As some of the cattle included in the above were not 
entered for the milk-yield tests, a sample of their milk was not 
taken for analysis. It is therefore impossible to compare the 
average yields of butter with the calculated yields as was done 
in last year’s report. 
II. MILK-YIELD TESTS. 
As in the butter-test classes, the milk-yield prizes given 
by the Society at Derby were on the same liberal scale as in 
1905, the conditions for entry and the points to be gained — 
with one slight alteration — being similar to those of the 
preceding year. The one alteration was that the Jerseys and 
Guernseys, in order to qualify for a prize or commendation, 
had to obtain the same number of points as the cows of the 
larger milking breeds. 
The following scale of points regulated the prizes : 1 point 
for every pound of milk ; 1 point for every completed ten days 
since calving, deducting the first forty days. Maximum points 
for lactation, 12. Four points for every 1 per cent, of fat 
shown on the average of the two milkings. Fractions of pounds 
of milk, percentages of fat, and incomplete periods of less than 
ten days were worked out in decimals and added to the total 
points. No prize or commendation was given unless the 
following points were obtained : —

In cases of equality of points, it was provided that the prize 
should be awarded to the cow which had been the longest time 
in milk. Highly commended cards were given to all animals, 
other than the winners of the prizes, which obtained the 
above-mentioned points.
