166 FEEDS AND FEEDING 



low in carbohydrates and fat, but carries about 20 per ct. digestible crude 

 protein, one-third of which is amids. 26 At former prices they were often 

 an economical source of protein, but since they are not relished by 

 stock, they should be given in limited quantity mixed with other con- 

 centrates. Malt sprouts are especially valuable for dairy cows, tho they 

 will not usually eat over 2 or 3 Ibs. daily. (594) In Europe horses have 

 been fed as high as 5 to 6 Ibs. per head daily with good results, and sheep 

 0.5 Ib. daily per 100 Ibs. live weight. Since malt sprouts swell greatly when 

 they absorb water, they may cause digestive disturbances if fed dry to 

 stock in large amounts and should therefore be soaked for several hours 

 before feeding. "When not over 1 Ib. per head is fed to cattle with other 

 feed, soaking is unnecessary, but moistening to lay the dust is advisable. 27 



231. Barley feed; barley bran. Barley feed is the entire mill run by- 

 product from the manufacture of pearl barley or barley flour, and in- 

 cludes the hull as well as the outer coat of the kernel. Usually there is 

 but a small amount of this feed available, but during the war, when 

 large quantities of barley were milled for flour, large amounts of barley 

 feed were sold. A good grade of barley feed, containing 11 per ct. fiber, 

 was found by Morrison, Humphrey, and Bohstedt at the Wisconsin 

 Station 28 to be worth about $42.16 per ton for dairy cows compared with 

 wheat bran at $45 per ton. For fattening pigs, barley feed was worth 

 17 per ct. less per ton than ground barley. Barley bran is rather 

 erroneously named, as it consists almost entirely of barley hulls, with 

 only a small amount of the outer coat of the kernel proper. At the Wis- 

 consin Station, barley bran containing 27 per ct. crude fiber was worth 

 only $29.56 per ton for dairy cows compared with wheat bran at $45.00. 



V. RYE AND ITS BY-PRODUCTS 



Rye, Secale cereale, the principal cereal of north Europe, is not ex- 

 tensively grown in America. Tho it repays good treatment, this " grain 

 of poverty" thrives in cool regions on land that would not give profit- 

 able returns with the other cereals. It furnishes about one-third of the 

 people of Europe with bread, and when low in price or off-grade is com- 

 monly fed to stock. (396) 



232. Rye and its by-products. Tho farm animals show no fondness for 

 rye, they take it willingly when mixed witfrother feeds, as should usually 

 be done. Fed alone or in large amounts, it is more apt to cause digestive 

 disturbances than the other cereals. In northern Europe it is a common 

 feed for horses and swine. (480, 948) Fed in large allowances to cows, 

 rye produces a hard, dry butter, but a limited amount mixed with other 

 feeds has -given good results. (581) 



The by-products in the manufacture of rye flour are rye bran and rye 

 middlings, which are usually combined and sold as rye feed. All have 

 about the same feeding value as the corresponding wheat feeds, each con-
