| Skatole, one of the main causes of boar taint, derives from tryptophan in the large intestine and accumulates in the fat tissue of boars, thus decreasing meat quality. We hypothesize that energy of roughage promotes growth of skatole reducing microbes. Therefore, we compare the two roughages grass-clover-silage and straw, regarding the effect on concentrations of skatole and androstenone in the fat tissue. The experiments are currently ongoing and will help to evaluate special feeding strategies as an alternative to castration, thereby promoting animal welfare and product quality. |

| Fattening of entire male pigs is a useful alternative to piglet castration but the problem of boar taint is still unresolved. The object of the present study was to test the effect of (i) two different terminal sire lines (Danish Duroc, Du vs. Piétrain, Pi) and (ii) two different feeding strategies (without (-) vs. with (+) raw potato starch prior to slaughter) on the prevalence of boar taint in organic pork production. The results show that entire male growing-finishing pigs of Du origin have significantly higher androstenone concentrations in shoulder back fat than those of Pi origin whereas the feeding strategy has no significant effect. Concerning skatole, both genetic origin and feeding strategy significantly affect concentrations in shoulder back... |
