The recent ban on animal protein sources as livestock feed has lead to an increased demand for alternative protein sources (Salgado et al., 2001). Soya protein has been suggested as a potential alternative to fishmeal in weaner diets in sustainable pig production systems. However, the digestion of soya products is known to be reduced by the presence of antinutritional factors such as protease inhibitors and lectins (Lallès, 1993). Several methods have been devised to refine soya thereby increasing ileal digestibility’s (Shon et al, 1994). Some of the refined products include isolate soy protein and soybean protein concentrate. The objective of this experiment was to compare the effect of replacing fishmeal (FO) with HP 300 a soya isolate product on growth performance of piglets from weaning to 28 days post weaning under commercial conditions.
