Abstract

This study was conducted to obtain xylanolytic mutants that have higher xylanase activity than their wildtype counterparts. A mutant with the best xylanolytic activity was selected and identified based on its 16S rRNA sequence. Its optimum growth condition was also characterized and its phylogenetic relations to other xylanolytic bacteria were analzsed. Wild type xylanolytic alkalophlic bacteria were grown in medium containing xylan as a substrate. Mutation was performed using ethidium bromide (EtBr) or ethyl methanesulfonate (EMS) atconcentrations 50, 100, and 150 mg mL-1 and times of exposure 30, 60, 90, and 120 min for each treatment. Twenty two mutants were obtained from EtBr and 24 mutants from EMS mutageneses. The mutants were analyzed for their capability to secrete xylanase into xylan medium containing xylose or glucose or glycerol. Growth optimizations of the mutant were done in media with pH range 6-11 and temperature range 30 to 60 °C. Mutant number 19, which was obtained by treatment using 50 mg mL-1 EMS for 120 min, had the highest xylanase activity (15.057 U g-1). This activity was obtained at optimum growth conditions: pH 9.5 and temperature 55 °C. Chromosomal DNA of this mutant was extracted and amplified by PCR using 16S rRNA gene specific primers. The amplified fragments were sequenced by dideoxynucleotide chain terminator method. The phylogenetic analysis based on 16S rRNA gene sequence showed that mutant 19 was closed to an anaerobic xylanase producing bacteria.

Abstract

Aflatoxin B1 is a toxin produced by the fungus Aspergillus flavus which reduces the development and function of organs in broilers. The aim of this study was to determine the effect of adding binder toxin from different bentonite to feed contaminated with AFB1 on productivity, intestinal morphology, and liver toxicity in broilers. A total of 60-day old chick male broilers were placed in 12 pens. Each treatment consisted of three replicates, each replicate containing five broilers. Treatment in the study consisted of P0 (control, basal diet, without the addition of AFB1), P1 (P0 + 100 µg/kg AFB1 + 4 g/kg calcium bentonite Type A), P2 (P0 + 100 µg/kg AFB1 + 4 g/kg calcium bentonite Type B), and P3 (P0 + 100 µg/kg AFB1 + 4 g/kg calcium bentonite Type B + kerolite + saponite). Treatment diets were given to broilers from day 22 to 35 (finisher phase). The results showed that the toxin binder on AFB1 contaminated feed had no effect on feed consumption, body weight gain and feed conversion (p>0.05). Addition of toxin binder on AFB1 contaminated feed increased the relative weight of the duodenum (p=0.024), although P3 was not significantly different. Treatments had no effect on villus length, crypt depth, and ratio of villus length to crypt depth (p>0.05), but decreased villus width (p=0.013). The addition of toxin binder tended to decrease the villus area (p=0.055). SGOT and SGPT did not show differences between treatments. AFB1 contamination with the addition of toxin binder showed signs of toxicity on liver histopathological observations. Based on the research, it can be concluded that the addition of binder toxin in feed contaminated with AFB1 can reduce the negative effect on the development of intestinal villus and chemical effect to the liver. Toxin binder Type B has the best efficacy for reduce the negative effect

Abstract

Lactic acid bacteria are bacteria used to ferment food. Molecular identification of isolates of lactic acid bacteria has a high degree of accuracy compared to morphological identification. This study aimed to molecularly identify isolates of lactic acid bacteria from broiler chickens. Molecular identification is carried out in 3 stages, namely: rRNA gene amplification stage, squencing and phylogeny tree. PCR electrophoresis results obtained amplicone results measuring about 1,500 bp. The results of BLAST analysis showed that the gen 16S rRNA sequence of BR 17 lactic acid bacteria isolate had a 97-98% similarity with the genome sequence of the Lactobacillus fermentum strain.  Development of phylogenetic tree isolates of single clusters of lactic acid bacteria BR 17 with strains of Lactobacillus fermentum CAU2036, Lactobacillus fermentum JCM 7772, and Lactobacillus fermentum 10-18. The identification results of lactic acid bacteria isolate BR 17 showed Lactobacillus fermentum BR 17.

Abstract

Polyunsaturated fatty acids (PUFA) supplementation in animal feed is expected to increase unsaturated fatty acids content in livestock products. Lemuru fish oil supplementation as a source of PUFA can function as a hydrogen sink to reduce methane production. The contribution of methane gas emissions in livestock reaches 15-17% of the world's methane gas emissions. Encapsulation of PUFA using natural ingredients of cinamaldehyde is expected to be a solution to increasing PUFA in livestock product and improving environmentally friendly animal husbandry. This study aimed to determine the effect of using cinnamaldehyde as an encapsulation agent for lemuru fish oil as a source of PUFA on in vitro gas, methane and CO2 productions. Treatments consisted of different levels of cinnamaldehyde, namely 0, 250, 500, 750 and 1000 (mg/kg feed DM), with the 5% lemuru oil as PUFA source. The experimental design used a one-way ANOVA in completely randomized design pattern consisting of five treatments and three replicates. Each replicate was duplicate, and then, if there were significant differences, it was continued with Duncan's New Multiple Range Test (DMRT) with SPSS version 23. This study discovered that the use of cinnamaldehyde did not affect the in vitro kinetics of gas and CO2 production. The use of cinnamaldehyde level of 500 mg/kg DM feed is the optimal level that can be used as an encapsulation agent for lemuru oil without causing an increase in methane production.

Abstract

Essential oil (EO), as a feed additive, is known to increase feed efficiency and reduce methane production in ruminants. This research was conducted to study the effect of Java cardamom (Amomum compactum Soland ex Maton) essential oil as a feed additive on ruminal feed fermentation. The in vitro gas production technique was used in this research to determine the effect of cardamom on nutrient digestibility or fermentation in the rumen. Cardamom meal was added into the feed sample to obtain final EO concentrations in the fermentation medium of 0, 25, 50, 75, and 100 mg/L. The substrate consisted of Pennisetum purpureum, rice bran, and wheat pollard. The addition of cardamom did not significantly affect dry matter digestibility, except at 100 mg/L, where it decreased. Protein digestibility decreased when the diet was supplemented with cardamom, whereas organic matter and crude fiber digestibility increased by up to 13.5% and 24% at the 100 mg/L EO level, respectively. The production of volatile fatty acids (acetate, propionate, butyrate), pH, and microbial protein synthesis, except ammonia concentration, were not affected by cardamom addition. Similarly, methane production and protozoa population did not significantly change. The utilization of Java cardamom as a feed additive positively affected ruminal fermentation by increasing organic matter and crude fiber digestibility, while reducing protein digestibility.
