tion, all of which detracts from the desirable results to be 

 obtained from such a practice. Consequently, if the pig 

 cannot store enough protein or other nutrients to tide 

 over the time between meals, when he is fed only twice 

 per day, and thereby sets up a high factor of waste, he 

 cannot be expected to make as large gains as he would if 

 he were fed three times a day, because the material would 

 not be available for making gains in live weight. Fur- 

 thermore, after the time that all the stored material were 

 used, and before the time the next supply came from the 

 stomach, the animal would have to draw upon the fixed 

 tissue of the body to supply the functions necessary for 

 maintenance, waste, heat and energy production. This 

 would reduce the store of fixed tissue already established, 

 which would lessen the gains made during such a period. 

 The reason that feeding three times a day is more ef- 

 fective for concentrated than for bulky rations is that the 

 concentrated ration is digested more rapidly. The period 

 during which the bulky ration is digested is more ex- 

 tended and supplies the various functions of the animal 

 directly for a longer time, consequently is more nearly in 

 harmony with their demands. Feeding three times per 

 day is more advantageous with the young pig, or with the 

 pig during the growing period, than with the older pig, or 

 during the fattening period because the younger pig can 

 eat the more. He apparently can eat and digest more 

 than he can use at the time and store for future use, while 

 all that the older pig can eat is taken care of by these 

 means. 



RESULTS. 



As to the results that may be obtained with this system 

 of feeding as compared with feeding according to the 

 Wolflf-Lehmann Standard, the following may be cited:
