With the popularization of battery cages for poultry farming equipment, intensive poultry breeding has become more and more popular. Because the chicken house is semi closed or totally closed, it is easy to produce many harmful gases in the chicken house. If measures are not taken, serious consequences will result.
What harmful gases will appear in the chicken house?
- Ammonia gas: The feces will produce ammonia after decomposing nitrogenous organic substances through bacterial fermentation. It is highly irritating, especially the mucous membrane. It often causes congestion and edema of the mucous membrane of the chicken conjunctiva and upper respiratory tract, and has adverse effects on the growth and development of chickens and egg laying.
- Hydrogen sulfide: Sulfur containing organic substances in feces are produced by bacterial decomposition. Its irritation is no less than ammonia, and it can also cause keratitis, conjunctivitis, and irritation of respiratory mucosa. In severe cases, it may cause respiratory center paralysis and death. Chronic stimulation for a long time reduced the chicken’s physique and production performance.
- Carbon dioxide: It is mainly excreted by the respiration of chickens after metabolism. The space of the chicken house is narrow, the feeding density is too high, and when the ventilation is poor, the carbon dioxide concentration in the house will be too high, and the chickens will suffocate and die.
- Carbon monoxide: In early spring, the temperature in the chicken house was low, the coal fire was not properly managed, the coal was not completely burned, the chicken house was poorly ventilated, and the lack of oxygen in the chicken house was mostly caused by gas poisoning, and a large number of chickens died in serious cases.
- Methane: The feces are fermented in the intestinal tract, and the feces are discharged and accumulated in the chicken house for a long time. Methane gas can also cause severe irritation to chickens.
- Formaldehyde: The incomplete residual gas is discharged when the chicken house is fumigated with formaldehyde. If the concentration is too high, it will also cause eye and respiratory diseases
How to maintain the environment of the chicken house?
And many farmers will choose a closed chicken house when constructing chicken farms and chicken battery cages. It is important to know that this type of chicken house is prone to produce harmful gases because of the closed environment.
When purchasing battery cage for poultry plant equipment. Choose a fan for reasonable ventilation, after all, the closed chicken house windows are very small. Therefore, farmers need to purchase mechanized equipment for ventilation. Reasonable ventilation can remove harmful gases from the chicken house, let fresh air enter the chicken house, and give the chicken a good growth and production environment.
There is also daily environmental sanitation: chickens produce a lot of manure and residual feed, dust and other garbage every day. Farmers need to clean up in time, do not clean up after a lot of accumulation, especially in summer, high temperature and humidity are easy The garbage is spoiled and harmful gas is produced, which will affect the health of chickens.
Controlling the breeding density: the use of chicken cages to raise the chickens itself has a high breeding density, and farmers cannot increase the number of chickens at will. If the breeding density in the chicken house is too high, it will affect the activities of the chickens, heat dissipation, eating and drinking, etc. Therefore, it is necessary to strictly follow the density required by breeding management, otherwise it will bring many diseases caused by excessive density, and will also lead to poor air quality in the chicken house.
Farmers can add enzyme preparations to the feed of the chickens when feeding, which can improve protein utilization, reduce the conversion of protein to nitrogen and amines, reduce the nitrogen content in manure, improve the air in the chicken house, and save cost.
Control measures for harmful gas
- Reasonable construction of chicken house: the chicken house must be built in a place with dry terrain, convenient drainage and good ventilation. Enough air vents shall be reserved on the side walls or top of the chicken house to ensure that harmful gases can be eliminated in time. The chicken house should have a concrete floor to facilitate cleaning and disinfection.
- Keep clean and dry: keep the inside and around the chicken house clean and dry. The chicken house is required to be clean and dry. The feces in the chicken house should be removed immediately to prevent a large amount of harmful gas from being generated when staying in the chicken house for a long time. When the cushion is used for leveling, the cushion shall not be affected with damp, or it shall be replaced in time. Prevent sewage and feces from accumulating around the chicken house to minimize the source of harmful gas.
- Greening around the chicken house: use green plants to absorb the carbon dioxide emitted by chickens, purify the environment around the chicken house, and create a good chicken production climate.
- Control the density of chickens: the feeding density in the chicken house shall not be too large. At ordinary times, 30 rabbits aged 1-2 weeks, 25 rabbits aged 3-4 weeks, 12 rabbits aged 5-8 weeks, 8 rabbits aged 9-18 weeks, and 6 rabbits aged 19 weeks were fed per square meter. When raising in cages, it should be noted that the cages in the house should not be too crowded, and the number of chickens in each cage should not exceed the standard.
- Optimize the diet structure: adjust the full price diet according to the nutrition needs of chickens to avoid insufficient, insufficient or excessive nutrients in the diet. Pay special attention to the level of crude protein in the diet should not be too high. Otherwise, protein digestion is incomplete and excessive nitrogen is produced. At the same time, the feed amount shall be appropriately increased or decreased according to the feed intake of chickens to prevent the long-term residue of feed in the trough from mildewing.
The above is the introduction to farmers in the process of raising chickens in chicken cages, and some technical points to reduce harmful gases in the chicken house. I hope that the above description can bring advantages to farmers and create a healthy and comfortable growth and production for the chickens. The environment makes it play a better growth and production performance.
