and are called albuminoids or flesh formers ; of materials that go to 

 support heat and perhaps to make fat, called carboh3-drates ; of 

 materials that go to make fat and heat, called fats or oils. The fact 

 that interests us the most is that the heat producers or carbohydrates, 

 or fats can not produce flesh, and that an animal can not grow unless 

 flesh is produced, and that some foods are quite deficient in flesh 

 makers, like sti'aw, corn fodder and swale hay, while others have an 

 excess of flesh formers, like bran, cotton seed meal, blood, fish and 

 oil cake meal. German investigators have told us that growing 

 cattle require 14 lbs. of digestible flesh formers per day for a 700 lb. 

 beast, for best results. I find that I cannot induce such an animal 

 to consume over 13 lbs. per day of straw. This would contain, by 

 the same authorities, only .18 lbs., or but barel}' ^ of the quantity 

 required. The animal would have to consume 100 lbs. in order to 

 get flesh formers enough. I have had samples of cotton seed meal 

 that would give 1.4 lbs of flesh formers for 4 lbs. of the meal, or when 

 fed with the oat straw 3 lbs. would make a well-balanced ration. 



Presuming that the facts in full will be presented to you, with 

 digestion tables, &c., I pass the subject with a brief review of a 

 table of one winter's feeding trials, of the four made b}' me at our 

 College Farm. 



The swale ha^', ground meal and cotton seed meal were analyzed 

 b}' Prof. Collier of Department of Agriculture at AVashiugton, and 

 the good hay by Prof. Johnson of the Connecticut Experiment 

 Station. 



I have resorted to Wolff"s tables for my computations relating to 

 the other foods used :
