Herd Production Recording
1.1 Persons testing must be members of the NZDGBA.
1.2 Members may form a group consisting of two or more members, one of whom shall be nominated Group Supervisor.
1.3 Members may test with a witness in which case they should forward to the Production Recording Officer the name and relevant details of the proposed witness.
1.4 Members may test without a witness. Unwitnessed tests may be subject to additional check tests as directed by the NZDGBA.
1.5 Members may test monthly or bi-monthly or 6 weekly. The minimum required for recognition by the Association of milk awards shall be bi-monthly.
1.6 Members shall supply to the PR Officer at the time of application the approximate number of tests and the proposed dates of all tests (e.g. 15th of each month).
1.7 Members shall supply to the PR Officer at the time of application a description of the measuring equipment to be used and whether the measurement is to be by weight or volume, together with a certificate of accuracy of the equipment, dated within 12 months prior to commencement of testing. Volume measurement is acceptable only with approved milk metres.
2 DUTIES OF THE GROUP SUPERVISOR/WITNESS
2.1 Be responsible for all group correspondence to the NZDGBA.
2.2 Ensure that all goats in the member’s herd be submitted for testing at the same time each milking.
2.3 Decide the roster, if applicable, within the group to witness each member’s test.
2.4 Ensure that the correct test sample is identified to the correct goat.
2.5 Ensure that all return sheets are filled out correctly and returned to the PR Officer no later than 14 days after the test date.
2.6 Ensure that the PR Officer is advised of the last test of the season for each member.
3. IDENTIFICATION AND RECORDS
3.1 Testing options approved by the NZDGBA are:
(1) All goats being milked as one herd through a shed must be tested, or
(2) All those does registered or recorded with the NZDGBA must be tested, or
(3) All does of the one breed, the minimum being Herd Register and Associated Record to Appendix D and Crossbred Y, must be tested, or
(4) Junior does (age 2 and 3 years) and/or senior does (age 4 years and over) with 1 year old does being optional.
(5) All does with the same sire, all registered or recorded with NZDGBA or
(6) Any doe or does registered or recorded with the NZDGBA
3.2 All goats on test must be readily identifiable by tattoo or microchip.
3.3 All forms supplied by the NZDGBA for use in Herd Production Recording must be filled out in full and in a legible manner.
4. MILK RECORDING
4.1 The frequency of testing shall be as nearly as possible to every 30 days in the case of monthly testing, or 42 days in the case of 6 weekly or 60 days in the case of bi-monthly testing.
4.2. A test shall comprise not more than two milkings during a 24 hour period.
4.3 The member shall ensure that the feeding and/or management practices immediately prior to and on the day of the test are not varied from the normal practices used at other times.
4.4 The member or group shall use either goat milk metres or weighing scales approved by the NZDGBA for measuring milk production.
4.5 Production figures will be based on milk yield only, unless approved butterfat percentages are supplied.
4.6 To obtain butterfat percentages, samples should be taken at each milking on the test date and a composite sample of 30ml (15ml from each milking on twice a day milking or 30ml from once a day milking) sent suitably identified to a recognised testing laboratory for testing at the member’s expense. These test results should be forwarded to the PR Officer on the laboratory’s official stationery, along with the test day return showing the milk weights/volume.
5. CALCULATION OF MILK PRODUCTION
5.1 The estimated milk production of a goat shall be calculated from and including the fourth day after kidding. If the kidding date is not available for any goat the calculation shall be made as if she had kidded seven days before the date of her first test in that lactation. For goats lactating prior to kidding, test day records shall be included in that total lactation yield.
5.2 Test day records shall be used to calculate the estimated yield on each goat, provided that in no case shall any one test day record be used to calculate the estimated yield more than 60 days either side of the test date.
5.3 The end of the lactation shall be taken as fifteen days after the date of the latest test in the lactation.
5.4 When a goat’s estimated lactation yield exceeds 305 days in length, it shall be shown in two sections, firstly that portion up to the 305th day and separately that portion in excess of the 305th day.
