Factor XI Deficiency (FXID) is caused by imperfect insertion of poly adenine which is resulted in introduction of premature stop codon in FXI gene. Substitution of guanine into thymine in SLC35A3 gene caused Complex Vertebral Malformation (CVM). The research was aimed to detect the presence or absence of a genetic defect mainly CVM using SLC35A3 gene and FXID using FXI gene in Indonesian Bali cattle. The presence of this genetic defect may have a significant economic impact on the breeding program. The research of genetic defect was done mostly in dairy cattle, but there was no report for screening of genetic defect in Bali cattle. In this study, 303 fresh blood samples and 22 semen samples which were collected from Indonesian Bali cattle breeding center (BPTU HMT Denpasar, BPT HMT Serading West Nusa Tenggara and district Barru South Sulawesi) and artificial insemination centre (BBIB Singosari and BIBD Baturiti) were used for screening of FXID and CVM. The amplicons of FXI gene were obtained by using PCR and that for SLC35A3 gene were obtained by using PCR-RFLP method with PstI restriction enzyme. These PCR products were analyzed by using 2% agarose gels electrophoresis. All genotypes were confirmed by DNA sequencing to determine an allele mutant. The allele mutant was not found in all of the samples. The result of this study showed that CVM and FXID were not detected in Bali cattle from Indonesian Bali cattle breeding and artificial insemination centres.Key words: Bali cattle, genetic defect, SLC35S3 gene, factor XI gene

The aims of this study were to screen and characterize lactic acid bacteria (LAB) isolated from gastrointestinal (GI) tract of Cemani chicken, one of Indonesian local chicken and to investigate their potential use as probiotics. LAB were isolated from GI tract using MRSA and GYPA media and incubated anaerobically. Selected LAB were determined their probiotic properties with several assays. Identification of selected LAB was based on 16S rDNA sequences, morphological and biochemical characteristics. Ninety five bacteria were isolated and characterized as lactic acid bacteria (Gram positive, catalase negative, non sporeforming and acid producing). Twenty four isolates of LAB demonstrated antimicrobial activity against Escherichia coli JCM 1649 and Salmonella enteritidis B2586, and three selected isolates, i.e. CCM011, CSP004, and CVM002 showed the highest inhibition activity. The isolates had characters of high cell surface hydrophobicity and inter-isolate coaggregation ability of LAB, high survival at low pH, high phytase and protease activity (but no amylase and lipase activity), weak coaggregation with pathogen and no resistance to the examined antibiotics. The isolates were identified based on sequence analysis of 16S rRNA gene as Lactobacillus salivarius, however, each isolate had different profiles of sugar fermentation. Therefore the three LAB isolates had potential application as probiotics for chicken.Key words: Cemani chicken, gastrointestinal tract, lactic acid bacteria, probiotic

Porang (Amorphophallus muelleri Blume) is an indigenous Indonesian plant containing high hemicellulose as a source of glucomannan. An alternative way to produce a good quality of mannooligosaccharides was through hydrolysis of glucomannan by endo-β mannnase from actynomicetes. Based on 16S rRNA analysis, BF 3.10 isolate, isolated from Bukit Duabelas National Park soil, Jambi was identified as Streptomyces violascens BF 3.10. Reducing sugar was analyzed by dinitrosalicylic acid methods. The highest reducing sugar was achieved at the 72 hours of incubation. Mannanase of isolate BF 3.10 had the highest activity at pH 6 and temperature of 70 °C with enzyme activity of 16.38 U/mL and was stable at 4 °C for 48 h. During 5-hour of hydrolysis with substrate concentration of 0.25%, 0.5%, and 1% porang glucomannan dissolved in 10 mL enzyme, mannooligosaccharides were produced with the degree of polymerization of 2-3. Visualization of the products by using thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) methods showed that mannooligosaccharides produced comprised of glucose, mannobiose, mannotriose, and mannotetraose. The degree of polymerization and the simple sugars produced indicated that mannanase produced by S. violascens actively catalyzed the hydrolysis of 1.4-β-D-mannoside linkage from β-1.4-mannan backbone, that eventually produced simple sugars of mannooligosaccharides.Key words: glucomannan, mannanase, mannooligosaccharides, porang, Streptomyces violascens

Buffalo’s rumen bacteria (BRB) are potential in digesting fiber feed. BRB already adapted well with low quality forages and agricultural byproducts. The aim of this study was to determine the effect of buffalo’s rumen bacteria (BRB) consortium inoculated into preweaning Frisian Holstein calves on nutrient digestibility, physiological status, mineral uptake, and blood profile. This study used 14 isolates of bacteria isolated from rumen fluid of four local buffalos. The research units consisted of seven Frisian Holstein calves at two weeks old with the average body weight of 43.6±4.5 kg. Calves were inoculated with 20 mL of buffalo’s rumen bacteria isolates [4.56 x 109 cfu/mL] every morning for 10 weeks. The calves were divided into two groups i.e., three calves received bacterial inoculation and four calves without any inoculation. The variables which were analyzed in the preweaning and weaning period were feed intake, digestibility, average daily gain (ADG), feed conversion ratio (FCR), rumen fermentation characteristics, body weight, physiological status, blood profile, and mineral status. Data were analyzed statistically using t-test. The results showed that inoculation of buffalo’s rumen bacteria into Frisian Holstein calves effectively increased feed intake, characteristics of leukocytes and neutrophils, and cobalt (Co) uptake during the weaning period. Inoculation of rumen bacteria improved rumen pH during preweaning and weaning periods. Inoculation of rumen bacteria also had no negative effects on digestibility, feed conversion (FCR), average daily gain (ADG), and physiological status.Key words: buffalo rumen bacteria, digestibility, physiological status, blood profile, Pennisetum purpureum

