484 FEEDS AND FEEDING 



per ton than cotton seed at $12 per ton. In a later trial Burns found that 

 when the allowance of cptton seed was increased beyond 8 Ibs. per head 

 daily the animals scoured badly, probably due to the large amount of oil 

 in the seed. On substituting cottonseed meal for the cotton seed they 

 recovered and made much larger gains. In a trial at the Arizona 

 Station, 60 Stanley found that it required 170 Ibs. of cotton seed to equal 

 100 Ibs. of low-grade cottonseed meal containing only 33.6 per ct. of 

 crude protein. 



753. Linseed meal. Thruout the northern states linseed meal is widely 

 used as a protein-rich supplement for beef cattle. (254) While it is lower 

 in protein than cottonseed meal, trials at various stations show that it is 

 worth fully as much or more per ton than choice cottonseed meal for 

 fattening cattle. This is doubtless due to its well-known beneficial 

 regulating effect on the system. 



In two trials by Allison at the Missouri Station 61 in which equal 

 amounts of linseed meal and cottonseed meal were fed with shelled corn, 

 corn silage and alfalfa hay or with corn silage and alfalfa hay, without 

 corn, the gains were slightly larger, except in one case, on linseed meal. 

 Also more pork was produced by the pigs following these steers. The 

 steers fed linseed meal sold at a slightly higher price per cwt. and with 

 both supplements at the same price per ton, the net return over cost of 

 feed was $5.52 per steer more for those fed linseed meal. In 3 trials by 

 Tomhave and Bentley at the Pennsylvania Station 62 steers fed linseed 

 meal with corn silage and shredded corn stover for roughage, and with 

 or without corn grain in addition, made slightly larger gains on the 

 average than steers fed cottonseed meal with the same roughages. With 

 linseed and cottonseed meal at the same price per ton, the profit per steer 

 was slightly greater for those fed linseed meal. Linseed meal was like- 

 wise found slightly superior to cottonseed meal in trials by Smith at the 

 Nebraska Station. 63 In one trial by Cochel at the Kansas Station 64 with 

 calves fed for baby beef, linseed meal was slightly more profitable than 

 cottonseed meal at the same price per ton, and in another trial the results 

 were reversed. On the average, linseed meal was worth a little more 

 than cottonseed meal. 



754. Soybeans; soybean oil meal. The protein-rich seed of the soybean 

 is well suited to serve as a nitrogenous supplement for fattening cattle. 

 In trials by Skinner and King at the Indiana Station 65 ground soybeans 

 gave good returns when 2.5 to 3.0 Ibs. were fed per head daily to sup- 

 plement a ration of shelled corn, corn silage, and oat straw or clover 

 hay. Doubtless due to the high oil content of the soybeans, they had 

 rather too laxative an effect on the steers. Also, after the cattle had 

 been on feed for 90 to 100 days, they seemed to tire of the soybeans, 

 probably again due to the richness in oil. During the time when the
