  • Patent number: 5741508
    Abstract: Livestock and poultry are fed with feed containing at least one spice chosen from among the families Myristicaceae, Cruciferae, Rutaceae, Compositae, Pedaliaceae, Piperaceae, Leguminosae, Umbelliferae, Myrtaceae, Solanaceae, Labiatae, Lauraceae, Liliaceae and Zingiberaceae, whereby the active ingredients of the spice taken into the bodies of the thus-fed livestock and poultry are transferred to their internal fat thereby to modify their meat and to improve the smell of their fat. Accordingly, the fatty smell of the meat and fat to be obtained from the thus-fed livestock and poultry is removed and the freshness-keeping power of the meat and fat is enhanced. As the spices may be added to feed, livestock and poultry may efficiently take the spices with ease.
