EXPERIMENT STATION RECORD. 



A second experiment, which was begun in January, 1895, and lasted 

 5 weeks, was made with 10 lots of 7 pigs each. The objects were to 

 test the value of skim milk, and to compare sweet and sour skim milk, 

 corn and wheat, and feeding indoors and out of doors. Lot 8 was fed 

 sour skim milk, and all the other lots sweet skim milk. In addition, 

 lots 3 to 10, inclusive, were fed corn meal, or a mixture of corn meal 

 with bran, wheat meal, or middlings. 



Lot 5 was fed indoors and lot 10 out of doors. The financial state- 

 ment is based on corn meal at $16, wheat meal at $20, bran at $11, 

 and middlings at $15 per ton. The results of the experiment are 

 shown in the following table : 



The pigs were sold for $3.80 per 100 lbs., yielding a profit of from 

 $3.76 to $17.33 per lot. The following conclusions were reached: 



"(1) The average returns per 100 ll)s. for the skim milk, the prices for live pork 

 and for grain feeds being as given, was 22.68 cts. 



"(2) While skim milk fed alone to young pigs will support life and make them 

 grow, it is much more economical to mix with it middlings and corn meal. 



" (3) The better and more economical gains were invariably made with the smaller 

 pigs. . . . 



"(4) In this test sweet skim milk gave better returns than sour. 



"(5) Wheat bran when soaked in skim milk is readily eaten by pigs, but does not 

 seem so well adapted to form a part of their ration. It is too coarse and bulky. 

 Although in this test it was fed with a less proportion of skim milk than was allowed 

 the pens fed corn meal and milk, and therefore the conditions are not precisely 

 identical, still the excess of dry matter required to produce a pound of gain is sig- 

 nificant. 



"(6) Wheat meal forms a very acceptable addition to the ration of young pigs, 

 and can be economically used when its price per pound is not greater than corn, 



"(7) Middlings and corn meal, with sweet skim milk, produced the greatest gains 

 in proportion to the amount of dry matter consumed of any combination tested in 

 this series. It was fed to the smallest pigs and was mixed with a larger proportion 

 of milk, factors that must be taken into consideration. Still the fact that it required 

 but 1.89 lbs. of dry matter to make a pound of gain shows clearly tbe value of the 

 feed."
