Abstract

Apparent (APD) and true (TPD) protein digestibility and apparent (AAAA) and true (TAAA) amino acid availability of fish meal and plant protein ingredients utilized in the South African animal feed industry (corn gluten meal, soya bean meal, cottonseed meal, sunflower meal, canola meal, peanut meal, lupins and faba beans), incorporated at 450 g kg )1 into single protein diets, were determined with juvenile South African abalone (Haliotis midae). A correlation coefficient (r) of 0.99 was found between ADP and mean AAAA. Furthermore, amino acid availabilities were relatively consistent within various feed ingredients. The mean amino acid secretion from a protein-free diet was 19.08 mg 100 g )1 dry diet, resulting in a mean increase of 1.88% units over all feed ingredients when comparing TAAA with AAAA. Calculated APD according to APD coefficients determined with single protein diets underestimated determined APD in several compound diets by 1.10-6.50%, while mean AAAA was underestimated by 6.93%.KEY WORDS

Combination of lysine and histidine improves growth performance, expression of muscle growth‐related genes and fillet quality of grow‐out Nile tilapia

“…Otherwise, the current findings do not support previous research in carp, C. catla (Zehra & Khan, 2014), who reported the effects of histidine on the hepatosomatic index and visceral fat ratio in catfish (Farhat Fish fed diets supplemented with lysine and histidine individually or in combination revealed lower whole-body lipids than those fed other diets in the present study. Similar trend results were previously described in Atlantic salmon (Berge et al, 2002), gibel carp, Carassius auratus gibelio (Xie et al, 2001), pacu, Piaractus mesopotamicus (Bicudo et al, 2009), Indian major carp, Labeo rohita (Sardar et al, 2009), black seabream, Sparus macrocephalus (Zhou et al, 2010), Atlantic salmon (Grisdale-Helland et al, 2011) and turbot, Scophthalmus maximus (Yang et al, 2011) fed lysine-added diets.…”

“…Alterations in the nutritional status modify the hepatosomatic index and the reduction in the visceral fat ratio in fish offered unbalanced amino acid diets (Khan & Abidi, 2014;NRC, 2011). A similar pattern of results in response to amino acids supplementation was previously reported in Atlantic salmon (Berge et al, 2002) and Nile tilapia (Furuya et al, 2006;Michelato, de Oliveira Vidal, et al, 2016).…”
