This book was released on 2018-02-05 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Outlines of the Advanced Registry System of the Holstein-Friesian Association of America: And Rules for Officially Authenticated Butter Fat Tests The first association of breeders of these cattle was formed in 1871, the first herd-book being published the following year. The present holstein-friesian Association was formed in 1885 by the union of two earlier associations, and is now the largest association of breeders of pure-bred dairy cattle in the world. Frederick L. Houghton, Brattleboro, Vt., has long been the able secretary of the association, and Wing R. Smith, Syracuse, N. Y., its trusted treasurer. Mr. S. Hoxie, the veteran superintendent of Advanced Registry, retired June 7, 1905, on account of age and ill health, at which time he was succeeded by the writer. How many holstein-friesian cattle there are now living is unknown; but since the juncture of the two old associations in 1885, to November 1, 1907, females and males have been recorded. The holstein-friesian Advanced Register, based for entry upon individual merit, was established in 1885; since which time eighteen volumes have been published and the nineteenth begun, containing entries of nearly cows and 533 bulls. The age of any female is computed as that at the time of last calving or aborting, and the require ments for entry vary with the age; being not less than pounds butter fat in seven consecutive days for a heifer calving at just two years of age or younger, and increasing proportionately to not less than 12 pounds butter fat for a cow calving at five years old, there being no increased requirements for increased age after a cow reaches the age of five years. Only bulls having four or more daughters which have been entered in the Advanced Register on official records of butter fat are accepted for entry. The rules for the entry of cows.in the holstein-friesian Advanced Register are very stringent, being designed to place every Holstein - Friesian record beyond even a shadow of a doubt. Every milking during the period of test must be watched, weighed, sampled and tested. By a representative of some State Agricultural College; and thus, because of resulting expense, the bulk of its records are for short periods, largely for one week. It will be readily admitted that eighteen pounds of butter fat will make twenty - one pounds of the best commercial butter, or an average of three pounds of butter per day when eighteen pounds of fat is produced in seven consecutive days, and that almost no cows other than holstein-friesian have ever, under strict rules, produced such an amount. The records of the holstein-friesian Advanced Register show that 324 cows have produced officially in excess. Of eighteen pounds butter fat in seven consecutive days; of which 122 cows have produced between eighteen and nineteen pounds, eighty-three cows between nineteen and twenty pounds, sixty-three cows between twenty and twenty-one pounds, twenty-three cows between twenty-one and twenty-two pounds, sixteen cows between twentytwo and twenty-three pounds, nine cows between twenty-three and twenty-four pounds, three cows between twenty-four and twenty-five pounds, three cows between twenty-five and twenty-six pounds, one cow between twenty-seven and twenty-eight pounds, and one cow over twenty-eight pounds. It must be remembered that while many of these records were made by cows much under five years of age, there were large numbers of records made by two and three year-old heifers which were, considering age, proportionately as large, yet fell short of the eighteen-pound minimum required for this list.

This book was released on 2017-11-25 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Measuring the Breeding Value of Dairy Sires by the Records of Their First Few Advanced Registry Daughters The breeding value of dairy sires lies mainly in their ability to transmit to their offspring factors for high milk and butterfat produc tion. The fact that all sires are not equal in this respect makes it necessary to select for breeding purposes only those sires transmitting the largest number of such factors. An expression of this transmitting ability may be found in part in the milk and butterfat productions of the daughters, and it is by means of these productions that breeders in general have measured the breeding value of dairy sires. This method of measuring breeding values, altho used extensively at the present time, is open to several objections. The productions of the daughters used in measuring the breeding value of dairy sires are those that are recorded in the advanced registers of the various purebred dairy cattle associations; daughters with records in these registers have fulfilled certain production requirements and are spoken of as tested daughters. The tested daughters of a sire, in most cases, represent only his best daughters, which are a small percentage of all his daughters. This selection is due in part to the requirements of'the advanced registers, but in the main to the fact that under the present system of advanced registry testing it is exceedingly unprofitable to test daughters other than those showing signs of high producing ability. The productions of only the tested daughters, there fore, do not provide an absolute basis upon which to measure the breeding value of the sires. However, since the tested daughters of all sires have been subjected to the same type of selection, their produc tions provide a uniform basis and may be used as a means of measure ment with the limitation that they will give only relative results.

Book excerpt: Excerpt from Better Cows From Better Sires: A Study of Cow-Testing Association Records of Dams and Their Daughters The proved purebred dairy sire seems to be the best solution of the dairy-breeding problem.

How such sires may be kept until the production records of the daughters become available is one of the unsolved problems of the dairy world to-day. Every dairyman is interested in its solution.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Studies in Milk Secretion, Vol. 17: Relation Between Milk Yields and Butter-Fat Percentages of the 7-Day and 365-Day Tests of Holstein-Friesian Advanced Registry Cattle During the course Of their development two of our leading dairy breeds, the Jersey and. The holstein-friesian, have made extensive use Of the 7-day test. The Jersey breed has now prac tically discontinued the use Of the 7-day record advocating the 365-day record as the only measure Of the cow's worth as a milk producer. The discussion of the merits of the Short time test and the long time test has recently entered a highly controversial stage even among its chief adherents, the holstein-friesian breeders. Few, if any, Of the supporters Of either camp have actively asserted that the long time test was not desirable. The contest has centered on the validity. Of the 7-day test as a meas ure Of the cow's subsequent performance. This question is intricate. It is really one phase of the larger question of the normal fluctuating variability of milk yield. In fact, it is from this angle that the authors were led into this problem, for whatever Significance may be attached to this variability, a fairly comprehensive knowledge of its magni tude forms a necessary prelude to the further use Of such data for genetic studies.

Book excerpt: Excerpt from California State Dairy Cow Competition, 1916-18 The record period decided upon for cows in the competition was ten months, which is the average normal lactation period of dairy cows. The reasons for adopting this period, instead of one for a full year, are stated in the circular cited above. Later developments in connection with advanced-registry tests of different breed associa tions have further emphasized the wisdom of a ten - menth record period. The production by the cows for each month was determined on the basis of tests of one or two days' duration (one day for grade or common cows, two days for pure-breds, in accordance with the rules of the various breed associations), and the milk records fur nished by the owners, which were checked up in various ways. The accumulated credits for ten consecutive months make the records of production of milk and butter fat for the cows in the competition.

Book excerpt: Excerpt from Studies in Milk Secretion, Vol. 14: The Effect of Age on the Milk Yields and Butter-Fat Percentages of Guernsey Advanced Registry Cattle The data shows that milk yield rises at an ever decreasing rate as the age of the cow increases until the age of maximum production is reached, years. From this age of maximum production the milk yield declines at an ever increasing rate as the age increases. The butter-fat percentage shows a slight but significant decline as the age of the cow advances. This decline on the average amounts to about three tenths of one per cent in the ten years from two to twelve years old. Tables are presented to enable the reader to determine the eight year milk yield or butter fat percentage of a cow of differ ent production at other ages, assuming the conditions under which the test is made, to he the same as those for the Advanced Registry test.
