1. Immunization. Although immunization, injection, chicken or vaccine stimulation will bring strong stress response to the flock, but the protection period of the oil emulsion inactivated vaccine is roughly 6 months, the egg laying peak period of laying hens is roughly 4 to 6 months, so injecting the corresponding oil emulsion inactivated vaccine intramuscularly when the flocking rate reaches 5% can not only allow the birds to survive the peak of production but also avoid the stress caused by immunization. In response, the immunity is reduced and the anus is receded.
2. Scientific lighting. The increase of light can prolong the physiological activity time of laying hens, increase their feed intake, increase the egg production rate and egg weight, but the increase of light or the long illumination time will cause intense stress to the laying hens, which may cause prolapse or Fatigue syndrome and other adverse effects have appeared. It has been proved that the daily increase of 0.5 hours of light from a production rate of 10% is reasonable and has been increased to 16.5 hours.
3 reasonable refueling. Because the number and types of nutrients required for laying hens and other growing stages are different, the nutrient content and quantity contained in hens and young chicken feeds are different, and palatability is also different. Feed replacement is likely to cause flocking. In order to extinguish the anal sex, change the feed to follow the “change gradually from little to more†method, that is, the feed content of the peak layer chickens is gradually increased from the week before the egg production, and completely replaced by the peak of the egg production after 2 weeks. feed.
4. Reduce stress. In order to reduce the various stress responses of the first-laying hens, appropriate amount of vitamin A is added to the feed, and an appropriate amount of vitamin C is added to the drinking water to increase its anti-stress ability, or to be uniformly distributed in the feed at a ratio of 0.5%. Stir in herbal Chinese herbal medicine to prevent prostration.
5. Disease prevention. As early as laying hens have weak constitution and poor basic immunity, they are prone to diseases caused by non-immune diseases such as colibacillosis of chickens, salmonellosis of chickens, and conditional pathogens such as chicken mycoplasmosis, so they should be regularly Add the appropriate Chinese herbal medicine to the diet of layer chickens in the first phase of production or add appropriate amount of western medicine to the drinking water to prevent them.
6. Reorganize the flock. Because there are still stunted chickens in the laying season and the chickens are not up to standard, they will not only affect the egg production rate of the group, but they will not be able to catch up because they can’t get food in the future, so they should be in production. During the rectification period, chickens with lighter weight and poor development were selected to be isolated and even eliminated, so as to improve the uniformity of laying and the egg production rate of the chickens.
7. Equipment overhaul. Equipment damage not only affects the working efficiency of the staff, but also damages the eggs and even poses a threat to the life of laying hens. For example, damage to the drinking water system in the summer can prevent normal drinking, and the rate of laying eggs that affect the production rate of laying hens makes them more thirsty. Death, damage to warm winter facilities can easily cause chickens to catch a cold or die of cold. Damage to chicken cages can cause damage to the eggs or damage to the legs of chickens. Therefore, strict inspection and maintenance of the equipment and equipment of laying hens should be carried out during the opening period.
8. Drive parasites. Parasites parasited in chickens or in vitro can not only absorb nutrients and produce stress, but in severe cases can also cause laying hens to stop production or even die. Therefore, insecticides should be carried out in laying hens. Is the internal parasite (unless there is an ectoparasite), the commonly used anthelmintic drugs are ivermectin and levamisole, ivermectin is usually mixed feed, levamisole is generally sent to use.
