British pork supply shifts from carcass weight back to slaughter numbers

British pig-meat production continued to grow in the third quarter of 2026, but the driver changed. According to AHDB, pork output increased 2.8% year on year to 246,600 tonnes. The increase was smaller than in the first half, however, because carcass weights had returned almost to the previous year’s level.

Clean pig slaughter totalled 2.64 million head in the quarter, 2.3% more than a year earlier; the first nine months reached 7.92 million head, up 2.4%. Average carcass weight fell to 89.9 kg—2.1 kg below the second quarter and only 0.1 kg above the third quarter of 2025. Earlier in the year, pigs held longer because of processing bottlenecks had lifted weights markedly and, with them, production.

For buyers and processors, the data prevent an overly simple reading of availability. Tonnage alone does not describe the future raw-material flow. If growth rests more on slaughter numbers than on weight, supply composition changes and the additional contribution of heavier animals to particular cuts and trims diminishes.

Sow and boar slaughter also deserves attention: it reached 56,000 head, 15.4% above the previous year and the highest quarterly level since the fourth quarter of 2023. AHDB regards sustained higher culling as a possible early signal of breeding-herd reduction. This is not yet a firm shortage forecast, but it is an indicator that should be incorporated into contracts, cut planning and 2027 coverage.
