Abstract

Despite lupins (Lupinus angustifolius) being an economical plant protein ingredient to feed growing and finishing pigs in Australia, the presence of anti-nutritional factors such as oligosaccharides and non-starch polysaccharides has generally restricted high inclusion levels in diets. New cultivars of Australian sweet lupins (ASL) have been released in Western Australia, but these have been bred mainly for improved disease resistance, drought resistance and yield. While these breeding criteria may also have changed nutritional characteristics, no research has investigated the nutritional adequacy of recent cultivars of ASL when incorporated at high levels in diets for grower/ finisher pigs. The aims of this experiment were to 1) evaluate the optimum inclusion level for grower/ finisher pigs of the current major variety of ASL (cv. Mandelup) and 2) examine the effect of a multi-enzyme preparation on the performance of grower and finisher pigs fed the lupin-based diets. The enzyme treatment was included to assess any potential negative effects of feeding high levels of Mandelup to pigs.
