Effects of dietary excesses of branched-chain amino acids on the metabolism and tissue composition of lake trout (Salvelinus namaycush)

Leucine Affects Growth and Hepatic Growth-Related Factor Gene Expression in Japanese Amberjack Seriola quinqueradiata

“…Excessive leucine causes BCAA antagonism (Yamamoto et al 2004) and decreases body weight in Rainbow Trout (Choo et al 1991), Lake Trout Salvelinus namaycush (Hughes et al 1984), and Indian Major Carp Cirrhinus mrigala (Ahmed and Khan 2006). However, similar to our results, excessive leucine does not affect the body weight of Rainbow Trout (Rodehutscord et al 1997).…”

Dietary branched-chain amino acid valine, isoleucine and leucine requirements of fingerling Indian major carp, Cirrhinus mrigala (Hamilton)

“…The other reason for reduced weight gain and poor feed efficiency in C. mrigala during the present study may be the disproportionate amounts of isoleucine, leucine and valine in the amino-acid test diets of each feeding trial as a disproportionate amount of one amino acid affects the utilisation of other amino acids (Walton, 1985;Coloso et al 1999). Hughes et al (1984) reported that excess dietary valine does not increase the dietary requirement of lake trout for either leucine or isoleucine. For this reason, the effects of dietary excess valine on lake trout are interpreted as amino-acid toxicity rather than an antagonism.…”

Effects of dietary l-tryptophan and lighting conditions on growth performance of European sea bass (Dicentrarchus labrax) juveniles reared in a recirculating water system

“…TRP‐supplementation induced the reduction of body lipid content and liver lipids that may have resulted from the observed reduction in food consumption or may indicate increased energy demands and/or possible amino acid imbalance as was reported in cases where excesses of essential amino acids were offered in fish experimental diets (Nose, 1975; Hughes et al., 1984; Rodehutscord et al., 1997; Papoutsoglou et al., 2005). On the other hand, Kim et al.…”
