不同饲养方式对鹅繁殖性能影响的比较研究

比较分析传统池塘养殖和新型戏水池养殖扬州鹅的产蛋性能和孵化性能,探讨两种饲养方式的优劣,以期证明新型戏水池养殖方式的可行性。研究结果表明,池塘养殖开产略迟（比戏水池养殖晚4d）,但高峰产蛋率达到了43.30%（比戏水池养殖高5%）,产蛋率〉35%维持的天数达到了59d,入舍母鹅产蛋数达到58.70个（比戏水池养殖入舍母鹅产蛋数56.24个高2.46个）,池塘养殖鹅群产蛋性能更好一些。受精率、受精蛋孵化率、健雏率,池塘养殖（88.97%、89.58%、97.90%）与戏水池养殖（87.92%、87.69%、98.05%）均无显著差异。综合考虑土地利用率、节水、养殖效率等因素,新型戏水池饲养方式可以在鹅养殖业中大面积推广使用。

Study on the effects of different rearing pattern on goose reproductive performance

The aim of this study is to analyze the effects of different rearing pattern on goose reproductive performance, and then analyze the feasibility of goose rearing in tiny pool.The performance of egg production and hatchability was detected and compared in Yangzhou geese which were reared in traditional pond and in tiny pool respectively. The result showed that age at the first egg of geese rearing in traditional pond is 4 days later than that rearing in tiny pool. The peak egg laying rate of goose rearing in traditional pond was43.30%, and was 5 percent higher than that in tiny pool. In goose rearing in pond, the time of egg laying rate more than 35% last 59 days, egg laying number was 58.70. And egg laying number was 56.24 in goose rearing in tiny pool. The egg production performance of goose rearing in traditional pond is better than that in tiny pool. No difference was found in fertilization rate of eggs, hatchability rate of fertile eggs and healthy gosling rate in goose of different rearing pattern. Fertilization rate of eggs, hatchability rate of fertile eggs and healthy gosling rate were 88.97%, 89.58% and 97.90% in goose rearing in traditional pond,and were 87.92%、87.69%、98.05% in goose rearing in tiny pool. Taking account of land-use ratio, water and culture benefit, the pattern of rearing goose in tiny pool has good promoted application prospect.
