TABLE VI. NET ENERGY VALTTES OF FEEDING STUFFS FOR RUMINANTS 



For the convenience of those desiring to compute rations in accordance with the 

 Armsby Feeding Standards (171-7), the following table is given. This includes most of 

 the net energy values for ruminants computed by Armsby with the special permission 

 of the authors of this volume, from the average content of digestible nutrients given in 

 Appendix Table III of this book. The figures for dry matter and digestible crude protein 

 are taken directly from Appendix Table III of this book, while those for digestible true 

 protein were computed by Armsby from the figures for digestible crude protein and 

 other data. The net energy values of a few of the important feeds for horses are given 

 on Page 287. But little reliable data of this sort is available for swine. 



It should be borne hi mind that the Armsby feeding standards are based on digestible 

 true protein, instead of digestible crude protein. Thus these standards ignore the value 

 of the "amids" in feeding stuffs as nitrogenous nutrients for the repair or growth of the 

 protein tissues of the body, or for the production of the proteins in milk. As has been 

 pointed out, this is not in accord with the results of the recent investigations with 

 reference to the nutritive value of the nitrogenous compounds of feeds. (94)
