Rabbit meat bekasam is a traditional fermentation product from Indonesia. This study aimed to determine the chemical and microbiological characteristics of rabbit meat bekasam during the fermentation process in order to isolate, characterize (in vitro and in vivo), and identify lactic acid bacteria (LAB) as the probiotic candidate. The chemical contents of bekasam on 7-day fermentation were investigated in explorative and experimental methods in a completely randomized design. A proximate analysis reported a decrease in the moisture content, fat and carbohydrate content, and an increase in protein content. Also, lactic acid content was increased from 0.48% to 1.12%, and pH was decreased from 5.3 to 4.3. Other properties indicated different values, such as bacteria (2.75×106 to 4.45×107 CFU/g), total LAB (3.82×106 to 4.67×108 CFU/g), total yeast (9.89×106 to 3.82×108 CFU/g) and total mould (4.34×101 to 4.86×103 CFU/g). The experiment produced nine LAB isolates, including two probiotics subjected to further 16S rRNA gene analysis, which indicated that Lactobacillus buchneri was the potential probiotic isolate. After being tested on BALB/c mice, L. buchneri could improve the immune system by inhibiting the growth of Coliform and Salmonella.

Kuntana YP, Yurmiati H, Wulandari AP, Syafitri F, Partasasmita R. 2017. The appearance of rabbit skin tissue (Oryctolagus cuniculus) after supplementation of Aloe vera and Spirulina fusiformis. Nusantara Bioscience 9: 268-274. The research is about the appearance of rabbit skin tissue (Oryctolagus cuniculus L.) after supplementation of Aloe vera L. and Spirulina fusiformis Vor. has been done. This study was carried out to find the most effective formulation ofsupplement of A. vera and S. fusiformis as a natural supplement that can generate the best appearance of rabbit skin tissue. The method in this research was a single Complete Random Design (CRD) on 28 male New Zealand White strains rabbits with the age of 16 weeks. The treatments were divided into seven groups with four replications, namely, P0 (negative control ), P1(positive control, vitamin C19 mg/kg BW), P2 (A. vera 74 mg/kg BW), P3 (S. fusiformis 296 mg/kg BW), P4 (A. vera: S. fusiformis, 74: 148 mg/kg BW), P5 (A. vera: S. fusiformis, 74: 296 mg/kg BW), and P6 (A. vera: S. fusiformis, 74: 593 mg/kg BW). The parameters observed were production aspect (hair texture, slaughter weight, skin width, and skin weight percentage) and histological aspect (thickness of skin tissue and the amount of hair follicle). All of the data was analyzed using ANOVA test (P ˃ 95%) and Duncan test (P ˃ 95%). The result showed that the giving of supplement with the basis of the formulation of A. vera 74 mg/kg bw and S. fusiformis 296 mg/kg bw was effective in generating the best appearance of rabbit skin tissue.
