Seven attention to efficient chicken raising in spring
The spring climate changes from cold to warm, the temperature gradually rises, and the sunshine gradually extends. It is the most vigorous season for chickens to lay eggs. At this time, pay special attention to careful management:
1. Keep warm
The climate in spring is cold and changeable, which brings a lot of inconvenience to chicken production, especially the impact of low temperature on laying hens is very obvious. Therefore, under normal circumstances, it is possible to appropriately increase the stocking density, close doors and windows, add grass curtains, drink warm water and heat from the stove to keep the chicken house at a minimum temperature of 3℃~5℃.
2. Ventilation
Due to the low temperature in spring, the doors and windows of the chicken house are tightly closed, and the ventilation is reduced. However, the exhaust gas from the chicken and the ammonia, carbon dioxide, hydrogen sulfide and other harmful gases produced by the fermentation of the chicken manure will accumulate in the chicken house and easily induce the respiratory tract of the chicken. And other diseases. Therefore, the relationship between ventilation and warmth must be properly handled in spring chicken raising, and the feces and debris in the chicken house should be removed in time to ensure the fresh air in the chicken house. When the weather is good at noon, the windows should be opened to ventilate, so that the air in the house is fresh and the oxygen is sufficient, so as to prevent problems before they happen. But be careful when ventilating, do not let the cold wind blow directly on the chicken body to prevent the chicken from catching a cold.
3. Dehumidification
In the spring, the ventilation in the chicken house is small, and the amount of water evaporation is reduced. In addition, the hot air in the house will condense into a large amount of water droplets when it comes into contact with the cold roof and walls, causing excessive humidity in the chicken house and creating a large number of bacteria and parasites. Conditions. Therefore, in spring, we must strengthen management, pay attention to keeping the chicken house clean and dry, repair damaged sinks in time, avoid overfilling when adding water, and it is strictly forbidden to splash water on the floor of the house.
Four, disinfection
The disinfection work should run through the whole process of raising chickens. In spring, the temperature is lower and the frequency of bacterial activity decreases. However, the spring weather is cold and the chicken’s resistance is generally weakened. If disinfection is neglected, it is very easy to cause disease outbreaks and cause heavy losses. Therefore, disinfection must be done well in spring and disinfection should be carried out regularly.
Five, supplementary photos
Light is the driving force of all life activities. In spring, the days are short and the nights are long, and the laying hens often fall in egg production rate due to insufficient light. In order to overcome this natural defect, artificial supplementary lighting can be used to make up. Under normal circumstances, the total time of light per day should not be less than 14 hours, but also can not exceed 17 hours (more than 17 hours will cause physiological disorders of the chicken). For example, the natural light during the day is 12 hours, and artificial supplementary light is required for 2 to 5 hours every day.
Six, increase energy
Chickens rely on energy feed into the body to obtain heat to maintain their body temperature. The lower the outside temperature in spring, the more heat the chicken consumes to keep out the cold. According to measurements, the feed consumption of chickens in spring is about 10% higher than that in other seasons. Therefore, sufficient energy feed must be ensured in the feed of spring chickens. In addition to ensuring a certain proportion of protein, high-energy feed containing more starch and sugar should be appropriately added to meet the physiological and production needs of chickens.
Seven, strong body
The resistance of chickens in spring is reduced, and special attention should be paid to epidemic prevention and disease prevention, and regular vaccination should be carried out. According to the actual situation, some preventive drugs can be given regularly and targeted to appropriately increase the content of vitamins and trace elements in the feed, enhance the physique of the chicken, improve the chicken’s ability to prevent disease and production, and improve the efficiency of breeding.
