A method for regulating off-season breeding of northern breed geese

Abstract

The invention discloses a non-breeding-season reproduction regulation method for Northern-variety geese. The method includes the first step of illumination prolonging, wherein an illumination prolonging method is adopted to achieve transition from the all-season normal physiological development state of Northern-variety geese to the non-breeding-season physiological development state of geese so that the Northern-variety geese can lay eggs in the non-breeding season, illumination control measures varying in spring, summer, autumn and winter are adopted for illumination prolonging, and a time gradient method is adopted for illumination prolonging; the second step of feed control; the third step of forced moulting; the fourth step of supplementary feeding; the fifth step of light shielding; the sixth step of egg laying. By means of the non-breeding-season reproduction regulation method for Northern-variety geese, the egg laying peak of breeding geese can be regulated to be the period from the beginning of July to the end of October every year from the period from March to July every year, and balanced supply of Northern meat geese or goslings is achieved.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a control method for off-season breeding of northern breed geese. Background technique [0002] Due to the seasonality of the production and breeding activities of geese, in northern my country, the egg-laying period of geese is from March to July every year, and production stops after July, so that goose eggs, seedlings and commercial geese cannot be supplied all year round. The over-concentration of supply in the peak season and the lack of goose sources in the off-season severely restrict the development of the goose industry. [0003] Since the natural environmental conditions such as sunshine time and ambient temperature in northern China are quite different from those in the south, the existing technical solutions cannot meet the requirements for off-season reproductive performance of northern breeds of geese. How to effectively implement breeding geese for diff...

Problems solved by technology

[0002] Due to the seasonality of the production and breeding activities of geese, in northern my country, the egg-laying period of geese is from March to July every year, and production stops after July, so that goose eggs, seedlings and commercial geese cannot be supplied all year round. Excessive concentration of supply in peak season and lack of pan-goose sources in off-season severely restrict the development of goose industry

[0003] Since the natural environmental conditions such as sunshine time and ambient temperature in northern China are quite different from those in the south, the existing technical solutions cannot meet the requirements for off-season reproductive performance of northern breeds of geese. How to effectively implement breeding geese for different regions To control off-season breeding and reduce the cost of off-season production of breeding geese, it is necessary to explore practical methods according to local conditions
