1 This experiment indicates that 1 pound of fish meal is equal to about 1.24 pounds of cottonseed meal. 
It will be noted that the fish-meal groups produced slightly more 
milk but a trifle less butterfat, while the grain and alfalfa hay were 
practically the same for each group. The fish-meal groups consumed 
almost 400 pounds more silage, but to offset this they gained 24 
pounds more in body weight than the other groups. Perhaps it may 
be assumed that one will about balance the other, and if so we have 
a direct comparison between the fish meal and cottonseed meal. 
Apparently, for dairy cows, the fish meal is worth pound for pound 
20 or 25 per cent more than cottonseed meal. 
Fish meal is not so palatable as cottonseed meal, though no diffi- 
culty was experienced in getting the cows to eat all that was offered 
them. No bad effects on the physical condition of the cows were 
observed. The flavor of the milk apparently was not impaired in 
any way either by exposing milk to the odor of fish meal or by feed- 
ing the cows 4 pounds of the fish meal one hour before milking. 
While it can not be positively stated that fish meal has no bad effect 
whatever on the flavor and odor of milk, such effect, if any, is so 
slight as to be unnoticed by the ordinary consumer. 
PEANUT FEED COMPARED WITH COTTONSEED MEAL 
The residue from cold-pressed unhulled peanuts furnished by the 
Bureau of Chemistry was fed in comparison with cottonseed meal to 
six cows for two periods of 70 days each. The other concentrates 
used in the ration were equal parts corn meal and wheat bran.
