摘要:
于1998年10–11月间在荣成市寻山养殖场实验了饲喂具有大麻哈鱼生长激素基因的酵母菌对牙鲆的生长及其血清激素的影响。实验分为对照组和三组实验组,其中对照组的饵料中不含重组酵母菌,实验组的饵料中分别含有重组酵母菌0.25‰、0.50‰、0.75‰( W/ W)。实验表明,通过投喂重组酵母菌,可以增加牙鲆血清生长激素的含量,促进牙鲆的生长。重组酵母菌的含量不同,对牙鲆血清甲状腺素和三碘甲状腺原氨酸的影响也不同。促甲状腺素的含量与牙鲆血清甲状腺激素的含量呈负相关趋势,与生长激素无明显关系。

Abstract:
From October to November in 1998, an experiment was conducted in Rongcheng Xunshan Fish Breeding Factory to analyze the effects of recombinant yeast on the growth and the content of certain hormone in serum of flounder, Paralichthys olivaceus. No recombinant yeast was fed in the controlled group. For the experimental groups, Group I, Group II, Group III, 0.25‰, 0.50‰, 0.75‰ (W/W) recombinant yeast was mixed into the diet to feed the fish. The growth rate (in weight) of the experimental groups were 43.8%, 52.2%, 56.3%, respectively, while the controlled group was 36.6%. The growth rate (in body length) of the experimental groups were 12.6%, 13.5%, 15.9%, while the controlled group was 12.6%. Growth hormone (GH) content in the serum of the experimental fish was 21.34±12.78, 48.40±15.75, 61.94±12.64ng/ml, respectively, while (GH) content in the control group was 15.25±6.81ng/ml. It can be concluded that the recombinant yeast can effectively improve the growth and the GH content of the flounder. The effects of recombinant yeast on the T4and T3 contents were different with the different amount of the yeast in diet. TSH content was related to the T4 content negatively. No obvious direct effects of recombinant yeast on TSH content were observed.
