Record of Feeds consumed and of Growth {Potinds). 



1 Sick for three days. 



Pigs 1 and 2 had the advantage in that they were fed corn meal and 

 skim milk when very young. Pigs 3, 4, 5 and 6 were fed different grain 

 mixtures when too young and did not get as good a start. Pig 3 was badly 

 out of condition and did not recuperate until August. Pigs 1 and 2 were 

 normal in every way, and on the diet of corn feed meal and digester tank- 

 age for 101 days gained daily 1.27 pounds and produced 100 pounds of 

 live weight for 322 pounds of dry matter fed. Pigs 3 and 4, on the diet 

 of corn feed meal, velvet bean feed and alfalfa, and pigs 5 and 6, on a corn 

 feed and velvet bean feed diet, gained noticeably less. All appeared 

 healthy during the experiment, and ate well. Pigs 5 and 6 did not grow 

 quite as well as pigs 3 and 4, and did not appear to be building out as 

 good a framework. It seemed evident that the alfalfa was furnishing 

 something in promoting earlj^ growth that was lacking in the diet fed 

 pigs 5 and 6. 



Although the experiment was not as satisfactory as one could wish, it 

 at least indicated that so large an amount of velvet bean feed was not desir- 

 able in the daily diet, and that it was not a satisfactory substitute for 

 digester tankage. 



Experiment II. — June 9-November 1. 



Six pigs, grade Chester White, weighing from 24 to 34 pounds each, were 

 divided into lots of two each and fed on three different rations, two of 

 which contained 20 per cent velvet bean feed in order to test its efficacy as 

 a component of a grain mixture. 



Lot I received by weight a mixture of 80 pounds of corn meal, 10 pounds 

 of digester tankage and 10 pounds of ground alfalfa.
