Influence of environmental factors on the onset of digestive disorders of the weaned piglet

Abstract

An ecopathological study was conducted in Brittany (France) in 89 conventional herds in order to identify the main circumstances that permit the onset of weaning disorders. By comparing the different practices in affected and non-affected herds using multidimensional data analysis methods, a combination of 10 variables was found. These variables are considered as predisposing factors and called "risk factors". They are connected and have a cumulative effect. Preparation to weaning (piglets' weights at weaning, feeding level ingested during suckling period) and environmental conditions of reception of the weaned piglet such as housing requirements are needed.
