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 ...
متن کاملGenetic markers of body composition and carcass quality in grazing Brangus steers.
The somatotropic axis is a major regulatory pathway of energy metabolism during postnatal growth in mammals. Genes involved in this pathway influence many economically important traits. The association of selected SNPs in these genes with carcass traits was examined in grazing Brangus steers. These traits included final live weight, ultrasound backfat thickness (UBFT), rib-eye area, kidne...
متن کاملPreweaning performance and body composition of calves from straightbred Nellore and Bos taurus x Nellore crosses.
The objectives were to evaluate preweaning performance, body composition, and efficiency of calves representing straightbred Nellore (NL), F(1), and 3-breed-cross systems. Energy requirements, milk production, and efficiency of 39 cow-calf pairs were recorded from straightbred NL calves from NL cows (10), crossbred (Angus-sired) calves from NL cows (ANL: 9), and crossbred calves (CC; Canchim-si...
متن کاملEffects of supplemental dietary L-carnitine on growth and body composition of beluga (Huso huso) Juveniles
The effect of feed supplemented with L-camitine at four levels of 0, 300, 600 and 900mg kg-1 on growth performance and body composition of beluga, H. huso, juveniles was evaluate din two separate trials. In the first trial, 180 juveniles (525±9gw) were fed with the test diet for a period of 71 days, and the trial extended to another 126 days in the second phase by randomly selecting 120 juvenil...
متن کاملEffect of dietary synbiotics on growth, immune response and body composition of Caspian roach (Rutilus rutilus)
Effects of dietary synbiotics on growth performance, survival, stress resistance, body composition and immune response in the Caspian roach (Rutilus rutilus) were evaluated. Fish with an initial average weight of 4.14±0.25 g were randomly distributed into tanks (50 fish per tank) and triplicate groups were fed a control diet or diets containing 1 g kg-1 and 2 g kg-1 synbiotics. After an ...
