研究了在饲料中添加嗜酸乳杆菌（ Lactobacillus acidophilus）对大菱鲆生长的影响。嗜酸乳杆菌为从健康大菱鲆肠道中分离、培养的同源嗜酸乳杆菌，活菌数2．0×109 CFU/g，其在饵料中的添加量分别为0‰（对照组）、5‰、10‰和15‰，连续投喂20 d、40 d、60 d后，结果表明，5‰添加组的饲料系数分别降低8．8％、4．4％、1．5％，蛋白质效率分别提高2．7％、3．5％、2．0％；10‰添加组的饲料系数分别降低3．0％、1．5％、-7．2％，蛋白质效率分别提高3．7％、1．1％、-6．0％；15‰组促生长指标均低于对照组。研究表明，在投喂早期，添加5‰嗜酸乳杆菌的饵料对大菱鲆生长的促进效果较好，但随着添加时间的延长，该作用逐渐减弱，并最终低于对照组。

This paper studied the effect of Lactobacillus acidophilus preparations on turbot growth .L.acidophilus was isolated from the healthy turbot intestinal tract and cultured homologous L.acidophilus, which viable count 2.0 ×109 CFU/g.The addition amount of bait was 0‰, 5‰, 10‰ and 15‰.After 20 d, 40 d and 60 d continuous feeding , compared with the control group , 5 ‰group decreased feed conversion ratio of 8.8%, 4. 4%, 1.5%, protein efficiency of 2.7%, 3.5%, 2.0%;10‰group feed conversion ratio decreased by 3.0%, 1.5%, -7.2%, protein efficiency of 3.7%, 1.1%, -6.0%;15‰group promoting growth were lower than the control group .These results showed that:only the diet which contained 5‰L.acidophilus promoted growth of turbot , and it was just in early experimental stage .With the extension of L.acidophilus diet feeding , the promoted growth effects weakened gradually and lower than the control group eventually .
