CATTLE FEEDING. 14]^ 



WJieat bran is well digested b}' ruminants — 78 per cent, of the 

 albniiiinoids and 82 per cent, of the extractive carbohydrates being 

 digested. 



Corn. Eight^'-foiir per cent, of the albuminoids and 93 per cent, 

 of the extractive carbohydrates of corn are digested. The per- 

 centage of albuminoids is lower than in the cereals, and it is well to 

 add to it a supplementarj^ food, rich in nitrogenized compounds. 

 Corn contains as much as 5 to 9 per cent, of fatty substance, which 

 renders it valuable in fattening. 



Brewery Slump. It contains about 24 per cent, of dry matter 

 which is rich in albuminoids. 



Bean meal is quite rich in albuminoids, and is often useful as a 

 supplementar}- food to increase the quantity of nitrogen in a ration 

 which is deficient in albuminoids. About 90 per cent, of the albu- 

 minoids are digestible, and 95 per cent, of the extractive carbo- 

 hydrates. 



Lupins are very rich in albuminods, containing 32 to 43 per cent. 

 They are not, however, generally I'elished by cattle on account of a 

 bitter principle which the}' contain. 



Cake of the Oleaginous Gh'ains. On account of the high com- 

 mercial value of oleaginous grains, they are not, with the exception 

 of cotton seed cake, much used as a part of fodder for cattle, though 

 experiment has repeatedl}^ proved their great value as an addition 

 to fodder poor in fats. As before noticed, the amount of fatty or 

 oily substance must not be too large if we wish to avoid any disturb- 

 ance in the digestive process of cattle. 



Linseed Cake. The digestibilty of the albuminoids is 84 per cent., 

 fats 89 per cent., and extractive carbohj-drates 78 per cent. These 

 are the results of experiments in feeding tried at Hohenheim upon 

 sheep, at Halle upon goats, and at Mockern upon oxen. 



Rape-seed Cake. Experiments tried at Dresden with sheep, and 

 at Mockern with cows, gave the albuminoids a digestibility of 80 

 per cent., as also to the extractive carbohydrates. More recent ex- 

 periments with oxen at Mockern gave 8G per cent, for albuminoids, 

 and 75 pfer cent, for extractive carbohydrates. 



Cottonseed Cake. The digestibility of the albuminoids is 74 per 

 cent., and 46 per cent, for the extractive carbohydrates, as deter- 

 mined by experiments upon sheep at Hohenheim.
