In the production of laying hens, chicken farmers pay more attention to feed compatibility, environmental temperature and humidity control, regular epidemic prevention, seasonal management, and lighting management, and often overlook the following issues. Timely deterrence is mainly intended to prevent chickens from developing delirium, licking, etc. Usually 6 to 12 days old, the vitamin C and vitamin K should be added to the feed two days before the break, to prevent excessive bleeding and stress on the chicken body. The direction is tilted so that the upper jaw is cut 1/2 and the lower jaw is removed 1/3. Add anti-stress additives to the feed or drinking water 3 to 5 days after the break, and ensure that there are enough troughs and sinks to prevent the chickens from affecting growth due to difficulties in eating and drinking water after they break. In rural areas, chicken farmers often break their eggs at the age of 30-60 days. At this time, the basic growth of quail pods and the rich blood vessels and nerves make it difficult to break the larvae, causing great stress to the chicken body and seriously affecting the chicken's growth and development. It is an important reason for the poor effect of raising chickens. The main purpose of limited feeding is to control the body fat, inhibit sexual maturity, thereby producing more eggs and saving feed. Restricted feeding generally begins at 6-8 weeks of age and ends at 16-20 weeks of age. Feed restriction can reduce the amount of daily feeding and can also reduce the amount of crude protein in feed. When feeding restrictions should be noted: (1) The specific time limit for feeding should be determined based on the average weight of the flock. (2) Diseases, weak and residual chickens should be removed before restriction. (3) Ensure adequate troughs and sinks. (4) Pay attention to the health of the flock and stop feeding immediately if epidemics occur. Elimination of low-yield chickens In actual production, chicken farmers are generally reluctant to eliminate low-yielding chickens, thinking that it can produce a few eggs. Little do they know that low-yielding chickens produce few eggs and eat a lot. In order to save feed and increase economic efficiency, it is necessary to eliminate low-quality chickens in time. The criteria for judging low-yielding chickens are: (1) yellow pods, small crowns, pale, and main wing feathers falling off. (2) The abdominal cavity is small, pubic space is small, cloacal cavity is small and dry. After 11-12 months of compulsory conversion of laying hens, if the chicken production rate is still high, the market price of eggs is also high. To save the time and expense of breeding new hens, the old hens can be forced to moult. Measures to extend egg laying time. The specific method: starting 10-12 days to stop feeding, stop the auxiliary light, only water; 13-19 days feeding breeding materials, the first day of 30 grams / only, after every two days to increase 20 grams; 20 days to start eating freely . Extend daylight for 25 days and increase it by half an hour up to 16 hours each day. Regular insect repelling can effectively prevent various intestinal parasites, reduce feed wastage, improve feed utilization, and reduce costs. Deworming is generally carried out in two batches. The first 2 months of age and the second time before the chicken is opened, 25-30 mg/kg of levamisole is commonly used. In the rural areas, the control of rodent pests is a problem that is often overlooked. Even if some chicken farmers value it, it is often impossible to kill mice without affecting the production of chickens without effective methods. Rats not only eat feed, bite bad objects, disturb chickens, but also spread diseases. Therefore, timely killing of rats is an important measure to reduce feed wastage, reduce disease transmission, and increase economic efficiency. Specific practices: (1) Start with construction and sanitation. Keep hygiene, timely remove feed residue; use cement to block the building's holes. (2) Use a variety of methods to eradicate rats. The feed warehouse uses rodent cats to eradicate rats, and the chicken house uses drugs to eradicate rats and devices to eradicate rats, and it is generally better to use rodents as rodents. Note that during drug eradication, not only the feed in the feed chute should be cleared, but also the chicken cage should be closed to prevent the chicken from poisoning after eating it.
