Breeding method of fast-growing green-shin sparkle-feather broiler chicken

Abstract

The breeding method comprises the following steps: firstly, selecting male fast-growing green-shank and white-feather broilers as progenitor male parents, fast-growing female green-foot partridge chickens as progenitor female parents 1 and fast-growing female iron-foot partridge chickens as progenitor female parents 2, and separately breeding the fast-growing green-shank and white-feather broilers, the fast-growing female green-foot partridge chickens and the fast-growing female iron-foot partridge chickens; the female chickens are fed with daily ration added with 800 IU / kg of vitamin D3 and 500 IU / kg of vitamin E after three weeks old; recessive white feather broilers with the weight larger than 2700 g after 150-160 days are selected to be fed to the progenitor male parents, and partridge chickens with green feet and partridge chickens with the weight larger than 1800 g after 170-180 days are selected to be fed to the progenitor female parents 1 and the progenitor female parents 2; hybridizing the progenitor male parent with the progenitor female parent 1, hybridizing the green-shin male offspring as a male parent, hybridizing the progenitor male parent with the progenitor female parent 2, and hybridizing the green-shin female offspring as a female parent; carrying out parent cultivation; and screening the male parent and the female parent, and hybridizing the male parent and the female parent to obtain a commercial generation.

Description

Technical Field

[0001] The invention relates to the technical field of edible chicken breeding and cultivation, in particular to a breeding method for fast-growing large-sized green-legged and hemp-feathered broilers. Background Art

[0003] Broilers are an important part of my country's poultry industry. With the development of my country's economy and the improvement of people's living standards, consumer demand is constantly changing. The demand for blue-legged broilers is increasing, bringing huge development space for broiler production companies. Summary of the invention

[0005] In view of this, the present invention provides a method for breeding fast and large-sized blue-shank and hemp-feathered broilers.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A method for breeding fast and large-sized green-legged broiler chickens comprises the following steps:

[0008] Step 1: Select 150-160 day old male fast-growing blue-legged white-feathered broiler chickens as the grandparent father, select 170-180 day old female fast-growing blue-legged Ma chickens as the grandparent mother 1, select 170-180 day old fast-growing iron-legged Ma chickens as the grandparent mother 2, and cultivate them separately; and after the female individuals are three weeks old, feed them with 800 IU / kg vitamin D3 and 500 IU / kg vitamin E in the diet;

[0009] Step 2: hybridize the ancestral male parent with the ancestral female parent 1, and select the blue-shank male offspring as the paternal parent; hybridize the ancestral male parent with the ancestral female parent 2, and select the blue-shank female offspring as the female parent; and then cultivate the parents according to the specified conditions;

[0010] Step 3: Screen the paternal and maternal parents;

[0011] Step 4: After hybridizing the male and female parents, large blue-legged and hemp-feathered broilers are obtained.

[0012] As a preferred solution, in step one, the fast-growing green-legged white-feathered broiler breed is a recessive white-feathered broiler, the fast-growing green-footed Ma chicken is a Fengxiang green-footed Ma chicken, and the fast-growing iron-footed Ma chicken is a Xingguang iron-footed Ma chicken.

[0013] More preferably, the selection criteria of the male fast-growing large-sized blue-shank and white-feathered broiler chickens are blue-shank, white-feathered, fast-feathered, large-sized, broad-chested and thick-legged, well-developed muscles, and short-tailed feathers;

[0014] The selection criteria for the fast-growing female green-legged chickens are green shanks, nubile feathers, fast feathering, good early maturity, good reproductive performance, large body size and weight, and fast growth rate;

[0015] The selection criteria for the fast-growing female iron-legged chicken are green shanks, nubile feathers, broad chest, fast growth rate, good reproductive performance, and early sexual maturity.

[0016] As a preferred solution, in step 2, the prescribed conditions are: the temperature is controlled at 36-38°C and the humidity is controlled at 50-60% in the first week of cultivation; the temperature is controlled at 34-36°C and the humidity is controlled at 45-55% in the second week of cultivation; the temperature is controlled at 34-36°C and the humidity is controlled at 40-50% from the second week of cultivation to hatching; after hatching, the temperature is lowered at a rate of 0.5°C per day until it is the same as room temperature, the humidity is increased to 60-70% after hatching, and maintained at 50-60% two weeks after hatching.

[0017] As a preferred solution, in step three, the screening is to eliminate individuals with unclear precocious traits and smaller body size, and give priority to retaining individuals with nubby appearance and larger body size and weight.

[0018] Compared with the prior art, the present invention has achieved the following technical effects:

[0019] (1) The fast-growing green-shank hemp-feathered broiler chickens bred by the present invention have a weight of more than 2000 g at 90 days of age, a slaughter rate of more than 93%, and have the advantages of fast growth rate, short breeding time, and high production efficiency, which can meet the needs of the high-end consumer market;

[0020] (2) The present invention uses the Qingjiao Ma chicken and Tiejiao Ma chicken, which have delicious meat and high market acceptance, as the grandparent mothers. The offspring cultivated by the present invention solve the problem of decreased chicken quality. The cultivated Ma-feather broilers have a neat appearance, good meat quality, and delicious meat flavor. BRIEF DESCRIPTION OF THE DRAWINGS
