After a large number of laying eggs in the spring and summer seasons, laying hens have a moulting stage in the fall. Natural moulting chickens, time before and after the uneven, early repairs moulting earlier; late feathering layers of thin layers of egg shells, egg weight reduction, fertility rate and hatching rate also decreased. As the flock consumes feed during this period and raises the cost of feeding, many people use a method of restricting feeding, limiting the amount of water, and limiting light to artificially force moulting. To take this approach, the first is to destroy the physical foundation of the chicken; the second is to take a long time, the laying hens can recover eggs in about 50 days. The specific method is: to increase 2% of zinc in the chicken diet, after 3 days of feeding, the amount of gall of laying hens dropped by 50%, and 1/3 of their feathers fell off. About 9 days after feeding, almost all production stops, 80% of feathers fell off, and zinc was stopped in the diet on the 12th day. At this time, chicken feathers were also basically replaced. New feathers sprouted and eggs began to recover. About 20 After about a day, the egg production will return to normal. This method is simple and easy, it can prompt the laying hen to finish moulting quickly, and it has no bad influence on the flock. Cleaning Engineering For Hospital
