In winter and spring, the issue of brooding and heat preservation has always been highly valued by people. The lack of oxygen is easily overlooked, resulting in frequent loss or even failure. According to the occurrence of hypoxia symptoms and causes, in order to prevent the brood chamber hypoxia, so as not to affect the growth of chicks and threaten the life safety of young birds, the following measures can be taken. To expand the brooding area in a timely manner To brood in winter and spring, it is necessary to build a “house in house†brooding room in a poultry house in order to stabilize the temperature and meet the insulation requirements. In order to save energy and facilitate management, the scope of brooding should be reduced at the beginning. However, as the chicks grow faster, they consume more oxygen. Therefore, the construction of "house in the house" brooding room should be based on the chick's age appropriate to expand the brooding area, in order to expand the scope of incubation and oxygen content. Try to avoid high density, small area and prone to hypoxia. Select suitable heat source for heat to avoid certain heat source and young birds competing for oxygen, while avoiding the release of harmful gases and fumes when certain heat sources burn during heat production, and avoid naked fire such as firewood, coal and charcoal during brooding and heating. Direct combustion of fuel, but should use the power, or the use of ramp insulation form of heat insulation. Such as brooding room lighting, you can use electric lights, but as a heating, warmth is best to squat, the first advantage is to avoid the light when the lamp is too strong and affect the chick's rest and growth; Second, the ramp insulation can make the brooding room The ground is warm and dry, which is conducive to protecting the chicks' abdomen from cold attacks, which is conducive to growth and reduction of the incidence. Third, because the ramps can be heated outside of the ramps, they can be set outdoors, even when there is no firewood, coal or charcoal. The contradiction of young birds fighting for oxygen; Fourth, there is no harmful gas and smoke released from burning firewood, coal and charcoal, which endangers the growth and safety of young birds; Fifth, the temperature of the brooder room is relatively low due to the insulation of the ramps. Small, litter and chicken excrement are not easy to ferment, thereby reducing harmful gases and oxygen consumption. Maintain cleanliness and timely replacement of litter and excrement. The fermentation of litter and excrements at a certain humidity and temperature will consume part of the oxygen in the brood chamber and will discharge gases that are toxic to the growth and safety of the chicks. In order to prevent and reduce the occurrence of this phenomenon, timely replacement of litter and excrement is an effective method to reduce and prevent the lack of oxygen in the brooding room. When removing litter and excrement, do not open it completely. Insulation barricades, but also should choose sunny days, high temperatures, and to quickly back into the new litter. Appropriate spraying of oxygenated medicines to prevent oxygen deficiency in the brooding room, if pure oxygen is used, one is costly and costly, and the second is more troublesome work. Peracetic acid is a broad-spectrum and highly efficient chemical disinfectant that is unstable but can release oxygen and acetic acid. According to this characteristic, timely spraying of an appropriate amount of peracetic acid in the house can increase oxygen, secondly it can disinfect poultry houses, and neutralize some harmful alkaline gases. Appropriate insulation and reasonable ventilation to solve the contradiction between insulation and ventilation. Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light.
