Synbiotic application shows better results compared to the single use of probiotics or prebiotics. SKT-b bacteria have been shown to act as probiotics for aquatic animals, as well as sweet potatoes that are known to act as prebiotics. This study aims to examine the synbiotic potential of SKT-b probiotic bacteria and oligosaccharide extract from sweet potato in improving the growth performance of vaname shrimp. Shrimp were treated with synbiotic feed with different prebiotic concentrations of 1% (Pro + Pre 1%), 2% (Pro + Pre 2%) and 3% (Pro + Pre 3%). The treated food was given to shrimp (weight ± 1.9 g) for 30 days. Oligosaccharides extracted from sweet potato can act as a prebiotic which increases the bacterial population in vaname shrimp’s intestine. The application of synbiotics can improve the growth performance of vaname shrimp including the addition of body weight, feed efficiency, digestive enzyme activity, protein retention and body fat of shrimp. The treatment of Pro + Pre 2% and Pro + Pre 3% shows better growth performance of vaname shrimp.

ABSTRACT This study aimed to investigate the effects of probiotic (Bacillus NP5), prebiotic (extracted from Ipomoea batatas var. sukuh,), and synbiotic on growth and digestive enzyme activity of dumbo catfish (Clarias sp.). Four treatments with 3 replications were used in the experiment, i.e; control, probiotic (1% Bacillus NP5 in feed), prebiotic (2% sweet potato extract in feed), and synbiotic (1% probiotic and 2% prebiotic in feed). After 45 days of rearing, catfish that were given probiotic, prebiotic, and synbiotic showed significantly (P<0.05) higher growth than that of the control. The average results on digestive enzyme activities in probiotic, prebiotic, and synbiotic treatments were significantly different (P<0.05) from that of the control. The addition of synbiotic to diets showed the best result on final weight, specific growth rate, feed conversion ratio, protein retention, protein efficiency ratio, and protease activities among other treatments. Keywords: catfish, growth, probiotic, prebiotic, symbiotic  ABSTRAK Penelitian ini bertujuan untuk menginvestigasi pengaruh dari probiotik (Bacillus NP5), prebiotik (ekstrak ubi jalar varietas sukuh), dan sinbiotik terhadap pertumbuhan dan aktivitas enzim perncernaan ikan lele dumbo (Clarias sp.). Penelitian terdiri dari 4 perlakuan dan 3 kali ulangan, yakni: probiotik (Bacillus NP5 sebanyak 1% dalam pakan), prebiotik (ekstrak ubi jalar sebanyak 2% dalam pakan), dan sinbiotik (Bacillus NP5 1% + ekstrak ubi jalar sebanyak 2% dalam pakan). Setelah pemeliharaan selama 45 hari, ikan lele pada perlakuan dengan suplementasi probiotik, prebiotik, dan sinbiotik dalam pakan secara signifikan (P<0,05) menghasilkan pertumbuhan yang lebih baik dibandingkan dengan kontrol. Nilai aktivitas enzim pencernaan pada perlakuan probiotik, prebiotik, dan sinbiotik secara signifikan berbeda (P<0,05) dari kontrol. Penambahan sinbiotik pada pakan memberikan hasil terbaik pada parameter bobot akhir, laju pertumbuhan harian, FCR, retensi protein, rasio efisiensi protein, dan aktivitas enzim protease dibandingkan dengan perlakuan lainnya. Kata kunci: ikan lele, pertumbuhan, probiotik, prebiotik, sinbiotik.

The use of probiotics (Lactobacillus  sp.) in feed is one alternative that is done to improve immunostimulants, growth stimulants, and can be used as a balance of microorganisms in digestion. This study aimed to evaluate the growth performance of vanamei shrimp fed with the addition of Lactobacillus  sp. with sweet potatoes in feed. This study used a completely randomized design (CRD) with 4 treatments and 3 replications. The treatment was by feeding with different sweet potato concentrations: A) The dose of sweet potato in feed was 0% (as control); B) The dose of sweet potato in feed was 10%; C) 1The dose of sweet potato in feed was 15%; and D) The dose of sweet potato in feed was 20%. Data were analyzed using variance analysis (ANOVA) and continued with W-Tuckey's further test. The research parameters were digestive enzyme activity, nutrient digestibility, and growth. The results of the variance analysis showed the addition of various sweet potato concentrations with Lactobacillus sp. has no significant effect (p> 0.05) of the growth rate. The specific growth rate of vannamei shrimp ranges from 3.06 to 3.23% / day. Based on the results of the analysis on the utilization of sweet potatoes as a prebiotic on the performance of Lactobacillus sp. in the vannamei shrimps (Litopenaeus vannamei) digestive tract can be concluded that the growth performance does not have a significant effect after being fed with the addition of Lactobacillus sp. and sweet potatoes in feed.

