It should be borne in mind that the above figures express 

 only net energy and not protein value. If protein is needed 

 to balance the ration, it can be purchased most economically 

 in the high-grade protein concentrates, such as cottonseed meal, 

 gluten meal, gluten feed, distillers' dried grains and the like. 



4. Nutritive Ratio of Cattle Feeds. 



The numerical relation which the digestible protein bears 

 to the other digestible organic nutrients (fiber, extract matter 

 and fat^) is termed the nutritive ratio of the feed or ration. 

 Timothy hay has, for example, 3 parts of digestible protein to 

 47.3 parts of other nutrients, or as 1 is to 15.8. This is termed 

 a very wide nutritive ratio. Gluten feed contains 22.3 parts 

 of digestible protein to 58.6 parts of other nutrients or as 1 is 

 to 2.6. This may be termed a very narrow nutritive ratio or 

 proportion. All feeds having a nutritive ratio of 1 to 5 or less 

 may be said to have narrow ratios, those from 1 to 5 to 1 to 8 a 

 medium ratio, and above 1 to 8 a wide ratio. 



1 The fat is converted into the energy equivalent of the starch or fiber by multiplying 

 by 2.2; thus, 3 per cent of fat would have an energy equivalent of 6.6 per cent or parts of starch.
