Production and meat fatty acids profile of Hereford steers fed on pasture with and without oat grain supplement. Chile, VIII Region

Live weight gain (LWG) and meat fatty acid composition (FA) were evaluated in Hereford steers fed on pasture with or without oat grain. The study site was non-traditional pastures were used in the dryland Andes foothills, VIII Region, Chile (36° 49' S, 71° 55' W), including forages such as...
