There is a relationship between the welfare of animals and the safety of food obtained from them, since an animal that lacks welfare and therefore suffers stress is more sensitive to diseases and alterations, which may be present to a greater or lesser degree, in products derived from it.
Stress is nothing more than an animal response to situations that cause anxiety or fear, which not only involves changes in behavior in animals but also physiological and metabolic disturbances, which can lead to pathological problems and suboptimal zootechnical yields.
Lack of welfare on farms can be caused by different reasons, such as inadequate animal density or poor ventilation and temperature conditions. If these situations continue over time, the stress suffered by animals can lead to digestive, growth, reproductive disorders, increased sensitivity to infectious agents, etc. In short, there is a decrease in reproductive rates and product quality.
