In December 2017, the Swedish Board of Agriculture conducted a survey of the number of pigs in Sweden. There were two purposes with this survey. Partly to get good estimates of adopted pigs in December 2017, but also to evaluate the model commonly used to estimate the number of pigs in December. Sweden is obligated to supply data on the number of pigs twice a year, in June and December, since the entry of the EU. The June results are based on the annual survey of livestock produced by the Swedish Board of Agriculture, while the December results are based on a model where the change between June and December is adjusted to the results of the June survey.

The result of this survey shows that the total number of pigs in December 2017 is 1.5 % higher than in June, which however is not statistically significant. Divided into different categories of pigs, only the number of piglets is higher in December than in June.

However, the number of companies is significantly lower in December than in June. Approximately, it is 15 % fewer companies with pigs in December 2017 than in June 2017. Looking only at the surveys done in June, the number of pigs companies has been relatively unchanged since 2013.

The significantly lower number of companies means that the average number of pigs per holding increases significantly between June and December. From an estimated 1 071 pigs to 1 278 pigs per holding.

The survey also shows that the model used to estimate the number of pigs in December does not really take into account all factors that are crucial and a more detailed work should be initiated to improve the model.
