SKIM-MILK. 121

Credit skim-milk.— If I am right in ray 

 conclusions that there is little if any profit in 

 producing 4-cent pork from 35-cent corn it will 

 be just and fair to credit skim-milk with the 

 profit that comes with feeding a combination 

 of skim-milk and grain food when the growth 

 is credited at 4 cents. When pork is worth 

 more than 4 cents, as it frequently or generally 

 is, we are on a new basis and both grain food 

 and skim-milk will receive more credit. 



Feeding sow with pigs. — In 1878 I made 

 some experiments with feeding pigs, taking a 

 litter of eight pigs and their dam when the pigs 

 were twelve days old. The dam weighed 290 

 lbs. and the eight pigs 61 lbs., making a total 

 of 351 lbs. Eighteen days later the dam 

 weighed 295 lbs. and the eight pigs 112 lbs., a 

 total weight of 407 lbs. This was a gain in 

 eighteen days of 56 lbs. worth 4 cents per 

 pound, or $2.24. .They were fed 141 lbs. of 

 corn-meal and wheat bran worth $14 per ton, 

 or 98 cents. They were also fed 530 lbs. skim- 

 milk. We will deduct from the value of the 

 increase weight ($2.24) the cost of meal and 

 bran (74 cents) and we have $1.26 for the 530 

 lbs. skim-milk, or 23 4-5 cents per 100 lbs. of 

 skim-milk.
