摘要

Stafac-20, a commercial growth promoting feed additive containing 2% virginiamycin, was added at 0, 20, 40, 60, 80 and 100 ppm levels to the basal diet having 35% protein, prepared incorporating fish meal, groundnut oilcake, rice bran, tapioca flour and vitamin-mineral mixture. The effect of these diets (T_0, T_1, T_2, T_3, T_4 and T_5) was evaluated on growth, body composition and digestive enzyme . activity of mahseer, Tor khudree fingerlings through an experiment conducted over 140 days. Fingerlings of average weight 1.4 g + 0.04 stocked in 25 m~3 outdoor cement tanks were fed on the test diets in triplicate. Addition of the additive resulted in significant (P<0.05) increase in fish weight gain, the best being with 60 ppm Stafac-20 inclusion. The highest fish survival, feed conversion efficiency, RNA: DNA ratio and net fish production were obtained in this treatment. Body composition and digestive enzyme activity were positively affected in the treated fish. The results indicate the beneficialeffects of adding Stafac-20 to the diet of mahseer.