Liquid smoke is one of the feed additive that can be given to animals. The aim of the study was to determine the influence of liquid smoke given through drinking water on meat quality and production of fecal ammonia in broiler. Variables observed were meat pH, water holding capacity, cooking loss, the tensile strength of meat, cut off strength of meat, blood urea nitrogen and creatinine concentrations, and fecal ammonia. The experiment was assigned in a completely randomized design with 5 treatments, and 4 equal replicates. The treatments tested were symbolized as R0, R1, R2, R3, and R4, based on the level of liquid smoke added into drinking water (v/v) namely, 0%, 0.25%, 0.50%, 0.75%, and 1.00%, respectively. The data were subjected to analysis of variance, and continued to Duncan’s multiple range test to determine the difference between treatment mean values at 5% probability. The results indicated that addition of liquid smoke up to 1% did not affect the meat pH, water holding capacity, cooking loss, the tensile strength of meat, blood urea nitrogen, and creatinine content, but it decreased the cut off strength of meat and fecal ammonia. It was concluded that an optimal dose of granting liquid smoke through drinking water was 1%.Key words: liquid smoke, broiler, meat quality, fecal ammonia

This in vitro experiment was conducted to evaluate the ruminal performances of polyunsaturated fatty acid (PUFA)-diet (containing PUFA with 80% concentrate and 20% King grass) supplemented with yeast and C. xanthorrhiza Roxb. Experimental design was completely randomized block design of 4 x 4 with ruminal liquor derived from 4 slaughtered goats and 4 treatments (PD0-no supplement, PDY- 0.5% yeast, PDC-2% curcuma, and PDM- 0.5% yeast + 2% curcuma). Variables measured were pH, N-NH3, total and partial VFA (volatile fatty acid), protozoa population, and CH4 (methane). Results showed that the lowest (P<0.05) organic (59.63%) and dry matter (58.00%) digestibilities were found in PDM. In in vitro, this diet was also showing quantitatively low in N-NH3 (8.73 mM) and protozoa population (7.90±4.09 103 cfu/mL). On the other hand, it showed numerically high in VFA production (45.27 mM) and pH (6.74), yet low in CH4 (13.43% v/v). Based on these data, PDM was considered the most potential diet to improve nutrient metabolism in rumen of goat, in vitro.Key words: PUFA- diet, yeast, curcuma, in vitro fermentation

Impacts of Domestic Maize Price Changes on the Performance of Small-scale Broiler Farming in Indonesia S J K Umboh; D B Hakim; B M Sinaga; I K Kariyasa

Publisher : Faculty of Animal Science, Bogor Agricultural University

This research aimed at analyzing the impact of maize price changes on the performance of small-scale broiler farming in Indonesia using a multimarket model analysis. The multimarket model analysis is partial equilibrium analysis that contains six blocks of equations: prices, supply, input demand, consumption, income and equilibrium. This model analysis was originally designed in General Algebric Modelling System (GAMS) using the Path NLP solver. Employed data in this study were classified into 3 types, namely: (1) production and input, consumption, and household income; (2) inputs and outputs, and (3) elasticities. Decreased domestic maize price was responded by farmer through reducing maize planted area and fertilizers uses. It further had undesired impact on the maize production and maize farmer’s income. Whereas, this policy had positive impact on meat production and small-scale broiler farming income. The opposite impact will happen on those variables, if government increases domestic maize price. This policy caused the maize demand for feed industry decreased. As a result of this condition, it decreased the chicken meat production and small-scale broiler farming income.Key words: maize, broiler, price, multimarket

Prophylactic Modulation of Methane and Nitrous Oxide Emitted from Ruminants Livestock for Sustainable Animal Agriculture (REVIEW) J Takahashi
Media Peternakan Vol. 37 No. 3 (2014): Media Peternakan
Publisher : Faculty of Animal Science, Bogor Agricultural University

Major greenhouse gases (GHG) attributed to animal agriculture sector are methane (CH4) and nitrous oxide (N2O), either generated from enteric fermentation or manure. The abatement mechanism of rumen CH4 emission may be divided to direct and indirect suppression to methanogens in the rumen.The most significant strategy to mitigate ruminal CH4 emission in indirect manner is to promote alternative metabolic pathway to dispose of the reducing power, competing with methanogenesis for H2 uptake. This includes prebiotics and probiotics (mostly propionate enhancers) which consume metabolic hydrogen (H2) compete with methanogens and abate rumen methanogenesis in indirect manner. With regard to mitigate GHG emissions from manure, such waste has been proposed as a renewable energy and nitrogen sources through biogas plant. Furthermore, in advanced new biogas system, the ammonia stripping from digested slurry of livestock manure in biogas plant has been examined to apply to nitrogen recycling-options mitigating N2O emission. These options are: (1) ammonolysis on fiber-rich feedstuffs, (2) saccharification of the NH3 treated cellulose biomass to produce bio-ethanol, and (3) reformed hydrogen into NH3 fuel cell to generate electricity with proton exchange membrane fuel cell (PEM).Key words: rumen methane, nitrous oxide, probiotics, prebiotics, ammonia stripping
