The experimental tilapia, Oreochromis nilotica, were fed with dietary eel diet containing vaccine and probiotics for 1 month, challenged test against Strep. iniae or Strep. agalactise were examined andthe RPS(%) of protective ability were calculated . the result of oral Strep. iniae vaccine experimental groups including Iniae、Iniae*M、Iniae*A1 showed that RPS(%)were 7.4、44.4、14.8, the result of oral Strep. agalactiae vaccine experimental groups including Agalac、Agalac*M、Agalac*A11 showed that RPS(%)were 3.7、88.9、11.1.
The RPS(%) of 3 experimental groups that were fed with eel diet containing microencapsuled-strep. iniae vaccine and microencapsuled-probiotics(Iniae*M+Rhodo*M、Iniae*M+Micro*M、Iniae*M+Bacillus*M)were 96.2%、96.2%、100%, etc; The RPS(%) of 3 experimental groups that were fed with eel diet containing microencapsuled-Strep. agalactiae vaccine and microencapsuled-probiotics(Agalac*M+Rhodo*M、Agalac*M+Micro*M、Agalac*M+Bacillus*M)were 77.8%、74.1%、66.7%, etc.
