  1. n is number of farmers answering the question
  2. The straw ration per pig was calculated from the farms straw consumption. Farms that were unable to provide such information was excluded from the calculations and hence the number of farms were reduced from 43 to 35 nursery units and 43–31 finishing pig units
  3. The straw ration and straw length was also calculated excluding farms with deep litter systems (removing 6 nursery units, 4 finishing pig units) since deep litter systems are uncommon in European pig production
