为研究不同精料与苎麻配比对湘白鹅生长性能的影响,本试验选取健康、体重接近的7日龄湘白鹅225羽,分3阶段进行饲养试验,每阶段设5个处理,每处理5个重复,每个重复9只鹅. 试验A组为全精料饲喂的对照组;试验B~E组为添加不同比例苎麻的试验组. 试鹅2~4周龄阶段试验B~E组精料与饲用苎麻的饲喂比例分别为1:1、1:2、1:3和1:4,5~7周龄阶段试验B~E组精料与饲用苎麻的饲喂比例分别为1:2、1:3、1:4和1:5,8 ~ 10周龄为补饲育肥阶段,各组均只饲喂精料.结果表明:(1)试鹅2~4周龄和5~7周龄平均日增重和料重比均以对照组最优,且显著优于试验B~E组(P<0.05),而试验B~E组试鹅2~4周龄和5~7周龄平均日增重均随着苎麻添加量的增加而逐渐降低,料重比则随着苎麻添加量的增加而逐渐升高;补饲精料后,试验B~E组8~10周龄试鹅的平均日增重显著高于对照组(P<0.05),而料重比则显著低于对照组(P<0.05),但试验B、C、D和E组试鹅10周龄末重均显著低于对照组(P<0.05).(2)生产效益的结果显示除试验B组每只肉鹅盈利低于对照组外,其余各苎麻添加组盈利均比对照组高,且试验D组平均每只肉鹅盈利最高,为10.38元. 综上所述,本试验条件下,湘白鹅饲养的2~4周龄阶段日粮中按精料与苎麻1:3配比,5~7周龄阶段日粮中按精料与苎麻1:4配比饲喂, 再通过后期补饲精料,可获得较好的养殖效益.

In this research,the effect of different mix proprotion of concentrated feed with ramie on performance of Xiangbai goose was studied by three stages.A total of 225 healthy 7-day-old Xiangbai geese with the nearly same weight were selected and allocated randomly to 5 groups with 5 replicates of 9 each.The feed of control group (A) was all con-centrated feed,in week 2 ~ 4,concentrated feed to ramie ratio in group B to E was 1:1,1:2,1:3,1:4 respectively.And in week 5 ~ 7,concentrated feed to ramie ratio in group B to E was 1:2,1:3,1:4,1:5 respectively.In week 8 ~ 10,all group was feed with concentrate for fatling.The result showed that:(1)At week 2 ~4 and week 5 ~ 7,average daily gain(ADG) and feed/gain ratio (F/G)of group A was the best and significantly outperformed than those of group B ~ E (P < 0.05). During week 2 ~ 4 and week 5 ~ 7,ADG of group B,C,D,E decreased with the increase of ramie rate,and F/G of group B,C,D,E increased with the increase of ramie rate.After supplement of concentrated feed at week 8 ~ 10,ADG of group B,C,D,E were significantly higher than that of group A (P<0.05),and F/G were significantly lower than that of group A (P < 0.05).But the final weight of group B,C,D,E were significantly lower than that of group A at week 10 (P < 0.05). (2)Production benefit results showed that all group fed with ramie had higher benefit than the control group except group B.The highest profit was obtained from the group D by 10.38 Yuan per goose.All the analysis showed,by the mean of con-centrated fed with ramie ratio were 1:3 at week 2 ~ 4 and 1:4 at week 5 ~ 7,then fed with concentrated feed for fatling, better profit could be gained from Xiangbai goose.
