In order to raise broilers, a good breeding environment is essential. In battery cage for broilers, temperature, humidity, ventilation, light, and density are important links and are the basic points.
Because the chicks are relatively small, many abilities are not yet available, such as regulating body temperature, which requires artificial, such as chickens piled up, too far away and close to the heat source are abnormal temperature performance. It is necessary to manually solve the temperature of the house. When the temperature is suitable, the chicks are evenly distributed and the activities are normal. Humidity is the water content in the air, and proper humidity is closely related to the normal development of the chicken. Humidity is large, the house is damp, the litter is mildewed, the bacteria breeds fast, the chicken is easy to get E. coli, coccidia, mold and other diseases; the humidity is small, the house is dry and dusty, and the chicken is prone to respiratory diseases. During the brooding period (the first 3 weeks), the relative humidity is controlled at 65% to 70%. During this period, the air is easy to dry due to the high temperature, and it is necessary to prevent the chicks from dehydrating due to low humidity.
The house should be ventilated frequently, so that the house is clean and the fresh air is exchanged to promote the rapid growth of the chicken. The harmful gases in the house are mainly ammonia, hydrogen sulfide, carbon monoxide, carbon dioxide and so on. It is easy to cause chickens to get sick. Controlling the light is mainly to control the illumination time and light intensity. There are two characteristics of broiler illumination: 1 The illumination time should be as long as possible, which is the need to prolong the feeding time of the chicken, adapt to rapid growth, and shorten the growth cycle. 2 The light intensity should be as weak as possible, in order to reduce the excitement and movement of the chicken and improve the feed efficiency.
The brooding density refers to the number of chicks fed per square meter of the house. Appropriate stocking density can ensure the normal growth and development of chicks. The breeding density is too large, the chicks are crowded and piled up, the growth is slow, the development is not neat, the environmental pollution is aggravated, the disease spreads quickly, and the mortality rate is high. The density is too small, which is not conducive to heat preservation, resulting in waste of feeding area, energy, labor and so on. The feeding density of broilers should be flexibly controlled according to the specific conditions of the structure, poultry farming cage equipment,ventilation and feeding conditions of the house.
