It is not the feed, nor the body, nor the digestive tract of the cow, but the glands of her udder, which determine the characteristics of the milk yielded by each individual. After all, this is what we should expect, for if milk varied with every slight change of food and condition, the life of the young, dependent on such milk, would be in constant jeopardy. While the kind of feed given the cow does not materially change the percentage of fat in her milk, in some cases it does alter the character or nature of the fat. The fat of milk is composed of several kinds LIBERAL RATION FED TO GOOD DAIRY COW THREE-FOURTHS RATION USE OF FEED BY COWS V/,.

When fed a three-fourths ration she can uae only one-third of her feed for pro- ducing milk, and when fed a half-ration she needs all her feed to maintain her body. A beef cow, if fed a liberal ration, will turn part of her surplus feed into fat instead of milk. (After Van Norman.) of fat—palmitin, olein, stearin, butyrin, etc. When a cow is given feeds rich in vegetable oils (which contain much olein), the milk fat will then contain more olein than normal. This usually tends to make the butter softer, for olein is a liquid fat, but in some instances this tendency is offset by still other changes in the composition of the fat. Cottonseed and cocoanut meal produce firm, hard butter. A change from dry feed to pasture generally produces fat higher in olein, resulting in softer b
