486 FEEDS AND FEEDING 



not so economical a source of protein as cottonseed meal at $32.66 a ton, 

 or alfalfa hay at $15.00 a ton. In 4 trials at the Nebraska Station 69 Smith 

 found that when fed as a supplement to corn and prairie hay, corn stover, 

 or corn silage, bran produced somewhat smaller gains than linseed meal, 

 cottonseed meal, or cold-pressed cottonseed cake and the gains were more 

 expensive. 



757. Gluten feed. Tho most commonly fed to dairy cows, gluten feed 

 is a satisfactory nitrogenous concentrate for fattening cattle. (210) In 

 trials at the Missouri Station 70 in which the value of various supplements 

 to corn for steers f various ages on good bluegrass pasture was compared, 

 Mumford found that steers fed linseed or cottonseed meal and corn 

 generally made slightly larger gains than others fed gluten feed and 

 corn. In trials by Evvard, Dunn, and Savin at the Iowa Station 71 in 

 which gluten feed was fed to 2-year-old steers as a supplement, combined 

 with a small amount of linseed meal, satisfactory gains were made but 

 there was less profit than when linseed meal was used as the only sup- 

 plement. 



758. Dried distillers' grains; distillery slop. Tho dried distillers' 

 grains have been fed most commonly to dairy cows they may be used 

 satisfactorily as a protein-rich supplement for fattening cattle, if they 

 are cheaper sources of protein than linseed or cottonseed meal. (283) 



Before the advent of national prohibition many cattle were fattened 

 on the wet distillery slop or mash in the vicinity of distilleries. In such 

 feeding the slop is pumped from the distillery to the feed lots, where it 

 is fed in troughs. In addition to the slop an average of about 3 Ibs. of 

 cottonseed meal is fed per head daily, with 10 to 15 Ibs. of hay, straw, 

 bluegrass chaff, or cottonseed hulls. The roughage and the cottonseed 

 meal are usually mixed with the slop, tho sometimes the steers are per- 

 mitted to drink the clear slop. 



759. Dried brewers' grains According to Pott, 72 in Germany dried 

 brewers' grains are well esteemed as a concentrate for fattening mature 

 cattle, meat of good quality being produced on dried brewers ' grains, fed 

 as the only concentrate with potatoes, beets, and dry roughage. (228) 



760. Peanut meal and feed; velvet beans. Peanut meal from hulled 

 nuts is an excellent supplement for cattle, being even higher in protein 

 than is cottonseed meal. In a trial by Burns at the Texas Station 73 

 peanut meal containing 51.7 per ct. crude protein was compared with 

 choice cottonseed meal containing 44.8 per ct. crude protein, as a sup- 

 plement to a ration of ground milo, corn or sorghum silage, Bermuda 

 hay, and cottonseed hulls. Due to its higher protein content, less peanut 

 meal was needed to balance the ration than of cottonseed meal. The 

 steers fed peanut meal made slightly more rapid gains than those fed 

 cottonseed meal and returned slightly more profit with both supplements
