Product Type: Livestock – pork
Stage: Production & Harvesting
Problem: Pig death during transportation and handling due to the PSS gene included in swine herd
Solution: DNA stress test

1. The Halothane gene, referred to as the porcine stress syndrome gene, causes malignant hyperthermia, which can be triggered by stress or exposure to the anesthetic gas halothane. The effects of the gene have since the 1960s been closely associated with development of pale, soft, and exudative (PSE) meat.
    
2. So far, the DNA stress test is an excellent method to identify PSS gene type (AA, AB, BB) from different pig breeds and also help to achieve the target of free PSS gene in pigs. Performance of this program requires significant time, investment, and training. The acquisition of resources from the private of public sector is a key point along with knowledge sharing from more-experienced economies.
    
3. From 1996 onward, identifying PSS gene type (AA, AB, BB) in pigs and discard the gene from pigs and produce free PSS gene pigs have been important targets in Chinese Taipei. Boars free of PSS can be exhibited and traded in a breed animal market.
