The use of probiotics in aquaculture is one of the strategies to reduce consumption of antibiotics and mitigate the impacts on the environment. The purpose of this research was to evaluate the effect of the dietary inclusion of microencapsulated probiotics on some zootechnical parameters in red tilapia fingerlings (Oreochromis sp.). At the experimental station of the University Corporation Lasallina, two separated groups of fingerlings were given a diet with 42% of crude protein, 86% of digestibility and energy 4765,8 Kcal/Kg, but to one of the groups, 1% of microencapsulated probiotics was included. The fry of both groups were weighted and measured at three times, and the zootechnical variables such as feed conversion (FC), specific growth rate (SGR), weight gain (WG), size gain (SG), and survival percentage were statistically analyzed. The results showed p<0.05 statistical significance and confirmed that the fish fed with probiotics had a better performance of the parameters analyzed. [ABSTRACT FROM AUTHOR]

The objective of this research was to test the viability of a native isolate of Lactobacillus brevis in two fermented milky drinks: a drink without prebiotic ingredient and another drink with oat flour (0.5%, p/v) as prebiotic ingredient. The viability of L. brevis was tested at 7, 14, and 21 after inoculation. Drink pH and lactic acid concentration was measured as a function of time (2, 7, 14, and 21 days after inoculation). The isolate was viable in both drinks because its counting plates was higher than 10(6) CFU/mL until day 21st. Between the 7th and 14th day, the rate of growth was higher in the drink that included oat flour, however, at the day 21st the colony density was similar in both drinks.
