Autumn is the critical period for high-yielding laying hens

In autumn, various feeds are sufficient. Moulting of adult laying hens has been suspended, and new laying hens have been successively put into production. In this crucial period, feeding and management should be strengthened to increase the egg production rate. Eliminating Old and Weak Hens It is usually best to breed laying hens for 1-2 years, and hens over 2 years old are eliminated. Feed more high-quality feeds such as corn and rice bran to encourage hens to increase their weight and market them in time for sale. When new laying hens begin to lay eggs, new and old chickens should be reared separately, and new chickens are gradually transitioning from pre-production to feeding and management during the laying period. The artificial forced moulting can reduce the illumination time from 16 hours to 8 hours, change the light to low light, change the compound feed to rice bran, straw feed, and add in the feed. In order to replace the minerals with 1%-1.5% of gypsum in the moulting layer, the feathers can be changed in 7-10 days, and the amount of pumpkin and vegetables can be added. The light is then restored for 12-16 hours. New feathers can be grown in 5 weeks, and chickens can be laid in 7-8 weeks. The latest research shows that adding 2.5% zinc oxide to the diet can promote moulting, shorten the moulting time, and lay eggs ahead of schedule. When the egg production rate of full-price diets is 70%-90%, the protein content in the diet is 17%-19%, energy is 2700-2750 kcal, and calcium is 3%-4%. Practice has shown that production starts when every 100 chickens produce 5 to 10 eggs a day. For every 100 kg of feed, 15-20 kg of bean cake, 5-7 kg of fishmeal and blood meal, 5-10 kg of wheat bran, 3 kg of loquat powder, 2 kg of bone meal, 4-5 kg ​​of shell powder, 0.5 kg of salt, multi-dimensional 0.5 kg for mineral supplements, 10 kg for corn, 70%-80% for egg production, 1-3 kg for fishmeal and soybean meal, 1-2 kg for shell flour, and proper bran reduction Skin and corn are fed together. Artificially supplemented with light can stimulate ovulation and increase egg production. When the egg starts to be added, the lighting time is increased by half an hour each week, and every two weeks thereafter, by half an hour, until the lighting time reaches 16 hours per day. Practice has proven that artificial supplemental lighting works best every morning before dawn. When supplementing lighting, the floor of each square meter is 3-5 watts, the lamp is about 2 meters from the ground, and the distance between the lamp and the lamp is 3 meters. The light is evenly distributed throughout the house. In order to keep the environment quiet and reach the peak period of egg production, we must take all effective measures to ensure the quietness of the surrounding environment and prevent fright. Breeding staff should be lighter when working. Do not enter the sheds casually. Special precautions must be taken to prevent harassment of animals such as dogs and cats so as not to cause stress in the flock. To strengthen health and epidemic prevention in early autumn is still hot and humid, high temperature and humidity, susceptible to chicken gizzards, coccidia, egg drop syndrome and other diseases, so strengthen the health and epidemic prevention is to ensure the egg production and stable production of an important part of the chain. One must often clean the chicken house and playground. Food tanks, sinks and other equipment should be regularly disinfected to reduce the incidence of chicken disease. Second, it is necessary to inject Newcastle disease vaccine and chicken cholera immune prevention, and use levamisole, coccidiosis and other deworming. Third, we must observe the chicken house, Qiao knowledge chicken, once the disease is diagnosed and treated in a timely manner, strict disinfection to prevent the spread of bacteria.
