KnipBio Touts Success in Comprehensive Rainbow Trout Feed Trial

KnipBio Inc. announced today the successful completion of an extended series of trials studying the efficacy of its single cell protein ingredient KnipBio Meal (KBM) in the diet of fingerling rainbow trout. The trials were done over a six-month period on close to 5000 animals and are some of the most comprehensive dedicated evaluations ever conducted using a single cell protein as an aquafeed ingredient. The trials compared diets containing varying inclusion rates of KBM against multiple standard trout diets. The results confirmed that juvenile trout fed a diet where KBM replaced a portion of other proteins performed equally well or better than trout fed standard diets in terms of weight gain and animal size (length). The experimental populations also generally experienced equal or higher specific growth rates (SGR) and a better feed conversion ratios (FCR) than the control diet populations. -MORE-

KnipBio Sees Promising Results in Independent Trout Feed Trial

A study appearing in Aquaculture Research found KnipBio’s single cell protein has the potential to replace terrestrial proteins as a key ingredient in rainbow trout feed providing a healthier, more sustainable, and potentially lower cost alternative protein source. Aquaculture Research is a peer-reviewed scientific journal covering the latest developments in research on aquaculture. The study was based on feed trials conducted at the University of Idaho’s Hagerman Fish Culture Experiment Station that were designed to test whether feed containing varying amounts of KnipBio Meal (KBM) can serve as a suitable diet for juvenile rainbow trout. The trials were performed over a 12-week period and found no significant difference in weight gain or feed conversion rates for trout fed a diet containing up to 10% KBM compared to standard trout diets. Importantly, the populations fed KBM experienced an average 85% decrease in mortality compared to the control group. -MORE-
