New York AGRICULTURAL EXPERIMENT STATION. 71 
production of a large proportion of the fat in the milk. This con- 
clusion is not irrational in view of the fact that Lawes and Gilbert 
and other investigators have demonstrated the formation of fat in 
swine and other animals from starch and sugar. 
THE INFLUENCE OF THE RATION UPON THE COMPOSITION OF THE 
CARCASS. 
At one time the influence of the ration upon the composition of 
the animal’s body was much discussed and one: experiment!? was 
instituted at the Station for the purpose of comparing rations 
heavily nitrogenous with one of a much wider nutritive ratio. One 
ration consisted of hay, bran and cottonseed-meal, and the other of 
hay and corn meal. These were fed to lambs. At the end of the 
experiment one lamb of each lot was killed and a mechanical analysis 
was made of the carcass. It was found that the carcass of the corn- 
fed lamb contained a much larger proportion of fat than the carcass 
of the lamb that was fed cottonseed-meal. This result is in entire 
accord with the outcome of Station investigations at other experi- 
ment stations.
