326 FEEDS AND FEEDING 



mixture of 5 or 6 parts of shelled corn, 3 of oats, 2 of bran, and 1 of lin- 

 seed meal. On account of limited pasture an unusually large allowance 

 of grain was necessary during the summer. No effort was made to secure 

 extreme weight, the colts being kept merely in good growing condition. 

 The average gain per head was 727 Ibs., the fillies averaging 1.317 Ibs. 

 in weight as 2-year olds. 



During the first winter the average daily gain was 1.45 Ibs. and the 

 average ration was 5.8 Ibs. of the grain mixture with 11.8 Ibs. of hay or 

 7.4 Ibs. of hay and 8.2 Ibs. corn silage as roughage. During the sum- 

 mer they were fed on the average 6.7 Ibs. grain and 6.0 Ibs. hay per day 

 in addition to pasture, the average daily gain being 1.34 Ibs. The 

 second winter the average ration was 9.2 Ibs. grain and 17.1 Ibs. hay, 

 and they gained on the average 1.30 Ibs. daily. At 1912 prices the cost 

 of feed was $53.97 per head for the first year after weaning, and $92.96 

 for the entire 18 months. 



Various rations for raising draft colts have been tested in 3 trials by 

 Edmonds and Kammlade at the Illinois Station. 14 In these trials pure- 

 bred draft fillies have been fed from weaning time until they were about 

 2 years old. In one trial a mixture of 40 parts of corn, 40 of oats, and 

 20 of bran was compared with equal parts of corn and oats. Alfalfa hay 

 was fed the first winter, and alfalfa hay and a little oat straw the second. 

 In summer the fillies were allowed 1 acre of pasture a head and were 

 given concentrates in addition. Both lots gained on the average 1.4 Ibs. 

 a head daily. When 2 years old their average weight was 1,544 Ibs. and 

 their average height, 15 hands 31/4 inches. Lot I required on the 

 average 4,404 Ibs. concentrates, 5,762 Ibs. alfalfa hay, and 462 Ibs. oat 

 straw for 518 days, the feed per head costing $109.04 with corn at 56 

 cents a bushel and other feeds in proportion. Lot II required slightly 

 less feed, and the cost was only $103.59. 



In another trial a mixture of 75 parts oats and 25 parts bran was 

 compared with the same proportions of corn and bran. The amount 

 of concentrates was reduced to the minimum needed for good growth. 

 Both lots gained 1.3 Ibs. a head daily, but the fillies fed oats and bran 

 required on the average 6.4 Ibs. per head daily, which was 1.0 Ib. 

 more than those fed corn and bran needed for the same gains. For a 

 490-day period the latter lot consumed per head only 2,647 Ibs. corn and 

 bran, 3,226 Ibs. alfalfa hay, and 2,490 Ibs. oat hay, the total feed cost 

 per head being but $74.21. Tho less feed was required when corn was the 

 chief grain fed and the cost was less, it was the opinion that the quality 

 of the fillies was a trifle better when more oats were fed. The mixture of 

 oats and bran proved most satisfactory, disregarding the cost. 



524. Substitutes for oats. To determine whether good draft colts 

 could be grown without oats McCampbell fed 2 lots of high grade draft 

 colts at the Kansas Station 15 from weaning until they were two and 

 one-half years old. The first lot consumed during this time per head
