饲粮中的大豆油,可一定�The study contained two experiments to evaluate the effective energy value of soybean-lecithin oil and to determine the effects of soybean-lecithin oil on growth performance,serum lipid metabolism and rectal microflora number of weaned piglets.Experiment 1（ metabolism experiment）： sixteen emasculated pigs（ Duroc × Landrance × Yorkshire） with an average body weight of（27.54 ± 1.20） kg were randomly divided into2 groups with 8 replicates in each group and 1 pig in each replicate.The pigs were fed basal diet and experiment diet which used 4 % soybean-lecithin oil replaced basal diet,respectively.The trial lasted for 5 days for adaptation,and 4 days for sampling.Experiment 2（ feeding experiment）： fifty four weaned piglets（ Duroc ×Landrance × Yorkshire,weaned at 23 days of age） with initial body weight of（ 6.50 ± 0.48） kg were randomly divided into 3 groups with 6 replicates per group and 3 pigs per replicate.Pigs were fed the basal diet（2% soybean oil,control group）,1.0% soybean-lecithin oil diet（50% soybean oil in basal diet was substituted by the same amount of soybean-lecithin oil,1.0 % soybean oil ＋ 1.0 % soybean-lecithin oil） and 1.5 %soybean-lecithin oil diet（ 50 % digestible energy provided by soybean oil in basal diet was substituted by the same digestible energy of soybean-lecithin oil,1.0 % soybean oil ＋ 1.5 % soybean-lecithin oil）.The whole trial lasted for 35 days.The metabolism experiment results showed that soybean-lecithin oil contained 31.32 MJ/kg apparent digestible energy and 30.07 MJ/kg apparent metabolizable energy.The feeding experiment results showed as follows,compared with the control group： 1） on day 15 to 35,the average daily feed intake（ADFI） of piglets in 1.0% and 1.5% soybean-lecithin oil group was increased by 6.23% and 3.13%（P〉0.05）,and the average daily gain（ ADG） was increased by 6.66 % and 5.28 %（ P〉0.05）.Furthermore,on day 1 to 35,the ADFI and ADG of piglets in 1.0 % soybean-lecithin oil diet group were improv
