Breeding broilers beware of anoxia measures in winter
1. Strengthen ventilation in the house
When the air in the henhouse is fresh, the chicken grows fast and develops well. As chickens breathe twice as much gas as mammals, they need more oxygen. Only by strengthening ventilation in the henhouse can we ensure that chickens have enough fresh air. It is usually ventilated every 2-3 hours, 20-30 minutes each time. Raise the house temperature before ventilation, and pay attention to do not let the wind blow directly to the chicken body during ventilation, in order to prevent the chicken from getting sick.
2. Control the feeding density.
Broilers are generally raised in large groups, with high density and large quantity, which can easily lead to lack of oxygen and increase of carbon dioxide in the air. Especially when the chicks are raised at high temperature and humidity, the lack of fresh air for a long time will often lead to weakness and sickness of chicks and increase the rate of dead chickens. In henhouses with high breeding density, the chance of airborne diseases increases, especially when the content of ammonia is high, respiratory tract diseases are often induced. Therefore, to control the feeding density, 9 chickens weighing about 1.5 kilograms per square meter can be doubled if raised online.
3. Pay attention to the method of heat preservation
Some farms only emphasize heat preservation while ignoring ventilation, resulting in serious hypoxia in chicken sheds. Especially in the house with coal stove heat preservation, the stove sometimes run smoke or pour smoke, it is more likely to cause gas poisoning, even if the normal heating will compete with the chicken for oxygen. Therefore, it is best to build the stove in the doorway outside the house to effectively avoid the harm of harmful gases.
4. Prevent stress
Chickens are nervous and timid, and the sudden appearance of any new sounds, colors, unfamiliar movements and objects will cause chicken unease, cry, surprise, fry, etc., these stresses will consume a lot of physical energy and increase the oxygen consumption of chickens. it is more harmful to the growth, development and weight gain of chickens. Therefore, it is necessary to keep the chickens quiet and stable in order to reduce the losses caused by various stresses.

Health and epidemic prevention of white-feathered broilers during brooding
Chicks have weak physique and poor ability to resist pathogenic microorganisms. once any disease occurs, it is difficult to control, which will not only control the development of the disease, but also cause irreparable losses to the future production. Therefore, in order to do a good job in health and epidemic prevention during the brooding period, we must prevent

How to make native chickens lay more eggs in winter
The egg production of native chicken is low or even stopped in winter. How can we increase the egg production of native chickens? Now some key points are introduced as follows: first, add thermal insulation and lighting facilities to cover the wind barrier around the chicken house, keep the floor clean, spread the grass and put the door at the same time.
