Colorado Agricultural Experiment Station 
1909-1910 EXPERIMENTS 
Eleven lots of ten head each were fed. The pens averaged from 
173 to 178 pounds per pig at the beginning of the experiment, and 241 
to 271 at the close. The pigs used were uniform in breeding, age and 
condition. 
The preceding table gives the results. 
California Feed Barley with Wheat Shorts or Alfalfa Hay. 
The check ration used in this series was California feed barley 2 
parts and wheat shorts 1 part. The ration stands about midway of 
the various rations used, both in gain in live weight produced and in 
cost of gain. Most of the other rations were combinations of various 
feeds with California feed barley, made with a view to find the proper 
proportions with protein supplements to secure cheapest results. 
The best ration in the series was California feed barley 1 part and 
corn 1 part, with alfalfa hay according to appetite. The hay was fed 
whole in racks. This is a ration that is available to many Colorado 
hog feeders, and because of its economy should be widely used. Where 
the barley was used with alfalfa hay alone, no corn being used, gains 
were not quite so cheaply secured, yet this ration was third in economy 
among the entire eleven rations, and at present prices of fertilizer 
tankage, would rank second in economy in producing gain, displacing 
the pen which gave best results from the use of fertilizer tankage. 
California Feed Barley and Fertilizer Tankage 
The ration which was second in point of cheapness of production 
was -that fed Pen 6, California feed barley 9 parts, fertilizer tankage 1 
part ; and that fed Pen 8 was close to it in economy, the ration being 
5 parts California feed barley to 1 part fertilizer tankage. The diff¬ 
erence in cost of production between these two was 16 cents per hun¬ 
dred pounds gain in live weight. Why Pen 7, fed 7 parts barley to 1 
part of fertilizer tankage should not have done as we'd as the other 
two cannot be explained by the character of the ration as it is a mix¬ 
ture standing between the two in amount of tankage used. 
Sugar Beets with California Feed Barley. 
This ration was fed Pen 9, using 4 parts of barley to 1 of sugar 
beets. The cost of producing gain was $5.37 per hundred pounds gain, 
which is a reasonable cost compared with that of other rations. 
Winter Rye. 
Because of special requests from mountain districts where winter 
rye is a useful grain crop, one pen was given rye without any supple¬ 
mentary feed. The feed did not prove satisfactory chiefly because of 
lack of palatability. The hogs would not eat it well and consequently 
made very small gains.— 8*4 pounds per head per week as compared
