UTILIZATION AND RESEARCH ON PORCINE BY-PR ODUCTS IN TAIWAN

Pig production amounts over 60% of the total quantity and value of the livestock production in Taiwan. So, the utilization of porcine by-pro ducts from slaughterhouses and meat-packing plants is the most urgent problem. The majority of porcine by-products, except for blood (which is made into blood cake or blood powder or discarded as waste), hides (used for leather tanning or discarded as waste) and lungs (used for f ish fodder or discarded as waste), are sold fresh and consumed by Taiw an's inhabitants. Research on porcine by-products is focused on promot ing the add-in value of porcine blood, hides and lungs.
