草料混合养鹅与精料养鹅效益比较

[目的]探讨优质牧草饲养鹅的可行性,为广东发展种草养鹅提供依据。[方法]以矮象草(组Ⅰ)和从美国引进的杂交臂形草Ⅰ(组Ⅱ)、Ⅱ(组Ⅲ)进行牧草混合精料养鹅试验,组Ⅳ用纯精饲料,测定各组肉鹅的日增重。[结果]组Ⅰ、组Ⅱ、组Ⅲ、组Ⅳ的平均日增重分别为39.48、47.104、3.874、4.97 g/只。肉鹅饲养早期各处理的日增重均随天数增加而增加,第2阶段(36~45日龄)最高,第4阶段(61~80日龄)最低,下降最慢的是组Ⅱ。组Ⅱ的料肉比一直平稳降低,说明其对肉鹅的增重效果较佳。采用牧草混合精料饲养肉鹅节约了精料,降低了养殖成本,改善了肉鹅的屠体品质,烹调出来的肉食品味道香。[结论]杂交臂形草Ⅰ混合精料养殖肉鹅的效益较好。

Benefit Comparison of Mixed Forage Fodder and Concentrate in Goose-raising

[Objective] The aim was to discuss the feasibility of goose-raising with high quality forage and provide the basis for grass planting for goose-raising in Guangdong.[Method] The forage mixed with concentrate for goose-raising was tested with the P.purueumer(Group I) and hybrid Brachiaria decumbens Ⅰ(GroupⅡ) and Ⅱ(Group Ⅲ),which were introduced from America and the pure concentrate was used in Group Ⅳ.The daily gain of meat goose in each group was determined. [Result] The average daily gain of Group Ⅰ,Group Ⅱ,Group Ⅲ and Group Ⅳ were 39.48,47.10,43.87,44.97 gram per one resp.The daily gain of each treatment for meat geese at feeding early stage was all raised with the increase of number of days,that of the 2nd stage(36-45 day old) was the highest,and that of the 4th stage(61-80 day old) the lowest,and that in Group Ⅱ was slowest in the falling.The feed conversion ratio of Group Ⅱ was always decreased constantly, indicating it had a better effect of on weight gain on of meat geese.The concentrate was saved by adopting forage mixed concentrate for goose-raising,culturing cost reduced,carcass quality of meat geese improved,and meat food was delicious after cooking.[Conclusion] The benefit of hybrid B.decumbens Ⅰ mixed with concentrate was comparatively better in culturing the meat goose.
