DAIRY


includes all that concerns its production and treatment, constitutes a most important branch of husbandry. The physical conditions of the different countries of the world have determined in each case the most suitable animal for dairy purposes. The Laplander obtains his supplies of milk from his rein-deer, the roving Tatar from his mares, and the Bedouin of the desert from his camels. In the temperate regions of the earth many pastoral tribes subsist mainly upon the milk of the sheep. In some rocky regions the goat is invaluable as a milk-yielder; and the buffalo is equally so amid the swamps and jungles of tropical climates. The milking of ewes was once a common practice in Great Britain; but it has fallen into disuse because of its hurtful effects upon the flock. A few milch asses and goats are here and there kept for the benefit of infants or invalids; but with these exceptions the cow is the only animal now used for dairy purposes.

No branch of agriculture underwent greater changes during the closing quarter of the 19th century than dairy-farming; within the period named, indeed, the dairying industry may be said to have been revolutionized. The two great factors in this modification were the introduction about the year 1880 of the centrifugal cream-separator, whereby the old slow system of raising cream in pans was dispensed with, and the invention some ten years later of a quick and easy method of ascertaining the fat content of samples of milk without having to resort to the tedious processes of chemical analysis. About the year 1875 the agriculturists of the United Kingdom, influenced by various economic causes, began to turn their thoughts more intently in the direction of dairy-farming, and to the increased production of milk and cream, butter and cheese. On the 24th of October 1876 was held the first London dairy show, under the auspices of a committee of agriculturists, and it has been followed by a similar show in every subsequent year. The official report of the pioneer show stated that “there was a much larger attendance and a greater amount of enthusiasm in the movement than even the most sanguine of its promoters anticipated.” On the day named Professor J. Prince Sheldon read at the show a paper on the dairying industry, and proposed the formation of a society to be called the British Dairy Farmers’ Association. This was unanimously agreed to, and thus was founded an organization which has since been closely identified with the development of the dairying industry of the United Kingdom. In its earlier publications the Association was wont to reproduce from Household Words the following tribute to the cow:—

“If civilized people were ever to lapse into the worship of animals, the Cow would certainly be their chief goddess. What a fountain of blessings is the Cow! She is the mother of beef, the source of butter, the original cause of cheese, to say nothing of shoe-horns, hair-combs and upper leather. A gentle, amiable, ever-yielding creature, who has no joy in her family affairs which she does not share with man. We rob her of her children that we may rob her of her milk, and we only care for her when the robbing may be perpetrated.”

The association has, directly or indirectly, brought about many valuable reforms and improvements in dairying. Its London shows have provided, year after year, a variety of object-lessons in cheese, in butter and in dairy equipment. In order to demonstrate to producers what is the ideal to aim at, there is nothing more effective than a competitive exhibition of products, and the approach to uniform excellence of character in cheese and butter of whatever kinds is most obvious to those who remember what these products were like at the first two or three dairy shows. Simultaneously there has been a no less marked advance in the mechanical aids to dairying, including, in particular, the centrifugal cream-separator, the crude germ of which was first brought before the public at the international dairy show held at Hamburg in the spring of 1877. The association in good time set the example, now beneficially followed in many parts of Great Britain, of providing means for technical instruction in the making of cheese and butter, by the establishment of a dairy school in the Vale of Aylesbury, subsequently removing it to new and excellent premises at Reading, where it is known as the British Dairy Institute. The initiation of butter-making contests at the annual dairy shows stimulated the competitive instinct of dairy workers, and afforded the public useful object-lessons; in more recent years milking competitions have been added. Milking trials and butter tests of cows conducted at the dairy shows have afforded results of much practical value. Many of the larger agricultural societies have found it expedient to include in their annual shows a working dairy, wherein butter-making contests are held and public demonstrations are given.

What are regarded as the dairy breeds of cattle is illustrated by the prize schedule of the annual London dairy show, in which sections are provided for cows and heifers of the Shorthorn, Jersey, Guernsey, Red Polled, Ayrshire, Kerry and Dexter breeds (see Cattle). A miscellaneous class is also provided, the entries in which are mostly cross-breds. There are likewise classes for Shorthorn bulls, Jersey bulls, and bulls of any other pure breed, but it is stipulated that all bulls must be of proved descent from dams that have won prizes in the milking trials or butter tests of the British Dairy Farmers’ Association or other high-class agricultural society. The importance of securing dairy characters in the sire is thus recognized, and it is notified that, as the object of the bull classes is to encourage the breeding of bulls for dairy purposes, the prizes are to be given solely to animals exhibited in good stock-getting condition.

Milk and Butter Tests

The award of prizes in connexion with milking trials cannot be determined simply by the quantity of milk yielded in a given period, say twenty-four hours. Other matters must obviously be taken into consideration, such as the quality of the milk and the time that has elapsed since the birth of the last calf. With regard to the former point, for example, it is quite possible for one cow to give more milk than another, but for the milk of the second cow to include the larger quantity of butter-fat. The awards are therefore determined by the total number of points obtained according to the following scheme:—

One point for every ten days since calving (deducting the first forty days), with a maximum of fourteen points.
One point for every pound of milk, taking the average of two days’ yield.
Twenty points for every pound of butter-fat produced.
Four points for every pound of “solids other than fat.”
Deductions.—Ten points each time the fat is below 3%.
  Ten points each time the solids other than fat fall below 8.5%.

This method of award is at present the best that can be devised, but it is possible that, as experience accumulates, some rearrangement of the points may be found to be desirable. Omitting many of the details, Table I. shows some of the results in the case of Shorthorn and Jersey prize cows. The days “in milk” denote in each case the number of days that have elapsed since calving; and if the one day’s yield of milk is desired in gallons, it can be obtained approximately[1] by dividing the weight in

  1. A gallon of milk weighs 10.3 ℔, so that very little error is involved in converting pounds to gallons by dividing the number of pounds by 10.
