Miscellaneous Feeding Stuffs. 229 



show that buttermilk has about the same feeding value as skim 

 milk with pigs. In the hands of skilled feeders buttermilk may 

 also be used in calf rearing, though many have failed in this un- 

 dertaking. Except for very young animals buttermilk may be 

 used successfully wherever skim milk is employed as a feed. 

 Creameries often dilute buttermilk with water, thereby reducing 

 its value. (872) 



359. Whey. Whey is an exceedingly thin food, and is so liable 

 to misuse that many prefer to waste it rather than incur the risk 

 attendant upon its use. Whey may be fed to pigs with profit, but 

 it must be kept in clean vessels and fed in a cleanly manner. At 

 the Ontario Agricultural College, l Day secured as good results 

 with whey somewhat soured as with sweet whey. The feeder 

 should not conclude from this that sour whey held in filthy tanks 

 and vessels is a suitable feed for farm stock. (523, 528, 660, 873, 

 887,889,890) 



360. Fertilizing value. The dairyman who sells butter and 

 feeds the skim milk and buttermilk to farm animals parts with but 

 an insignificant amount of fertility. When cheese is made, if the 

 whey is returned to the farm, a considerable portion of the min- 

 eral matter of the milk is conserved, but most of the nitrogen is 

 lost. If whole milk is sold, the drain of fertilizing matter is con- 

 siderable. These differences should always be borne in mind in 

 conducting the various branches of dairy farming. 



V. Condimental Foods. 



361. Findings of investigators. Proprietary articles styled 

 " Prepared Food, 77 "Seed Meal," etc., costing from three to ten 

 cents per pound, are common, and judging from the advertising 

 space given them in newspapers a large amount of money must 

 be received from their sale each year. It is generally claimed 

 for these feeds that they possess great nutritive properties and 

 medicinal qualities combined. 



In England Thorley's Food is a standard article of this class, 

 having been largely advertised for many years. Lawes and Gil- 

 bert tested its effectiveness with sheep, and conclude: 2 "The
