THE VALUE OF BUTTERMILK AND 

 LACTIC ACID IN PIG FEEDING 



By J. B. LINDSEY and C. L. BEALS 



Condensed (semi-solid) and dried buttermilk are by-products of the 

 creamery industry, now widely advertised for use in pig feeding. An ex- 

 periment with twelve growing pigs showed that condensed (semi-solid) 

 and dried buttermilk when fed in limited amounts proved altogether too 

 expensive to warrant their use for economical pork production. The semi- 

 solid milk cost six cents and the dried article twelve cents a pound, and 

 they were fed in the diluted form to the extent of from two to four quarts 

 daily per pig. 



Two experiments with lactic acid added to the grain slop in the amounts 

 usually found in ordinary buttermilk showed no pronounced effect in pro- 

 moting appetite or in causing an increase of growth.
