Effects of supplemental dietary L-carnitine on growth and body composition of beluga (Huso huso) juveniles
The effect of feed supplemented with L-carnitine at four levels of 0, 300, 600 and 900mg kg-1 on growth performance and body composition of beluga, H. huso, juveniles were evaluated in two separate trials. In the first trial, 180 juveniles (525±9gw) were fed with the test diet for a period of 71 day...
