The greater gains made by Lots I and II getting sugar beets 

 &'s a part of their ration point to the undoubted advantage of suc- 

 culent feed in a ration. 



The fact that Lot II made but a meager gain on a feed of 

 sorghum only was to have been expected on account of the one- 

 sidedness of the ration; for the same reason it would seem that 

 Lot I should have made better gains than Lot II, but such was 

 siot the case. This contradiction of results seems to point to the 

 important fact that the physical condition of feed must be reck- 

 oned with as well as its chemical composition in estimating its 

 feeding value. 



The relative gains made by Lots III, IV, and V are about 

 what the orthodox feeder would expect, Lot III on alfalfa hay 

 doing much better than Lot IV on sorghum, and Lot Von a com- 

 bination of the two, doing better than either. 



One conclusion the writer has reached, which may or may 

 tiiot be drawn from the figures above, is that one should 

 not attempt to feed sheep in Salt River valley without shelter. 

 There was but one severe storm during this trial but during the 

 week of that storm the sheep made practically no gain and one 

 wether in Lot I died. The sun, however, was worse than the 

 rain. March was an unusually hot March, there being many 

 days that the mercury went above 90 in the shade during the 

 heat of the day. On such days the sheep suffered perceptibly and 

 it seemed that the gain of several days melted awav under the hot 

 rays of a single day's sun. 



At the end of the trial the sheep were not in condition for 

 market. They were then turned on a three acre field of ripe and 

 partially dry burr clover and fed alfalfa and barley hay in addi- 

 tion. Later, they had a run on alfalfa and were fed wheat hay 

 on the side. There were no losses from bloat* 



On June 5th the bunch was sold to a local butcher at four 

 cents per pound, that being a little better than the prevailing 

 market price. When sold, 39 iheep weighed 3400 lb. This made 

 an average gain of .32 pounds per day from the time of their pur- 

 chase to their sale.