A 60-days feeding experiment was conducted to evaluate the utilisation of sweet potato leaf meal (SPLM) for replacement of de-oiled rice bran (DORB) in the diets of rohu Labeo rohita (Hamilton, 1822) fingerlings. SPLM has good protein content (22.12%) and digestible energy content (11.81 MJ kg-1). Five iso-nitrogenous (30%) and iso-caloric diets (13.5 MJ kg-1) were prepared by replacing DORB with sweet potato leaf meal (SPLM) at 0% (C), 25% (T1), 50% (T2), 75% (T3) and 100% (T4). Each dietary treatment was tested in triplicates with 12 fingerlings per tank, following completely randomised design. The growth performance and feed utilisation parameters viz., weight gain % (WG), specific growth rate (SGR), protein efficiency ratio (PER) and feed conversion ratio (FCR) were not significantly different (p>0.05) among treatments. The digestive enzyme activity remained unaffected except amylase activity, which increased significantly in 50% SPLM replacement group (T2). Chymotrypsin decreased significantly (p<0.05) in the treatment groups. Metabolic enzymes viz., ATPase activity of liver increased significantly (p<0.05) whereas ALP (alkaline phosphatase) activity in the intestine had irregular pattern. The present study indicates that DORB can be completely replaced by SPLM without affecting growth performance and digestive enzyme activity in the diet of L. rohita.

This study was aimed to evaluate the utilization of hydrolyzed Indigofera zolingeriana by celullase enzyme as the feed ingredient of gourami fish. This study used a completely randomized design which contained three steps, whereas each step contained four treatments and four replications. The first step performed by evaluating the Indigofera leaf meal (ILM) added with cellulase enzyme of 0 g/kg (control), 0.4 g/kg, 0.8 g/kg, and 1.2 g/kg. The second step was the digestibility test of ILM on gourami seeds. The third step was feed evaluation added with ILM as much as 0% (control), 15%, 30%, and 45% against the growth performance on gourami seeds. The gourami seeds used in the second and third steps with a weight of 13.65 ± 0.39 g/seed and 5.95 ± 0.15 g/seed, respectively. The addition of 0.8 g/kg and 1.2 g/kg cellulase enzyme could significantly decrease the crude fiber of ILM with 43.33%, besides having the best value of total, ingredient, protein, lipid, and energy digestibility. The growth performance of gourami seeds given 15% ILM added feed had the best value and insignificantly different from the control feed without ILM addition based on the specific growth rate (SGR), protein retention (PR), and feed efficiency (FE).          Keywords: Cellulase, feed, hydrolyze, Indigofera zolingeriana, Osphronemus gouramy.   ABSTRAK   Penelitian ini dilakukan untuk mengevaluasi pemanfaatan daun Indigofera zolingeriana yang dihidrolisis enzim selulase sebagai bahan baku pada pakan benih ikan gurami. Penelitian ini menggunakan rancangan acak lengkap yang terdiri atas tiga tahap, dimana masing-masing tahap terdiri dari empat perlakuan dan empat ulangan. Pada tahap pertama dilakukan evaluasi tepung daun Indigofera (TDI) yang ditambahkan enzim selulase sebesar 0 g/kg (kontrol), 0.4 g/kg, 0.8 g/kg, dan 1.2 g/kg. Pada tahap kedua dilakukan uji kecernaan bahan TDI pada benih ikan gurami. Pada tahap ketiga dilakukan evaluasi pakan yang ditambahkan TDI sebesar 0% (kontrol), 15%, 30% dan 45%  terhadap kinerja pertumbuhan pada benih ikan gurami. Benih ikan gurami yang digunakan pada penilitian tahap kedua dengan bobot 13.65 ± 0.39 g/ekor dan 5.95 ± 0.15 g/ekor. Penambahan enzim selulase pada dosis 0.8 g/kg dan 1.2 g/kg secara signifikan mampu menurunkan serat kasar TDI sebesar 43.33 % dan memberikan nilai terbaik terhadap nilai kecernaan total, kecernaan bahan, kecernaan protein, kecernaan lemak dan kecernaan energi. Kinerja pertumbuhan benih ikan gurami yang diberikan pakan yang ditambahkan TDI sebesar 15% memilki nilai terbaik dan tidak berbeda nyata terhadap pakan kontrol tanpa TDI dari aspek laju pertumbuhan spesifik (LPS), retensi protein (RP) dan efisiensi pakan (EP).   Kata kunci: Hidrolisis, Indigofera zolingeriana, Osphronemus gouramy, pakan, selulase.
