Every one knows that corn alone is too unbalanced a ration to feed to hogs profitably. Where it is endeavored to show that skim milk has a very high value, one bunch of hogs is fed corn alone, and to compare with it another bunch is fed corn and a small amount of skim milk. Let those who are satisfied with the information that can be obtained by such an experiment use it and I will have no dispute with them. But for most of us the question is whether we should feed alfalfa to the cow and the cow’s milk to the pig or let the pig eat his own alfalfa. A hog’s ration may be balanced with alfalfa hay or with alfalfa or rape pasture. The question is whether milk and corn makes as cheap a gain as alfalfa and corn. It is very difficult to find experiments that answer this question and it is the most practical one in the world. If it is good sense to use the cost of producing pork on dry corn alone as the basis of getting at the value of milk, it is also good sense to use skim milk alone as the basis of figuring the value of grain. In an experiment published by Henry & Morrison on page 597, where little pigs weighing only twenty-five pounds were used and which are capable of making cheaper gains on milk than older hogs because they have smaller bodies to maintain, it took 2,739 pounds of skim milk to make one hundred pounds of gain. But where 233 pounds of grain were fed with 935 pounds of skim milk there was also a gain of one hundred pounds. Figuring now as they do who would set the value of milk by the cost of feeding dry grain, we will use skim milk as a basis of figuring. If skim milk is worth $.30 a hundred, corn is worth $2.32 a hundred. This is the same line of reasoning as is used when in an experiment reported on page 598, if corn is worth $.01 a pound we find that skim milk is worth $.30 a hundred. All they prove is that a hog must have something besides corn or milk. Corn is the cheapest hog feed but it is too unbalanced a diet to get the best results when fed alone. A small amount of skim milk or something else will balance the diet. According to reports published by Henry & Morrison on page 598 it will be noticed that 585 pounds of skim milk reduced the amount of grain required to produce 100 lb. growth by 179 pounds. If corn is worth $.01 a pound and we figure on that basis, skim milk is worth $.31 a hundred pounds. But notice what happens when the amount of skim milk is increased beyond what is needed to supply the elements which corn lacks. When the amount of skim milk is increased by 463 pounds more, the amount of corn meal eaten was only reduced by 56 pounds, so that for the first 585 pounds the farmer was getting $.31 but for the next 463 pounds he was getting only $.12 a hundred pounds, and when the skim milk was again increased by 849 pounds the amount of corn meal required was only reduced 71 pounds and this figures down the last batch of skim to only about $.08 per hundred pounds.
