Fattening Pigs in the Dry Lot 251 



The pigs fed whey gained faster and required less meal 

 for a given gain than did those given the meal mixture 

 alone. The results also show that sour whey was as 

 valuable as sweet. 



The quantity of whey required to replace 1 pound of 

 concentrates in the production of gains with fattening 

 pigs has been determined by Day 1 at the Ontario Agri- 

 cultural College and Henry 2 at the Wisconsin Experiment 

 Station. The figure obtained at the Ontario Station is 

 the average result of three trials in which 2j to 6 pounds 

 of whey were fed with each pound of a meal mixture 

 containing 50 per cent of shorts. The result at the 

 Wisconsin station is the average of ten trials in which 

 2 to 10 pounds of whey were fed with each pound of 

 combination of equal parts corn-meal and shorts. At 

 the Ontario Station, 9.88 pounds of whey were required 

 to replace 1 pound of meal. At the Wisconsin Station, 

 7.58 pounds of whey were required to replace 1 pound 

 of meal. 



The whey used in the Wisconsin trials was reported to 

 contain more than the average percentage of butter-fat, 

 which accounts for its higher value. As reported by 

 Henry and Morrison, 3 pig-feeding experiments conducted 

 at the Copenhagen, Denmark, Experiment Station give 

 12 pounds of whey the value of 1 pound of mixed grain. 

 Since 4.18 pounds of skim-milk or buttermilk was shown 

 to be equivalent to 1 pound of corn, it would seem that 

 whey has less than one-half the feeding value of skim- 

 milk or buttermilk. 



Two experiments by Day with fattening pigs, covering 

 periods of 104 and 90 days, showed that ordinary whey
