FEEDING EXPERIMENTS. 1 
DAIRY COWS. 
The results obtained by the Dairy Division of the Bureau of Animal 
Industry by feeding the fish meal described above to dairy cows, 
were sufficiently satisfactory to warrant a more extended study of its 
value as a dairy feed. This work is to be undertaken during the 
coming winter. The preliminary experiments showed that the cows 
fed on a ration containing fish meal gave a greater yield of milk than 
cows fed on a similar basal ration containing no fish meal, but con- 
taining cottonseed meal. The milk from the cows which were fed 
fish meal contained a lower percentage of butter fat, but the total 
yield of fat obtained was approximately the same for the two groups. 
There was some variation in the readiness with which the animals ate 
the ration containing the fish meal. As a rule cows which have not 
been highly fed on feeds for which they have a fondness, will eat a 
fish-meal ration readily and are eager for it. In these tests the feed- 
ing of fish meal had no detrimental effect on either the milk or 
butter. 
POULTRY. 
The feeding experiments with poultry and with growing and fat- 
tening pigs were conducted by the Animal Husbandry Division of 
the Bureau of Animal Industry. 
In the test with poultry a pen of laying hens fed a ration contain- 
ing the fish meal was compared with a pen of the same breed fed 
a ration which was the same, except that in it meat meal was sub-

Rawl, Chief of the Dairy Division, of the Bureau of Animal Industry, acknowledgment 
is made for their cooperation and interest in the feeding experiments with the fish meal 
prepared from the waste in the packing of sardines.
