336 ON THE MILK OF THE COW. 



Analysis of the ash of coto manure, from hrewer^ screenings and oil cake. 



Screenings. Oil cake. 



Potash 4-44 862 



Soda 7-20 1-SO 



Earthy phosphates 22*63 27-10 



• Carbonate of lime 2-01 2-20 



Magnesia , 1-07 1-41 



Silica 56-90 58-10 



Sulphuric acid, 8-62 2-00 



Chlorine 0-21 0-20 



The oil cake upon which the animal fed contained a very large percentage of silica, or sand, 

 and hence gave quite a large product in the excrement. The excrement of the horse contains 

 of dry matter 21, and of water 79 per cent ; matter soluble in alcohol, • 35 ; wax, or resin, • 67 : 

 ash of the 21 per cent 1-8, loss -03. The excrement of the cow, when fed upon oil cake, 

 contained water 73-80; of dry matter when dried at 212=, 26-20. 



I made the following analysis of provender, made of Indian corn one part and oats two parts, 

 and rye middlings ; both are used largely for feeding horses : 



Provender. Rye middlings. 



Starch, 36-90 35-48 



Oil and gluten, 1-40 1-70 



Albumen, 2-90 7-12 



Dextrine,; 1-80 7- 15 



Sugar, 8-90 14-80 



Fibre, 33-50 17-40 



Water, 13-30 0-00 



In the analysis of the rye middlings the water was not determined, but in the cereals it does 

 not vary much from fourteen per cent. From these analyses, rye middlings contains more 

 nutriment than provender composed of one bushel of corn and two bushels of oats : the 

 amount of fibre is large in the provender, being about twice as large as in the rye middlings : 

 the albumen and dextrine is much greater in the rye than in the provender. Those who have 

 used rye middlings for horses, speak favorably of it as a kind of food for them. For myself, I 

 have never seen better results from the food for a horse than twelve quarts of oats per day, 

 especially if given regularly, and at stated hours. The latter condition is indispensable in 

 the feeding of all kinds of animals. Nature has her periods : periodicity is one of her laws. 

 A farmer who is precise in his observance of this law, in dispensing his food to his cattle, will 

 possess fine flocks and herds ; while he who disregards this law will be unable to exhibit fine 

 stock, no matter how much and what he feeds them.
