The correct option is B A and C
Poultry farming is the rearing, breeding and caring of various types of domestic birds for the commercial production of eggs and meat.
One of the most important aspects of good poultry farming is to house the birds properly and provide them proper care, shelter and a hygienic disease-free environment.
Good housing conditions in poultry farms include:
Provision for good ventilation: Maximum yield of poultry can be obtained by keeping the birds in a clean, dry and comfortable place that has good ventilation. Raising the birds in closed and poorly ventilated houses interferes with their breathing. This affects their health and productivity.
Maintaining an appropriate temperature within the poultry farms: High temperatures can have detrimental effects on the poultry and can create a stressful environment. This will affect egg production and egg quality of layers. It will also reduce the growth rate in broilers. Thus, it is necessary that poultry farms are kept reasonably cool in the summers and warm in the winters.
Appropriate lighting: Duration of exposure to light and intensity of light is crucial in increasing egg production. Birds reared under proper lighting lay more eggs.
Waterlogging is accumulation of water in an area. This may lead to growth of pathogens and create unhealthy living conditions which will adversely affect the health of the birds. A good drainage system is required to prevent waterlogging in the poultry farms and to have a clean and dry environment.
