马岗鹅反季节繁殖控制技术研究

Reproduction control technique of Magang goose in non-breeding season

鹅具有明显的季节性繁殖特征,繁殖活动的季节性导致鹅苗及肉鹅供应呈现明显的季节性变化,市场价格波动较大。通过对马岗鹅人为的控光、控料和强制换羽等综合技术措施开展反季节繁殖。试验结果表明:反季节繁殖产蛋量、受精率和孵化率低于自然繁殖,但反季节繁殖鹅苗市场价格提高42.9%、种鹅年产雏鹅收入提高22.4%、利润提高34.3%,实现了鹅苗及肉鹅全年均衡生产,解决了自然繁殖高峰期鹅苗供大于求导致价格下跌的问题,经济效益高于自然繁殖季节。

Goose is seasonal breeding animal, the goslings and adult geese supply show seasonal changes, so that the sale price of the geese is fluctuating. In this paper, control illumination time, feed quantity and forced molting on the Magang geese were carried out in non-breeding season. The results show that the number of egg laying, fertilization rate and hatching rate are lower than the natural reproduction, but the goslings sales prices increased by 42.9%, the annual income of goose is increased by 22.4%, and the profit for the year increased by 34.3%,also the goslings and goose can balance production throughout the year. The problems such as goslings’ seedling oversupply making price declining in natural breeding season are solved, therefore the farm can obtain better economic benefits based on the reproductive control technology in non-breeding season.
