206 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



375 pounds meal and 34 pounds tankage. 



390 pounds meal and 727 pounds skim-milk. 



The pigs getting tankage ate their feed quite as eagerly as 

 those getting skim-milk, and continued thrifty throughout the 

 experiment. 



Tankage, therefore, proved a very satisfactory substitute, 

 so far as gains in weight were concerned, but, when skim-milk 

 can be obtained at 15 cents per hundredweight, it is cheaper 

 than tankage at prevailing prices. 



In other experiments by the writer, the results of which 

 have not been published, other substances, such as linseed meal, 

 " black-strap " molasses, and tea from alfalfa hay, have been 

 tried, but none of these approached tankage in efficiency a's a 

 substitute for skim-milk for young pigs. 



The Michigan Experiment Station also compared tankage 

 with skim-milk for young pigs. The pigs on skim-milk made 

 slightly larger gain's, but, when skim-milk was valued at 20 

 cents per 100 pounds and tankage at $1.6 2% per 100 pounds, 

 the tankage-fed pigs made cheaper gains than the skim-milk 

 pigs. 



REVIEW, 



1. Give the average equivalent of roots for 100 pounds meal. What 

 kind of roots are best? 



2. Give the meal equivalent for potatoes. How are they to be fed? 



3. Tell of the value of pumpkins for swine. How may they be fed? 



4. Tell of the suitability and value of apples for swine. 



5. How does the proportion of skim-milk fed affect its meal equivalent? 

 Give the average. 



6. How do sweet and sour skim-milk compare as feed for pigs? 



7. What is the meal equivalent of whey? Is there danger in letting 

 it sour? 



8. What is separated whey? How does it compare with ordinary 

 whey? 



9. How does buttermilk compare with skim-milk for pigs? 



10. Mention some of the best substitutes for skim-milk for pigs.
