The Feeding Value of Apple Pomace* 



BY J. B. LINDSEY. 



There is often considerable discussion in the agricultural press 

 and among farmers concerning the value of apple pomace as a 

 food for dairy and beef cattle. With a view to getting some 

 positive data, this station instituted a number of experiments, the 

 results of which are here briefly stated. 



It will be seen from the above figures that apple pomace is a 

 carbohydrate feed similar to corn silage. It contains about the 

 same amount of water, rather less protein and fiber, and a larger 

 proportion of extract matter. Whether the extract or starchy 

 matter in the pomace is as valuable, pound for pound, as that 

 contained in the com, has not been thoroughly demonstrated. 



(h) Digestibility of Apple Pomace. 



The value of a feed cannot always be measured by its composi- 

 tion. A food is valuable as a source of nutrition only in so far as 

 its various constituents can be digested and assimilated. This 

 station has made two different experiments to ascertain the diges- 

 tibility of the pomace, and the detailed results are to be found in 

 the seventeenth report of this station. The summary follows:
