On August 27th, Associate Professor Zhang Jianqin of the Academy of Sciences and Faculty of Northwest Agriculture and Forestry University told Baoji about chicken breeding technology. She said that after a long period of egg production and hot summer, the chicken body is very tired and should be managed from the following aspects after autumn. .
Increase feed nutrients should be fed with more animal protein feed, supplement chickens that have not yet been moulted to continue egg production, and promote chickens that have been moulted to quickly grow into feathers as soon as possible to resume production. Since the nerves of chickens in autumn are very sensitive, when feeding more highly nutritious feeds, they must be fed slowly so that the chicken's nerves are not stimulated and the moult ceases production.
Timely updates of common laying hens are only used for 1 to 2 years, and it is advisable to feed them for up to 3 years. First, the old and the weak hens were bred and raised separately. They were raised before the moulting. The rations were supplied according to the feeding standards of the hens, and the light was increased to 14 to 16 hours, so that the hens were eliminated and the moult was delayed. When eggs drop below 60%, they can be sold.
Motivate the simultaneous moulting to reduce the light from the original 14 to 16 hours to less than 8 hours (or change to dim light), stop feeding compound feed for 10 days, and then feed the roughage such as husk flour and straw powder to normally supply drinking water and Diets containing 1% to 1.5% calcium sulphate (genetic gypsum) instead of mineral feed, a large number of laying hens will be moulted one after another in 5-8 days, and grain feeds such as grain and sorghum will be fed after 10 days. Add 50 to 100 grams of vegetables or squash, gradually return to compound feed and light after 3 weeks, generally after 4 weeks, the new feathers can grow long and gradually begin to lay eggs.
To prevent colds and chickenpox, the weather turns cold after autumn, especially if there is a large temperature difference between morning and evening. Chickens are prone to catch cold. The prevention of chicken disease is first of all to prevent colds. Chickens that have colds will reduce their resistance, and it is easy to develop other infectious diseases. Therefore, it is not advisable for chickens to be put on the playground. Chicken pox occurs in the late autumn when it is opened. When young chickens are susceptible to infection, prevention should be done. The emphasis is on mosquitoes and moisture.
