APLIKASI SINBIOTIK UNTUK PENCEGAHAN INFEKSI INFECTIOUS MYONECROSIS VIRUS PADA UDANG VANAME (Litopenaeus vannamei) (Synbiotic Application for Prevention of Infectious Myonecrosis Virus Infection in White Shrimp (Litopenaeus vannamei))
Get PDFThis study aimed to evaluate the effectiveness of dietary synbiotic at different giving frequencies on growth, immune responses, and resistance of white shrimp infected by infectious myonecrosis virus (IMNV). Synbiotic used in this study was combination of probiotic Vibrio alginolyticus SKT-b and prebiotic oligosaccharides extracted from sweet potatoe (Ipomoea batatas L). Doses of probiotic and prebiotic used were 1% and 2% (w/w), respectively. The white shrimps (0.4930.035 g) were divided into five treatments consisting of A and B (without supplementation of synbiotic: (A) positive control; (B) negative control), C (daily synbiotic supplementation), D (twice a week synbiotic supplementation), and E (weekly synbiotic supplementation). After 30 days of feeding trial, white shrimps were infected by IMNV (except negative control). The results showed that daily growth rate of white shrimp on all synbiotic treatments (C, D, and E) ranged from 6.930.025-6.970.019% and had higher values than controls (A and B) (P0.05). Meanwhile, feed conversion value in C and D (1.540.142 and 1.580.117) were lower than controls (P0.05). Supplementation of synbiotic with different frequencies also affected survival rate of white shrimp after the challenge test with IMNV; daily synbiotic supplementation (C) resulted in a 50% higher survival rate than positive control (P0.05). This was associated with immune responses parameters values of synbiotic treatment (before and after the challenge test) which were better than positive control. In conclusion the addition of synbiotic in feed resulted in higher growth performances, immune responses,and resistance of white shrimp to IMNV infection

Get PDFABSTRACT The aim of this research was to asses the acute toxicity of ethanolic extract of malaka leaves using lethal dose 50 (LD50) on mice (Mus musculus). Twenty male mice weighing between 20-30 g were randomly divided into 4 groups (group K1-K4) of 5 mice each. All mice in group K1, K2, K3, and K4 were administered ethanolic extract of malaka leaves with the dose of 2, 4, 8, and 16 g/kg bw, respectively. Single dose of ethanolic extract of malaka leaves were given by oral gavage prior to clinical observation . The observation period was 14 days post administration, for sign of toxicity symptom, weight loss, and mortality. The result showed that no mortality was observed in the experimental animals during this study. Slight reduction of body weight was observed in group K2, K3, and K4, and no toxicity sign was found during fourteen days of observation. The LD50 of ethanolic extract of malaka leaves was higher than 16 g/kg body weight, thus, the substance was practically non toxic substance
