EXPERIMENTS IN PIG FEEDING. 119 



would eat in addition. After the eighth week the milk was 

 discontinued, and they were allowed all the corn-meal 

 they would eat, mixed fresh with a little water. 



During the first week the pigs consumed about 23 1 1 3 

 Ibs. each of milk, and gained 3' | 2 Ibs. each. 



Second week, they consumed 48 ibs. each of milk, and 

 gained a little over 6 Ibs. each. 



Third week, consumed 47 Ibs. milk, and gained 3 3 1 4 Ibs. 

 each. 



Fourth week, consumed 52 Ibs. milk, and gained 5 Ibs. 

 each. 



The amount of food consumed for each pound of live 

 weight of the pigs was 



1st week. 2d week. 3d week. 4th week. 



3.93 Ibs. 4.43 Ibs. 2.95 Ibs. 2.57 Ibs. 



The gain for each hundred pounds of live weight was 



1st week. 2d week. 3d week. 4Jh week. 



86.00 Ibs. 80.64 Ibs. 26.78 Ibs. 37.69 Ibs. 



The amount of food consumed to produce one pound 

 of increase was 



1st week. 2d week. 3d week. 4t?i week. 



6.53 Ibs. 7. 70 Ibs. 12.52 Ibs. 10.56 Ibs. 



These experiments, confirmed as they are by others giv- 

 ing similar results, show conclusively that a young animal 

 eats much more, in proportion to live weight, than an 

 older one. Thus, for each pound of live weight, the pigs 

 ate nearly 4 Ibs. of milk the first week, and only 2 1 | a Ibs. 

 the fourth week. It would also seem that the younger the 

 animal, the more rapidly it gains in proportion to the food 

 consumed. Thus, it required about 7 Ibs. of milk the first 

 fortnight to produce a pound of increase, and ir| a Ibs. 

 the second fortnight, or about 65 per cent more. 



So far, therefore, these results strikingly confirm the 

 conclusion we should arrive at from theoretical considera- 

 tions, that the more food an animal can eat, digest, and
