FEEDING ANIMALS. 



and to round out into lines of beauty and harmony the 

 whole animal ; and if we would study the open secrets 

 of Nature in her dealings with the young animal, we must 

 look into the combination of elements in milk. The fol- 

 lowing is an average of the composition of the milk of the 

 cow, mare and ewe : 



It will be observed that each of these analyses shows 

 food rich in nitrogen, or muscle-forming nutriment. The 

 calf receives food in the nutritive proportion of one of 

 nitrogenous to 3.37 of carbonaceous elements. Liebig 



"The young animal receives, in the form of caseine 

 (cheese), the chief constituent of the mother's blood. To 

 convert caseine into blood, no foreign substance is required, 

 and in the conversion of the mother's blood into caseine no 

 elements of the constituents of the blood have been sepa- 

 rated. When chemically examined, caseine is fpund to 

 contain a very large proportion of the earth of bones, and 

 that in a very soluble form, capable of reaching every part 

 of the body." 



This shows clearly the great office performed by caseine 

 in the growth of the young animal. It furnishes the 

 nitrogen in the formation of the muscles, nerves, brain, 

 skin, hair, hoofs and horns, and furnishes it in so soluble a 

 form that it can reach every part of the body. J. F. W. 

 Johnston gives two analyses of the ash in 1,000 pounds of 

 milk:
