Oat (Avena sativa L.) has been traditionally a major crop for feed and forage in Turkey. The objective of this research was to study hay yield and quality of oat genotypes harvested at the late milk stage. One hundred oat varieties of worldwide origin were compared in field experiments in Samsun (northern Turkey) over two growing seasons (2007-2008 and 2008-2009). Significant differences between the tested oat varieties were observed for e plant height, hay yield, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF) and macro minerals (Ca, K, P and Mg). Plant height varied from 76.2 to 141.2 cm, hay yield varied from 6.03 to 11.83 t ha-1, crude protein varied from 58.8 to 136.4 g kg-1 dry matter (DM), acid detergent fiber and neutral detergent fiber varied from 333.2 to 424.8 g kg-1 DM and from 522.5 to 652.4 g kg-1 DM, respectively. Genotypes such as Sisko, Akiyutaka, Longchamp, Sanova, Flämingslord, Matra and Revisor were identified as the high hay yielding genotypes although their quality s was lower than that of the other genotypes. Furthermore, while some macro minerals were insufficient, others were in excess regarding healthy feeding. Hence, some form of commercial mineral supplement would be required for oat-based ration or oat legumes mixtures should grow for feeding productive livestock
