=Cream.= 100 pounds of 4% milk will produce: 20 pounds of 20% cream and 80 pounds of skim remaining, 13¹⁄₃ pounds of 30% cream and 86²⁄₃ lbs. of skim remaining, or 10 pounds of 40% cream and 90 pounds of skim remaining. The average cream sold tests about 30% butter-fat, so on the average the farmer has left about 86 pounds or a ten-gallon can of skim milk for every 100 pounds of 4% milk. =Skim Milk.= The value of skim milk on the farm as feed is an important one for the farmer. The price of whole milk in the city is not always high enough so that it pays the farmer to sell his skim rather than to use it for feeding. During the flush season in the spring when milk dealers are all burdened with a surplus of milk, it would be a great advantage if more farmers would separate and feed the skim milk to hogs. I will endeavor to give here as accurately as possible what real information I can gather from Experiment Station reports concerning the feeding value of skim milk. At the outset it might be well to state that on this question I have never known any two agricultural experts to agree and experiments need to be carefully analyzed before they yield true information. I can prove to you from experiments published in Henry & Morrison’s “Feeds and Feeding” that skim milk is worth only $.08 a hundred pounds when corn meal is worth $1.00 a hundred, and I can prove that skim milk is worth $.31 a hundred pounds when corn meal is worth $1.00 a hundred. In fact when an experimenter undertakes to prove a thing he has very easy sailing if he can line up conditions to suit the proposition he intends to prove. The trouble with most experiments on this subject has been that they are apparently planned to be used as arguments for the purpose of increasing the feeding of skim milk and they do not undertake to solve the real question involved.
