370 Digestibility of Matze Consumed by Swine [April-July. 



two ten-day periods, during which they were kept in cages, each 

 animal receiving throughout the periods one kind of grain, viz., 

 whole grain on the cob, dry or soaked shelled, or dry or soaked 

 ground grain, The feces produced f rom the feed eaten during the 

 ten days was distinguished by a charcoal marker given at the begin- 

 ning and end of each period. 



The averages of results obtained in all the experiments thus far 

 conducted are given for light and heavy animals respectively, in thq 

 accompanying table :

Taking dry matter as a basis for comparison, the tables indicate 

 that the light-weight swine digested whole grain on cob, and shelled 

 grain more thoroughly than did the heavy swine, while the latter 

 utilized the soaked ground grain to better advantage than the former. 

 The light swine have the highest digestion coefficient for whole 

 grain on cob, then dry shelled, dry ground, soaked shelled and 

 soaked ground grain, respectively, whereas with the heavy-weights 

 the soaked ground grain has the highest digestibility, then, success- 

 ively, dry ground, dry shelled, ear, and soaked shelled corn. 



The figures in Table i are in close agreement with those obtained
