882. Skim milk fed alone. At the Connecticut (Storrs) Station 1 

 Beach fed 25-lb. pigs on separator skim milk alone and in combina- 

 tion with grain during an 86-day trial with the following results : 



Feeding separator skim milk alone and in combination with grain. 



This trial shows the great loss from feeding even young pigs en- 

 tirely on skim milk, for when so fed they required over 2,700 Ibs. 

 of milk for 100 Ibs. of gain. By feeding meal with the milk far more 

 rapid and economical gains were made. Skim milk, rich in protein 

 and mineral matter, should always be combined with starchy carbo- 

 hydrates, such as corn, barley, kafir, milo, etc., in which case it be- 

 comes one of the most useful of all available feeds for the pig. (302) 



883. Meal value of separator skim milk. Fjord at the Copen- 

 hagen (Denmark) Station, 2 Grisdale at the Ottawa Experimental 

 Farms, 3 Linfield at the Utah Station, 4 and the author at the Wis- 

 consin Station, 5 found the average feeding value of separator skim 

 milk, when given in combination with corn meal or meal of the 

 mixed grains, to be as follows: 



The Copenhagen (Denmark) Experiment Station _. 600 pounds 



The Ottawa (Canada) Experimental Farms 604 pounds 



The Utah Experiment Station 495 pounds 



The Wisconsin Experiment Station _ 475 pounds 



The Wisconsin trials were usually with quite young pigs, thereby 

 giving a higher value to the milk than would have been obtained 

 with older animals. It is shown that, when properly combined with 

 concentrates, from 500 to 600 Ibs. of separator skim milk has a feed- 

 ing value for pigs equal to 100 Ibs. of corn meal or mixed meal. 



884. Proper ratio of milk to meal. At the Wisconsin Station 6 the 

 author conducted 19 feeding trials with 88 pigs of all ages to de- 

 termine the value of separator skim milk when fed in combination 

 with varying amounts of corn meal. For convenience the results 

 are arranged in groups, the first comprising trials in which not over
