摘　　要：研究旨在评定发酵花生粕(FPM)的营养价值并研究其对断奶仔猪生长性能影响。试验分为3个部分。试验1:将12头初重为(10.0±2.0) kg的“杜×长×大”三元去势公猪随机分为2组,分别饲喂基础饲粮和FPM饲粮,每组6个重复,每个重复1头猪。利用全收粪法测定两种饲粮的有效能值,并通过套算法计算FPM的猪消化能与代谢能。试验2:选取12头回肠末端安装T型瘘管的初重为(15.0±2.0) kg的“杜×长×大”三元去势公猪随机分为2组,分别饲喂无氮饲粮和以30%FPM为唯一氮源的半纯合饲粮,每组6个重复,每个重复1头猪。试验期7 d,于最后2 d收集回肠末端食糜以测定FPM的表观回肠消化率(AID)和标准回肠消化率(SID)。试验3:将50头初重为(8.0±1.0) kg的断奶仔猪(公、母各半)随机分为5组,每组10个重复,每个重复1头猪。对照组饲喂玉米-豆粕型基础饲粮,试验组分别饲喂添加2%、4%、6%、8%的FPM试验饲粮,试验期21 d。结果显示:FPM (风干基础)的消化能和代谢能分别为15.17和13.83 MJ/kg,其赖氨酸、蛋氨酸、苏氨酸、色氨酸的SID分别为85.85%、92.44%、87.80%、84.09%。与对照组相比,饲粮中添加FPM对断奶仔猪的平均日采食量和腹泻率无显著影响(P>0.05);添加2%~8%FPM可显著增加平均日增重(P<0.05),降低料重比(P<0.05)。研究表明,FPM的有效能值和氨基酸利用率较高,在断奶仔猪饲粮中添加2%~8%FPM可降低仔猪料重比,其中6%添加比例的饲喂效果较好。The purpose of the study was to evaluate the nutritional value of fermented peanut meal(FPM)and its effect on the growth performance of weaned piglets.The experiment was divided into three parts.Experiment 1:Twelve'Duroc×Landrace×Yorkshire'ternary castrated boars with initial weight of(10.0±2.0)kg were randomly divided into two groups,which were fed with basal diet and FPM diet respectively,with six replicates in each group and one pig in each replicate.The available energy values of two kinds of diets were measured by total fecal collection method,and the digestive energy and metabolizable energy of pigs were calculated by nested algorithm.Experiment 2:Twelve'Duroc×Landrace×Yorkshire'ternary castrated boars with an initial weight of(15.0±2.0)kg with T-shaped fistula installed at the end of ileum were randomly divided into two groups,which were fed with nitrogen-free diet and semi-homozygous diet with 30%FPM as the only nitrogen source,with six replicates in each group and one pig in each replicate.The experiment lasted for seven days,The apparent ileal digestibility(AID)and standard ileal digestibility(SID)of FPM were measured by collecting terminal ileal chyme on the last two days.Experiment 3:50 weaned piglets with an initial weight of(8.0±1.0)kg were randomly divided into five groups with 10 replicates in each group,half in male and half female,with one pig in each replicate.The control group was fed with corn-soybean meal basal diet,and the experimental group was fed with 2%,4%,6%,and 8%FPM experimental diets for 21 days.The results showed that the digestive energy and metabolizable energy of FPM were 15.17 and 13.83 MJ/kg, respectively, and the SIDof lysine, methionine, threonine and tryptophan were 85.85%, 92.44%, 87.80%, and 84.09% respectively. Compared withthe control group, the dietary FPM had no significant effect on the average daily feed intake and diarrhea rate of weanedpiglets (P>0.05). Addition of 2%~8% FPM significantly increased average daily gain (P<0.05) and decreased feed-toweightrati
