After a long period of egg production and hot summer, laying hens have developed fatigue. After the autumn, they should timely adjust the breeding measures and strengthen management from the following aspects.
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.
Promote simultaneous moulting to reduce the light from the original 14 to 16 hours to 8 hours or less (or change to dark light), stop feeding compound feed for 10 days, and then feed grain feed such as chaff flour and straw powder to supply drinking water normally. 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. After feeding 50 to 100 grams of green vegetables or squash, the mixed feed and light are gradually restored after 3 weeks. After 4 weeks, the new feathers can be lengthened and the eggs can be laid gradually.
Prevention of colds and chicken pox fall into the cold after the fall, especially in the morning and evening temperature difference, chickens are prone to catch cold. The prevention of chicken diseases is first of all to prevent colds. Chickens that have a cold will reduce their resistance and it is easy to develop other infectious diseases. 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.
