The research aims to analyze the impacts of immunostimulant yeast (Saccharomyces cerevisiae) supplemented feed on growth rate and blood profile in Java Barb [Barbonymus gonionotus (Bleeker, 1850)] fingerlings. The Java Barb of 200 fingerlings had an average weight of 5.64 g ± 0.87 g, and an average length of 6.32 cm ± 0.58 cm. The experiments employed a Completely Randomized Design with five treatments, and each had four repetitions for a period of 49 d (days). Various dosages of S. Cerevisiae were added to the feed. The treatments were T1 (0 g kg−1 feed), T2 (1 g kg−1 feed), T3 (2 g kg−1 feed), T4 (3 g kg−1 feed), and T5 (4 g kg−1 feed). The results showed that yeast as supplemented feed could boost the growth and blood profiles of Java Barb. The blood profiles include improvement in total blood cells (TCC μL–1), red blood cells (RBC), white blood cells (WBC), hematocrit (HTC) compared to control. The highest value of efficiency of feed utilization (EFU) was 72.36 % and followed by FCR (feed conversion ratio), PER (protein efficiency ratio), RGR (relative growth rate), and SR (survival rate) with the values of (1.63, 4.21, 4.18) % d−1, and 92.33 % respectively. The optimal dosages of S. cerevisiae in the feed for EFU, FCR, PER, and RGR ranged from 2.38 g kg−1 feed to 3 g kg−1 feed. [ABSTRACT FROM AUTHOR] |
