| Abstract |
A novel in vitro digestion system, which simulated rainbow trout (Oncorhynchus mykiss) gastric and intestinal digestion was developed. The method was employed to evaluate the impact of the gastric phase of digestion upon degradation of three fish meals of differing quality. Results illustrated that two-phase gastric-intestinal digestion increased the discriminatory powers of the system when compared to one-step intestinal digestion. A comparison of the system with PH-STAT methods demonstrated that the in vitro technique was superior. The presented method provides an ethical and cost effective means for rapid evaluation of fish meals and potentially, alternative protein sources for aquafeeds. |
