DEFRA has revised its milk production figures upwards for each month it has previously reported on in 2017 (January to October). This means the cumulative production for the calendar year to October is now 12,315 million litres, an increase of 332 million litres (+2.7%) compared with the previously published data. Production for the current milk year, April to November, is now reported to be 9,860 million litres(2.8%) higher than previously reported.
AHDB Dairy has voiced concerns on a number of occasions over the figures, but state, despite the adjustments being significant, that the 2017 figures are now inline with its expectations. The levy board does however believe the May 2016 to December 2016 figures are about 20 million litres lower than expected, and therefore cautions using them in making year-on-year comparisons.
The revisions have apparently been made following ‘re-analysis of submitted data’, but it is a worry and begs the question whether there is a lack of detail/care being applied in gathering and analysing the data, or indeed whether the processes have not been updated to take into account the changing structures within the industry (perhaps due to funding cuts). Especially when we hear other statistics are seeing large revisions as well (see meat market article). The problem being that farmers and processors are making decisions based on these figures.
