An object of the present invention is to provide meat having lower amount of saturated fatty acid. It has been found that by feeding a livestock animal with feed containing Lactobacillus plantarum BB-PLT (lactic acid bacterium BB-PLT strain) (NITE BP-02097), the saturated fatty acid contained in the meat decreases and the monovalent unsaturated fatty acid contained in the meat increases, after heat cooking. Accordingly, the present invention relates to, for example, Lactobacillus plantarum BB-PLT (NITE BP-02097), livestock feed containing the lactic acid bacterium, a method for raising a livestock animal for meat comprising feeding the livestock animal with the lactic acid bacterium, and edible meat obtained from a livestock animal raised by the raising method.
