Sanhuang chicken is native to Ningdu County, Jiangxi Province, and is small in size. The cock has a huge bright red comb, the hen's comb is upright and small, and the eggshell under the Sanhuang chicken is light brown.
When raising Sanhuang chickens by flat cultivation, it is necessary to spread a layer of padding on the ground in the henhouse, and the thickness of the padding is about 10 cm. The padding has the advantages of no mildew and strong adsorption. Sawdust, rice husk, rice straw or corn stalk can be used to create a comfortable environment for Sanhuang chicken.
When raising Sanhuang chickens online, it is necessary to build a grid at a height of 50-60 cm from the ground. You can use plastic net or barbed wire to make Sanhuang chicken live online every day. Although this method has high investment, it can keep Sanhuang chicken from touching chicken manure.
Method for improve egg yield
1. Scientific research and production practice have proved that feeding restriction technology is an effective means to improve the physiological characteristics of chickens and increase egg production. Therefore, in order to improve egg production, it is necessary to implement feeding restriction technology. The handle can be changed manually. The persistence of resting and spawning in winter can be changed by the choice of brooding season and artificial lighting.
2. Egg production is an important quantitative trait of chickens, which is closely related to the physiological state, genetic factors, nutritional conditions and external environmental conditions of chickens. It is a very effective and main technical means to improve the egg production of Sanhuang breeders from the perspective of genetic breeding.
3. Improving the local environmental conditions of breeder's life is an important aspect to improve the egg production, including the idea of controlling the temperature of henhouse at 15℃ ~ 25℃ as far as possible, reducing the stress of various factors and providing a comfortable and quiet environment.
