However, the vast majority of goose species in my country belong to the long-day sun breeding type, and the off-season breeding technology of long-day sun breeding goose species has not been reported. How to solve the off-season breeding of long-day sun breeding goose species has always been an unsolved problem in the goose industry. the puzzle

Embodiment 1
[0028] In this embodiment, the short-day breeding type Zhedong white goose is used as the male parent, and the long-day breeding type Yangzhou goose is used as the female parent.
[0029] 1. Breeding goose selection
[0030] In September, the healthy male seedlings of Zhedong White Goose, a type of goose that stays in short-day sunshine, were selected as the male parent goose, and the healthy female seedlings of Yangzhou Goose, a goose breed that was kept in long-day sunshine, were selected as the female parent goose.
[0031] 2. The off-season breeding light treatment procedure for the male Zhedong white goose:
[0032] Phase 1: Long light treatment.
[0033] Select the healthy goose seedlings of the year as the hybrid male parent. From late January to mid-March of the following year, the geese will be supplemented with light every day. After the breeding geese are driven into the goose house in the evening (nearly 18:00), the lights will be turned on until 24:00. Lights: T...
Embodiment 2
[0048] Control group 1. Egg production performance of Zhejiang white goose pure breeding under natural conditions
[0049] Zhedong white geese are very cuddly. Every time they lay a clutch of eggs, they have to incubate the eggs in the nest until the young chicks hatch and wait for the young chicks to grow for a period of time before re-entering the next egg-laying cycle. In the natural state, Zhejiang East White Goose begins to lay the first nest of eggs in mid-September every year, laying 7 to 9 eggs, and the second nest of eggs begins in mid-November. ~15 eggs, the third clutch of eggs is from mid-January to mid-February of the following year, and lays 8-10 eggs. After April, the libido of Zhejiang white geese males decreases, and the reproductive performance of female geese decreases rapidly. Nest eggs, about 2 to 3 pieces. The average annual egg production of Zhejiang White Goose is 29-37 pieces, and the fertilization rate is about 85%.

Abstract
The invention relates to the technical field of goose crossbred production, in particular to a method for efficiently producing high-quality meat type crossbred goose seedlings by enabling large-size low-reproductive-performance goose breed (a male parent) to crossbred with medium-and-small-sized high-reproductive-performance goose breed (a female parent), wherein the male parent is a short-day bred goose breed comprising Eastern Zhejiang white geese, Western Anhui geese, lion head geese, baisha crossbred goose, and the like. The female parent is a long-day bred goose breed comprising Yangzhou geese, Huoyan geese, Zi geese, Sichuan white geese, roman geese and the like. By carrying out long-short two-stage illumination regulation on the male parent and carrying out long-short-relatively-long three-stage illumination regulation on the female parent, so that the male parent and the female parent synchronously enter a reproductive stage, and therefore, the problems that the long-day bred goose breed and the short-day bred goose breed are difficult to breed as a result of staggered breeding seasons and are low in breeding rate are overcome, and therefore, normal breeding of the two goose breeds is realized, and crossbred production performance is improved; and illumination regulation is combined to carry out goose anti-season breeding production, so that an efficient production technical system of high-quality crossbred geese seedlings is established.
Description
technical field [0001] The invention relates to the technical field of goose hybrid production and off-season breeding production, especially the hybrid production of a large-sized, low-reproductive-performance goose species (male parent) and a small-to-medium-sized, high-reproductive-performance goose species (female parent) for efficient production. A method for high-quality and high-value meat goose fry. Background technique [0002] At present, the large-scale meat goose industry has a huge demand for high-quality goose breeds with fast growth, large size and good meat quality. However, the goose breeds with fast growth, large size and good meat quality in the market generally have low reproductive performance and cannot meet the market demand; and Commercial goose breeds with excellent reproductive performance are smaller in size and slower in growth, and are less popular in the market. It can be seen that traditional goose breeds and production methods can no longer m...
