631. Velvet bean. Scott of the Florida Station, 1 during a feed- 

 ing trial extending from January to April in which either velvet 

 beans in the pod or cotton-seed meal was fed to cows along with a 

 basal ration of wheat bran and sorghum silage, secured the follow- 

 ing returns: 



268 Ibs. velvet beans in the pod, with bran and silage, produced 935 Ibs. milk 

 95 Ibs. cotton-seed meal, with bran and silage, produced 937 Ibs. milk 



It will be seen that, fed with bran and silage, 268 Ibs. of velvet 

 beans in the pod produced substantially as much milk as 95 Ibs. of 

 cotton-seed meal. Scott reports that the Florida farmer can produce 

 5 tons of velvet beans for the cost of 1 ton of cotton-seed meal. (263)

632. Wheat bran. The Copenhagen Station 2 conducted feeding 

 trials with 447 cows on several Danish farms as follows: To one lot 

 was fed a mixture of equal parts of ground barley and oats ; to a sec- 

 ond a mixture of half wheat bran and half mixed grains; and to a 

 third wheat bran alone. The results are summarized below : 



Wheat bran compared with a mixture of ground oats and barley. 



The results show that wheat bran fed alone is fully as valuable as 

 a mixture of equal parts of ground barley and oats. Bran, however, 

 should rarely be so fed, but always in combination with some feed rich 

 in starch, such as corn, rye, barley, etc., and with some legume rough- 

 age to furnish lime, which it lacks. (165) 



633. Wheat shorts v. wheat bran. The Copenhagen Station 8 con- 

 ducted trials with 240 cows on several farms in which wheat shorts 

 (presumably of good quality) was fed in comparison with wheat bran. 

 The shorts gave slightly larger returns, tho the difference was small. 

 Combining the results of this trial with those in the preceding ar- 

 ticle, we may conclude that wheat bran, wheat middlings, and good
