Milk-Yield Tests. 
97 
In the cases of one Shorthorn, one Guernsey, and the two 
Red Polled cows, the non-churnability of the milks was patent ; 
but as the prizes were awarded on one churning only, I did 
not churn these buttermilks to see what was left in them. 
This non-churnability of milk seems to be rather prevalent 
with the Red Polled breed ; but as I have not had an opportunity 
of examining that milk under the microscope, I cannot say 
for certain that the milk from that breed contains a large 
proportion of small and irregular-sized fat globules, although I 
am of opinion that such is the case. 
In the milking trials samples of milk were taken for 
analysis by Dr. Yoelcker. I have taken the average percentage 
of fat for each breed, multiplied the weight of milk by the 
butter fat, and added 10 per cent, for moisture. 
The results are shown as follows : —

The non-churnability cases mentioned above may help to

II. MILK- YIELD TESTS. 
The milk-yield prizes which were offered by the Society 
at the Show at Park Royal in 1905 were in advance of all 
previous competitions of this description, in that separate 
prizes were given to ten breeds which rank as dairy cattle, 
thus avoiding competition between breeds, while as a condition 
precedent every animal entered for these prizes had first to be 
judged in the inspection class of its respective breed. 
Under these conditions purity of pedigree became a sine 
qua non , and the need of the combination of form with 
utility was accentuated. 
Special open prizes were also offered in Class 161 through 
the English Jersey Cattle Society, not only for those cattle
