Apparent total tract digestibility of unprocessed and extruded diets containing basic and autolyzed bacterial protein meal grown on natural gas in mink and rainbow trout

A study was conducted to compare coefficient of total tract apparent digestibility (CTTAD) of diets where high-quality (LT) fish meal (FM) were partly replaced with basic bacterial protein meal (BPM) and autolyzed bacterial protein meal (BPA) in a carnivorous mammal (mink) and fish (rainbow trout)....

Zusammenfassung:	A study was conducted to compare coefficient of total tract apparent digestibility (CTTAD) of diets where high-quality (LT) fish meal (FM) were partly replaced with basic bacterial protein meal (BPM) and autolyzed bacterial protein meal (BPA) in a carnivorous mammal (mink) and fish (rainbow trout). In mink, both unprocessed meal and extruded diets were tested, while only extruded diets were tested in rainbow trout. Adding BPM (0, 125 and 250 g kg −1) to diets had no effect on CTTAD of macronutrients in the unprocessed diets, but decreased the CTTAD of starch (linear P
