GUERNSEY COW

The important indications of good form in dual females are: (1) Medium to large size for the breed or grade. (2) Good length and depth in the coupling. (3) Good development of udder and milk veins. (4) Good constitution, as indicated by good width through the heart. (5) Head and neck inclining to long and fine. (6) Ribs of medium spring, open spaced, and covered with a good handling skin. The dual types have an absence of extreme development in the direction of either the dairy or the beef form.

In males selected for breeding, the evidences of masculinity should be markedly present. These include increased strength as shown in the head, neck, breast, shoulders, back and limbs.

The advantage of having pure blood stock over "scrubs" is apparent. For those, however, who want something better than scrubstock and cannot pay the high price which pure blood commands, the ownership of grade cattle offers a satisfactory solution of the problem.

Grading consists in mating thoroughbred sires with common females and with the female progeny for a number of generations. Where the work is wisely done by the use of good sires, accompanied by the rejection of all inferior animals for future breeding, the progeny of beef sires may be brought up to the level of the pure breed for beef making from which the sires have been selected in four generations. To bring milking qualities up to the level may call for one or two more generations of such breeding. Not only do these grade animals answer almost equally well, with pure breeds, but they may be bought for much less.

If cows are to produce a maximum return in milk, they must be kept in comfort. In winter they are usually tied in the stall. The light should be ample and the ventilation thorough. Lack of proper ventilation causes the spread of tuberculosis in cattle.

Cows must be allowed exercise, even in winter.

They should be allowed to go out daily for an hour or more into a sheltered yard, save on days when the weather is extreme; or, better still, be given the liberty of a closed and well-ventilated shed during a portion of the day. It should be supplied with a fodder rack.

In summer, cows in milk must be protected from storms, from excessive sunshine, and from flies, as far as this may be practicable. Pratts Fly Chaser is unequalled as a fly repellant. It is perfectly safe to use, does not injure or gum the hair, and is economical. A light spray is both lasting and effective.

Cows in milk should be driven gently. The pasture should not be too distant from the stable, and driving during the heat of the day should be avoided.

The quality of milk is easily injured by coming in direct contact with foreign substances or by imbibing odors. The milk must be drawn from clean udders, with clean hands, into clean pails, and amid clean surroundings. The stables must have attention. The udder and teats should be wiped off by using a damp cloth. Milking should be done with dry hands into metal pails, kept clean by scalding. Milking before feeding prevents dust particles from getting into the milk. Noxious odors are kept down by the prompt removal of droppings and by strewing sand, plaster, rock phosphate, or dry earth in the manure gutters.
