High-yielding measures for overwinter layer chickens

In winter, the climate is cold and the sunshine hours are short. Usually the egg laying rate of laying hens declines or even stops production. In order to ensure high production and stable production of layer hens in winter, the following measures must be taken in feeding and management: Timely adjustment of rations in ration preparation should be appropriate. Increase energy feed and reduce the proportion of protein feed. At the same time, it is necessary to meet the need of various vitamins and minerals for laying hens. It is advisable to eat 3 to 4 times for free feeding or daily feeding. Cage chickens pay attention to supply sand. Timely reorganization of chickens Before the start of production, the chickens raised in the same year shall be bred or eliminated from the same group of chickens that are emaciated, diseased, poorly developed, and have bad habits. Strengthen the heat preservation measures The most suitable temperature for laying hens is 16~23°C. According to the situation, the temperature in the broiler house can be increased in the form of stove, fire wall, heating, and plastic greenhouse. Ground layer chickens can be increased in temperature by increasing the stocking density or warming the shed. The breeding density can increase to 6 to 8 per square meter. The floor of the house is kept dry and clean. The house must be closed tightly, and ventilation and ventilation should be taken care of at the right time. Artificial light supplements take a short period of natural light in winter and artificial light supplements are required to make the light for 14 to 16 hours per day. Do a good job of health and disease prevention layer laying hens at the age of 18 weeks (2 weeks before the start of production) Newcastle disease I system vaccine, flu vaccine, bird flu vaccine, fowlpox vaccine vaccination and levamisole deworming. In addition, we must do a good job in environmental hygiene. Avoid stress factors Management personnel must have order and regularity when entering or leaving the chicken house. All operations should be light and light, especially to prevent panic and chicken-induced panic. Keep the environment relatively quiet and stable.
