Embodiment Construction

[0011] Below with a preferred embodiment the method for changing meat goose female line breeding season of the present invention is described further in detail:

[0012] The whole method includes the transformation of the breeding geese house, the transformation of the sports field, the introduction of breeding goose seedlings, light control during the brooding / growing period, feed feeding during the brooding / growing period, start-up of breeding geese, forced moulting and management of laying geese in summer, among which:

[0013] The method of transforming the breeding house is as follows: 4 birds / m 2 Set up a semi-open breeding goose shed with a height of 60 centimeters above the ground. The bamboo net bed is divided into groups of 200 geese, and enough egg-laying nests are installed so that the breeding geese can rest and lay eggs at night. Carried out on a house net bed.

[0014] The method of sports field transformation is: press 2 / m 2 Build a hardened cement playground...

Abstract

The invention discloses a method for changing a meat goose female train mating season. The method includes the steps: importing goose parent goslings; controlling illumination in a gosling breeding / maturity breading period; and feeding feed in the breeding goslings / breading maturity period and enabling the goose parents to start egg-laying maturity, wherein time for importing the goose parent goslings is January-February months. A method for controlling the illumination in the gosling breeding / maturity breading period includes the steps: adopting 24-hour illumination in 1-7 ages in days, gradually transiting natural illumination after the goslings reach 7 ages in days, and implementing the illumination in the whole process for 15 hours per day after the goose parents reach 6 ages in month. A method for feeding feed in the goslings breeding / maturity breading period includes the steps: enabling the goslings to conduct free choice feeding in 0-12 ages in week, and adopting limiting breeding in 11-25 ages in week, gradually starting to increase the feed from 26 ages in week, and finally enabling the goslings to conduct free choice feeding. The method for changing the meat goose female train mating season further includes the steps: gradually decreasing feeding scale in January-February next year, and then stopping feeding for 2 days, next limiting feeding for about 2 weeks, pulling up main wing feathers and sub main wing feathers by using 1 week, and later gradually increasing the feed. The method enables the meat goose female train mating season to be changed to be April to December each year.

Description

technical field [0001] The invention relates to a method for changing the breeding season of the female line of meat geese, in particular to a method for changing the breeding season of the female line of Tianfu meat geese. Background technique [0002] The female line of Tianfu meat goose is a female parent strain with high reproduction rate cultivated by Sichuan Agricultural University and other units. The average number of eggs per year per goose is more than 85, which is much higher than the main meat goose breeds at home and abroad. It has been introduced into China for more than ten years. provinces and cities. Like most goose species, the female line of Tianfu meat goose also has the problem of seasonal reproduction, which is mainly manifested in the stop of laying eggs in summer (May-August, high temperature and strong light), resulting in a lack of goose seedlings in the market in summer. Seriously restricted the development of goose industry and commercial goose i...
