When the farmers are raising brooding, the humidity in the house and the freshness of the indoor air have a great influence on the growth of the chicks. The density of the brooding of the farmers is also closely related to the development of the brooding, so the farmers should How to control humidity and density and stick to the fresh air in the room.
First, the appropriate humidity: Although the impact on the growth of chicks is not so serious, but it is not neglected. The most suitable relative humidity of the brooding room is 60-70% (1-10 days old), 50-60% after 10 days of ridge. The high humidity of the early brooding is mainly due to the drinking water of the chicken, the small feed intake, and the defecation. Less, the reason why the environment is relatively dry. Only the relative humidity is raised, which is beneficial to the growth and development of the chicken. Otherwise, when the humidity is too low (as low as 17%), the water in the chicks is largely emitted, and dehydration occurs. Drying together with the air causes the dust in the room to fly, affecting the respiratory tract and causing disease. Therefore, the indoor relative humidity of the chicks must be maintained at 60-70% in the first 10 days.
2. Reasonable density: The density is closely related to the growth and development of the chicks. The density is too large, the chickens are crowded, the food is uneven, the chicks grow slowly, the development is not neat, the disease is easy to be infected and the stagnation occurs, the death rate is added, and the density is small. Economic waste. The density of chick breeding should be flexibly controlled according to the structure of the house, the size of the brooder, and the conditions of ventilation and breeding. The appropriate density can be found in the picture at the bottom of the article.
The density of the breeding should be adjusted continuously with the age of the chicks. The strong and weak chicks should be grouped frequently, and the weak chicks should be cultured in the upper cage. When considering the breeding density of chicks, it is necessary to pay attention to the size of the chickens. The chicken farms in the commercial chicken farms can be larger than the chicken farms, with hundreds of small groups and thousands of large groups. Conditional chicken farms can be grouped at any time, and male and female chicks are best separated and cultured.
Third, the indoor air is fresh: in the brooding room, it is necessary to open the doors and windows regularly, discharge the indoor dirty gas, change into the fresh air, together with the ventilation, also adjust the indoor temperature and humidity. The chicks grow fast, have a high body temperature, and breathe fast. They are new and vigorous, and the carbon dioxide and harmful substances emitted are more than twice as high as those of large livestock. If you do not ventilate frequently, it will seriously affect the healthy growth of the chicks and even cause death. The ventilation of the open brooding room is mainly based on opening and closing windows and using natural ventilation to ventilate. Install the exhaust fan in winter. The closed brooding room ventilation mainly adopts the power ventilation method. The ventilation amount is 0.03-0.06 m/min in winter and 0.12 m/min in summer. It is suitable for people to enter the chicken house without suffocation, nose, and eye-catching.
