Spring is the golden season for brooding. However, in spring, the temperature is low, the temperature is changeable, and chicks are prone to lack of oxygen. Especially for chicks within 3 months of age, they are more likely to die of oxygen deprivation. Therefore, the management of brooding during this period must be meticulous.
The hypoxic chicks started as depressed, screaming, breathing, panting, neck throws, reluctant to feed, stopped drinking, bursting blue hair, severe skin cyanosis, blue feet, and finally fell to the ground. death. The following measures should be taken:
1. Expand the area of ​​young houses in a timely manner. In the spring brooding period, brood chambers in the "house in house" should be built in the chicken house, and according to the age of the chicks, the area of ​​the chicks should be appropriately enlarged to expand the scope of the breeding and the amount of oxygen.
2. Select a suitable heat source. When brooding is warmed, it should try to avoid choosing fuels such as firewood, coal, charcoal, and wood fires that are directly burned by open flames. Power should be used, or heating should be done using tunnel heating. As a brooding room lighting, electric lights can be used, but as a heating and warmth, it is best to use a ramp to prevent the light from being too strong and affect the rest and growth of the chicks. Insulation on the ramp can warm and dry the floor of the brooding room, reduce the humidity in the brooding room, and make it difficult for the litter and chicken excrement to ferment, thereby reducing harmful gases and oxygen consumption.
3. A reasonable solution to the contradiction between insulation and ventilation. If there are more water droplets on the top and around the brooding chamber where the plastic film is formed, the humidity in the room can be judged to be large; if the plastic film does not contain beads, the humidity is reasonably reasonable. If a person enters the brooding room and smells no smell and feels depressed and depressed, the air is relatively fresh. On the contrary, the air is dirty and oxygen is insufficient. When the humidity is too high or the air is too dirty, the chicken farmer should open the gap at the top of the brooding room and near the ground to achieve the purpose of ventilation. More chickens, air pollution, high humidity, high temperature gaps can be larger, longer time, otherwise it should be smaller, shorter. It must be noted that the chicks must not be affected by cold, and it is possible to take several changes of air every day, but not to completely change the air at a time.
4. Change litter and excrement timely. When removing litter and excreta, do not uncover all the coverings used for insulation. Also, choose a sunny day and a warmer time, and quickly replace the new litter.
5. Spray oxygenation drugs. Peracetic acid is a broad-spectrum and highly efficient chemical disinfectant that is unstable in nature but can release oxygen and acetic acid. Spraying peroxyacetic acid in a chicken house in time can increase oxygen and disinfect the house to neutralize some of the harmful alkalis. Sex gas.
