A method for improving the hybridization of Northeast colorful pheasants and native chickens

Abstract

The invention discloses a northeast colored pheasant and native chicken hybridization and improvement method, and relates to cultivation method for poultry new species. The northeast colored pheasantand native chicken hybridization and improvement method comprises the following steps: selecting a female native chicken and a male northeast colored pheasant, carrying out mixed culture to lay eggs naturally, and hatching fertile eggs to obtain first F1-generation hybrid chickens; selecting a male native chicken and female northeast colored pheasant, carrying out mixed culture to lay eggs naturally, and hatching fertile eggs to obtain second F1-generation hybrid chickens; hybridizing by using the first F1-generation hybrid chickens as female parents and male northeast colored pheasants as male parents to obtain F2-generation hybrid chicken; and hybridizing by using the F2-generation hybrid chickens as female parents and taking the second F1-generaton hybrid chickens as male parents to obtain hybrid pheasant new species. The production performance of the obtained hybrid pheasant new species can be greatly improved, the hybrid pheasant new species are high in disease resistance, wide inadaptation, is heavily gamey and nutrient-rich, and has rich texture, and thus, the northeast colored pheasant and native chicken hybridization and improvement method has the characteristics of low feeding cost, large market sales volume and high profit.

Description

technical field [0001] The invention relates to a method for cultivating new breeds of poultry, in particular to a method for cultivating new breeds of hybrids between exotic chicken breeds and local native chickens, and in particular to a method for improving the hybridization of Northeast colorful pheasants and native chickens. Background technique [0002] Ring-necked pheasant (scientific name: Phasianus colchicus, English name: Common Pheasant), common name pheasant, pheasant, pheasant, collared pheasant, wild pheasant, colorful pheasant, the English name is literally translated as common pheasant. The eyebrows are white, and there is a prominent white ring under the neck, hence the name. There is a leather distance behind the feet, which can be used as a weapon to attack the enemy. It is the most widely distributed bird in the pheasant family in my country. Habitat in bushes, bamboo bushes or grasses in middle and low mountains and hills. Good at running, flying fast...

AI Technical Summary

Problems solved by technology

However, most local chicken breeds in my country lack systematic breeding, self-propagation and self-raising seed production models are common, and the inbreeding coefficient of breeds is high, resulting in reduced viability of chickens, high mortality rate, slow growth rate, and uniformity. Difference

More importantly, the commercial generation chickens obtained from single-breed production are the same as the breeder chickens, and the sale of commercial generation chickens is equal to the sale of the original breed, resulting in a loss of control over the provenance

The Northeast colorful pheasant has an active personality and is good at running. It has sweet meat and a large body weight. Adult roosters can reach more than 3KG, and hens can weigh more than 2KG. It is suitable for mountain and jungle breeding.
