Previous studies demonstrated that Flaxseed has a Biological Value of 67%. Weanling Wistar rats (n=24) were divided in groups that received flaxseed (F), wheat flour (W) or casein (C) diets to compare protein quality effects on body weight gain and nitrogen retention. A forth group received a mixture of casein:flaxseeds (70:30) (CL) to analyze the adverse effects of flaxseeds. Protein concentration was 8 % and all essential nutrient were added following AIN93. Food (FI) and protein intake (PI), initial (Bo) and final (Bf) body weight, body weight gain (BWG) and nitrogen retention (NR) were determined. Statistical analysis was performed using Anova‐SNK (a: p<0.01 respect W; b: p<0.01 respect F). BWG and NR of F were higher than W and lower than C and CL, being C and CL no different. The results are probably due to the different protein quality of the sources and suggest the addition of flaxseed to casein doesn't have an adverse effect on the growth of animals or the ability to retain nitrogen.
