The cold season is the most unpleasant season for poultry, and it is also the season when the most cost-effectiveness of livestock and poultry is affected. Because the temperature is low and the temperature difference is very large, it affects the growth rate of the birds. Therefore, it is necessary to strengthen the feeding and management work in the cold season. On November 17, the reporter interviewed Wang Jingyu, an assistant professor of the College of Animal Science and Technology at the Northwest Agriculture and Forestry University, about how to manage chickens in the cold season. He was asked to support the farmers.
Controlling air quality Wang Jingqi stated that the air quality in the breeding environment is a factor that cannot be ignored. Especially in the cold season in winter, heat preservation and ventilation are the biggest contradictions in the winter culture environment. Attention is paid to heat preservation and ventilation is neglected. This can easily cause air pollution in the house, increase pathogenic microorganisms, and lead to diseases such as respiratory tract. He suggested that farmers should increase their ventilation and ventilation while keeping warm, and the temperature difference between day and night should not exceed 5°C. At the same time, adding "Fuyijian" to improve the digestibility of feed, reduce nitrogen emissions, but also timely cleaning of excrement.
Concerned about the quality of drinking water In addition to air quality, farmers also need to pay attention to the quality of water in the cold season. It is possible to add “Love Sour Po†through drinking water to inhibit the proliferation of pathogens, which will help increase the proliferation of probiotics and the activity of digestive enzymes, increase the feed conversion rate, promote the growth of chickens, and maximize the production potential. Wang Jingyu reminds farmers that it is best to give chickens about 20°C warm water to prevent indigestion, diarrhea and even miscarriage caused by chickens drinking water.
In winter, due to the need for control of body temperature of livestock and poultry, the increase of body heat increases, the energy consumption required increases, and the proportion of energy feed required increases. Among them, the feed protein of laying hens can be 15%-15.5%, relatively increase the proportion of energy feed, the metabolic energy can be no less than 2700 kcal/kg, and the egg energy can be between 55% and 60%. Wang Jingqi said that adding 0.5% to 1% of fat to the whole price of layer chicken can not only reduce the energy supply, but also improve feed palatability, reduce dust, help resist cold, increase feed repayment, and improve eggshell quality. . In addition, the temperature difference in winter has changed greatly, the disease has been rampant, the stress of chickens has been increased, and the immune pressure has increased. Farmers can add "Fuweida" anti-stress effect enhancer to the feed, which will help improve the chicken's constitution and improve immunity. And anti-stress ability to reduce disease occurrence.
