Western ewes of the three predominant types (Texas ewes or fine
wools, Blackface crossbeds, and Northwestern Whiteface crossbreds)
commonly found in Kansas were obtained as ewe lambs in the fall of
1951 and bred to Hampshire, Suffolk, Shropshire, and Southdown rams
two seasons. A different set of yearling rams has been used each year,
and the ewes are being rotated so that no ewes are bred to the same
breed of ram each year. Lamb production and wool production records
are being obtained from the different types of ewes, and lamb production
figures are being obtained for the four sire groups.
