Khả năng sử dụng bã cải ngọt (Canola) thay thế bánh dầu đậu nành cho cá tra (Pangasianodon hypophthalmus Sauvage, 1878)

A 180-day feeding trial was conducted with Pangasianodon hypophthalmus fingerling (initial weight  of  12.40  ±  0.04  g)  to  examine  the  effects  of  partial  substitution  of  canola  meal  in prepared  diets  on  growth,  feed  conversion  ratio  (FCR),  somatic  indices,  and  survival  rate. Four  isonitrogenous  (30%  crude  protein  and  5.5%  crude  lipid)  diets  were  formulated  to contain 10%, 20% and 30% canola meal against no canola meal (control group). A total of 1,280 tra catfish were distributed into 4 experimental groups with 4 replicates. At the end of the experiment, there were no significant differences on growth, feed conversion ratio (FCR), somatic  indices,  and  survival  rate  (P  >  0.05).  This  study  showed  that  canola  meal  could replace  standard  diets  by  up  to  30%  in  Pangasius  catfish  without  adversely  affecting performance.
