However, due to its slow growth rate, low egg production and high feed-to-meat ratio, the production cost is high, which is not conducive to large-scale farming
In recent years, due to the impact of foreign species, the species has degenerated and is facing the danger of extinction, and the population size is small, lacking further breeding and population expansion

Embodiment Construction
[0027] A pheasant purification and breeding method includes the following steps:
[0028] (1) Starting from the zero generation, each generation is separated by 12 months. The breeding pheasants are fed into small rooms with playgrounds according to their families. Male and female pheasants mate randomly in the small rooms to ensure the color of the pheasants. Neat, bright, suitable for pheasant characteristics, easy to identify and select according to standards; each generation starts with hatching, weed out miscellaneous and weak young. Properly extend the generation interval to delay the increase of the inbreeding coefficient, the general generation interval is 1 year;
[0029] At the end of the 30-day-old brood for the first time, weed out the offspring with stunted growth and variable coat color;
[0030] For the second time at the age of 90 days, we weighed and calculated the average number. Choose a large, well-proportioned, well-developed pheasant that meets the standard of ...

Abstract
The invention discloses a breeding selection method for pheasant. The variety breeding method combines individuals with families and breeds according to feather color, adult weight, body size, growth and development law, age at first egg, egg yield, egg weight, egg fertility rate, hatching rate, genetic diversity, fast and slow feathering and the like of the pheasant. By means of the breeding method, the pheasant is featured with neat appearance, thin skin, tender meat, fresh meat, delicious egg, much yolk, high dressing percentage, fast growth speed, early sexual maturity, high feed conversion, crude feed tolerance, strong disease resistance and stress resistance, stable production performance and the like, under the normal feeding conditions, the weight of a male pheasant can arrive at 1.4 kilograms when the male pheasant is 140 days old, the weight of a female pheasant can arrive at 1.1 kilograms when the female pheasant is 180 days old, and the marketing uniformity of the same sex is more than 85%; the breeding selection method for the pheasant is suitable for large-scale feeding.
Description
Technical field [0001] The invention relates to a method for purification and breeding of pheasants, belonging to the technical field of agricultural breeding. Background technique [0002] Pheasant, also known as colorful pheasant, has delicious meat, beautiful figure, bright plumage, and has many excellent properties and potential productivity. It has long been loved by consumers. However, due to its slow growth rate, low egg production and high feed-to-meat ratio, the production cost is high, which is not conducive to large-scale breeding. In recent years, due to the impact of foreign species, the species has been degraded and faced the danger of extinction, and the population is small, lacking further breeding and population expansion. Therefore, it is urgent to carry out matching line selection and hybridization experiments on the basis of pheasant species conservation and purification and breeding, to cultivate high-quality new varieties with excellent production performan...
