Assessing the bioavailability of l-lysine sulfate compared to l-lysine HCl in rainbow trout (Oncorhynchus mykiss)

A growth trial was conducted to determine relative bioavailability between two commercially available sources of supplemental lysine in rainbow trout. A basal diet, which was formulated to be deficient in lysine while meeting all other known nutritional requirements for rainbow trout was supplemente...

Description
Summary:A growth trial was conducted to determine relative bioavailability between two commercially available sources of supplemental lysine in rainbow trout. A basal diet, which was formulated to be deficient in lysine while meeting all other known nutritional requirements for rainbow trout was supplemented with increasing levels (0.1, 0.2, 0.4 & 0.6%) of l-lysine on an equimolar basis from one of two supplemental lysine sources; l-lysine sulfate (Bio-lys) or l-lysine HCl. Diets were fed in triplicate to groups of rainbow trout (IBW=25±0.6g) for 12weeks using a pair-feeding protocol. Fish which received diets containing supplemental lysine from either source exhibited improved weight gain (p
