Management scheme of chicken farm in winter

Protect against cold and keep warm

The cold and changeable climate in winter brings a lot of inconvenience to chicken production, especially the effect of low temperature on laying hens is very obvious. Proper increase of feeding density, closing doors and windows, adding straw curtain, drinking warm water and stove heating can be adopted to keep the temperature of the chicken house between 3 ℃ and 5 ℃.

Moderate ventilation

In winter, due to the low temperature, the doors and windows of the chicken house are closed strictly and the ventilation is reduced, but the exhaust gas from chicken and the harmful gases such as ammonia, carbon dioxide and hydrogen sulfide produced by chicken manure fermentation still exist, which is easy to induce respiratory diseases of chickens. Therefore, it is necessary to deal with the relationship between ventilation and warmth, and remove the feces and sundries in the chicken coop in time. When the weather is better at noon, windows should be opened for ventilation to make the air in the house fresh and oxygen sufficient.

Reduce moisture

In winter, the ventilation in the chicken house is small, the water evaporation is reduced, and 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, resulting in excessive moisture in the chicken house, creating conditions for the proliferation of bacteria and parasites. Therefore, we must strengthen management, pay attention to keep the chicken coop clean and dry, repair the damaged sink in time, do not add too much water, and it is strictly forbidden to splash water on the floor of the house.

Regular disinfection

Disinfection should run through the whole process of raising chickens. When the temperature is low in winter, the activity frequency of bacteria decreases. However, the resistance of chickens is generally weakened because of the cold climate in winter. If disinfection is neglected, it can easily lead to an outbreak of disease.

Supplementary lighting

In winter, the night is long and the day is short, the laying rate of laying hens will decrease due to lack of light. In order to overcome this natural defect, artificial lighting can be used to make up for it. Under normal circumstances, the total amount of light per day should not be less than 14 hours, nor more than 17 hours. For example, if the natural light is 12 hours during the day, artificial supplementary light is needed for 2-5 hours a day.

Increase energy

The chicken maintains its body temperature by getting heat from the feed it eats into the body. the lower the outside temperature, the more heat the chicken consumes to protect against the cold. It is determined that the feed consumption of chickens in winter is 10% higher than that in other seasons. Therefore, sufficient energy must be ensured in the feed of chickens in winter. in addition to ensuring a certain proportion of protein, high-energy feed with more starch and sugar should be appropriately added to meet the physiological and production needs of chickens.

Strengthen one's physique

As the resistance of chickens decreases in winter, special attention should be paid to the work of epidemic prevention and vaccination on a regular basis. According to the actual situation, some preventive drugs can also be fed regularly to appropriately increase the content of vitamins and trace elements in feed.
