British milk deliveries fall four percent in October

Great Britain's milk deliveries fell by four percent in October 2026 compared with the same month last year, according to figures published by the Agriculture and Horticulture Development Board (AHDB).

Total deliveries reached 1,053.24 million litres during the month, equivalent to an average of 33.97 million litres per day. Production remained approximately one percent above the five-year average despite the annual decline.

The latest figures, published on 10 November, extend several months of reduced milk production as dairy producers face tighter margins, lower forage availability, and continued pressure on herd numbers.

Daily deliveries varied between 33.21 million litres and 34.42 million litres during October. The seven-day rolling average remained below the corresponding 2025 production level, reflecting the reduction in output relative to the previous milk year.

Between 1 April and 31 October, British milk deliveries totalled 7,450.18 million litres. The cumulative figures demonstrate how lower production over successive months has affected the amount of raw milk entering the market.

AHDB's latest production forecast anticipates a 2.2% decline across the full 2026–27 milk year, equivalent to approximately 284 million fewer litres than the preceding season.

The forecast puts annual production at around 12.74 billion litres. It also anticipates a slower rate of contraction of approximately 1.1% during the first half of the 2027–28 milk year.

Lower farmgate milk prices have combined with increasing production costs to place pressure on dairy margins. The effect differs between producers according to their contractual arrangements, feeding systems, and exposure to purchased inputs.

Energy, fuel, fertiliser, forage, straw, and labour costs have all contributed to operating pressures. Disruption to international feed supply chains has added uncertainty to purchasing arrangements, while domestic weather conditions have affected the availability of conserved forage.

Strong grass growth earlier in 2026 supported the initial production of silage on some farms. Prolonged dry conditions during the summer subsequently reduced forage growth and limited the amount of material available for later harvesting.

A relatively dry autumn allowed some farmers to continue producing forage into October and November, although AHDB warned that the quality of these later cuts could be lower than those obtained under more favourable conditions.

Forage quantity and nutritional quality influence the amount of supplementary feed required to maintain milk production. Producers may need to adjust rations or purchase additional material where conserved feed does not provide the desired nutritional composition.

Those adjustments can increase the cost of production, particularly when feed markets and other agricultural inputs remain expensive.

The effect on individual dairy farms depends partly on the type of feeding system. Businesses relying heavily on grazing face different seasonal conditions from those using greater quantities of conserved forage and purchased feed.

Milk supply contracts introduce further variation. Some producers operate under agreements that take account of changes in production costs, while others are exposed more directly to movements in dairy commodity markets.

AHDB has identified contrasting commercial positions between farms supplying retail-aligned liquid milk contracts and those supplying milk for products such as cheese.

These differences mean that falling national production cannot be attributed to one uniform financial condition across every dairy business. Price movements, operating costs, and the contractual treatment of those costs all influence the decisions made by producers.

Lower milk deliveries can also affect dairy processors differently depending on the products manufactured and the sourcing arrangements used to obtain raw milk.

Liquid milk plants require reliable intake volumes to support regular packaging and distribution schedules. Cheese, butter, milk powder, and ingredients manufacturing have different production requirements and may respond differently to changes in available milk.

Processing yield is influenced by milk composition as well as volume. Fat and protein content are particularly important in operations manufacturing cheese, butter, and dairy ingredients, meaning the quantity delivered does not alone determine finished-product output.

Manufacturers may therefore experience changes in the relationship between raw-milk intake and production yield even where the physical volume of milk changes only modestly.

The AHDB figures measure milk delivered by producers, not the finished production of individual dairy processing companies. They cannot establish that a four-percent decline in raw-milk deliveries has produced an equivalent reduction in every manufacturing category.

Milk collection geography also influences how processors experience supply changes. Regional drought conditions and variations in producer contracts may affect the quantities available through particular collection networks.

Herd numbers represent a longer-term constraint on recovery. AHDB's October market outlook estimated that the British milking herd had fallen to approximately 1.57 million head by July 2026, a 2.2% reduction compared with the previous year.

The decline affected most age groups, while the number of young female animals entering the herd also fell. Lower replacement numbers can restrict future production capacity even if feed conditions and milk prices subsequently improve.

Strong beef prices provide an additional commercial influence because they affect the value of animals leaving dairy herds. Producers must weigh those returns against the potential contribution of animals retained for milk production.

Bluetongue disease remains another concern. The disease has affected livestock holdings across Great Britain, and AHDB identifies its potential consequences for fertility and milk yield as part of the wider production outlook.

Vaccination has been reported on many dairy farms, although uptake is not universal. The effect on production will depend on the extent of disease exposure and the circumstances of individual herds.

Seasonal production patterns also remain relevant when interpreting the October figures. British milk output normally rises during the spring flush and changes throughout the year according to calving patterns, feeding arrangements, and weather.

The October reduction is therefore measured against the equivalent month in 2025 rather than representing a sudden four-percent fall between September and October.

Production remaining slightly above the five-year average also places the decline in context. It indicates that current volumes are lower than the comparatively strong output recorded last year without necessarily falling below longer-term historical levels.

AHDB expects the combination of tighter margins, lower forage stocks, declining herd numbers, and animal health risks to continue constraining supply through the remainder of the milk year.

Subsequent delivery figures will establish whether production follows the forecast trajectory and how much raw milk remains available for Britain's dairy manufacturing operations.
