Stocking density pertains to the number of animals in a given space, typically measured in terms of animals per unit area. In animal agriculture, stocking density is an important factor in determining the welfare and productivity of the animals. High stocking densities can lead to increased competition for resources, such as food and water, as well as increased stress and aggression among the animals. On the other hand, low stocking densities can result in underutilization of space and higher costs per animal. Research in this area often focuses on finding the optimal stocking density that maximizes animal welfare, productivity, and economic efficiency. Studies may also investigate the effects of stocking density on animal behavior, health, and environmental impacts.
