Abstract: This study aims to review and identify stressors that affect the productivity of animals; knowledge on effects or implications of stress on animal productivity, understanding the response of the animal to the stressors and strategies for alleviating stress in farm animals. Farm animals are regularly faced with different stressors. Most stressful conditions including cold, heat, handling, transporting, temperament, introduction to a new herd or flock, diseases and parasites. Stress is a reflex reaction revealed by the inability of an animal to cope with its environment which may lead to many unfavorable consequences, ranging from discomfort to death. It covers the behavioral and biological responses to a wide range of abiotic stressors such as social interactions or rough handling, common farm practices (castration, dehorning, teeth clipping, shoeing, weaning crowding, etc.) improper feeding, exposure to adverse climatic conditions, exercise, work and transport, etc. Stress reduces the fitness and productivity of the animal. Little is known about the signs of stressed animals in turn, almost all farmers lose their animals through death. Moreover, in the future population growth, urbanization and income growth in developing countries are fuelling a massive global increase in demand for food of animal origin. However, the effect of stress has a great impact on the productivity of farm animals. The issue must receive more research attention in minimizing farm animal stress and optimizing product yield and quality.
