FEEDING METHODS.

chiefly from Prof. Stewart's valuable work on 

 "Feeding Animals," and by him drawn mainly 

 from the experiments of Prof. Johnson and Dr. 

 Wolff. He takes as a ration for an average 

 milch cow, estimated for 1,000 pounds live 

 weight, a combination that will contain twenty- 

 four pounds of dry organic substance. This 

 ration should contain of digestible nutrients: 

 albuminoids, two and five-tenths pounds (2.5 

 Ibs.); carbo-hydrates, twelve and five-tenths 

 pounds (12.5 Ibs.); fat, four-tenths of a pound 

 (0.4) ; making a total of fifteen and four-tenths 

 (15.4) pounds in the whole ration of twenty- 

 four pounds. The actual weight of the ration 

 will of course be considerably in excess of this 

 owing to the water, which is not calculated. 

 Thus to get twenty-four pounds of dry matter 

 in young clover hay about twenty-five per cent 

 would have to be added, making say thirty 

 pounds. In such food as mangolds, brewers' 

 grain, etc., a much larger allowance must be 

 made for water, amounting to from seventy- 

 five to as much as eighty-five per cent. The 

 richest and best meadow hay approximates 

 closely the theoretical standard, as may be 

 seen by the following table of analysis (esti- 

 mated on basis of 1,000 Ibs. live weight):
