Har alla djur samma förutsättningar till god välfärd? : En jämförande studie mellan slaktkycklingars och slaktgrisars välfärd under transport till slakteri.

Sammanfattning: Every year 107 million broilers and 2,6 million pigs are transported for slaughters in Sweden. During transport, the animals can be exposed to adverse climatic conditions, congestion, fatigue, hunger, aggression and shock which can cause thermal discomfort, breathing difficulty and pain. The transport procedure can also affect the animals psychologically, such as social disorders, when they are socially separated from their herd, mixed with unknown animals, fear, novel environments and different managements. These stressors can lead to injury, death and detrimental welfare. In a comparison between pigs and broilers the extent of injuries and mortality differs during transport to slaughter. Pig mortality during transport must be reported to the county administrative board, but for broiler mortality, it only needs to be reported to the county administrative board when 1 % or more of the transported broilers have died during transport. This thesis is a qualitative literature study based on scientific articles and books. Injunctions and information by employees of the County Administrative Board has been used to quantify injuries and mortality of pigs and broilers during transport. None of Sweden´s 21 county administrative boards had kept any statistics on either injuries or mortality for animals during transport. There seems to be a higher tolerance for injured and dead broilers during transport compared to pigs, even though the individual suffering is the same regardless of size or number of injured animals.
