For the breeding of broiler chickens, most of the farmers now use three-dimensional broiler cages for breeding. The use of three-dimensional broiler cage culture is more conducive to the management of the chickens by the farmers, and is more conducive to the rapid growth of the chickens. However, if the farmers do not use scientific and reasonable farming methods to raise the flocks, then the flocks are difficult to grow. Today, we will make a detailed account of the major feeding points that farmers should pay attention to when raising chickens in broiler cages.
1. Adopting a phased expansion of cages, that is, brooding in a small area 21 days before the feeding period, saving heating costs, and gradually expanding after 21 days.
2. According to the nutritional needs of caged broilers, study and design the corresponding feed formula to meet the needs of growth and development under high-density cage conditions. The vitamins in the feed formula are increased by an average of 20% over the ground level, which is suitable for caged broilers.
3. The lower part of the front cage of the chicken cage during the brooding period is designed as a “pear shape”, which is adapted to the feeding needs of the commercial broiler by adjusting the baffle.
4. The caged broiler house must be a fully enclosed chicken house without a window. The exhaust fan will exhaust the air inside the house, and the fresh air will enter the house through the air inlet. Artificial lighting is used in the house instead of natural light. When the temperature is high, the house should be equipped with a wet curtain to cool down, and in the cold season, artificial heating or the use of the chicken’s own heat can be used to keep the temperature inside the house within the comfort range.
5. Improve the material and structure of the cage bottom, so that the incidence of chest cysts in broilers is greatly reduced, and the incidence of thoracic cysts is less than 7.5%.
6. Battery broiler cages are used to raise large-scale commercial broiler chickens, that is, from the first day of brooding until the slaughter, they are kept in cages to increase the stocking density, maximize the chicken house and land utilization rate, and at the same time facilitate feeding and management.
