Novel metabolites and enzymes involved in skatole metabolism are disclosed. The novel metabolites are 3-OH-3-methylindolenine (HMI); 3-methyloxindole (3MOI); indole-3-carbinol (I-3C); and 2-aminoacetophenone (2-AM). Measuring levels of these metabolites in a pig may be useful in identifying the pig's ability to metabolize skatole and its susceptibility to boar taint. The novel enzymes involved in skatole metabolism are aldehyde oxidase and CYP2A6. Enhancing the activity of these enzymes may be useful in enhancing skatole metabolism and reducing boar taint.
