摘要

The establishment of emission inventories presupposes animal populations that are homogeneous with respect to feeding and management. For weaners and fattening pigs, the official surveys for pigs do not meet these requirements. Hence, the official animal numbers have to be redistributed to serve this purpose. In this paper, the algorithms to derive the animal categories of the emission inventory (weaners, fattening pigs) from survey data (piglets below 20 kg, young pigs lighter than 50 kg, fatteningpigs 50 to 80 kg, fattening pigs 80 to 110 kg, fattening pigs heavier than 110 kg) are defined. Also, the calculation of the mean population of suckling-pigs needed for the redistribution of official animal numbers is described.The updated animal populations result in decreased overall emissions from pig husbandry in the German emission inventory.
