Show DAIRY STOCK. At the recent convention of the American dairvmen's association Pro:essor U'etherell, of the Boston Lnlticator, made an address on breeding breed-ing Block: Upon -Jain- j.tork depends dairv .i'ilar.tlry. Dairy block is such, as all agree, us is bred and kept lor the production of m.Ik for the manufac-urc manufac-urc of butter and cheese, either or both. 1 hot breed of cows wnicb irom a given amount of feed will produce the largest mess of milk suitable for butter or cheese is the breed that dairymen desire. But what breed is thai? Soil, quality of cattle, breed and price are to be considered. Short horns, Holsteins and Swiss, among large breeds, and Devona. Ayrshires, Jerseys and Guernseys will be considered; consid-ered; also among trie natives, nondescripts, non-descripts, are some good cows. THE SELECTION OF BREEDS. If the dairymen have a farm suited to the keeping of large cattle, then one of the firat three breeds will be selected. The Short horns have been said to be the best. The history of , the Short horns shows that before their j breeding for beef, th-y were the finest j large blooded milkers. Of Holsteins, iGerret Smith Miller of Peterboro, reports re-ports an average yield per cow per hinnum of 9,507 pounds and upwards. : The speaker then gave facta and illus-Jtrahons illus-Jtrahons going to show that the Hoi-stems Hoi-stems are superior in quantity of milk ! to any other breed, while tho quality is as good ns the average ot diiry breeds. Ayrshires were triedin the I milking herds near Loudon and found wanting, not yielding as much milk I in proportion to the space they occupy oc-cupy as the Short horns. On good keep they tend to fat rather than milk. The sole ofiico of the Jersey cow is to produce the largest amount of rich and highly-colored cream from a given a.nouut of milk. Beauty of form, etc., are secondary matters. Careful experiments have shown that to make one pound of butter from the milk of Jerseys, six and one-third quarts of milk were necessary, while crossbreds required a much larger amount. Eleven quarts of the milk of natives were required. Thomas Motley of Jamaica plain, from his Jersey cow, Flora, iu 50 weeks made oil pounds of butter. The Guernsey is larger than the Jersey, muzzle broader, eye less prominent, nose a rich yellow or buff, tho eye banded with the same color, of larger, smoother and more rotund form, and remarkable for the golden color of the butter, even excelling that of the far-famed far-famed Jersey. CROSS BREEDING. Breeding from a bull and cow of similar type, the progeny will be like, but, of higher degree. A short-horned bull whose hereditary power is represented repre-sented at 100, and a cow at GO, the offspring would be reduced to 40. Wore the of .spring a bull, both sire and oflspring nmy appear equally perfect per-fect in form and general qualities, but the hereditary transmission is as much greater in the former sire as the ratio of 100 to 40; hence the former is much more valuable for breeding purposes. By breeding animals an-imals ol a similar type, the oflspring : will be likely to posses a greater power of hereditary transmission of his char-1 acteristics. Animals of opposite characters mutually weaken each, other's influence, and the oflspring I possess the power oflransmission iu a I reducid degree. |
