US pig herd shrinks for first time in six years

After six consecutive years of growth, the US pig herd contracted slightly in December, according to the latest figures from the USDA. As at 1 December, the national herd was 77.5 million head, down 1% from the same point last year.


The decline in numbers was recorded in breeding animals and all but the heaviest slaughter pigs. AHDB lead analyst Duncan Wyatt suggested that this profile may be a hangover from COVID-19 disruption, leading to pigs staying on farms for longer.


The number of breeding sows, at 6.28 million head, was down 3% from last year, and down 1% from the previous quarter. The September-November 2020 pig crop was down 1% from 2019 at 35 million head. Sows farrowing during this period totalled 3.16 million head, down 1% from 2019. The average number of pigs saved per litter was 11.05 for the September-November period, compared to 11.09 last year.


Mr Wyatt also pointed out that this herd contraction may not be long-lived, as producers intend to have 3.12 million sows farrow from December to February 2021, 2% more than actually farrowed during the same period a year ago. However, intended farrowings for March-May 2021 are down 1% from the same period in 2020.
