The effect of probiotics (RABAL) on application in diet with different doses on growth, survival and feed conversion of Barramundi (Lates calcarifer)

Abstract

The study aimed to determine the effect of RABAL probiotics with different doses to improve Barramundi growth, survival and feed conversion. This research was conducted from March to April 2019 at Balai Perikanan Budidaya Air Payau. This study uses a Completely Randomized Design (CRD), which consists of controls namely without the administration of probiotics and 3 treatments given with various doses of probiotics, namely 10 mL / 100 gr feed, 20 mL / 100 gr feed, 30 mL / 100 gr feed. Based on the best ANOVA test results at the treatment is 20 mL / 100 gr with absolute weight growth of 3,09 - 0,27, absolute length growth of 2,52 - 0,09, specific growth rate of 4,5 - 0,20, survival 99 - 4,79, and feed conversion ratio 0,90 - 0,07. The results of the study showed that different dosages of RABAL showed significantly different results (P <0,05) on absolute weight, absolute length, specific growth rate, survival and feed conversion.
