* At the rate of protein .07; carbohydrates .7 and ether extract .01 per cwt. 
From this it is seen that the daily average of nutrients 
available to a pound of milk did not differ materially from 
the Lehmann standard except that the herd returned a 
pound of milk for each .05 of available protein, being about 
60 per cent of the amount prescribed by the standard. The 
average per cent fat in the milk during the winter was 4.07, 
which is a trifle above the average quality in this country. 
The discrepancy in the amount of available carbohydrates 
consumed, per pound of milk yielded is greater than is indi- 
cated by the above comparison; because the standard pre- 
scribes 8 pounds per thousand pounds live weight for food 
of maintenance while only 7 pounds are allowed in this 
table. If this factor is applied to the Lehmann standard it 
makes an allowance of .27 of a pound of carbohydrates to 
a pound of milk. 
The herd came out of the winter in excellent condition 
and gave every evidence of having been amply nour- 
ished, and returned a maximum yield of both milk and 
butter fat. The following winter, 1895-6 the herd was 
composed of, practically the same animals, received on an 
average a daily allowance of 2.59 pounds of digestible pro- 
tein, and its performance compared with the winter’s work 
in review, was as follows:
