Protein and energy needs for maintenance and growth of Nile tilapia (Oreochromis niloticus)

Abstract

A trial was undertaken with juvenile Nile tilapia fed graded levels of dietary protein (C-35% DP) over 7 weeks (28 "C). Measurements of nitrogen and energy utilization were made using data on ADC, comparative carcass analyses, nitrogen excretion and oxygen uptake. Data indicate that the daily rotein intake for maximum N gain was c. 12 g/k /d and the maintenance rotein requirements were ,gout of 2 g/kg/d. The optimal DP/DE ratio was found to be 18 mg/kJ. Differences were observed in the data on endogenous nitrogen and energy utilization depending on the dietary treatments as well as on the criteria used.

Feeds, water quality, gut morphology and digestion in Nile tilapia (Oreochromis niloticus)

“…The same trend was also observed with fish fed the DDGS diet. Except for hydrolysed feather meal, the protein efficiency values reported in the current study are comparable to other studies for Nile tilapia (Kaushik et al, 1995, Tran-Duy et al, 2008b, Figueiredo-Silva et al, 2013.…”

Dietary utilisation of protein and energy from fresh and ensiled coffee pulp by the Nile tilapia, Oreochromis niloticus

“…Upon analysis, frozen fishes were chopped, lyophilised and ground to obtain a homogenous dry fine powder. , respectively, according to Nile tilapia requirements (Kaushik et al, 1995). This was referred as 100 % protein and 100 % energy supply.…”

Effect of varying protein levels on growth and digestive enzyme activities of pengba Osteobrama belangeri (Valenciennes, 1844)

“…The essential amino acids (EAA) and non-essential amino acids (NEAA) incorporated in the fish feed help to synthesise body protein and provide energy for metabolic activity (Lovell, 1989;Kaushik et al, 1995). Studies on protein requirements of carps have been undertaken by many workers using casein based synthetic diets (Mahanta et al, 2008;Ismat et al, 2013).…”
