Problems solved by technology

The original Yao chicken is a typical "lean meat" chicken breed, which has the characteristics of compact body, firm and tender meat, delicious meat, strong foraging ability, resistance to rough feeding, and strong disease resistance. The problem of protruding sternum and obvious defects in industrial production, in order to improve the growth performance of native Yao chickens while retaining their breed characteristics, it is necessary to select and breed them

Embodiment Construction

[0017] A method for cultivating green-footed Ma chickens, comprising the following steps:

[0018] One, the preparation of green-legged female parent: take common dark hemp feather Yao chicken as the male parent, and medium-speed Ma chicken as the female parent to carry out hybridization to obtain the F1 generation. The F1 generation cock is yellow-legged and is not selected; the hen is green-legged. reserved for use;

[0019] 2. Secondary crossbreeding: take the ordinary deep hemp feather Yao chicken as the male parent, and the F1 generation hen as the female parent, carry out secondary crossbreeding, and obtain the F2 generation, and the male and female hens in the F2 generation are all green feet;

[0020] 3. Closed breeding: closed breeding of the F2 generation, with body weight, precociousness, and coat color appearance as the selection indicators, three generations were continuously selected to obtain a mature new strain of Heiyao chicken. Compared with the original Hei...

Abstract

The invention discloses a breeding method of green-leg partridge chickens. The method includes the following steps: taking black Yao cocks as male parents, taking medium-speed partridge chickens as female parents, obtaining F1 generation through hybridization, and selecting green-leg partridge chickens in the F1 generation as F1 generation female parents; taking the black Yao cocks as the male parents, taking the F1 generation hens as the female parents, and performing secondary hybridization to obtain F2 generation; and taking the green-leg male and female individuals in the F2 generation toperform closed breeding, taking weights, precocity and coat color appearance as breeding indexes, and performing continuous breeding for at least three generations so as to obtain a new mature strainof the green-leg partridge chickens which is the new strain of dark partridge Yao chickens. The medium-speed partridge chickens are introduced to perform hybridization, fixed body appearance characteristics can be achieved through closed breeding, and the Yao chicken breeds with better growth speed and more uniform coat color can be bred; and compared with original black Yao chickens, the strain is faster in growth speed, better in precocity, more consistent in crowning and more muscular in pectoral and leg muscle; and the strain maintains the appearance characteristics of the black Yao chickens, namely, the strain has green legs and dark spotted feathers, and the feet of a part of individuals have fur.

Description

technical field [0001] The invention relates to a method for cultivating chickens, in particular to a method for cultivating green-footed Ma chickens. Background technique [0002] Yao chicken is originally produced in the Yao villages of Lihu and Baxu, two ethnic towns in Nandan County, Guangxi, at an altitude of 800 to 1,000 meters. Nandan Yao chicken has been famous for a long time and is one of the four famous chickens in Guangxi. Native Yao chickens can be divided into Hongyao and Heiyao. Hongyao roosters have golden feathers, hens have ephedra feathers, Heiyao roosters have yellow-black feathers, and hens have hemp-black feathers. Currently, the market is dominated by Heiyao. Native Yao chicken is a typical "lean-meat" chicken breed. It has the characteristics of compact body, firm and tender meat, delicious meat, strong foraging ability, resistance to rough feeding, and strong disease resistance. The problem of protruding sternum and obvious defects in industrial pro...
