This invention relates to products and methods for improving sensory qualities of meat obtained from livestock. In particular, this invention relates to products and methods for reducing off-odors and off-tastes in meat from uncastrated male pigs (boar taint) or from other livestock fed on pasture. According to the invention, this is obtained by administering a product that contains an inducer of the constitutive androstane receptor (CAR). These include plant products derived from Artemisia spp, Citrus spp., Gingko biloba, Tagetes lucida, as well as vitamin E (alpha tocopherol). The CAR-inducer products of the invention may be used to reduce boar taint and thereby eliminate the need for castration of male pigs.
