摘　　要：为探究不同纤维源饲粮对5~10周龄四川白鹅生产性能和血清生化指标的影响,选择28日龄体重相近的四川白鹅120只,随机分为4组,每组3个重复,每个重复10只,分别饲喂黑麦草粉、花生秧粉、苜蓿草粉和燕麦草粉饲粮,持续42 d。结果显示:花生秧、苜蓿和燕麦组平均日增重显著高于黑麦组(P<0.05),其中苜蓿组日增重最大;燕麦组肝脏、肌胃、胰腺、脾脏和法氏囊指数均显著高于花生秧组(P<0.05);苜蓿组腺胃和法氏囊指数显著高于花生秧组(P<0.05);各组间十二指肠、空肠和回肠长度差异不显著(P>0.05),燕麦组盲肠长度显著高于其他三组(P<0.05);不同纤维源日粮对体斜长、胫长和骨盆宽影响显著(P<0.05);对平均日采食量、料重比和血清生化指标影响不显著(P>0.05),但总蛋白和高密度脂蛋白含量苜蓿组最高。结果表明,在5~10周龄的四川白鹅饲粮中添加苜蓿草或燕麦草可获得较好的生长性能、免疫力以及内脏器官发育。This experiment was designed to study the effects of different fiber source diet on the growth performance and serum biochemicalindexes of Sichuan White Geese aged 5 to 10 weeks.We randomly divided 120 white geese of similar body weight and 28 days of age into 4groups with 3 replicates in each group and10 geese per replicate.These geese were separately fed with perennial ryegrass,peanut vine,alfalfaand oat grass meal.The feeding experiment lasted for 42 days.The results showed that the average daily gain of the Sichuan White Geese fed with peanut vine,alfalfa and oat grass meal was significantly higher than that of the group fed with the perennial ryegrass meal(P<0.05),and the geese fed with alfalfa meal had the highest daily gain.The liver,muscle stomach,pancreas,spleen and bursa indexes of the group fed with oat grass meal were significantly higher than those of the groups fed with the peanut vine meal group(P<0.05).The glandular stom­ach and bursa indexes of the group fed with the alfalfa meal were significantly higher than those of the group fed with the peanut vine meal(P<0.05).However,there was no significant difference in the length of duodenum,jejunum and ileum indexes among all the groups(P>0.05).The length of cecum in the group fed with the oat grass meal was significantly higher than that in the other three groups(P<0.05).The effects of the diet of different fiber sources on the body length,length and pelvic width were significant(P<0.05).These effects on the average daily feed intake,feed-to-weight ratio and serum biochemical parameters were not significant(P>0.05),but the total protein and high-density lipoprotein content were the highest in the group fed with the alfalfa meal.The above results indicated that Sichuan White Geese 5 to 10 weeks of age obtain better growth performance,immunity and development of internal organs when fed with a diet supplemented withthe adding alfalfa or oat grass meal.
