Abstract
This research evaluated the dietary effects of Lupinus angustifolius meal (LM) replacing corn gluten meal (CGM) on growth performance of Kikuchi minnow (Aphyocypris kikuchii). Kikuchi minnow (0.42 g) were fed for 6 weeks (42 days) on diets contained LM to substitute 0, 5, 10, 15 or 20% with CGM. Fishes were assigned randomly to 5 experimental tanks with different diets, and each diet was fed to triplicate groups of 15 fishes. The results showed there had no significant difference between the diets replaced with 0% LM and 10% LM on percent weight gain (WG): 44%, 38% and feed efficiency (FE): 26%, 23%. Protein content of whole fish body decreased with the higher replacement in diet by LM. Protein efficiency rate (PER) and daily N increase per hundred gram body weight (mg/100g b.w.) had no significant difference between diet replaced with 0% LM and 10% LM. However, WG, PER and daily N increase (mg/100g b.w.) were significant lower in diet replaced with 15% LM than 10% LM. In conclusion, the proper level of replacing CGM with LM for Kikuchi minnow is 10%.
