570 EXPERIMENT STATION RECORD. 



The cost of food is based upou the following prices of grain per 100 

 lbs. ground: ^Vbeat, 75 cts. ; peas, $1.25; corn, 75 cts. ; barley, 80 cts. ; 

 and bran 50 cts. The lot on peas made the largest gain and the best 

 gain for the food consumed, but at the ruling prices the lot on wheat 

 made the cheapest gain. Deducting the cost of the bran and allowing 

 4 cts. per pouud live weight for pork, the following prices per bushel 

 were realized: Wheat, 89.4 cts. ; peas, $1.02; corn, 70.4 cts., and barley 

 59 cts. "One hundred pounds of wheat in the mixture proved to be 

 equal to 88 lbs, of peas, to 118 lbs. of corn, and to 121 lbs, of barley." 



Feeding silage vs. dry fodder, J. W. Sanborn ( Uiah Sta. Bpt. 1S93, 

 pp. 11-20). — Three lots of 3 yearling steers each were fed from Decem- 

 ber 21 to March 29 as follows: Lot 1, silage weighted or unweighted; 

 lot 2, coru fodder from the same field, which had been ensiled after 

 drying, and lot 3, dry corn fodder stored in a loft. In addition to these 

 materials grain (not described) and moist hay or straw were fed. The 

 quantity of silage given amounted to about 30 lbs. This is all the ani- 

 mals could be induced to eat, and the food of the other lots was made 

 to conform in dry matter approximately to that fed the silage lot. This, 

 according to the author, explains the fact that during the 3 months the 

 silage lot lost 58 lbs., the lot on ensiled dried fodder 47 lbs., and the lot 

 on dry corn fodder gained 71 lbs. It is believed that a good growth 

 would have been made had the silage lot been given all the dry food 

 they would eat. 



At the conclusion of the experiment the steers were slaughtered, 

 and the weight of the parts and results of analyses of the parts of the 

 carcass are tabulated. The carcass of the silage lot averaged 74.8 

 per cent of water and 7.65 per cent of fat, as compared with 74.9 per 

 cent of water and 9.31 per cent of fat in case of the lot fed corn fod- 

 der. Counting the water in the food, the silage lot consumed consider- 

 ably more water, although they drank only about half as mu(;h as the 

 others. Previous experiments at this station on the above subject 

 have been reported in Bulletin 19 of the station (E. S. R., 4, p. 738). 



"This test will prove the last that the writer will undertake at the Experimeut 

 Station of Utah on this subject. He has become completely convinced that the 

 process of preservation of food by the silo, in the perfect harvest climate of Utah, 

 is a costly, wasteful, and, in almost every conceivable respect, an undesirable 

 method of food preservation. Coru fodder, or any other kind of fodder, in our 

 climate can be cured to almost ideal perfection." 



Feeding roots, J. W. Sanborn ( Utah Sta. Bpt. 1893, pp. 31-23).— To 

 compare roots with no roots on steers 3 steers were fed mixed hay, corn 

 fodder, grain, and carrots, and 2 other steers received the same materials 

 without roots from March 29 to May 10. The gain per steer was G0.3 

 lbs. for the lot with roots and 71 lbs. for the lot without roots, and the 

 dry matter eaten per steer daily 15,4 lbs. by the lot on roots and 14.1 

 lbs. by the lot without roots, 



"In all previous trials, covering several years, with various kinds of roots, we 

 have failed to find that a pound of dry matter in roots is more valuable than the 

 ordinary air-dried fodders,"
