Abstract
Recent selections of Yellow Lupins (YL) have been found to have a higher crude protein content than that of Australian Sweet Lupins (ASL) (L. angustifolius) (380 vs 310 g/kg, respectively) and to yield better than ASL varieties on low fertile acid soils (700 vs 470 kg/ ha, respectively) (Cowling, unpublished). Mullan et al. (1997) concluded that YL have the potential to be a high quality feedstuff for growing pigs based on the results of a study where pigs were fed diets containing up to 260 g/kg of the seed to pigs between 20 and 55 kg liveweight (LW). However, as part of the testing of seed from the Agriculture WA breeding program it was found that cadmium (Cd) levels in YL were higher than in ASL (Peterson, unpublished). Although still below the international standard for Cd in stockfeed, there was some concern that this might limit its potential market as a stockfeed. The aims of this experiment were to: (i) measure the retention of Cd in body tissues of pigs that had been fed a diet containing high levels of YL over an extended period of time, and (ii) to measure the performance of pigs fed diets that contain varying proportions of YL as a replacement for soybean meal.
