Abstract

More accurate and sensitive visualisation of faecal contamination in the abattoir would significantly reduce the risk posed by harbouring pathogenic micro-organisms. We carried out a preliminary investigation of the range of fluorophores found naturally in faeces from typical ruminant diets. Sixteen ewes were offered either: i) fresh forage (FF), ii) grass silage (GS), iii) grass hay (GH) or iv) concentrate and barley straw (CB). Animals offered FF diets had a greater concentration (P
