Growth Performance and Body Composition of Pikeperch (Sander lucioperca) Fingerlings under Dietary L-Carnitine
Growth performance, food efficiency and body composition of pikeperch (Sander lucioperca) were investigated with 1 or 2 g/kg L-carnitine added to the diet. Control diet did not contain L-carnitine. Two hundred pikeperch fingerlings (1.63 g, mean weight) were stocked in each 1 m3 concrete tank and fed equally 6 meals per day for 6 weeks. Higher increment in body weight (5.92 ± 0.37 g), the ...

Extended Abstract Introduction and Objective: The most important factor in adjusting poultry feed consumption is energy, which is correlated with feed cost. The net energy system is more accurate and useful for measuring the energy utilization of poultry. The presence of anti-nutritional compounds such as non-starch polysaccharides (NSPs) and phytate compounds in some poultry feed items ...
متن کاملThe effects of different levels of biogen probiotic additives on growth indices and body composition of juvenile common carp (Cyprinus carpio L.)
An experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, Cyprinus carpio. Four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % Biogen probiotic were used to feed fish. Seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 L capacity. During 60 days of feeding trial, the...
