영문 초록

This study was conducted to investigate effects of dietary recombinant bovine somatotropin (rBST) to moist pellet (MP) diet on growth and body composition of olive flounder (Paralichtys olivaceus). Experimental fish (average body weight:25 g) were divided into 4 groups, and each group was fed MP (raw fish and commercial compound meal was 7:3) with rBST addition levels 0, 2, 4 and 6 ppm/㎏ for 8 weeks. The growth and feed efficiency of the rBST addition groups was significantly higher than that of the control group (P＜0.05), and there were no significant difference with the rBST addition levels. Moisture, crude protein, crude lipid and crude ash content of whole body and liver in olive flounder were not significantly different between experimental groups. But crude lipid content of dorsal muscle and viscera of rBST addition groups were significantly lower than that of the control group. HSI (hepatosomatic index), VSI (visceralsomatic index), CF (condition factor), Ht (hematocrit) and Hb (hemoglobin) were not significantly different between experimental groups. The results indicate that the addition of 2 ppm/㎏ MP diet can improve growth and feed efficiency.
