Increase the heat insulation layer of the house
If the roof of the chicken house and the northern wall are found frosted, the ceiling of the insulation layer should be increased. The insulation layer can be increased with plastic sheets or linoleum paper to block the north window. Wind barriers can also be provided to ease the cold wind in the proper place of the main wind from the house. The optimum temperature for laying eggs is 18 to 23 degrees Celsius, and the ideal temperature is 21 degrees Celsius. If it is less than 13 degrees Celsius, the egg production of the breeder will decrease; if it is lower than 12 degrees Celsius, the growth and development of the broiler will be severely hindered. When the temperature is low, the fan speed can be reduced, reducing air circulation.
According to the temperature appropriate adjustment of feeding amount
In the same condition, the energy requirement is different under different temperatures. In winter and spring season, broiler breeders can feed 150-170 grams of feed each day, so that the feed heat energy can be increased by 12.1 to 12.3 MJ, which can meet the needs of low-temperature thermal energy. In the event of a cold spell, the temperature dropped abruptly, and the chickens themselves could not adjust the feed intake all at once. It would have a great reaction. Therefore, we should pay attention to the weather forecast at any time, and add 10 to 20 grams of feed to each chicken 1 to 2 days before the onset of the cold current. For 3 to 5 days, the chickens can get 112.8 to 142.1 Mg of heat in order to maintain body temperature. Egg production level. For every 3 degrees Celsius drop in temperature, 5 grams should be added. After the cold weather passed and the temperature rose, it returned to the original amount of feed. At the same time pay special attention to the quality and quantity of various amino acids.
Increase the proportion of dietary energy in the feed and appropriately reduce the protein content.
In addition, a certain gas flow rate (0.1 to 0.2 m/s) should be maintained in the winter and spring chicken houses so that the concentration of ammonia in the house does not exceed 200 mg/kg, hydrogen sulfide does not exceed 10 mg/kg, and carbon dioxide does not exceed 0.5. %, to meet the chicken house health standards. Many farmers in winter and spring in order to keep warm, the sheds often close the windows and close the doors tightly, resulting in air pollution, humidity, and dull mats; ammonia, hydrogen sulfide, carbon dioxide, methane and fecal odor on the feathers of chickens Disadvantages of the feet and feet, severe respiratory diseases, ascites in broilers, etc. may occur.
