Hybrid seed production method for native chickens

Abstract

The invention discloses a hybrid seed production method for native chickens. The method comprises the steps of breeding of progenitor breeding chickens, a cruel elimination method, breeding of parentgeneration hatching eggs and selection of parent generation breeding chickens. For the bred chickens, hens have a moderate body form, an early producing time, small influence on climate and strong aggressivity, generate chicken grease more early, lay more eggs, have a low death rate and a small activity range and do not easily get lost; cocks have a larger body form than northern cocks, have aggressivity which can directly cause death to small-sized wild beasts, and are loyal guarders of chicken flocks, the missing rate of the population is greatly reduced, since the cocks have a large body form, the flight capability and activity range are smaller than before, therefore, the cocks have a certain amount of subcutaneous fat, and after being cooked, the cocks are smooth and tender in meat quality and delicious and fragrant in taste.

Description

technical field [0001] The invention relates to the technical field of native chicken breed breeding, in particular to a chicken hybrid seed production method. Background technique [0002] Native chicken is a unique high-grade dietary supplement in my country. Although there are native chickens in all countries in the world, our country is famous for its variety, natural breeding, delicious taste and rich nutrition. Native eggs are a good tonic for pregnant women and after serious illness, because of their low cholesterol and high protein, especially the lecithin in native eggs is more beneficial to human health, but the existing free-range chickens, especially the northern breeding scale The chicken is small, the survival rate is low, and the taste of the chicken is not as good as before. The chicken is small, the subcutaneous fat is scarce, the meat quality is relatively woody, and it lacks the original delicious taste. In terms of egg production, it is also affected by t...

Problems solved by technology

Therefore, they are still adapted to local breeding, and there is little change to the chicken body itself. Southern chickens are still larger in size, strong in disease resistance, not easily attacked by small wild animals, and have less impact on the climate during growth, but their cold resistance is poor. The cost of feeding is high. Although the meat is smooth and tender, it is a little fatty. Although the northern chicken has enhanced disease resistance, it is still small in size, vulnerable to small wild animals and easily lost. It is easily affected by the climate during production, and the meat quality is relatively low.
