TESTING OF PUREBRED DAIRY COWS.

REVIEW OF THE NEW ZEALAND CERTIFICATE-OF-RECORD SYSTEM IN 1927.

W. M. Singleton,

Director of the Dairy Division, Wellington

The summary of results under the C.O.R. system for the calendar year 1927 shows that 529 certificates were issued during the twelvemonth. In comparison with the preceding year this represents a ■decrease of forty-seven certificates. It is noticed, however, that in the majority of classes the average production has increased, which .fact admits of two interpretations—either the quality of our purebred •dairy stock is improving, or breeders are more carefully selecting their test, teams. Probably there is something to be said on either side. A review of the production of C.O.R. cows since the commencement ■of the system indicates that much progress in average yield has been made, but of later years conditions have led to curtailed and more carefully chosen C.O.R. entries. THE OFFICIAL HERD-TEST AND C.O.R. The Official Herd - test, introduced last spring, is meeting with ■encouraging support. This test is open to all breeders entering cows for certificate-of-record test, and all registered purebred dairy cows are eligible. The system is also open to cows other than purebreds in those districts where no other means of having the cows tested (Group, Association, &c.) is conveniently available. Particulars of the “ 0.H.T.” were published in the Journal for July, 1927, but for the benefit of those who are not informed as to the system it may be briefly outlined .as follows : The Official Herd-test is carried out by C.O.R. testing ■officers at the time of their usual monthly visits. The testing officer takes a note of the milk-yield of O.H.T. cows for the same period as for C.O.R. cows. He also takes samples for two milkings. The owner takes no milk-weights, and from the testing officer’s figures for milk yield and test the returns for the month are figured in the head office of the Dairy Division. The O.H.T. is for a maximum period of 305 -daysthat is, a ten-months testas compared with the full-year test under the C.O.R. system.

During the height of the present season there were 214 breeders testing 605 cows under the C.O.R. system. Of these, m breeders were testing 1,506 cows under the O.H.T. system. This must' be regarded as gratifying support, and it is also pleasing to find that, although the O.H.T. was looked upon as more or less an experiment, no criticism of any importance has so far been levelled against it. Further, although the first year’s rules may require a little extension, it is not anticipated that they will need more than minor amendment. It may also be mentioned that the number of C.O.R. cows per breeder has not decreased as the result of the introduction of the Official Herdtest. A complete survey of the O.H.T. system in 1927-28 will be published in the Journal at the termination of the season.

CERTIFICATES ISSUED.

Since the commencement of the C.O.R. system 5,777 cows havebeen granted first-class certificates. During the year 1927, certificateswere issued on first performance for 449 cows, and on second or subsequent performance for 80 cows, making a total of 529 certificates. Details are given in the following table, figures for the preceding year being also given for purposes of comparison :

Second-class Certificates. — Only twenty-two second-class certificates were issued in 1927. These went to twelve Jerseys, nine Friesians, and one Red Poll. These numbers are obviously too small to permit of division into classes, but, grouping the cows of each particular breed into one class, the twelve Jersey records average. 523-91 lb. butterfat, and the nine Friesians 523-32 lb., while the one Red Poll yielded 347-07 lb. . '

Readers will recall that the rules governing C.O R. testing provide that for .first - class certificates the period between calving for commencement of test and calving subsequent to test shall not exceed 455, days (fifteen months). For second-class certificates an extension to--485 days (sixteen’ months) is permitted. The average period between, calving for test and calving subsequent to test for all cows which, gained first-class certificates in, 1927 was 393 days For second-class-C.O.R. the period was 468 days. .This compares with 391 days and. 470 days respectively. for the preceding, twelve months. JERSEYS. ' , . . Class-leaders. The list of Jersey class -leaders shows two changes for the year under review. These occurred in the junior two-year-old and the four-year-old classes. • In the former class Mr. G. E.- Yelchich’s Keston Flower, 694-28 lb. butterfat, gives way to Ivondale Oxford Lass, which, gained a certificate for. 731-29 lb. Ivondale Oxford Lass was -owned during her testing-period by Mr. R. S. Tuck, of Waharoa, although shewas bred by Mr. P. J. Peterson, -of Brixton, Taranaki., In the four-year-olds Mr. A. J. Smith’s St. Lambert’s-Bell, 780-32 lb. butterfat, isreplaced by Mr. G. E. Yelchich’s Keston- Flower, which raises the highest performance of this class to • 814-95 lb. Thus Keston- Flower,.

although defeated in one class, still holds a place in the list of classleaders. She was bred by Mr. C. B. Herrold, of Waiuku, while her certificates were gained under the ownership of Mr. G. E. Yelchich, of the same centre. The Jersey class-leaders are now as follows :

Jersey Class-averages.

