In winter, many laying hens often suffer from problems such as decreased egg production rate and more diseases, causing economic losses to farmers. How to make chickens in a good production environment and maintain high yields and stable production, specific management measures are as follows:
First, add artificial lighting in time. The method of turning on the lights early in the morning and turning off the lights in the evening can be used to stabilize the lighting time of the layer chickens every day for 16 hours.
Second, strengthen the insulation and prevent thieves from invading. In winter, the temperature is low, and the chicken house should be kept cold and warm. Cover the doors and windows with plastic sheeting to plug the walls and prevent the thief from blowing the chicken body. In winter, it is forbidden to drink iced water.
Third, pay attention to ventilation, to avoid excessive gas. Most chicken farmers only pay attention to the closed insulation of the chicken house in winter, but they neglect the ventilation and ventilation, causing excessive accumulation of harmful gases such as ammonia gas, carbon dioxide, and hydrogen sulfide in the house, which will seriously affect the production performance of the layer chicken. Therefore, in the strengthening of insulation, we must pay attention to ventilation and ventilation, according to the size of the chicken density, temperature, weather, wind, the size of the stimulation of harmful gases and other factors to determine the length of the window, the number of times.
Fourth, increase the number of feeding and increase feed intake. In winter, the temperature is low, and the layer must absorb enough nutrients from the feed to resist the cold to ensure its normal metabolic activity and maintain its high-yield performance. In winter, it is better to increase the number of feedings to promote the multi-feeding of laying hens. It is better to eat before turning off the lights.
Fifth, adjust the feed formula, increase energy feed and vitamin A, vitamin D dosage. The winter seasoning of the production of eggs can be properly increased energy levels in the feed, in addition to increase the amount of vitamins in the feed, to increase the egg laying rate has a significant effect. Experiments have shown that increasing vitamin A and vitamin D in feed during the winter can increase egg production by 3.5%.
Sixth, strengthen feeding management and reduce stress. Egg-laying chickens are timid, vulnerable to fright, sensitive to the surrounding environment, slightly uncomfortable, and affect feed intake, egg production rate, and cause death.
Seventh, strengthen disease prevention and treatment. In winter, the climate is dry, the interior is closed and the doors and windows are closed tightly, the harmful gases are relatively increased, and the pathogenic microorganisms live for a long time under low temperature conditions. These factors easily make the chicken outbreak of respiratory diseases, and should be effectively strengthened and prevented every 3-5 days. Disinfect the chicken with a disinfectant such as 100% poison; test the Newcastle disease antibody regularly; if the surrounding environment is found, it should be immediately prevented with the corresponding drug.
