pure aud as result are practically
sure to perpetuate their chsrNcteris-

The purity OF our various breeds
now is carefully protected by breed
organizations and NJ farm animal can
be registered whose sire and dam are
not registered. 30 in the case OF
many types of livestock their Anees=
try can be traced b. their progenltors
In the British fsfes or Europe.
In the case Of dairy cattle as well
as with other types there are excel
lent examples. furnished by highly
productive farmers herds. which
show that purebred sires are valuable
in the building of efficient herds.
According to thu 1920 census the
average milk Yield per COW In thss
country is 1927 pounds. and yet there
are many herds OF dairy cattle. de-
veloped by the use of purebred dairy
sires. which average more than twice
this amount per COW
In order to definitely demonstrate
the value OF the purebred dairy sire
In developing profitable dairy herds
the Iowa State College planned very
valuable and interesting experiment
in 1907 A man was sent into the
Ozark Hills of Arkansas to select
herd OF inferior cattle which showed
the characteristics Of no recognized
breed. These cattle were exceeding
ly Inferior They were rough and
irregular with no one typo predomi-
mating. They lacked capacity OF
body and udder and thus made poor

These COWS were kept with the col
iege herd and given similar treat
ment. Careful Iecords were kept "
their production mF1 that of their on

bred to a Guernsey bull. another 10 a
Jersey and another to Hoistein.
Their progeny in turn were bred toi
other bulls OF same breed and 10 on
until now cows carrying three
crosses OF pure bioof are being mlk-
ed In the college herd.
