Measures to Decrease the Egg Production Rate of Chickens in Autumn

In the autumn, new chickens start to lay eggs, and the old chickens' moults cease production. In order to prevent the egg production of chickens from falling, the following tasks should be focused on. 1, choose to stay high-yield chickens and eliminate low-yielding chickens. In the early spring and autumn, layer chickens are usually selected for culling. In the autumn, chickens are mainly selected. High-producing laying hens generally have smaller bodies, compact feathers, lighter colors such as feet and slugs, heads and tails are upturned, heads are wide and short, eyes are divine, crowns and flesh are well developed, bright red, abdomen is large and soft, elastic, and cloacal The opening is flat and round, large and moist; tame, strong foraging, large feed intake; long duration of egg production, late feathering and fast, and early recovery of egg production. The low-yield chickens are often over-fat or over-weight, have a dull temperament, have poor feeding habits, and have small, pale flesh. Most of the chickens with early moulting and production discontinuity are low-yielding chickens and sick chickens and should be eliminated. 2, to provide nutritious feed. In order to promote the chickens to reach the peak of egg production and prolong the peak period of egg production, feeds should be fed to high-protein, high-energy, and high-vitamin-content feeds. The protein content should reach 18%. When laying hens are moulted, disease resistance and metabolic function are weakened, and they must be fed with easily digestible high-quality feeds and Vitamins. In particular, the content of b vitamins should be sufficient. At the same time, 1% to 2% gypsum powder should be added to the diet to supplement sulfur and calcium. Feeding methods can be used for free food, especially before and after lights out, you must feed enough and drink enough water. During the laying period, feed nutrients and varieties should be kept as far as possible, and feeding methods should be kept unchanged so as to avoid stress and affect egg production. 3, artificial force moulting. The implementation of artificial forced moulting can synchronize the moulting of the chickens and the moulting is quick and neat, restoring the peak of egg production, long duration and good egg quality. Compulsory moulting usually includes hunger, chemical, and hormone methods. However, chemical methods are used to prevent overdose from causing poisoning. 4, supplement artificial lighting. As the day falls in autumn, it takes time to make up for the light. The method is to add 40 watts of electric light in the chicken house. Each light will be turned on sooner or later for a certain period of time. The switch light time must be the same every day. The light intensity is 20 lux and the daily light is 14-16 hours. However, during the moulting period, in order to accelerate the moulting process of the layer, the illumination time may be appropriately reduced. 5, master the appropriate temperature and humidity. Provide a good environment for chickens and maintain proper temperature and humidity. The suitable temperature for laying hens is 13°C～24°C, and the relative humidity is 55～70%. After the fall, there is a large temperature difference between day and night. At night, it is necessary to pay attention to appropriate insulation, while paying attention to ventilation. 6, develop a reasonable immunization program. According to the epidemic characteristics of the local epidemic, a reasonable immunization procedure should be established, and a high quality vaccine should be used to immunize according to the prescribed dose and operation method. After passing through an egg production period, the old chickens will have poor physical condition at the end of autumn and are prone to infectious diseases. It is also necessary to strengthen the epidemic prevention. When immunizing, in order not to affect chicken egg production, a variety of vitamins need to be added in the diet to improve the chicken's constitution.

Hair Care & Growth

Alopecia is the phenomenon of hair falling out of the scalp. The hair that normally falls out is the hair in the degenerative and telogen phases, because the hair entering the degenerative phase and the newly entering the growing phase are constantly in a dynamic balance.
