It is common practice for feed barley to be purchased on sample specific weight. It can be argued that this historic measurement may give a misleading indication of its energy and feeding value. If this were to be true, then 6-row barleys which have a number of agronomic advantages, including high yields, could be discriminated against when compared to the more common 2-row barleys. Manitou is such a 6-row barley, which has out-yielded the best performing 2-row varieties by 6% in England (NIAB Recommended List 1991), and by 28% in Scotland (Scotland Agricultural Colleges Recommended List 1991). Trials were undertaken to compare Manitou and Marinka (2-row barley) at similar thousand grain weights (TGW), but different specific weights (sp.wt), with growing and finishing pigs.
