鹅反季节繁殖的研究进展

Research progress of out-of-season reproduction in geese

鹅的繁殖具有明显季节性、产蛋周期短、就巢性强等特点。不同品种鹅的繁殖季节性表现差别较大。在中国,多数鹅种在每年的9月到翌年5月间产蛋。为提高种鹅和雏鹅留种的养殖效益,我国多个地区开展了种鹅反季节繁殖技术,其中通过营养调控、强制换羽和调节光照时间等技术措施可实现鹅在反季节繁殖期间产蛋,进一步提高了鹅的繁殖性能、受精率及经济效益,同时也缓解了反季节期间市场鹅苗供应不足的问题。文章主要阐述了鹅在反季节繁殖特性方面的研究进展,为日后进一步完善我国鹅饲养管理技术、提高鹅反季节繁殖性能提供参考。

The reproduction of geese is characterized by obvious seasonality,short laying period and strong nesting.Different breeds also exhibit large variations in breeding seasonalities.To improve the breeding benefits of breeding geese and goslings reserve,such out-of-season breeding techniques as artificial nutrition regulation,forced molting and adjust light time have been practiced in many regions of China,showing the laying during out-of-season breeding,which further improved the reproductive performance,fertility rate and economic benefits of rearing geese,and also alleviated the situation of insufficient supply of goose seedlings in the market during the out-of-season period.This paper mainly expounds the research progress of out-of-season reproduction characteristies in geese,with an intention of providing a reference for further developing breeding management technology and improving the out-of-season reproduction performance in geese in the future.