. Three of the Jersey classes show an increase in average production for 1927 as compared with 1926, while in the two remaining classes there is a slight decrease. Taken as a whole the average Jersey for 1927, with 469-36 lb. butterfat, produced 7-68 lb. butterfat more than the average Jersey for the preceding year. A total of 383 cows is represented for 1927, and, as is usual, the largest classes are the junior two-year-old and the mature ; in fact, the junior two-year-olds, 167 in number, represent 43J per cent, of the Jerseys certificated during the year. The length of average lactation days three days in excess of that for the preceding year.

■ The class averages for 1927 and 1926 are given in the following table

The averages, class by class, of all certificates issued to Jersey cows since the commencement of the C.O.R. system in 1912 are given in the following table :

Jersey C.O.R. Bulls.

For the benefit of readers who are not conversant with' the details of the C.O.R. system, it may be repeated that a bull is entitled to be called a certificate-of-record bull when he has sired four certificate-of-record daughters, each daughter being from a different dam. In addition, the Jersey Breeders’ Association recognizes a special class for what it terms champion butterfat bulls. The qualifications for a champion butterfat bull require that the animal must have at least five C.O.R. daughters from different dams, each daughter having doubled its minimum butterfat requirement for a certificate. Some 266 Jersey bulls have now qualified for the C.O.R. list, while twelve of these are eligible for inclusion in the champion class. In the following list champion butterfat bulls are marked t. ,The list includes those C.O.R. bulls which have added to their number of C.O.R. daughters during the year, or have during that period newly qualified for the class.

FRIESIANS.

Class-leaders.

While 1927 added several meritorious performances to the steadily increasing list of our C.O.R. Friesians, the class - leaders for the breed remain as they stood four years ago. Except in the three-year-olds, however, the Friesian class-leadership yields are higher than for any of the other breeds tested under the C.O.R. system ; moreover, it is not likely that any of the present Friesian leaders will be seriously challenged during the season now in progress. The list of class-leaders is here repeated. , ■ • 1 : '

Friesian Class-averages. The average C O.R. Friesian for 1927 produced 502-09 lb. of butterfat, compared with 483-10 lb. for the preceding year, an increase of 18-99 lb. Of the seven classes into which the breed is subdivided four have shown increases, while the remaining three have failed to maintain the production of the previous twelve months. In all, 89 Friesians were certificated in 1927, a .falling-off' of 21 from 1926. The classaverages for 1927 and 1926 are given in the following table -

The following table shows the averages, class by class, of all certificates issued to Friesian cows since the commencement of the C.O.R system in 1912 :

Friesian C.O.R Bulls. Ninety-two Friesian bulls have now qualified for the C.O.R. class, and of these thirteen are eligible for inclusion in the present summary —that is, thirteen Friesian bulls have added to their number of C.O.R. daughters during the year, or have during that period newly qualified for the class. Four new names were added during the year. The list is given in Table 9 which follows. (

MILKING SHORTHORNS. Class-leaders. . ' With the exception of the junior four-year-old class, the Milking Shorthorns experienced no change of class-leadership during 1927. It may be mentioned, however, that the record of Mr. A. J. Melville’s 'Glenthorpe Lady, whose yield of 856-85 lb. butterfat places her at the head •of the mature class, was . closely challenged by Hon. Mrs. E. J. Blyth’s Braeside 1 Sweet Nell 2nd with the excellent performance of 851-21 lb. The new leader of the junior four-year-olds, Matangi Matilda 4th, was -also owned and tested by Mrs. Bly th, although bred by Messrs. Ranstead Bros. Matangi Matilda 4th’s record is 630-38 lb. butterfat, which exceeds the yield of the previous leader, Matangi Nancy 2nd, by ■approximately 22 lb. . The class-leaders now stand as follows :

Milking Shorthorn Class-averages.

Twenty-eight first-class certificates were issued to Milking Shorthorns in 1927,. compared with twelve for the preceding year The average yield of the twenty-eight cows certificated last year was, 445-82 lb. butterfat, as against 508-89 lb. for 1926. Needless to say, however, the influence of individual records defeats satisfactory comparison on a class basis, while the matter, of production for age is an important factor when grouping together, irrespective of age, such small numbers of records. The class-averages for this breed for the past two years are as follows :

The following table shows the average, class by class, of all certificates issued to Milking Shorthorn cows since the commencement of C.O.R. testing for this breed in 1914 :

Milking Shorthorn C.O.R. Bulls.

