TEST NO. 3. 



Digester Tankage vs. Skim Milk for Growing Swine BeUoeen 50 amd 



120 Days of Age. 



In this test the ration for Lot \ w^as made up in the following pro- 

 portions by weight, viz. : Middlings 20 pounds, corn meal 10 pounds, 

 and digester tankage 3 pounds; the tankage formed one-eleventh of the 

 mixture. This ration was made into a slop by adding water. Lot VI 

 was fed a ration of the following proportions, viz. : Middlings 20 pounds, 

 corn meal 10 pounds and skim milk 90 pounds, three pounds of skim 

 milk being used to every pound of meal juixture. These rations dupli- 

 cate those of Test No. 2. 



The pigs used in this test were the offspring of a Berkshire boar 

 and Tamworth sow and were farrowed March 27, 1905. There were 

 twelve pigs in the litter and ten were raised. On May 16th, when these 

 pigs were 50 days old, about weaning time, they were divided into two 

 lots of five each, there being two barrows and three sows in each pen. 



•The results of this test are summed up in the following table. 



During the 70 days of this test the five pigs of Lot Y consumed 

 on an average 2.6G pounds meal mixture per head daily, while increas- 

 ing in live weight from 3G.6 pounds to 95.6 pounds at the rate of .84 

 pounds per head daily. At the same time the five pigs of Lot VI con- 

 sumed on an average 2.25 pounds meal mixture and 6.75 pounds skim 

 milk per head daily, while increasing in live weight from 36.8 pounds to 

 104.6 pounds at the rate of .96 pounds per head daily. The results 

 of this test agree exactly with those of test 2. Where skim milk was 

 fed in this case the gains were slightly larger, but the cost of produc- 

 tion where tankage was used was 38 cents less per cwt. gain. 



CHECK TEST. 



A check test was conducted for ten weeks, in which two lots of pigs 

 of five each were fed on a ration consisting of middlings 2 parts and 

 corn meal one part, made into a thick slop by adding water. Attention 

 is called to the fact that this ration duplicates those of the previous 

 tests, in-so-far as it contains middlings and corn meal in the same propor-
