In the winter and spring season, the house has little ventilation, and there are often harmful gases such as hydrogen sulfide, ammonia, and carbon monoxide. These gases can severely contaminate the environment of the house and cause the disease and even death of the flock. The prevention measures are as follows. *QLI3B9V
1. Rationally design the diet to prepare the full-price diet according to the nutritional requirements of the chicken to avoid the lack or surplus of nutrients in the diet. Special attention should be paid to the fact that the crude protein level in the diet should not be too high, otherwise it will cause excess supply and discharge. More nitrogen. The addition of enzyme preparations to the feed can increase the utilization of feed protein and reduce the excretion of nitrogen in the feces, thereby improving the air quality in the house and saving feed. According to experiments, adding 1% to 2% of charcoal slag in the chicken diet can make the feces dry and reduce the odor; adding 2% to 5% of zeolite powder can reduce the moisture content and odor of the feces, and it is beneficial to improve Feed utilization rate.

2, do a good job ventilation and ventilation in winter not only pay attention to cold insulation, but also appropriate ventilation. When using coal for brooding, avoid closing doors and windows for a long time to prevent poor ventilation. The heating furnace must have a smoke exhaust pipe leading to the outside, and check whether the exhaust pipe is tightly connected and unblocked during use. When fumigation with formaldehyde is used to sterilize the chicken house, the dosage and time must be strictly controlled. After fumigation is completed, the air is changed in time, and the odor is reduced and then transferred to the flock. =>M^02"
3, control the humidity of the chicken house when the humidity is too large, you can regularly open the window to make the air circulation, or put some large amount of lime in the ground to absorb the moisture in the air, immediately after the lime is wet, you can also use cinder for padding, Adsorption of toxic and harmful gases. {buo^kgj`]
4. Clean the environment of the shed 1. Remove feces and litter in the house in time to prevent large amounts of ammonia from leaving for a long time. Under normal circumstances, usually 1 to 2 days to clear 1 times, chicken disease should be cleared once a day. 2 Use appropriate amounts of equal parts of Artemisia, Atractylodes, Daqingye or garlic stalks to burn in the house, both sterilizing and deodorizing, especially when empty. 3 Charcoal, activated charcoal, coal cinder, quicklime, etc. have a strong adsorption effect. These materials can be loaded into net bags and hung in the chicken house or sprinkled on the ground to absorb odors in the air. 4 Mixing 2.5kg of sulfur into every 10m2 of litter can inhibit the generation and distribution of ammonia gas. 5 Weigh 350g of superphosphate per 50 chickens on the ground to reduce the amount of ammonia in the air. The effective period is 6 to 7 days. 6 Use 7 parts of ferrous sulfate and 3 parts of dry coal ash, and mix it with 10% of the weight of the chicken droppings into the house. Once a week, remove ammonia and hydrogen sulfide gas from the house. 7 Hydrogen peroxide, potassium permanganate, copper sulphate, acetic acid, etc. have an odor suppressing effect. Pad litter with 2% benzoic acid or 2% acetic acid, or use 4% copper sulphate and appropriate amount of slaked lime to pave the ground in the litter. Can reduce the odor of the chicken house. kP-3"ACG
