摘要：Soybean meal and grain corn are feedstuffs that normally used as the main ingredients in poultry feeds as a source of protein and energy in tropical countries. The availability of these feedstuffs for broiler nutrition nowadays is becoming more competitive. Thus, food security, especially in the developing countries, would be susceptible. Currently, efforts are being made to use alternative feedstuffs as a sustainable feed resources to substitute portion of soybean meal and grain corn in poultry diets due to their high price since both of the raw material were imported. In Malaysia, usage of PKC is common in ruminant diets, but limited in the non-ruminant diets especially in poultry diets due to the high fiber content of PKC. Several works have been conducted to increase the nutritional contents of PKC as one of the measures to reduce and/or eliminate the constraints of utilizing PKC in poultry diets. The method used to achieve this target is either through physical, chemical, biological or combination of these treatments. This paper discusses the use of PKC as the sustainable feed resources that can be incorporated in the poultry feeds. Hence, emphasis should be given to improve nutritional values of PKC in order to reduce feeding cost of poultry.
