Animals  suffering from bad conditions during transportation or from long distance  transports have caused consumer reactions all over the EU. But are the  reactions in accordance with increased transports over time? And what are the  economic incentives to animal transports? The aim of the report is to give an  answer to these questions, using the situation in Sweden as a general example.
One  conclusion from examining the animal transport patterns in Sweden is that  big slaughter houses seem to attract deliveries from distant and small-scale  breeders. Also, when there is a (small) slaughter house within the same area as  the breeder, the probability of a long distance transport is higher from small-scale  breeders. This result leads to one important economic incentive; economies of  scale. Economies of scale are markedly present in the slaughter industry; the  slaughter cost per unit decreases when there is an increase in production. To  take advantage of this, a slaughter house needs to increase the number of  delivered animals, and it thus also needs a larger reception area. This need  results in a longer transport distance unless there is an ongoing simultaneous  geographical concentration of breeders.
Statistical  analysis shows clear signs of concentration of the breeding in Sweden during  the investigated period (1990-1999). Also, using regression analysis, a  positive correlation between the total number of animals in a municipality and  the number of animals being slaughtered there was found. This suggests either  that breeding has been concentrated to municipalities with a big slaughter  capacity, or, reversely, that slaughter houses have been located where the  animals are. 
In the report, it was also investigated  how the structural changes have affected the average distance of transport for  the animals. The results of this analysis show that a larger part of the  animals were located closer to a slaughter house in 1999 compared to 1990. The  average transporting distance of animals to slaughter decreased during the  period. However, the findings also indicate that some animals actually have a  longer distance to travel. All in all, in Sweden, structural changes due to  economies of scale do not seem to have had any significant negative impact upon  the average animal transporting distance to slaughter.
