嗜酸乳杆菌对大菱鲆生长促进作用的研究
Study on the effect of Lactobacillus acidophilus on promoting growth of turbot Scophthalmus maximus(Linnaeus)
摘要
Abstract
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 .关键词
