 produced from whey, as indicated in the following table: 



Results of slaughter tests with pigs fed whey and skim milk — Copen-

891. Rye compared with barley. — The average of 11 experi- 

 ments, 2 with 110 animals, shows a daily gain of .865 pounds for

Results with barley and rye-fed pigs — Copenhagen Station. 



The results indicate a practical equality between the two feeds 

 for pork production. (177-8) 



While rye is shown to be of equal value with barley for pig
