Problems solved by technology

The development of the Dayu duck industry has ushered in an opportunity to re-emerge, but the seedlings of the Dayu duck are in short supply. Times have changed. Some duck breeders now only focus on feeding, disease prevention and other technologies, but lack management experience. Affecting breeding benefits, the quality and purity of shelducks are uneven

Embodiment 1

[0034] In the disinfection and sterilization farm, the male duck in the F11 line was used as the male parent, and the female duck in the F12 line was used as the female parent to perform crossbreeding to obtain the F21 line of the three-generation hybrid population. In the present generation, the egg production, egg weight and feed consumption of individual shelducks were detected and measured, and the results showed that: the annual egg production of the individual shelduck was 194, and the annual egg weight was 16.46±0.28 kg, the annual feed consumption during egg production is 68.94±8kg, with good annual egg production, annual egg production rate and annual egg weight, and low annual feed consumption during egg production.

Embodiment 2

[0036] In the disinfection farm, the male duck in the F11 line was used as the male parent, and the female duck in the F12 line was used as the female parent to perform crossbreeding to obtain the F21 line of the three-generation hybrid population, and then the individuals with dominant dominant in the F21 line were closed-breeding for the third In the present generation, the egg production, egg weight and feed consumption of individual shelducks were detected and measured. The results showed that: the annual egg production of this individual shelduck was 225, and the annual egg weight was 18.64±0.51 kg, and the feed consumption during the annual egg production period was 65.56±10kg. Compared with Example 1, it had good annual egg production, annual egg production rate and annual egg weight, and lower annual feed consumption during egg production.

Embodiment 3

[0038]In the disinfection and sterilization farm, the male duck in the F11 line was used as the male parent, and the female duck in the F12 line was used as the female parent to perform crossbreeding to obtain the F21 line of the three-generation hybrid population. In the present generation, the egg production, egg weight and feed consumption of individual shelducks were detected and measured, and the results showed that: the annual egg production of the individual shelduck was 253, and the annual egg weight was 20.54±0.81 kg, and the annual feed consumption during egg production was 63.32±15kg. Compared with Example 2, it had higher annual egg production, annual egg production rate and annual egg weight, and lower annual feed consumption during egg production.

Abstract

The invention discloses a breeding method of purebred sheldrakes. The breeding method comprises the following steps of establishing a line with purebred mountain sheldrakes with small size and high egg yield as a maternal line, establishing a line with purebred Jinding ducks with high egg yield as a paternal line, and hybridizing to obtain a first-generation hybrid population serving as an F1 line. According to the breeding method, the purebred sheldrakes with excellent comprehensive performance are obtained by hybridizing and fusing excellent genes of the purebred mountain sheldrakes which are small in size and high in egg yield, the purebred Jinding ducks which are high in egg yield, purebred Putian black ducks which are heavy in egg weight and purebred Fujian white ducks which are low in feed consumption in the egg producing period. By means of the breeding method, according to the characteristics of mountain sheldrakes, the Putian black ducks, the Jinding ducks and the Fujian whiteducks, the purebred sheldrakes with high annual egg yield, high annual egg laying rate, high annual egg laying weight, low annual egg laying period feed consumption and good variety are bred throughhybridization and subsequent closed breeding of 2-7 generations of specialized strains, and the economic value of the purebred sheldrakes is further increased.

Description

technical field [0001] The invention relates to the field of poultry breeding, in particular to a breeding method for purebred shelducks. Background technique [0002] Dayu Duck, also known as Dayu Shelduck, is medium to large in size and is mainly produced in Dayu County, Jiangxi Province. Dayu duck has no white collar, blue beak, blue-yellow shanks and webs. The head, neck and back feathers of the male duck are reddish brown, a few have dark green feathers on the head, and dark green mirror feathers on the wings. The whole body of the female duck is brown with large black freckles, which is called "big grain hemp" by the public, and the wings have dark green mirror feathers. Since the shelduck has been stocked in the lake for many years, it mainly eats fresh fish, shrimp, shellfish, and snails, as well as crispy lotus and tender water chestnuts, so it is big and tender, tender and delicious. [0003] Dayu Shelduck is an excellent local duck breed in Jiangxi listed in th...
