摘要
以日粮蛋白质１５ ．５ ％ 、１４ ．５％ 、１３．５％ 等三组营养水平饲喂圈养马岗种鹅４０ ｄ，结果表明，以日粮蛋白质１５．５ ％ 组的产蛋量、产蛋率、平均蛋重、每枚蛋耗料量和经济效益为优。
Breeder geese fed the ration feed with three different contents of protein(15.5%,14.5% and 13.5%) for 40 days. The results showed that the group fed the feed with 15.5% protein had higher egg production, higher laying rate, higher average egg weight, and lower feed consumption as well as better economic benefits.