One bull, Dominion Glaxo of Ruakura, was added to the Milking Shorthorn list during the year, which now totals six. Of the bulls previously qualified only one, Matangi Pride, added to his C.O.R. daughters during the year. The figures for these two bulls are now as follows : Dominion Glaxo of Ruakura, o —0 —5 ; Matangi Pride, io-—o —o —lo (see key at head of Jersey bull list). AYRSHIRES. Class-leaders. The period under review failed to bring any changes to the classleaderships of the Ayrshire breed. Although several good records were authenticated during the year, none of the existing championship performances was seriously challenged. The list, which remains as at the close of 1925, is reprinted, as follows :

Ayrshire Class-averages.

Although three of the four classes into which the Ayrshire breed is subdivided showed an increase in average yield for 1927 as compared with 1926, the average for the breed as a whole has decreased from 440-31 lb. butterfat for 1926 to 411-42 lb. for 1927. The explanation of the decrease is to be found in a study of the mature class for the two years. Out of sixteen Ayrshires certificated in 1926, ten were in the mature class, which that year was a particularly strong class, the ten representatives averaging 504-01 lb. butterfat. On the other hand, only three cows were in the two-year-olds, the lowest-yielding class. In the year under review seventeen Ayrshire cows received first-class certificates, but only five of these were in the mature class, whereas seven were among the two-year-olds. Moreover, the mature class in 1927 was weaker in quality as well as numerically, the average yield of the five cows being 472-78 lb. butterfat, as compared with an average of 504-01 lb. for the ten in 1926. The decrease is therefore not so

serious a falling-off as might at first appear. The Ayrshire classaverages for 1927, together with those for the preceding year, are as follows :-

The following table shows the averages, class by class, of all certificates issued to Ayrshire cows since the commencement of C.O.R. testing in 1912 :

Ayrshire- C.O.R. Bulls. r Only one name is to be added to the Ayrshire C.O.R. bulls ,as the result of the year’s testing, making a total of seven to date. The new C.O.R. bull is Allandale White Hope, his figures being 50 —0 — (see key at head of. Jersey bull list).

RED POLLS.

Class-leaders.

One change has taken place in the Red Poll class-leaderships, this occurring in the . four-year-old class. Mr. B. W. ’ Harvey’s Susie Ann, with 448-48 lb. butterfat, ■ yields place to Wayward 6th B No. 1, owned by Mr. G. S. Young, of West Plains, her record being 580-05 lb. This cow already holds the leadership of the two-year-old cla .s with a certificate for 511-42 lb. butterfat. Moreover, both her records are higher than any other for the breed. The full list is comprised in Table 16.

Red, Poll Class-averages.

Twelve Red Polls gained certificates last year, an increase of two over 1926. All four classes were represented, although there was only one cow in the three-year-olds. This being so, comparison with the previous year's results is impracticable. The twelve Red Polls certificated last year averaged 372-23 lb. butterfat. Details are given in the following table :-

The following table shows the averages, class by class, of all certificates issued to Red Poll cows since the commencement of C.O.R. testing for this breed in 1918 :

. Red Poll C.O.R. Bulls. No new 1 Red Poll bulls have been added to the list for this breed during the year, and none of the bulls previously qualified has added to his number of C.O.R. daughters. The three Red Poll C.O.R. bulls are Aviator, Belligerent,, and Force Majeure. We again extend our thanks to the secretaries of those breeders’ associations who co-operate with the Dairy Division in the carrying out of the C.O.R. testing, and who each year render us much valuable assistance-‘Messrs. W. M. Tapp (Jersey), J. P. Kalaugher (Friesian), A. W. Green (Milking Shorthorn), R. H. Spencer (Ayrshire), and L. T. Wild (Red Poll).

CLOSING RECORDS FOR 1927.

Only one of the several outstanding records for the year 1927 has been completed since publication of the last C.O.R. list in the March Journal. The particulars of this record are as follows: Ayrshire

mature class —Bonnie Girl of Riki, tested by Atkins Bros., Manakau ; age at start of test, 7 years 186 days ; yield, 10,613-7 lb. milk, 424-66 lb. butterfat, in 263 days.

The fact that a certain number of owners have neglected to advise dates of calving subsequent to test, or to return necessary declarations for cows already qualified, signifies, of course, that the foregoing summary of C.O.R. testing in 1927 is not absolutely complete. The summary of results, however, is already overdue, and it was thought inadvisable to defer its publication any longer.

* Representing 528 cows, one cow having qualified for two certificates within the year.

* No additional cows for 1927.

* No three-year-olds under.test in 1926.
