Chicks are susceptible to disease in spring, especially those within 3 months of age, which are more likely to get sick and die. Therefore, the brooding management during this period should be careful to prevent hypoxia.
1. Hypoxia performance
The hypoxic chicks were depressed, screamed, breathed, panted, stretched their necks and shakes their heads, refused to eat or drink, their beaks turned blue, and in severe cases, their skin became cyanotic, their feet turned blue, and finally fell to the ground and died.
2. Causes of hypoxia
1. During the brooding stage, many farmers are worried that the low temperature will cause the chicks to catch a cold or other diseases. They often increase the stocking density to increase the temperature of the house, resulting in a lack of oxygen in the house.
2. Burning wood, charcoal, coal, etc. in the brooding house for heating. These fuels not only consume a lot of oxygen when burned, but also release a lot of harmful gases such as carbon monoxide and sulfur dioxide.
3. During brooding, many farmers worry that the temperature in the brooding house will be affected when the litter and excrement of the chickens are removed, so they reduce the number of replacements, so that it will ferment and generate a lot of harmful gases such as ammonia and hydrogen sulfide, which will lead to the brooding house. Internal hypoxia.
3. Preventive measures
First, we must expand the brooding area in due course. In spring brooding, a “house in house” should be built in the chicken coop. And the brooding room should appropriately expand the brooding area according to the age of the chicks.
Second, choose a suitable heat source. When brooding chicks, avoid directly burning fuels such as firewood, coal, charcoal, etc., and use power sources, or use kang heat preservation methods for heat preservation. As the brooding room lighting, electric lights can be used, but it is best to use Kangdao for heating and keeping warm.
Third, we must reasonably resolve the contradiction between heat preservation and ventilation. If there are more water droplets on the top and around the brooding room made of plastic film, it can be judged that the indoor humidity is relatively high; if the plastic film has no water droplets, the humidity is correspondingly reasonable. If a person enters the brooding room and does not smell the odor and does not feel depressed and depressed, the air is fresher and more oxygen. On the contrary, the air is dirty and the oxygen is insufficient.
When the humidity is too high or the air is too dirty, the chicken breeder should open the gap at the top of the brooding room and near the ground to achieve the purpose of ventilation. There are more chickens, the air is dirty, the humidity is high, and the temperature is high, the gap can be larger and the time should be longer, otherwise it should be smaller and shorter. It must be noted that you must never let the chicks catch cold and get sick. It is better to ventilate in this way multiple times a day than to ventilate thoroughly at once.
Fourth, clean and replace litter and excrement in time. When removing litter and excrement, do not uncover all the obstructions. Instead, choose a sunny day and a high temperature time, and quickly put back new litter.
Fifth, spray oxygenation drugs. Peracetic acid is a broad-spectrum high-efficiency chemical disinfectant that is unstable in nature but can release oxygen and acetic acid. It can be sprayed in the chicken house for disinfection in time to neutralize some harmful alkaline gases.
