Screening of Piglets for Signs of Inflammation and Necrosis as Early Life Indicators of Animal Health and Welfare Hazards

Abstract

Ensuring animal health and well-being requires animal-based measures for early and direct intervention at the point of care. Insight into the pathophysiology of Swine Inflammation and Necrosis Syndrome (SINS) has led to a non-invasive, clinical scoring system that can be used in daily practice. This provides information on the cause of observed lesions for direct intervention in affected herds. The aim of the current study was to re-evaluate the practicality of the SINS scoring system under field conditions. In addition, this is the first study to provide insight into the prevalence of SINS on Dutch farms. This study involved the scoring of 5958 piglets from 20 visits on 13 farms randomly selected by a veterinary practice in the Netherlands. The results showed that up to 64.1% of the piglets had visible inflammatory alterations in different body parts within the first seven days of life. Sow rectal temperature, signs of coprostasis and water intake during pregnancy were significantly (p ≤ 0.05) correlated with the prevalence of SINS in piglets. In conclusion, the SINS scoring system is an easy-to-use, non-invasive diagnostic tool that summarises animal-based observations at the point of care, providing a valuable communication tool between farmers, nutritionists and veterinarians in their efforts to improve animal health and welfare.
