Cages are used for breeding broilers for several reasons:

1. Improve breeding density: Cage breeding can effectively use space and improve the breeding density of broilers, thereby increasing the number of breeding and improving breeding efficiency.
2. Easy management: cage farming makes broilers live in a relatively fixed environment, which is conducive to farmers’ unified management and care of broilers, including feeding, drinking water, epidemic prevention and so on.
3. Reduce disease transmission: Cage farming can effectively isolate broilers, reduce the risk of disease transmission, reduce the death of broilers, and improve the success rate of breeding.
4. Improve growth rate and meat quality: cage culture can provide a good growth environment for broilers, which is conducive to the full play of growth potential of broilers, improve growth rate and meat quality.
5. Save feed and energy: Cage farming can reduce fighting and waste between broilers, so that feed is used more efficiently. At the same time, cage culture is beneficial to heat preservation and reduce energy consumption.
6. Reduce environmental pollution: Cage farming can easily carry out manure treatment, reduce pollution in the chicken house, and reduce the risk of environmental pollution.
7. Improve breeding efficiency: Cage breeding is conducive to improving the survival rate, growth rate and meat quality of broilers, thereby improving breeding efficiency.
   In summary, the use of cages for breeding broilers has many advantages, which can improve breeding efficiency and achieve sustainable development. In our country, the research and popularization of cage has become an inevitable trend for aquaculture.
