Embodiment

[0027] A method for selecting and retaining roosters with high feather maturity at the time of listing, comprising the following steps:

[0028] Step 1. Select the reserve rooster:

[0029] Weak seedlings were eliminated when Qingyuan Ma chicken eggs were hatched, and the males and females were identified by turning the anus, and 160 healthy 1-day-old Qingyuan male chickens were selected as reserve breeding roosters, and Qingyuan was compared according to the fast-feather male seedling group and the slow-feather male seedling group The male Ma chicken seedlings are classified and numbered, among which there are 80 males of the fast-feather Qingyuan Ma-chicken and 80 males of the slow-feather Qingyuan Ma-chicken;

[0030] Step 2, measure feather parameter:

[0031] Use a vernier caliper to measure and calculate the main wing feather length and cover main wing feather length of each Qingyuan Ma pheasant seedling, where the main wing feather length is the third and fourth main w...

Abstract

The invention discloses a method for selecting and keeping cocks with high feather maturity when going on the market. The method can improve the feather maturity of fast feathered pure cocks when going on the market through forward selection of the feather length of main wings, the feather length of covering main wings, the feather length average value or the feather speed difference, and can improve the feather maturity of slow feathered pure cocks when going on the market through backward selection of the feather length of main wings, the feather length of covering main wings, the feather length average value or the feather speed difference, thereby reducing the breeding quantity of fast feathered pure cocks or slow feathered pure cocks and reducing the breeding cost.

Description

technical field [0001] The invention relates to the technical field of poultry selection and retention, in particular to a method for selection and retention of roosters with high feather maturity when they go on the market. Background technique [0002] With the improvement of people's living standards, high-quality broilers are more and more favored by consumers. When broiler chickens are on the market, the growth and development of feathers will directly affect the appearance of the carcass after slaughter, especially for breeds with dark feathers, such as Qingyuan Ma chicken. Leaves black spots on the skin, which affects broiler quality. Therefore, feather maturity is one of the important factors affecting broiler quality and sales quantity. [0003] The fast and slow feathers of the chicken are a pair of sex-linked genetic traits, which are used to separate the sexes of the newborn chicks of the commercial generation, that is, to use the slow-feather pure line hens to...
