res'ulits further than body support. If we propose to fatten this same sieer, 

 we are shown by the second line of the table that the protein must be in- 

 <;reased until 2.5 pounds are given daily, and the carbohydrates run up 

 to 15 pounds and the ether extract to 0.5 pounds. The milch cow needs 

 the same protein and fat as the fattening ox, but not quite so much car- 

 bohydrates, and the horse a^t medi um work requires less nutrients than 

 the cow, excepting the ether extract. 



Please remember that this table is oinly a sample, and does not give 

 all that the school teacher would have when teaching her class. . On her 

 chart or in the text book used there would be a much larger tablie showing 

 the feed required for pigs of different ages, for the dairy cow giving dif- 

 erent quantities of milk, also^ for the sheep, etc. 



PRACTICAL APPLICATION OF TABLES. 



We have now had two tables before us for consid'eration. In the 

 first we were told how much digestible material is contained as an average 

 in several common feeding stuffs. We have been told in the second how 

 much feed different animals require for their proper support. In order 

 to apply thiS' knowledge let us endeavor to calculate a ration for the dairy 

 cow. Remember that by "ration" we mean the amount of food necessary 

 for the support of an animal one day. Further, we mean by "staindard 

 ration," just the amount of nutriment the animal requires for one day — 

 no more and no less^ — for here is where the usefulness of this line of in- 

 struction comes in. Every cow, for example, requires a certain amount 

 of food for the support and. nourishment of her body, and she must have 

 this amount before she can re/turn any profits to her owner. The amount 

 that the cow requires for merely supporting the body is about that repre- 

 sented by the ox at rest in his stall, which is gi^^en in thei second table. 

 We see that when giving 22 pound s of milk daily the cow will require more 

 than three times as much protein as the ox at rest, while s'he wdH need 13 

 pounds of carbohydrates instead of 8, as required by the ox at rest. The 

 ether extract or fat required by the cow is five times as great asi the ox 

 at rest.
