  1. Initial and final weights (n = 250), SGR (pit-tags) (n = 20), VSI (n = 12), HSI (n = 12) and CF (n = 12) Moisture, Protein, Lipid, Ash (n = 3) are all means ± SD. Significance of differences between means were determined by one -way ANOVA followed, where appropriate, by Tukey's multiple comparison test as described in the Materials and Methods. Values within a row with a different superscript letter are significantly different (P ≤ 0.05). CF, condition factor = 100 × [(body weight (g)/body length (cm)]3; FCR, feed conversion ratio = feed consumed (kg)/weight gain (kg); HSI, hepato-somatic index = 100 × (liver weight × body weight-1); SGR, specific growth rate (%/day) = 100 × [(ln weight final – ln weight initial) × days-1]; VSI, viscero-somatic index = 100 × (carcass weight × body weight-1). P/L, Protein:Lipid ratio.
