Abstract錛? White shrimp (Litopenaeus vannamei) was fed six different formulations of medicinal herbs (MH) and Bacillus in a feeding trial conducted for 56 days. The survival,growth, digestive enzyme activity, and serum iochemical parameters were assessed.A basal diet without MH and Bacillus was served as the control. At the end of feeding trial,survival ranged from 76.19% to 84.76% with no significant differences (P[0.05) among all groups. Growth measured as final weight, specific growth rate (SGR), protein efficiency ratio (PER), protein productive value (PPV), and feed efficiency ratio (FER) were improved with increased dietary MH and Bacillus. Shrimp fed 0.2% MH and 0.3% Bacillus (Diet 23) were found to have the best growth performance. For shrimp fed Diet 23
final weight and SGR were significantly (P\0.05) higher than for controls. The digestive
enzyme activity of protease and amylase in hepatopancreas and intestines were significantly
(P\0.05) enhanced by the feed supplements, however amylase of the hepatopancreas was not affected. Serum protein and glucose content were enhanced by the supplement of MH and Bacillus. Serum cholesterol in shrimp of high Bacillus level groups was significantly (P\0.05) higher than in the control group. However, no significant difference (P[0.05) in serum Triacylglycerols between supplemented groups and control was found. Results revealed that the combined MH and Bacillus in diet could enhance growth because it can improve digestive enzyme activity and digestive metabolism.
