Feeds and Feeding. 



From tMs table we learn that wheat straw contains 5. 9 ponnds 

 of nitrogen, and timothy hay more than twice as much, or 12.6 

 pounds. Clover hay is richer than timothy hay in nitrogen, and 

 especially in potash, though poorer in phosphoric acid. We 

 observe a larger quantity of all the fertilizing constituents, espe- 

 cially phosphoric acid and potash, in wheat bran than in the wheat 

 grain, from which bran is derived. This is because the starchy 

 part of the wheat grain used for flour holds little fertility, whUe 

 the outside portion of the grain which goes into the bran contains 

 most of the nitrogen and ash. 



413. Amount of excrement voided by farm animals. — Information 

 on this subject from American experiments is quite limited, but 

 the following will prove useful: 



Voidings per day of twenty-four hours by farm, emimals as deter- 

 mined at several Stations. 



The table shows that the voidings of the horse amount to over 

 55 pounds, the cow 68, the sheep nearly 4, and the pig over 7 

 pounds each 24 hours. 



416. Manure from the ox. — At the Ontario Agricultural Col- 

 lege, ^ an ox was confined from birth to maturity in a large box- 

 stall having a cement floor. The stall was weU bedded, and the 

 animal given exercise by leading, when required. Account was 



Ilept. 1893.
