MILK. 
Commencing January 2, and extending over a period of forty-seven 
days, daily examinations of the milk from four Jersey cows were made, 
for the purpose of ascertaining the influence of different rations on the’ 
quantity and quality of the milk. Detérminations were made in the 
milk obtained at each milking of the specific gravity, per cent of cream 
and solids, and in the mixed morning and evening milk each day of 
fat, nitrogen, sugar and ash. ‘The results obtained, together with the 
analyses of the rations fed, are given in another portion of this report, 
and will not be repeated here. 
In the report of the station for 1882 is given an analysis of milk 
from fatigued cows. Hoping to find some explanation of the phenom- 
enal richness of this milk the following experiment was tried: The 
morning’s milk from one of the same cows was carefully analyzed, and 
throughout the day the cow’s udder was subjected to continuous hand- 
ling, with the intent of producing, as far as possible, the same me- 
chanical effect upon the milk glands,as had been produced by the 
jarring of the car. The evening’s milk was then analyzed in the same 
manner as the morning’s had been. 
Both analyses are given: 
Morning milk. Evening milk .

It will be seen that the effect of the experiment was to considerably __ 
diminish the solids. The real loss is no doubt more than is indicated 
above, as during all of our experiments, the solids in the evening’s: 
milk have been above one-half per cent higher than ‘in the morning’s 
milk. ‘The loss falls principally upon the fat, although each of the 
constituents is slightly diminished. ) , 
In the milk from fatigued cows the solids were largely increased, the 
increase being wholly due to increased amount of fat, the other solids 
being less than above. More influence must be attributed to insuffi- 
cient food and deprivation of water than to any mechanical effect of 
the journey. An analysis of the first milking after the cows arrived 
at the station is inserted here, and to facilitate comparison an analysis 
of milk from the same cows after they had become rested and accus-. | 
tomed to the place.
