Abstract


The unavailability and high cost of traditional ingredients calls for more research into alternative sources for pig feeding in the South Pacific region. The effect of replacing feed protein with cassava leaf meal (CLM) protein in weaner and growing pigs’ diets was investigated in two experiments. In experiment 1, three diets in which CLM protein replaced 0, 15 and 30% of feed protein were fed each to five replicate pens of weaner pigs. Feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR) were improved and feed cost of gain reduced (P<0.05) on 30% while dressing percentage was maximized (P<0.05) on 15% protein replacement diets. In experiment 2, three diets containing 0, 30 and 45% CLM protein as replacement for feed protein were fed as in experiment 1 to grower pigs. FI and BWG were reduced while FCR and feed cost of gain were increased (P<0.05) above 30% protein replacement. Dressing percentage assumed the highest value (P<0.05) on 30% replacement. It was concluded that replacing 30% of feed protein with sun-dried CLM protein will maintain growth and reduce cost of pork production. Efficient use of CLM in the diet will be an alternative way of value addition to this by-product.
