Importance of acute death syndrome in mortalities in broiler chicken flocks.
A survey of the weekly causes of mortality was carried out in a flock of 64,000 broiler chickens in Western Australia. Some 6.86% of the flock died or was culled in the period from day-old to slaughter and were examined post mortem. The most important cause of death, acute death syndrome (ADS) (36%), occurred during all weeks of production and 74% of affected birds were male. A comparison of liver biotin content made between 120 ADS-affected birds and 60 clinically normal flockmates established that the bottom status of ADS-affected birds was adequate.
