Is antibiotic reduction related to pig welfare?

Inappropriate use of antibiotics leads to antibiotic resistance. Although several countries banned the use of antibiotics for growth promotion and prophylactic purposes, the global use of antibiotics is still quite extensive. Therefore, it is important to identify the main on-farm stressors in intensive swine production systems, to evaluate their negative impacts on pig health and welfare, and to find strategies to assess how welfare and health improvement of pigs contribute to antibiotic reduction in swine industry.

Animal welfare and environmental issues have been major concerns in the past decades. According to the World Organization for Animal Health “an animal experiences good welfare if it is healthy, comfortable, well-nourished, safe, is not suffering from unpleasant states, such as pain, fear, and distress, and is able to express behaviours that are important for its physical and mental state”.
