Embodiment 1

[0034] In the disinfection bactericidal farm, the male duck in the F11 line is used as a parent. It is used as a mother's duck in the F12 Series to obtain three generations of hybrid group F21, and then the individual blocks of the F21 is explicitly advantageous. 2 Generation, testing and measurement of eggs, laying eggs and feed rate of eggs in individual microves, resulting in results: 194 eggs in the year, annual output of 16.46 ± 0.28 KG, annual estate egg feed consumption is 68.94 ± 8kg, with good annual egg volume, annual output egg rate and annual output and lower annual egg feed consumption.

Embodiment 2

[0036] In the sterilized sterilization farm, the male duck in the F11 line is used as a parent. It is used as a mother's duck in the F12 Series to obtain three generations of hybrid group F21 lines, and then the F21 line has a dominant advantage to breed the third Generation, test and measurement of eggs, layout of egg ducks, and egg yield feed consumption, resulting in the results of 225 eggs in the year, 18.64 ± 0.51 ovary KG, annual egg period feed consumption was 65.56 ± 10kg, compared to Example 1, which has good annual egg quantity, annual output egg rate and annual output of egg yield and lower annual egg feed consumption.

Embodiment 3

[0038]In the disinfection bactericidal farm, the male duck in the F11 line is used as a parent. It is used as a parent duck in the F12 Series to make three generations of hybrid group F21 lines, and then the F21 line has a dominant advantage to breed the fourth Generation, testing and measurement of eggs, laying eggs and feed rate of eggs in eggs, resulting in results: 253 eggs in the annual egg weight of 20.54 ± 0.81 Kg, annual egg period is 63.32 ± 15kg, compared to Example 2, which has high annual egg quantity, annual egg rate and annual output of eggs and lower annual egg feed consumption.

Abstract

The invention discloses a method for breeding purebred shelducks, which comprises the steps of establishing a line of purebred mountain shelducks with small body size and high egg production from the female line, and establishing a line of purebred Jinding ducks with high egg production rate from the male line, And cross it to obtain a first-generation hybrid population, as the F1 line. In the present invention, purebred mountain shelducks with small body and high egg production, purebred Jinding ducks with high egg production rate, purebred Putian black ducks with heavy egg weight and purebred Fujian ducks with low feed consumption during laying period The excellent genes of Nongbai duck are hybridized and fused to obtain a purebred shelduck with excellent comprehensive performance. According to the characteristics of the mountain shelduck, Putian black duck, Jinding duck, and Minnong white duck, the present invention undergoes hybridization and subsequent closed-breeding 2 Through the selection of ~7 generations of specialized strains, purebred shelduck ducks with higher annual egg production, annual egg production rate and annual egg weight, lower feed consumption during the annual egg production period and better varieties have been bred, further increasing its economic value.

Description

Technical field [0001] The present invention relates to the field of poultry breeding, and in particular to a breeding method of purebred pork ducks. Background technique [0002] Difficult Ducks, also known as the big divusions, medium and large, mainly produced in Daxie County, Jiangxi Province. The big duck has no white and neck, and the blue is blue, the tibia is yellow. The male duck head, neck, back feather red brown, a few heads with ink green feathers, wings with green mirror feathers. The mother duck is full of brown, there is a large black freckles, the masses call "big granules", and the wings have ink green mirror feathers. Because the numb ducks are stocked in the lake for a long time, they eat fresh fish and shrimp, shellfish and field screws. There is also crisp lotion, so it is very delicate and delicious. [0003] Diffuxia Duck is a "China Livestock Genetic Resource Catalog" of Jiangxi local excellent duck varieties, which is the key protection variety of Jiangxi...
