本试验旨在研究黑麦草颗粒饲粮对扬州鹅生长性能、屠宰性能和血清生化指标的影响。试验选用1日龄扬州鹅300只，随机分成5组，每组3个重复，每个重复20只。各组饲粮黑麦草添加水平分别为0（对照组）、2％（Ⅰ组）、4％（Ⅱ组）、6％（Ⅲ组）和8％（Ⅳ组）。试验期为21 d。结果表明：1）7日龄时，Ⅱ、Ⅳ组平均日采食量显著低于对照组（P＜0．05），Ⅰ组平均日增重显著高于对照组（P＜0．05）；14日龄时，Ⅱ组平均日采食量显著低于对照组（P＜0．05），Ⅱ、Ⅲ组料重比显著低于对照组（ P＜0．05）；21日龄时，Ⅳ组平均日采食量显著高于对照组（ P＜0．05）。2）Ⅰ、Ⅱ、Ⅲ、Ⅳ组屠体重、半净膛重、全净膛重和腿肌重均高于对照组（ P＞0．05），各组胃pH无显著差异（ P＞0．05）。3）各组血清谷草转氨酶和碱性磷酸酶活性差异不显著（ P＞0．05）；Ⅰ、Ⅲ和Ⅳ组血清总蛋白含量显著高于对照组（ P＜0．05）；Ⅰ、Ⅱ组血清葡萄糖含量显著低于对照组（ P＜0．05）；Ⅰ、Ⅱ和Ⅳ组血清谷丙转氨酶活性显著低于对照组（ P＜0．05）。由此可见，黑麦草颗粒饲粮能够提高扬州鹅生长性能，改善屠宰性能和血清生化指标，黑麦草适宜添加水平为6％。

This experiment was conducted to study the effects of ryegrass pellet diet on growth performance, slaughter performance and serum biochemical indexes of Yangzhou geese.A total of 300 one-day-old Yangzhou geese were randomly divided into 5 groups with 3 replicates per group and 20 geese per replicate.Geese in the groups were fed the diets supplemented with 0 ( control group ) , 2% ( group Ⅰ) , 4% ( group Ⅱ) , 6%( group Ⅲ) and 8%( groupⅣ) ryegrass, respectively.The experiment lasted for 21 days.The results showed as follow:1) at 7 days of age, the average daily feed intake ( ADFI) in groups Ⅱ and Ⅳ was significantly lower than that in control group (P<0.05), the average daily gain in group Ⅰ was significantly higher than that in control group ( P<0.05); at 14 days of age, the ADFI in groupⅡwas significantly lower than that in control group ( P<0.05) , the ratio of feed to gain in groupsⅡandⅢwas significantly lower than that in con-trol group ( P<0.05); at 21 days of age, the ADFI in group Ⅳ was significantly higher than that in control group ( P<0.05) .2) The carcass weight, semi-eviscerated weight, eviscerated weight and leg muscle weight in groups Ⅰ, Ⅱ, Ⅲ and Ⅳ were higher than those in control group ( P>0.05 ) , there was no significant difference on stomachic pH among all groups ( P>0.05) .3) There was no significant difference on the activi-ties of glutamic oxalocetie transaminase and alkaline phosphatase in serum among all groups ( P>0.05);the se-rum total protein content in groups Ⅰ, Ⅲ and Ⅳ was significantly higher than that in control group ( P<0.05); the serum glucose content in groups Ⅰ and Ⅱ was significantly lower than that in control group ( P<0.05); the serum glutamic-pyruvic transaminase activity in groupsⅠ,Ⅱand Ⅳwas significantly lower than that in control group ( P<0.05).In conclusion, ryegrass pellet diet can improve the growth performance, slaughter performance and serum biochemical indexes of Yangzhou geese, and the optimal supplemental level of ryegrass is 6%.
