Utilization of mild extruded water-soaked leucaena leaves mixed with cassava (MEWLC) in growing (20-60 kg) and finishing (60-90 kg) pigs were studied using a total of 40 Large white pigs which consisted of an equal number of males (castrated) and females and were divided into 5 group of 8 animals each. Each group of animal was randomly fed one of the experimental diets which had protein of MEWLC substitued for protein of normal diet as following, 0, 20, 30, 40 and 50 percent both at growing (20-60 kg) and finishing (60-90 kg) periods. The animals were kept individually where feed and water are provided ad libitum. Average daily gain (ADG) and feed efficiency or feed conversion ratio (FCR) were decreased when in diets had high MEWLC significantly (P0.05). But utilization of MEWLC in finishing diets did not affect ADG and FCR of the finishing pigs but had slightly low quality when the high MEWLC was use.
