Lysine requirements of tambatinga (♀ Colossoma macropomum × ♂ Piaractus brachypomus ) fingerlings using different diet formulation techniques

Requirement of fingerling Channa punctatus (Bloch) for dietary lysine based on growth, feed conversion and lysine retention efficiency, RNA/DNA ratio, haematological parameters and serum antioxidant activity

“…Fish-fed lysine deficient diets (5g/kg) showed reduced WG, SGR and PRE, while dietary lysine supplementation improved growth and feed utilization efficiency. Earlier workers reported this pattern of weight gain in several other fish species (Abidi & Khan, 2010;Ahmed, 2017;Campelo et al, 2018;Ebeneezar et al, 2019;Farhat, & Khan, M. A., 2013;Li et al, 2020;NRC, 2011;Sousa et al, 2021;Xie et al, 2012) indicating that availability of the required amount of lysine improves the growth of this fish. Fish fed higher levels of dietary lysine showed reduced growth,…”

Blochii (Ebeneezar et al, 2019); sciaenid, P. diacanthus (Li et al, 2020); P. ussuriensis ; tambatinga, C. macropomum × P. brachypomum (Sousa et al, 2021); and grass carp, C. idellus (Huang et al, 2021) as also in C. punctatus, the fish under study. Low feed efficiency, depressing growth and mortality due to lysine deficiency were observed in this fish.…”

“…The diets were labelled as Ly 5 , Ly 10 , Ly 15 , Ly 20 , Ly 25 , Ly 30 and Ly 35 . The dietary doses of lysine were adjusted taken with respect to the lysine requirements of other fish species (Ahmed, 2017;Adesola et al, 2018;Ebeneezar et al,2019;Farhat, & Khan, M. A., 2013;Huang et al, 2021;Li et al, 2020;NRC, 2011;Sousa et al, 2021;Zehra & Khan, 2013). Analysed lysine concentrations were found to be 4.…”

Exigência De Aminoácidos Essenciais Para Peixes Redondos

“…Por outro lado, dietas com alto níveis de energia, podem limitar o consumo e sub-estimar a exigência (PORTZ;FURUYA, 2012;SANTOS et al, 2022). Além disso, devemos levar em consideração as metodologias empregadas formulação das dietas e a utilização de dietas purificadas ou práticas (WILSON, 2002;BICUDO, SADO;CYRINO, 2009;MARCHÃO et al, 2020;DA COSTA SOUSA et al, 2021).…”
