The weather in spring is still cold and the green feed is scarce. Therefore, in order to obtain high benefits in spring chicken raising, the following must be done:
Keeping Warm The climate in early spring is cold and changeable, which brings a lot of inconvenience to the production of chickens, especially the effect of low temperature on laying hens is very obvious. Therefore, under normal circumstances, you can properly increase the stocking density, close the doors and windows, add grass curtains, drink warm water, and heat the stove to keep the temperature of the chicken house at 3℃~5℃.
Ventilation In early spring, due to the low temperature, the doors and windows of the chicken house are closed tightly, and the ventilation is reduced. However, the exhaust gas from chickens and the ammonia, carbon dioxide, hydrogen sulfide and other harmful gases produced by the fermentation of chicken manure will accumulate in the chicken house, which is easy to induce chickens. Respiratory tract and other diseases. Therefore, to raise chickens in early spring, it is necessary to deal with the relationship between ventilation and warmth, remove the feces and debris in the chicken house in time, and ensure that the air in the chicken house is fresh. 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.
In the early 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 number of water droplets when it comes into contact with the cold roof and walls, causing excessive humidity in the chicken house and proliferation of bacteria and parasites. Created the conditions. Therefore, in early spring, we must strengthen management, pay attention to keeping the chicken coop clean and dry, repair the damaged sink in time, avoid overfilling when adding water, and it is strictly forbidden to splash water on the floor of the house.
Disinfection and disinfection should run through the entire process of raising chickens. In early spring, the temperature is low and the frequency of bacterial activity decreases, but the climate is still colder at this time, 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, it is necessary to do a good job of disinfection and disinfect regularly.
Supplemental illumination is the driving force of all life activities. In early spring, days are still short and nights are long, and laying hens often drop in laying 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 chickens). For example, the natural light during the day is 12 hours, and artificial supplementary light is required for 2 to 5 hours every day.
Energized chickens rely on energy feed into the body to obtain heat energy to maintain body temperature. The lower the outside temperature, the more heat energy the chicken uses to keep out the cold. According to measurements, the feed consumption of winter and spring chickens is about 10% higher than that of other seasons. Therefore, sufficient energy feed must be ensured in the feed of early 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.
The resistance of strong early spring chickens is reduced, so special attention should be paid to epidemic prevention and disease prevention and regular vaccination. 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.
