Western ewes of the three predominant types (Texas ewes or fine
wools, Blackface crossbreds, and Northwestern Whiteface crossbreds)
commonly found in Kansas were secured 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 the same ewes are not 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.
