Dietary lysine and methionine requirement of bream Abramis brama orientalis juvenile
Data de publicação: 01/08/2012
This study was conducted to estimate the dietary lysine and methionine requirement of juvenile Abramis brama orientalis based on growth performance. Juveniles (initial body weight, 0.80±0.08 g) fed 3 times daily with 5% body weight per day with the basal diet containing 0.3 and 0.6% lysine and methionine alone or in combination. The juveniles were cultured in indoor tanks with three replicates per dietary treatment. Bream juveniles fed the diet contained both lysine and methionine at 0.6% showed relatively higher specific growth rate and slightly lower feed conversion ratio at the end of the feeding trial. On the other hand, diet supplemented with both lysine and methionine has better improved the growth rate of the juveniles.
