BS = Brown Swiss and OB = Original Braunvieh; Protein yield (in kg); Stature (in cm); we calculated the differences row minus column, so negative values indicate superior horizontal groups and positive values indicate superior vertical groups. ^n.s. = not significant, * = (p < .05), ** = (p < .01), *** = (p < .001). EU _b = European base group (born before 1960), DE _b = German base group (born after 1960), AT _b = Austrian base group (born after 1960), CH _b = Swiss base group (born after 1960), IT _b = Italian base group (born after 1960), US _b1 = American base group (born before 1955), US _b2 = American base group (born after 1955), OB _b1 = Original Braunvieh base group (born before 1960), OB _b2 = Original Braunvieh base group (born after 1960)
