372 Digestibility of Maize Consumed by SwinelApn\-Ju[y. 



tageously, then dry shelled, dry ground, ear, and soaked shelled 

 grain, successively. The soaked ground corn required the longest 

 time for traversing the ahmentary tract, then dry shelled, ear, dry 

 ground and soaked shelled, the latter two being equal in this respect. 



The above correlation between digestibility and the time during 

 which the feed remains in the alimentary canal, does not appear in 

 the results obtained from the 191 1 series of experiments ; therefore, 

 more investigation is needed along this line. 



The results obtained in our digestion trials agree fairly well, in 

 a general way, with feeding experiments which have demonstrated 

 that light hogs, weighing less than 200 Ib., make the most rapid 

 gains with whole corn on cob, in the natural State; while heavy- 

 weight swine make the most rapid gains with the soaked shelled 

 and soaked ground grain. Discrepancies in results of the different 

 experiments are explained to a great extent by the necessarily small 

 number of swine used in the digestion trials, while in the feeding 

 experiments many more animals were examined, thus eliminating the 

 factor of individuality.
