41,058 cows and heifers tested in 1939, excluding 973 animals
in herds tested during only a part of the season, and therefore
not class1fied, 23,777 were included in Class I. and 1925 in
Class III. Tlns is equivalent to 59;}; per cent in Class I. and
4; per cent n1 Class III. Thus, 59:} per cent of all the cows
and hefiers tested gave a milk yield equivalent to not less
than 800 gallons containing 3'5 per cent milk fat in the case
of3 a cow and 640 gallons in the case of a heifer; while only
4,, per cent gave a milk yield equivalent to less than 531
gallons containing 35 per cent milk fat in the case of a cow

in autumn and winter, yet it will be observed from the pre-
mling table that the proportion of animals qualifying for
inclusion in Class I. in 1939 is only 5 per cent lower than
ihat of 1936—namely, 641 per cent, which, taking into con-
Sideration the higher standards now adopted, is the highest
reached since the commencement of official milk recording
thirty-six years ago.
It will be observed also that when classified on the lower
standards previously adopted, the proportion of Class I. cows
and heifers to the total animals tested increased from 39;-
per cent in 1914 to 75-12— per cent in 1934, while the proportion
of Class III., or obviously unprofitable, animals was reduced
in the same period from 9 per cent to 1% per cent. These
figures indicate great improvement in recorded herds, yet do
not represent the full extent of the progress made since the
introduction of milk recording in 1903. It is estimated that
milk record herds generally are at the present time giving
higher average yields than unrecorded herds to the extent of
considerably over 200 gallons per cow per annum.
Improvement from milk recording is not confined to herds
officially recorded in 1939. A very much larger number have
been tested and recorded for longer or shorter periods since
the Association’s scheme of milk recording was introduced.
And when we consider the spread or diffusion of the benefits
arising directly or indirectly from milk recording, we find
that these penetrate widely in various directions other than
that of individual members of milk. recording societies. For
example, there is the effect on the remaining dairy herds of
the country. The wide dissemination annually of milk record
stock bulls and milk record cows for breeding purposes among
untested herds alone must exercise an incalculable improving
influence on a very large number of these herds. Such
influence is increasing with the extension of the practice of
using only milk record bulls in dairy herds.
There is also the powerful educational influence and force
of example permeating and leavening the whole mass of
dairy farmers. If a census could be taken in this connection,
it would probably be found that a considerable proportion
of herd owners outside the membership of milk recording
societies are in one way or another testing and recording the
milk yields of their herds who would never have done so had
systematic or official milk recording not been in operation.
The same consideration applies to the more enlightened methods
0f selecting, breeding, and feeding on milk record lines
which have been adopted in many herds not oflicially recorded.
There is another direction in which advantage from milk
recording is penetrating widely beyond the ranks of milk
recording societies. Increased efficiency in the production
of milk lowers the cost to the urban populations, and some
