| Abstrak/Abstract |
Aims of this study were to determine the effect of probiotic application on the
growth performance and feed utilization of red tilapia nilasa strain juveniles. Yeast and
bacterial strains of different origin (Saccharomyces sp., Enterobacter sp. JC10, Aeromonas sp.
JC33, and Lactococcus sp. JAL12) were administered to fish in daily and three day intervals at
dose of 5x104 CFU/gram feed. The control groups were only administered with fish pellet with
saline buffer. The fish were stocked in 95 × 72 × 55 cm containers (50 each) and fed
approximately 3 % of their body weight thrice a day for 62 days. Absolute, relative and
specific growths of weight were examined at one and two months of probiotic application.
Fish survival rate, total production, feed conversion ratio (FCR) were analyzed at the end of
experiment. The results showed that probiotics application in fish affected absolute weight,
relative weight, specific weight, and total production (P<0.05). No significant effects on fish
feed utilization parameters were obtained. It is concluded that probiotics SEAL application is
efficacious in the growth performance of tilapia nisala strain. The application with three-day
interval improves the growth and total production of red tilapia similar to the daily probiotics
application. |
