Pig vision and management/handling

Pigs have a panoramic vision of 310º and binocular vision of 35-50º (Fig. 1). This means that compared to humans, pigs prioritise their lateral monocular vision and this increases their panoramic vision (greater capacity for detecting possible danger, food, other pigs, etc) and decreases their bifocal vision (greater difficulty for calculating distances).

Controlling the environment of the pig

This article explains the most important principles of environmental control in the pig barns, such as ventilation control, maintenance of temperature within the thermoneutral zone of the animals and of the relative humidity levels inside the barns.
