what amount of albuminoids and non-albuminoids will be re- 

 quired daily ? Table I, shows that cows giving milk require 2.5 

 lbs., of albuminoids and 13.5 lbs., of non albuminoids daily 

 per looo lbs., 2.5 X 1^85=: 2962.5 remove point three places to 

 the left = 2.96 lbs., of albuminoids required. 13.5 X 1185 = 

 15997.5 remove point three places^ iS-99 lbs., non-albuminoids 

 required. The same rule applied under any condition or for 

 any weight will give " amount required." 



The second step is to select from table II such fodders 

 and grains as will give this amount, here is where the skill of 

 the feeder is required in selecting a suitable variety. If hay is 

 the foundation use i >^ % of the live weight of the animal of 

 hay, that is for a loao lb., animal use about 15 lbs., of hay, and 

 in addition to this 1% or 10 lbs., of any coarse fodder like corn 

 stover (corn stalks from which ears have baen husked) well cur- 

 ed straw, rye cut for fodder, millet, or bean vines. 



Where Ensilage is to be fed, take 5% of the live weight of 

 the animal of Ensilage that is for a looo lb., animal, 50 lbs., 

 and add to this ^ % or 5 lbs,, of coarse fodder, these two com- 

 binations may be regarded as foundations to which the grain 

 ration is to be fitted. Our coarse fodders, hay and ensilage, all 

 with two or three exceptions, contain much too large a percent- 

 age of non-albuminoids to meet the requirements of cows. 

 Oat straw has 30 lbs., of digestible non albuminoids to 

 I of albuminoids, (see third column table II) cornfodder has a 

 " nutritive ratio " of 19' bog meadow, or swale hay 20. Hedrsgrass 

 14, red top 10, millet 9.7 etc., now from table I, we see, leaving 

 out animals standing idle, that our different domesticated ani- 

 mals require from 5.4 to 9 pounds of non albuminoids to i of al- 

 buminoids, here is where the tables show us the deficiency of 

 such fodders ; To make good this deficiency we must look for 

 soms mxteriil th it his an excess of the albmninoUs ; running 

 down column three in table II, linseed, cotton seed, shorts* 

 middlings and gluten are seen to have nutritive ratios as follows 

 respectively, 1.5, 1.3, 4, 4.3, 2.4 now here are a class of foods as 

 much too rich in the muscle producing par^ of the food as the 

 coarse fodders and hay are too poor hence a judicious mixture 

 of one set with the other will correct the deficiencies of each 

 but how shall we know the proportion in which to mix them. 

 We have seen that a cow weighing 1000 lbs. giving milk requires 

 daily the following :
