Excessive accumulation of arsenic (As) in rice (Oryza sativa L.) may pose a health risk to rice consumers. Long-distance transport of As within plant tissues is not well understood. The aim of our study was to evaluate As translocation from roots to shoots and from shoot tissues to rice grain. At the grain filling stage, 73As-labelled arsenite was fed to(More)
A 12-week experiment was conducted to quantify dietary lysine requirement of fingerling Catla catla (3.65 ± 0.05 cm; 0.58 ± 0.02 g) by feeding casein–gelatine-based diets (33.0 % crude protein; 14.3 kJ/g digestible energy) with six levels of l-lysine (1.25, 1.50, 1.75, 2.00, 2.25 and 2.50 % dry diet). The experiment was conducted in eighteen 70-L indoor(More)
In order to determine the dietary isoleucine requirement of fingerling catla, Catla catla (4.25 ± 0.15 cm, 0.61 ± 0.04 g), six isonitrogenous (33.0 % crude protein) and isocaloric (13.7 kJ/g digestible energy) amino acid test diets containing casein, gelatin and l-crystalline amino acids with graded levels of isoleucine (0.5, 0.75, 1.0, 1.25, 1.5 and 1.75 %(More)
An 8-week feeding trial was conducted in a flow-through system (1–1.5 L min−1) at 27°C to determine dietary protein requirement for Channa punctatus fingerlings (4.58 ± 0.29 g) by feeding six isocaloric diets (18.39 kJ g−1, gross energy). Diets containing graded levels of protein (300, 350, 400, 450, 500 and 550 g kg−1) were fed to triplicate groups of fish(More)
This study aimed at quantifying leucine requirement of fingerling Catla catla [3.75 (mean body length) ± 0.15 (SE) cm, 0.66 (mean body weight) ± 0.04 (SE) g] by conducting a 12-week feeding trial. Six casein- and gelatin-based (33 % crude protein, 14.0 kJ g−1 calculated digestible energy) semipurified diets containing different concentrations of leucine(More)
A 12-week feeding trial was conducted to evaluate the effects of varying levels of dietary arginine on growth, feed conversion, protein productive value and carcass composition of fingerling Heteropneustes fossilis (10.11 ± 0.14 cm; 5.87 ± 0.07 g). Casein and gelatin-based isonitrogenous (38% crude protein) and isocaloric (14.72 kJ g−1 digestible energy)(More)
