1 The carbohydrate includes the fat with its usual fuel value (2J times carbohydrate in Tables V 

 and VI). Reference: Table III, Digestible nutrients and fertilizing constituents, Henry's "Feeds and 

 Feeding." 



The use of Tables I and II in balancing rations is illustrated in 

 the following examples: 



1. How much cottonseed meal is required to balance a dairy 

 ration consisting of 30 pounds corn silage, 10 pounds alfalfa hay, 

 and 3 pounds corn meal, giving a nutritive ratio of 1:6?
