Ration Experiments With Swine 
ii 
“Product from slime tanks and offal tanks goes to fertilizer. 
These materials in themselves are highly undesirable, but in addi¬ 
tion they are usually allowed to lie around and undergo fermenta¬ 
tion, which produces division products which may be highly 
dangerous from a feeding standpoint. 
‘‘On the contrary in the manufacture of feeding tankage we 
use only select material from U. S. /Inspected and Passed animals 
and handle it promptly all along the line so that there is no pos¬ 
sibility of its undergoing fermentation or decomposition.” 
During the two years feeding at the station no ill effects upon 
hogs was caused by fertilizer tankage, but in view of the facts given 
above, while feeders, particularly those operating upon a large scale, 
may save considerable money by the use of fertilizer tankage, they 
should make sure of the process of preparation of the product before 
using it.

California Feed Barley 
This barley is not quite so satisfactory a feed as a good, plump 
brewing barley, but yet gives good results with alfalfa hay, alfalfa 
meal, or tankage. Use about nine parts of barley to one of tankage, 
or four parts to one of alfalfa meal. When fed with alfalfa hay put the 
hay in the racks letting them eat what they will and feed all the barley 
slop they will clean up. 
Barley and Sugar Beets 
The rations named above are ordinarily more economical than 
this, but if one has sugar beets to feed, use I part to 4 of grain and good 
results will be obtained from pigs of 150 pounds weight or over. They 
should not be used for pigs of light weight, as they are too bulky a 
feed. 
Rye 
Rye alone is not palatable and should be fed with other feeds. 
Alfalfa Meal 
In using alfalfa meal in slop with grain, it should be as finely 
ground as possible, and about four parts of grain used to each part of 
alfalfa meal. This is a ration that should not be fed to pigs weighing 
less than 100 pounds, as it is too bulky. 
Grain and alfalfa meal make a very economical ration as compared 
with grain and shorts.
