Laying hens are at the late stage of egg production after 350 days of age (the egg production rate is below 80%). This stage is the period when eggs are slowly falling, which is an important stage to increase the profit of breeding. The author believes that the rearing and management of laying hens should be done in the following aspects: I. Reasonable control of nutrients in the feed of laying hens 1, appropriately reduce the energy and protein levels in feed As a result, the egg production performance of the flock gradually declines, and the nutrients of the egg production are converted into fats, which leads to a great increase in fat deposition and susceptibility to diseases such as fatty liver diseases. The excess protein is not fully utilized, resulting in waste. Therefore, the energy and protein of the feed are reduced during the late stage of production to adapt to the reasonable supply of nutrients for later egg production. 2, increase the crude fiber content The egg production performance at the end of the laying period is gradually declining, and the nutrient demand should be appropriately reduced in comparison with the previous and middle stages. However, the body weight in the later period cannot be reduced, and the normal demand needs to be maintained. In order to give the body a feeling of fullness, the crude fiber content in the feed should be increased, and other factors should be reduced. The nutrient concentration of the ingredients. 3, timely calcium After the peak of egg production, chickens consume a lot of calcium, and the ability of the birds to absorb and use calcium decreases later. Therefore, the level of calcium in the diet should be increased. Second, grasp the feeding and management of late-stage egg production 1, regularly check the weight In order to prevent the occurrence of partial body fat in the chickens due to the decline in the performance of the subsequent laying, the body weight was measured once a month and compared with the standard body weight and the body weight of the previous month. For partial fat and partial chicks, they were restricted by feeding and increased nutrition. 2. Timely elimination of widow chicken With the decline in the performance of late egg production, there will be a part of low-yielding chickens in the flock. Through the observation of the appearance, turning the anus during insemination can be singled out and eliminated to reduce feed wastage. 3, reduce stress Reduce the impact of various stress factors such as high temperature, cold stress, water stoppage, power outage, and noise on the production of chicken eggs so that the egg production performance can be reduced steadily. 4. Stable chicken house keepers Improve the importance of the breeder's late management of the flock: If a performance appraisal plan that adapts to the decline in the performance of the later laying eggs is formulated to promote the employees to not reduce the income due to the decline in the performance of the subsequent egg production, the work enthusiasm is enhanced. 5, do a good job in the late stage of the production of eggs and health management Adhere to environmental disinfection work, reduce the concentration of pathogenic microorganisms in the environment, reduce the occurrence of conditional diseases; do a good job in drinking water disinfection; timely reimbursement, maintain the chickens to maintain a uniform and effective antibodies, and enhance the disease resistance of chickens. 6, do a good job in the late egg production chicken oviduct inflammation control In the late stage of chicken production, the ability of the fallopian tube to secrete mucus is reduced, which may cause the occurrence of fallopian tube inflammation such as prolapse of the rectum and brown eggs. Therefore, some antibiotics such as amoxicillin, levofloxacin, and ciprofloxacin are suitable to be administered at this stage, which can reduce the mortality of chickens and the occurrence of fallopian tube inflammation.
