When two young bull aristocrats |
started out on journey to their new |
home in Idaho recently. an experiment |
which will interest cattle breeders was
started under way. These two bulls. |
both Of which have enviable family
trees, were sent to the University Of
IdahO-nOt to learn-but to teach, and
the subject they will demonstrate is
1.-THE Best Method of Fixing and In
surfing Uniform Transmission of High
Production in Dairy Cattle"
Better Animals In Larger Numbers.
The shipping Of these two bulls, one
HOlstein and one a Jersey. was the
first step in carrying out cO-Opera-
tive experiment, undertaken by the
dairy division of the bureau Of animal
industry, United States department of
agriculture, and the department of
dairying. University of Idaho. The
object is not to improve the high pro-
ducing dairy animals already in ex-
istence, but to determine a method of
breeding that will produce the better
animals in large numbers. When this
method is determined and put to prac-
teal use, as 1t undoubtedly will be, it
will result in great advance to the
dairy industry. 1t is the average pro-
duction-the production Of the rank
and file-that counts, and this expert
nent Is aimed at raising that average.
rather than producing few record
breaking cows.
The experiment to be carried out at
the University of Idaho is part of a
general plan for extensive breeding ex-
periments, outlined by n. n. Graves
of the federal departments dairy divi-
sion. Other experiments similar to
the Idaho project will be carried out
directly with the herds of the dairy
division and comparatively with herds
of state experiment stations and indi-
vidual breeders. These experiments
will fill long felt need for a series of
carefully planned tests, involving a
large enough number of animals. and
extending over a sufficient length of
time to warrant accurate and definite
conclusions as to the best method of
breeding. While the need for this
work has long been recognized. the
cost of the work and organization re.
quired to handle 1t successfully has
prevented private individuals from try.

A Unique Experiment
In the Idaho experiment the follow

pared: In-breeding VS.. out-breedine
and line-breeding VS.. out-breeding. As

type of work is included in the general
plan, it will be carried on with thu
