Embodiment 1

[0019] During the peak period, the core group of white Muscovy ducks from the unselected group and F4 generation white Muscovy ducks from the breeding group each selected 15 full white male Muscovy ducks and 15 black-headed male Muscovy ducks. The rotation method was adopted at the ratio of 1♂:30♀. That is, firstly by artificial insemination, 15 full white male muscovy ducks are crossed with 450 white-feathered half muscovy females (Taiwan white ducks). After 7 days, the breeding eggs are collected and hatched, and the offspring of half muscovy ducks are hatched. Perform feather color measurement, judge feather color grade, and statistically analyze the ratio of each level of feather color of mule duck. Secondly, after collecting the breeding eggs, cross 15 black-headed male Muscovy ducks with white-feathered half-muscovy females of the same group, the same as above. After 7 days, start to collect breeding eggs and hatch, and color the offspring of half-muscovy ducks when they h...

Embodiment 2

[0025] Select male and female breeding ducks from the M18 female parent production group introduced from France to form a basic group, breed the F1 generation core group, select 172 breeding male ducks and white Muscovy female ducks to test, identify the feather color of the offspring, and select The offspring of 42 parent male ducks with all white feather color and grade A were backcrossed with M18 female ducks, and the F2 generation core group breeding ducks were bred. 200 F2 generation M18 female ducks and white Muscovy male ducks were selected to cross, the results (Table 1 and Table 3) The white feather rate of class AB of its offspring half Muscovy duck reached 96.23%, AC 1 Class white feather rate reached 98.14%; at the same time, 200 female ducks were selected from the unselected M18 female parent production herd to cross with male Muscovy ducks. As a result, the AB white feather rate of offspring half Muscovy ducks was 85.87%, and the offspring half Muscovy ducks AC 1 T...

Abstract

The invention provides a breeding method capable of improving a white feather rate and class of semi-muscovy ducks. Male and female parent samples of the semi-muscovy duck are systematically bred by mainly using reciprocal cross, self cross and subculture selection methods. The breeding method has the advantages that the white feather rate and class A of the semi-muscovy ducks can be efficiently and systematically improved, the white feather quality of the semi-muscovy duck is comprehensively improved, the high-quality and first-class feather and the white and attractive carcass are provided for market, the market competitiveness and farming benefit of the semi-muscovy duck are increased, and the method is favorable for promoting the white-feather semi-muscovy duck industry to be developed to a higher level.

Description

Technical field [0001] The invention relates to a breeding method for improving the white feather rate and grade of mule ducks, and belongs to the technical field of animal husbandry. Background technique [0002] Muscovy duck production is a characteristic and advantageous industry in Fujian Province, with an annual supply of more than 100 million seedlings and an annual output of more than 60 million ducks. It is the leading meat duck species in the Fujian market. Feather color is one of the important economic traits of mule duck. The traditional mule duck feather color is black hemp, and there are black needle feathers on the carcass after slaughter, which seriously affects the appearance of the carcass and product sales, and it is difficult to meet the requirements of modern industrial production. The white feather mule duck not only has its white feathers as a precious raw material for the textile industry, and has high economic value; it also has a white and beautiful carc...
