products, as for the straight by-products such as hominy meal,

The dairyman should consider protein and digestibility as 

 prime factors in the purchase of commercial feeding stuffs: — pro- 

 tein, because the crops ordinarily grown are deficient in this im- 

 portant constituent, and digestibility, because the coarse fodders 

 necessary to ruminants but of low digestibility and rich in fiber 

 can be more cheaply grown on the farm, or if not can be purchased 

 for one-half to two-thirds the price of concentrates. 



While we are unable to report on the digestibility of all com- 

 mercial feeding stuffs, their fiber content is a reasonably good 

 indication of their digestibility, and feeding stuffs containing over 

 9 or 10 per cent of fiber are to be avoided unless sold at a price 

 commensurate with their true feeding value. 



While the horse and growing stock do not have the protein 

 requirements of the milch cow, the preceding remarks in the main 

 hold true where work or growth are the ends sought.
