of the self feeder,—in this case 50 pounds of hay for each hundred 
pounds gain. With hay at $5.00 per ton, the saving on one hundred 
pounds of gain is shown to be 11 cents, or about 3^4 cents per lamb. 
With four lambs per running foot this amounts to 14 cents saving 
in hay each season per running foot of rack. As stated in Bulletin 151, 
the cost of material for the rack is $1 per running foot. In the former 
experiment a saving of 56 cents per running foot was secured. The 
combined evidence of the two experiments gives an average saving of 
35 cents per running foot of rack each season when hay is at $5.00, a 
sufficient return to warrant the use of the racks. Of course as hay 
goes higher in price the saving is greater. The neatness of the 
feeding premises is an argument in itself for the self feeder, regardless 
of the saving in hay. 
Scotch Barley Compared With Corn 
Aside from the fact that barley is a large yielding crop in Colo¬ 
rado, it is a crop that ripens early in the season, and it can often be 
bought for a lower price than old corn, prior to the appearance of a 
good quality new-crop corn on the market. During this last season (Fall 
1912) new corn made a late appearance and was of poor quality because 
of early fall snows in the western section of the corn belt. As a result 
more barley was used for sheep feeding in the eastern Colorado feed¬ 
ing districts than ever before. Many feeders seem to have a prejudice 
against barley as a stock feed. Possibly this is because most experi¬ 
mental data with regard to the feeding of barley to hogs and to cat¬ 
tle shows a feeding value for barley of about one-tenth less than corn. 
My own observations with regard to barley for sheep indicated that 
barley was equally as good a feed as corn. This led to the experiments; 
and comparing Lots I and III in the last table above, we see that a 
trifle less hay and more grain was used by the barley lot than by the 
corn lot, resulting in a cost of $5.22 per hundred pounds gain for the 
barley^-fed lot and $5-19 for the corn-fed lot, when hay is $5.00 per ton 
and both barley and corn $1 per'cwt. This gives it an equal value with 
corn when fed with alfalfa hay.
