Problems solved by technology

[0004] Sansui duck is of good quality but messy. The current production level is inconsistent and cannot meet market demand.
There is no application for the improvement of poultry strains, let alone the application for the improvement of Sansui duck strains

Embodiment

[0028] In October 2011, Guizhou Qianlishan Ecological Food Co., Ltd. established two hybrid mating combinations for strain breeding. A total of 200 Chaohu male ducks were introduced as male parents, and a total of 3,000 female ducks were hybridized with Sansui Duck at a ratio of 1:15. , to provide 620,000 first-generation hybrid ducklings annually.

[0029] Breeding male and female ducks: In the young stage, male and female ducks are raised in groups, mainly for grazing, and they eat wild feed, exercise more, and do more activities; male ducks that have begun to mature but have not yet reached the mating period are stocked in dry land, and less Go into the water to reduce male ducks’ habit of playing with each other; 20 days before mating, put them in the group of female ducks. In addition to providing necessary nutrients with high or low egg rate, more vitamins and green feed should be fed, especially vitamin E should be appropriately increased to improve the fertilization ra...

Abstract

The invention discloses a method for modifying hybrid matching strains of Sansui duck. The method includes firstly, selecting breeding female and male ducks; secondly, feeding the breeding female and male ducks; thirdly, establishing and managing a feeding area; fourthly, hybridizing; and fifthly, feeding in the laying stage. By optimized purification and hybridization, genetic stability of fine characters of the Sansui duck such as meat quality and the like is improved, and growth speed and feed reward of the Sansui duck are increased. The strains are established and are propagated, and accordingly the related contradiction between low growth speed and meat quality is overcome. Hybridization experiments are performed, hybrid vigor of the Sansui duck is taken advantage, the strains are selected and bred selectively, and breeding value of the Sansui duck is increased. By strain selection and selective breeding, feeding management condition improvement and the like, fertilizing rate andhatching rate are increased, breeding egg quality is improved while reproduction rate is increased, and disease resistance of Sansui duck is improved. The method is applicable to strain modification for Sansui duck.

Description

technical field [0001] The invention relates to a method for improving varieties of poultry, and more specifically, to a method for improving strains of three-eared ducks. Background technique [0002] Sansui Duck ( sansui duck ) belongs to small egg-type local breeds, and is one of the four major local ducks in China. It was included in the "China Poultry Breeds" in 1989, and was included in the "Guizhou Livestock and Poultry Breeds" in 1993. In 2003, it was included in the "China Poultry Breeds" Atlas of Landrace Species Resources. Sansui duck is centered in Sansui County, Guizhou Province, and is distributed in more than ten counties such as Zhenyuan, Cengong, Tianzhu, Taijiang, and Jianhe. In recent years, the breeding of Sansui ducks has covered more than 20 counties and cities, and the breeding volume of ducks in the central production area has remained at more than 2 to 3 million. Light and small, in the shape of a boat, with tight and shiny feathers, it has stron...
