The Composition of American Feeding Stuffs. 



It was but a few years ago that we were obliged to depend upon 

 German analyses for a knowledge of our cattle foods, but so much 

 w^ork has lately been done in this country in the way of investigating 

 agricultural products that we are now well informed in regard to 

 the composition of many American feeding stuffs. Dr. E. H. Jen- 

 kins of the Connecticut Experiment Station has published a much 

 needed compilation of American analyses, and here follow his tables 

 as given in the report of the Connecticut Experiment Station for 

 1887. Under the head of each ingredient can be seen the minimum, 

 maximum and average percentages as found by the several analyses 

 made. For instance, in the case of protein in timothy hay, the left 

 hand column shows that fifty-three analyses have been made, and 

 the column headed i^rotein shows that the lowest percentage found 

 was 4.2, the highest 9.6, and the average 6.06.
