that variations from them are some times profitable is well known 

 and from the work that has been done in our own country it would 

 seem that the proportion of non- albuminoids (starch, sugar; 

 fat etc.,) to albuminoids might well be made less than the tables 

 . indicate,^ but the fact that we may depart in a small way from 

 these tables does not ih the least reduce their value tvs, guides to 

 good feeding. 



The column headed digestible albuminoids includes that part 

 of the food which contains the nitrogen of the plant. It will 

 be noticed that the per cent of albuminoids vary greatly in dif- 

 ferent fodders. In dry fodders, oat straw has only 1.45 pounds 

 in a hundred while cottonseed meal has 31.36. Hay and the 

 dry fodders commonly found on the farm have about 5% of di- 

 gestible albuminoids while the grains and concentrated feeding 

 stuffs run from 7 to 35%. It must be remembered that this 

 part of the food is very valuable, for the muscle of the growing 

 animal, the casein or curd of the milk, wool, feathers, hair, etc., 

 must be formed from the albuminoids of the food. Neither 

 starch, sugar nor oil can be converted into muscle or casein 

 by the animal. It is also believed that the fat in the milk or 

 the other fat in the body comes quite largely from the albumi- 

 noids, but fat may also come from the starch, sugar, and oil of 

 the food. The column marked "digestible non-albuminoids" 

 includes the starch, sugar, and fiber, plus the fat, multiplied by 

 2^, for it is assumed that one pound of fat is equal in nutritive 

 value to zy^ pounds of starch, by this arrangement we get the. 

 whole of the nutritive matter of the food grouped in two parts. 

 The third column shows the ratio of nou-albuminoids to albumi- 

 noids for example corn meal has 7.78% of albuminoids and 

 71.6% of non-albuminoids the " nutritive ratio " is i : 9.2 which 

 is the same as saying that for every pound of the former, there 

 are 9.2 pounds of starch, sugar, and fat (non-albuminoids). 



In these tables then we have the means of finding the 

 amount of nutritive matter require daily by any animal; the 

 live weight of any animal being known we have only to look in 

 table 1, and find the corresponding kind of animal, the table 

 will show what would be required if the live weight vere loos 

 lbs., from this we find the amount necessary for any weight by 

 multiplying that necessary for 1000 by the weight under con- 

 sideration and remove the decimal point three places to ihe left.
