Nutritive evaluation, metabolisable energy and digestible amino acid contents of different indigenous feedstuff for Nile tilapia (Oreochromis niloticus)

Abstract Three trials were executed to examine the nutritive profile, metabolisable energy and digestible amino acid (AA) contents of four indigenous feed ingredients including wheat (W), middling (WM), canola meal (CM) rapeseed (RSM) in Nile tilapia. samples each test ingredient collected from three different locations Multan (MUL) Sukkar (SKR), Pakistan. The pooled thereafter make a homogenous/ representative sample particular study site. Nutrients composition, AA digestibility these evaluated by using laboratory analyses fish studies. Proximate analysis indicated variations some nutrients due location (p < 0.05). Differences also observed arginine, lysine, serine, cysteine, glutamic aspartic acids, histidine, valine glycine Digestibility leucine, was higher 0.05) RSM MUL. Among W MUL, for threonine, Crude protein, alanine, had 0.05), whereas lower tyrosine Metaboliseable did not differ among W, WM, CM regarding their origin > results that nutritional profiles indices vary with
