In general structure there is a marked difference between the beef and dairy breeds. This is shown in Figs. 248, 249. The beef cow is square, full over the back and loins, and straight in the back. The hips are covered evenly with flesh, the legs full and thick, the under line, or stomach line, parallel to the back line, and the neck full and short. The eye should be bright, the face short, the bones of fine texture, and the skin soft and pliable. [Illustration: FIG. 248. ABERDEEN-ANGUS COW (A BEEF TYPE)] The dairy cow is widely different from the beef cow. She shows a decided wedge shape when you look at her from front, side, or rear. The back line is crooked, the hip bones and tail bone are prominent, the thighs thin and poorly fleshed; there is no breadth to the back, as in the beef cow, and little flesh covers the shoulders; the neck is long and thin. The udder of the dairy cow is most important. It should be full but not fleshy, be well attached behind, and extend well forward. The larger the udder the more milk will be given. The skin of the dairy cow, like that of the beef breeds, should be soft and pliable and the bones fine-textured. =The Dairy Type.= Because of lack of flesh on the back, loins, and thighs, the cow of the dairy type is not profitably raised for beef, nor is the beef so good as that of the beef types. This is because in the dairy-animal food goes to produce milk rather than beef. In the same way the beef cow gives little milk, since her food goes rather to fat than to milk. For the same reasons that you do not expect a plow horse to win on the race track, you do not expect a cow of the beef type to win premiums as a milker. [Illustration: FIG. 249. JERSEY COW (A DAIRY TYPE)] "Scrub" cattle are not profitable. They mature slowly and consequently consume much food before they are able to give any return for it. Even when fattened, the fat and lean portions are not evenly distributed, and "choice cuts" are few and small. By far the cheapest method of securing a healthy and profitable herd of dairy or beef cattle is to save only the calves whose sires are pure-bred animals and whose mothers are native cows. In this way farmers of even little means can soon build up an excellent herd. =Improving Cattle.= The fact that it is not possible for every farmer to possess pure-bred cattle is no reason why he should not improve the stock he has. He can do this by using pure-bred sires that possess the qualities most to be desired. Scrub stock can be quickly improved by the continuous use of good sires. It is never wise to use grade, or cross-bred, sires, since the best qualities are not fixed in them. [Illustration: FIG. 250. HEAD OF A GALLOWAY COW]
