Suitable density for feeding pigs
Pig feeding density refers to the area occupied by each pig pen, usually expressed as "per pig". Feeding density indicates the density of pigs in the house.
Feeding density had a great influence on the air environment condition in the house. If the number of pigs in the house is large, the heat emitted will be more, which is beneficial to the heat preservation of the pigsty in winter, but not conducive to the heatstroke prevention and cooling in summer; it will increase the harmful gas, water vapor, dust and microorganism content in the house, and at the same time, it will cause frequent fighting among pigs, affecting food intake and rest. If the number of pigs raised in the house is small, the total construction area of the pigsty will increase, and the civil construction investment will be increased. At the same time, it will not be conducive to the heat preservation of the pigsty in winter. Therefore, all types of pig herds should have an appropriate feeding density.
