The trend in the percentage of total herds using herd testing shows an increase from the previous season (Graph 4.1).

Aside from East Coast where all 8 herds were herd-tested, Taranaki had the highest percentage of herds using herd testing (81%) followed by Nelson/Marlborough (78%). Taranaki also had the highest percentage of cows herd tested (82%). Central Plateau recorded the lowest percentage of cows herd tested (58%).

B. Herd test averages The lactation yield figures in this section are for herd-tested cows. Seasonal and breed averages (parts i and iii) are calculated on lactation yields for herds tested four or more times during the season. Monthly averages (part ii) are calculated on lactation yields for herds tested at least once during the season, and only cows that lactated for 100 days or more were included in the herd test averages. These figures are different to the average milksolids figures given in Chapters 2 and 3 (national and regional dairy statistics, respectively), which were based on all herds supplying a dairy company (regardless of whether herd testing was used) and represented the average production per cow as supplied to the dairy company. Days-in-milk (herd testing) information is the number of days from the start of lactation to the calculated end of lactation. The start of lactation is four days from calving (with a maximum of 60 days between the estimated start of lactation and the first herd test). The end of lactation is the last herd test date plus 15 days. The inclusion of herds with fewer than four tests reduces the calculated average lactation length: therefore, the number of days-in-milk, calculated using this method, does not necessarily reflect the average lactation length of dairy cows. The days-in-milk (production) figure is the number of days from the estimated start of lactation to the estimated end of lactation (reported since 1997/98). The results are derived from seasonal supplier tanker pick-up information, adjusted for calving spread. The days-in-milk (production) methodology provides a more accurate measure of the average lactation length of dairy cows than the herd-testing methodology. i) Seasonal averages • North Canterbury has the highest milkfat, protein and milksolids production (kg/cow) • West Coast has the highest protein and milksolids percentages The average per-cow statistics for each region are summarised in Table 4.3. North Canterbury recorded the highest per cow milk volume (5,077 litres), milkfat (230 kg), protein (197 kg) and milksolids (427 kg), of cows herd tested. Taranaki recorded the highest percentage for milkfat (5.08%) and West Coast the highest percentage for protein (4.03) and milksolids (9.09). Herds in South Canterbury recorded the lowest average somatic cells (156,000 cells/ml), while herds in East Coast and Hawkes Bay had the highest averages (294,000 and 229,000 cells/ml respectively).