5.5 The estimated lactation yield of a goat bought in milk from another officially tested herd shall be continued in accordance with these Regulations provided that the PR Officer is informed of the addition and all the necessary details are supplied.
5.6 Test day figures will be calculated to the nearest 10 grams (0.01kg) or 10 millilitres (0.1 litres). Total for the test period shall be rounded to the nearest whole number.
5.7 The conversion factor for kilograms to litres shall be kg divided by 1.032 and rounded to two decimal places.
EXAMPLE OF CALCULATION
Date of test one = 30/09/96, pm 2.22 litres, am 2.45 litres
Total test day production = 4.67 litres
1. Back to kidding date less 3 days (see 5.1) = 16 days x 4.67 = 74.72
2. Forward 15 days = 15 x 4.67 = 70.05
Total for 31 days = 74.72 + 70.05 = 144.77 litres (rounded to 145 litres).
Date of test two = 28/10/96, pm 2.63 litres, am 2.77 litres
Total test day production = 5.40 litres.
1. Days from last test to this test = 28
2. Divide in half = 14 days
No of days taken on from last test = 15 days
3. Half days equal 14 and 15 days were taken on, so minus 1 day at last test amount = 4.67 once from total of 145 litres.
4. Take the other half number of days (14) and multiply it by this test = 14 x 5.40 litres =- 75.60
5. 15 days forward from this test = 15 x 5.40 litres = 81 litres.
Total for 59 days = 145 - 4.67 + 75.60 + 81.00 = 296.93 litres (rounded to 297 litres).
6. ABNORMAL CONDITIONS
6.1 The test day records of a goat shall be classified as abnormal if:
(a) the evening milk volume is greater than the morning volume by more than 25% and the daily milk volume is also more than 4 litres OR
(b) the goat is recorded as sick, injured or “in season” at the request of the member OR
(c) the sample is spilt.
6.2 Where the test day records are not used under the above Policy, the yield shall be assessed so that the goat’s production for that test is the same as the average of the preceding and following normal test day.
6.3 Where goats are recorded as sick etc., and had production assessed for two successive months, these goats may be regarded as dry from then on and/or delete any assessed production back to the last normal test.
7. CHECK TESTING
7.1 The NZDGBA Council shall have the right to make a surprise check test on any herd or on any goat at any time during the season.
7.2 The check test figures may be used in the place of the test day records.
7.3 Check tests will be supervised by two members selected by Council.
8. RECOGNITION FOR MERIT AWARDS
8.1 Members complying with the Policies as laid down by the NZDGBA Council will have recognition for milk merit awards as per NZDGBA Regulation 24 without the recognition for butterfat, unless approved butterfat percentages are supplied (see HPR Policy 4.6)
9.1 The cost per animal on Herd Production Recording will be set by the Council of the NZDGBA and advertised in the Association’s official publication.
9.2 The herd fee covers the period 1 August to 31 July each year.
10. PUBLICATION OF RESULTS
10.1 In undertaking to herd test with the NZDGBA Herd Production Recording scheme, members agree to the publication of their herd test figures by the NZDGBA.
10.2 When production records are published either orally or in writing, they shall be published in the same manner as set out in the Test Day or Annual Testing Returns provided to the member. The system of test, testing option and total number of animals being milked shall be stated, and all figures will be in the metric format.
11. INTERPRETATION OF THE POLICIES AND PROCEDURES AND GENERAL
11.1 In cases where the NZDGBA Council may doubt the accuracy of the records because information received is considered unsatisfactory (including information received from the group member), the NZDGBA Council shall have the right to make the herd records or an individual animal’s records unofficial.
11.2 In the event of any question arising as to the administration, operation or interpretation of the policies and procedures, the NZDGBA Council shall consider the matter and its decision shall be final.
