Breeding method for high-quality and high-yield white goose

Abstract

The invention discloses a breeding method for a high-quality and high-yield white goose. The breeding method comprises the following steps of: (1) selecting an individual of a Chinese local goose species with high growth speed, clean and white feather, protruding head sarcoma, tidy and consistent shape and appearance and well-proportioned constitution as a second male parent of a synthetic line; (2) selecting an individual of a Chinese local goose species with clean and white feather, low female goose broodiness, superior egg producing performance, annual average yield of more than 70 eggs and good combining ability as a first female parent of the synthetic line; (3) selecting an individual of a Chinese local goose species with obvious sarcoma, clean and white feather of the whole body, mixed feather rate of less than 5 percent, annual average yield of more than 40 eggs and high early growth speed as a first male parent of the synthetic line; (4) hybridizing the male goose of the first male parent and the high egg productivity strain female goose in a matching way to form a second female parent of the synthetic line, and selecting the female goose with white feather, high egg productivity, high growth speed and high uniformity to reserve species; and (5) hybridizing the male goose of the second male parent and the female goose of the second female parent, and breeding the synthetic line with high meat productivity and high egg productivity.

Description

technical field [0001] The invention relates to a method for breeding goose, in particular to a method for cultivating high-quality and high-yield white goose. Background technique [0002] There are many goose breeds in China, 31 of which are included in the "China Poultry Breeds". Most of the goose breeds have the advantages of fast early growth and resistance to extensive feeding. They are typical grain-saving poultry. Goose breeding has constituted an important part of animal husbandry. . [0003] Because the reproductive performance of goose species is negatively correlated with the growth rate, the goose species with large body and fast growth rate produce less eggs, while the high-yield goose species are small in size and slow in growth rate. This has restricted the industrialization development of goose industry to a great extent. Wanxi white goose, Zhejiang east white goose, and Sichuan white goose are all national livestock and poultry protected species, and have...

AI Technical Summary

Problems solved by technology

Wanxi white goose, Zhejiang east white goose, and Sichuan white goose are all national livestock and poultry protected species, and have been included in the "National Livestock and Poultry Breeds Protection List", but in the actual production process, the three varieties have their own shortcomings However, it does not have many advantages such as large body size, fast growth rate and high egg production rate at the same time, which seriously restricts the breeding benefits.
