130 THE dairyman's MANUAL. 



The column of money values represents the food value 

 of these substances as compared with ordinary meadow 

 hay at sixty-four cents per 100 pounds, or $12.80 per 

 ton, and with the very best hay at $1.00 per 100 pounds 

 or $20.00 per ton. 



It should be explained that these values are taken 

 from the basis of the chemical composition of the sub- 

 stances ; and, as a means of comparison, the analysis and 

 comparative value of corn cobs are given, whiph on this 

 basis would seem to show them to be worth forty-one 

 cents per 100 pounds. Now no dairyman in his right 

 mind and with any experience would purchase corn cobs 

 for $8.20 per ton. Consequently, it is hardly necessary 

 to say that the- above figures are given for what they are 

 worth only, as showing the actual composition of the 

 substances mentioned, and to be used in the light of 

 common sense, reason and experience, and as compara- 

 tive only. 



The experienced feeder of cattle will not need any sug- 

 gestions in regard to the use of these foods ; he will be 

 able to select those which contain the elements he wants, 

 and which are to be procured for the least money. For 

 the benefit and use of other feeders and young dairymen 

 the following remarks upon these foods may be made. 



For the maintenance of an animal tliere is required, for 

 each 1,000 pounds of hve weight, a daily ration of twenty 

 pounds of the best hay, which contains seventeen and a 

 half pounds of dry substance, which should consist of 

 0.7 of a pound of albuminoids, eight pounds of carbo- 

 hydrates, and 0.15 of a pound of fat, or 8.85 (eight and 

 three-quarters pounds in round numbers) of digestible 

 nutritive substance. This consists of nearly twelve parts 

 of carbonaceous matters for the support of respiration 

 and of the vital heat, to one part of nitrogenous matter 

 for the repair of the muscular tissue worn out. For a 

 cow in ordinary milk there is required twenty-four
