Problems solved by technology

[0004] However, compared with domestic ducks, female Muscovy ducks take a long time to grow, which leads to increased feeding costs and less annual egg production. Moreover, female Muscovy ducks are very nesting, which leads to the degeneration of their ovaries and early stoppage of production, and limited reproductive capacity. Restricted the development of intensive and large-scale breeding of muscovy ducks, and the flavor of duck meat was affected at the same time

Embodiment 1

[0079] Taking the male line of white-feathered Muscovy duck being cultivated by Anqing Yongqiang Agricultural Technology Co., Ltd. as the sub-breeding group, considering the growth rate, meat production rate and reproductive performance of female ducks, select healthy, strong and excellent individuals Reserved for breeding to form a high-quality duck base group.

[0080] A total of 80 families were established for the male parent line, and all were weighed at the hatching, 6-week-old, 12-week-old, and 24-week-old respectively, and 5% of the individuals were weighed at other ages to establish the weight data of the line selection.

[0081] Male ducks mainly adopt individual selection, and female ducks record egg production and average egg weight at 62 weeks and 82 weeks respectively, as one of the basis for female duck family selection; female ducks adopt the method of family selection combined with individual selection.

[0082] The specific selection methods are:

Embodiment 2

[0092] The terminal male parent in the muscovy duck strain established in Example 1 is the breeding group of the muscovy duck strain. Meat quality, feed conversion rate, and growth rate were used as the main selection indicators for strains, and the 66-week-old egg production of the previous generation was used as the basis for selection of female ducks. Male ducks: 1:5 for female ducks, according to families and individuals, collect egg markers every day for pedigree incubation. Select 4-6 female chicks for each duck, 6 male chicks for each family, 10,000 basic breeding groups for each generation, and more than 1,000 female ducks and 200 male ducks for the test group. 200 families. Subculture selection is based on the growth rate of male ducks at each stage, the age of female ducks at the beginning of production, and the number of eggs laid at 60 weeks of age. The body weight of male ducks (X+5%) and female ducks (X+10%) of the core group, where X is the body weight of the ...

[0098] Example 3 Detection of Lean Meat Rate, Meat Quality and Flavor Traits of Muscovy Duck Lines in Each Generation

[0099] Meat flavor traits are one of the important selection indicators for male parents. Due to the characteristics that cannot be directly measured, they are tested based on basic data such as muscle tenderness, inosinic acid, and fatty acids. The method of testing is to select 84-day-old male ducks and 20 female ducks of 63-day-old male and female breeding offspring for each generation to measure shear force, flesh color, pH value, Drip loss rate of breast muscle, cooking loss rate of breast muscle and other indicators.

[0100] The Muscovy duck cultivated according to the above method was tested for meat quality and flavor traits, and the test results are shown in the following table:

[0101]

[0102]

[0103] It can be seen from the above table that after two consecutive generations of breeding, the shear force of the breast muscle of Muscovy duc...

Abstract

The invention discloses a breeding method of Muscovy ducks. The method comprises the following steps: selecting breeding standards of male Muscovy ducks and female Muscovy ducks; establishing a new Muscovy duck strain biotechnology-assisted breeding system; and breeding the Muscovy ducks according to the biotechnology-assisted breeding system and the breeding standard. According to the method, characters such as growth rate, meat production rate and reproduction are taken as main characters, molecular marker assisted breeding is combined while breeding is carried out, and the gene molecular marker is applied to new Muscovy duck strain breeding, so that the problems that the strain breeding progress is slow, and recessive characters cannot be removed by conventional selection are solved; the breeding supply capacity, the duck meat quality and the feed conversion efficiency of the Muscovy duck core group are improved, and an advanced breeding technology is provided for breeding enterprises. The Muscovy ducks bred by the method meet market requirements and are suitable for popularization and application of the Muscovy ducks in an intensive production mode.

Description

technical field [0001] The invention belongs to the field of seed breeding, in particular to a method for selecting and breeding Muscovy ducks. Background technique [0002] Duck meat is an important lean protein source for Chinese consumers. It has a unique flavor and is rich in unsaturated fatty acids beneficial to human health, accounting for about 20% of poultry consumption. The production, consumption and trade of my country's meat duck industry ranks first in the world. According to statistics from the World Food and Agriculture Organization (FAO) and the General Administration of Customs of China, China imported 40,000 tons of duck meat in 2018. At the same time, it is also the world's largest exporter of duck meat and duck liver, reaching 376,000 tons. Affected by factors such as the decline in live pig production in 2019, the volume of meat ducks sold and the market price rose rapidly, surpassing the level of 2015-2018; from the perspective of foreign markets, sinc...
