摘　　要：为了研究不同料型对90~210日龄乌苏里貉生产性能和经济效益的影响,试验随机选取90日龄乌苏里貉80只公母各半,平均分为TG1~TG3组和CG组,每组20只(公母各半),分别饲喂颗粒料1(TG1)组、颗粒料2(TG2)组、干粉料(TG3)组和鲜饲料(CG)组,以CG组为对照连续饲喂120 d,测定生产性能和经济效益。结果表明:与CG组相比,各试验组的210日龄公貉和母貉体重均差异不显著(P>0.05);各组公貉和母貉体长均增加,TG2组差异显著(P<0.05);TG2组母貉针毛长显著缩短(P<0.05),各组公貉和TG1组、TG3组母貉针毛长差异不显著(P>0.05),各组公貉和母貉绒毛长差异不显著(P>0.05)。90~150日龄TG2组公貉料重比显著升高(P<0.05),各试验组母貉料重比显著升高(P<0.05);150~210日龄TG1组和TG3组母貉料重比显著降低(P<0.05),各试验组公貉料重比差异不显著(P>0.05)。TG1组、TG2组和TG3组每只貉分别增加利润18.74%、12.24%和21.04%。说明与饲喂鲜饲料相比,饲喂颗粒料和干粉料对乌苏里貉取皮前体重无显著影响,可以增加体长,90~150日龄料重比增加,151~210日龄料重比降低,综合养殖效益提高。To study the effects of different feed types on growth performance and economic benefit of 90-210-day-old Ussuri raccoon dogs, eighty 90-day-old raccoon dogs(half male and half female) were randomly divided into TG1-TG3 groups and control group(CG), with twenty raccoon dogs in each group(half male and half female). The raccoon dogs were fed pellet diet 1(TG1), pellet diet 2(TG2), powder diet(TG3) and fresh feed(CG), respectively. The experiment lasted for 120 days. Production performance and economic benefits were evaluated. The results showed that compared with CG, there was no significant difference in body weight of 210-day-old male and female raccoon dogs(P>0.05), body length of male and female raccoon dogs increased in all groups, but the difference was significant in TG2 group(P<0.05), meanwhile, the needle hair length of female raccoon dogs in TG2 group was significantly shortened(P<0.05). Compared with the control group, there was no significant difference in needle hair length of male raccoon dogs in each group and of female raccoon dogs in the TG1 group and TG3 group(P>0.05). There was no significant difference in villi length between male and female raccoon dogs(P>0.05) in each group. Compared with the control group, feed/gain of male raccoon dogs aged 90 to 150 days in TG2 group was significantly increased(P<0.05);that of female raccoon dogs in all experimental groups was significantly increased(P<0.05), and that of female raccoon dogs aged 151 to 210 days in the TG1 and TG3 groups was significantly decreased(P<0.05), but there was no significant difference in feed/gain of male raccoon dogs in experimental groups(P>0.05). The economic efficiency per raccoon dog increased by 18.74% and 12.24% and 21.04% in the TG1 and TG2 and TG3 groups, respectively. The results indicated that compared with fresh feed, feeding pellet diet and powder diet had no significant effect on the body weight before getting racoon fur, but could increase body length, and the feed/gain ratio increased from 90 to 150 days, but dec
