78 SCIENTIFIC FEEDING OF ANIMALS 



tion, were found at the beginning of the experiment 

 to weigh 99-36, 99-60, 96-60 kilograms respectively. 

 The pig weighing 99-36 kilos was then killed and 

 analysed. The other two pigs received husked 

 rice as food for 75 and 82 days respectively, and 

 gained during that time 39-07 and 38-76 kilos. At 

 the end of the feeding period a chemical analysis 

 of the animals was made, and the results compared 

 with those obtained before the experiment began. 

 In this way a direct determination of the increase 

 of flesh and fat from the rice was made. The 

 quantity of protein, fat, and carbohydrates in the 

 food which had been digested was also determined. 



The average amount of fat made by the 



animal from the rice was . . . 16-13 kg. 

 The amount of fat in the food was . . 0-32 kg. 



Newly formed fat 15-81 kg. 

 5-32 kg. of food protein were split up 

 which, according to Henneberg's calcu- 

 lation (p. 65), could yield in the most 

 favourable case . . . . 273 kg. 



The amount of fat which has come from 



the carbohydrates is at least . . 13*08 kg. 



Thus it is seen that the pigs formed four times 

 more fat than could be got from the fat of the food
