FEEDS FOE HORSES 309 



fully equal to oats. Not being particularly palatable, dried brewers' 

 grains should be mixed with other concentrates. Hooper and Anderson 27 

 of the Kentucky Station report the grains somewhat constipating for 

 horses and mules. (228) 



490. Leguminous seeds, Field peas, soybeans, cowpeas, velvet beans, 

 and horse beans may all be used in limited amounts as protein-rich sup- 

 plements for horses. (256, 261-4) All these leguminous seeds should be 

 ground and should not form over one-third the concentrate mixture, 

 else they may cause digestive trouble, owing to their heavy character. 

 In Europe horse beans and other varieties of beans are widely used in 

 feeding. 



491. Miscellaneous protein-rich concentrates. Gluten feed is most 

 commonly used for dairy cattle, but may be fed to horses in limited 

 amounts, mixed with better-liked feeds, as a protein-rich supplement 

 to balance the ration. (210) 



Gluten meal was used successfully as a supplement to corn meal in a 

 trial at the Iowa Station 28 but proved rather unpalatable to horses. 

 (211) 



Dried distillers' grains, fed by Lindsey 29 at the Massachusetts Station 

 as one-fourth of the concentrate allowance to horses, gave excellent re- 

 sults. Fed by Plumb 30 at the Indiana Station as one-third of the grain 

 allowance, they proved fairly satisfactory with some horses, but un- 

 palatable to others. (283) 



Cocoanut meal is a safe, tho rather unpalatable, feed for horses. 31 It 

 may replace oats to the extent of one-fourth the concentrates when 

 economy justifies the measure. (260) 



Peanut meal may be fed very satisfactorily to horses as a protein-rich 

 supplement. As high-grade peanut meal is as rich in protein as is 

 cottonseed meal, only 1 to 2 Ibs. per head daily will be needed to balance 

 a ration low in protein. (258) 



Oil cakes and meals from sunflower seed, rape seed, sesame, etc. are 

 fed to horses in different parts of Europe in quantities of 2.2 to 4.4 

 Ibs. per horse daily with good results. (259) 



Tankage and blood meal were found by Burkett at the North Carolina 

 Station 32 to be useful for run-down, thin horses, 1 to 2 Ibs. of tankage or 

 1 Ib. of blood meal being employed. Pott 33 states that blood meal has 

 given excellent results in horse feeding. (270-1) As such animal by- 

 products are unpalatable to horses, they must be mixed with well-liked 

 feeds. 



Velvet bean feed was found satisfactory for horses by Lindsey at 

 the Massachusetts Station 84 when forming about 18 per ct. of the con- 

 centrate mixture. (264)
