The effects of involuntary coprophagy on the production of skatole in growing pigs


, : The effects of involuntary coprophagy on the production of skatole in growing pigs. Animal Production 53(1): 105-110

Six boars weighing about 65 kg were penned individually in preliminary observations to investigate their response to increasing levels of feces in a concentrate diet fed as a gruel. During an introductory 5-day period pigs were restricted to 1.5 kg concentrates plus 100 g fresh feces daily. The daily concentrate allowance was then increased to 2.2 kg and feces increased by 50 g/day providing the ration was consumed completely. Two animals showed diarrhea at intakes of 1 kg feces per day while the remaining four animals showed no signs of ill health at the maximum allowance of 1.4 kg feces per day. In the main experiment littermate pairs of the same sex (16 boars plus 16 gilts in total) were allocated to control (concentrates only) or treated (concentrates plus fresh feces) groups. Animals were housed in metabolism crates from about 55 kg live weight and the diet allowances were increased gradually up to 2.5 kg concentrates with or without 500 g fresh feces per day. This was achieved on day 17 and continued to slaughter some 40 days later when pigs weighed around 85 kg live weight. Levels of skatole and indole were significantly higher in the caecal contents of treated pigs at slaughter but similar in feces compared with controls. There was no effect of dietary treatment on skatole or indole levels in subcutaneous fat. It seems unlikely that natural coprophagy would contribute significantly to skatole and indole levels in carcass tissues.
