Autumn and winter are the harvest season for farmers, and it is also an eventful event for the Dehua black chickens. Many diseases occur easily this season. This requires farmers to do a better and better job in feeding management and disease prevention and control. Mainly pay attention:
First, cold insulation
1, repair the chicken house in advance. Check whether the house and its windows are windproof and leakproof. If any, repair it immediately to prevent the thieves from invading.
2, enhance adaptability. Although the temperature has declined during the late autumn and early winter, it is better to keep some windows with higher position while maintaining good insulation, so as to facilitate ventilation and reduce the room temperature appropriately so as to adapt to the low temperature in winter.
3, buy insulation equipment. We must do a good job of warming and keeping warm the chicken coops, remove the chicken droppings in time, change the litter, and keep the coops clean and dry. The chick houses can be heated and heated with infrared heat lamps.
Second, properly improve the feed energy
In order to withstand cold and heat consumption, winter chickens can increase the feed energy level by 10% and increase the proportion of energy feeding such as corn, rice bran, and oils and fats.
Third, increase lighting
The natural winter illumination time is short and cannot meet the production needs of laying chickens. It takes 16-17 hours to make up.
Fourth, ventilation
While keeping warm and cold, pay attention to proper ventilation. Practice has proved that blindly keeping warm and not properly ventilated, the pungent taste of the chicken house has a much greater impact than a certain range of low temperatures.
V. Do a good job of epidemic prevention
It is necessary to take precautions and combine prevention and control to vaccinate regularly. Regular disinfection of sheds, utensils, and drinking water, and do a good job of preventive medications, can add multidimensional elements to reduce cold stress. At the same time, the chickens were carefully observed every day, and the diseased chickens were found as early as possible, isolated and treated.
