New Zealand Dairy Statistics 2014-15

ii) Monthly averages
• Highest average production per cow per day occurred in October
The seasonal average figures presented in Table 4.5 are calculated using national monthly herd test averages, and are therefore affected by the
number of samples processed. Statistics for May, June, and July are based on far fewer cows than the statistics for the other months, as only a
few herds (generally winter milk herds) test in these months. Differences in climate between regions (which in turn can affect the mating
period), available feed, and cow condition are reflected in differing months of peak production.
All cows herd tested in each month were included, provided they were tested at least once during the season (Table 4.5). Average peak cow
production occurs between August and October, with regions in the mid to lower South Island peaking in October.
