Report of the Dairy Husbandman. 
—-_ +e 

To the Director of the Storrs Agricultural Experiment Station: 
SIR:—I herewith submit a brief outline of the work in the 
dairy department during the past year. 
FEED TRIALS WITH PIGS. 
During the past year twelve lots of pigs have been fed skim 
milk and middlings. When fed in the proportion of one of 
‘middlings to four of milk, the cost of 100 pounds of gain was 
$4.45. When fed in the proportion of one of grain to eight of 
milk, the cost of roo pounds of gain was $4.95. 
CREAMERY PROBLEMS. 
Samples of skim milk from hand separators and Cooley 
creamers have been collected and tested with the Babcock test. 
Pure cultures have been used in ripening cream, and the 
quality of butter has been compared with that made from 
cream ripened with skim milk starters. A large number of 
samples of cream have been tested, and a comparison has been 
made of the results of weighing and measuring samples. 
FEEDING TRIALS WITH COWS. 
An experiment was undertaken to show the value of nutri- 
ents in concentrates compared with the nutrients in roughages. 
Two dry cows of the same age and condition were fed a main- 
tenance ration for a period of 100 days. Fifteen pounds of 
hay containing 7.4 pounds of dry matter were found to be 
equivalent to 6 pounds of corn meal containing 4.3 pounds 
of dry matter. The difference in the value of nutrients in 
grain and hay is attributed to a difference in the energy 
required for digestion. A similar trial with milch cows is 
also reported.
