Having been on the National Champion Dairy Team, High Man in reasons at Waterloo and a student of Dr. Fred Foreman, I've heard that terminology and used it frequently in dairy reasons. Not in hog circles.... I assume they are referring to levelness and width of rump...Depending on the degree of muscling the width thingy can work two ways of course...The exterior width of rump may have little or no correlation to the width or height of pelvis...that's where the profitablility really kicks in terms of ease and ability to farrow unassisted....Its kinda a two way street we all want level wide rumps but not if the added muscle comes with a smaller pelvis or vulva...give me the more feminine females every time...
