16 STORRS AGRICULTURAL EXPERIMENT STATION. 
Report of Dairy Husbandman. 

To the Director of Storrs Agricultural Experiment Station: 
S1r:—I herewith submit a brief outline of the work of the 
Dairy Department for the year ending June 30, 1903. 
Observation and experience with a tuberculous herd of dairy 
cows extended over a period of several years. The data col- 
lected were published in Bulletin No. 24. 
In this report may be found records showing the food cost of 
raising eighteen dairy calves. Nine were raised on skim milk 
and hay, and nine on a similar ration, but with the addition of 
a small amount of grain. 
Observations were made of the milk flow and butter fat pro- 
duction of cows following dehorning. ‘Tables are given show- 
ing the shrinkage as the result of this operation. 
The amount of milk secured by different milkers in equal 
periods from the same cows was ascertained. <A score card for 
judging efficiency in milking has been formulated. 
During the past winter two groups of eight cows each were 
fed, in alternate periods, rations containing the same kind and 
amount of roughage and the same amount of grain, but of dif- 
ferent quality. The two rations contained about 1.5 and 2 
pounds of protein respectively. It seems best to repeat this 
feeding trial before conimenting on results. | 
The effect upon the milk flow, following the application of 
‘‘fly repellants’’ to-dairy cows, was investigated last summer. 
The work will be continued during this season. | 
At the present time an experiment to ascertain the compara- 
tive food value of milks of different quality is in progress. 
Various substitutes for milk and skim milk in raising dairy 
calves have been tried the-past winter. The trials thus far 
have been unsatisfactory, but this work will be continued. 
Respectfully submitted, 
CHARLES L. BEACH.
