Abstract

A study of genetic variation of four blood protein loci and three egg white loci in three breeds ofIndonesian local ducks (Magelang duck = MAD, Tegal duck = TED and Mojosari duck= MOD) wasinvestigated by using polyacrilamide gel electrophoresis (PAGE). The result showed that four bloodprotein loci (Pre-albumin, Albumin, Transferrin and Post-transferrin) and three egg white loci(Ovalbumin, Ovoglobulin and Conalbumin) were found to be polymorphic in three breeds of localducks. There was no difference on blood and egg white protein polyimorphism. The average value ofheterozygosity on three breeds of local ducks had a genetic potential to determine the controlled matingsystem and selection to obtain pure line. The closest phylogenetic relationship among the three breeds oflocal ducks occurred between MAD and TED.

Abstract

A field experiment was conducted on Chromolaena odorata dominated pasture with the objectivesof evaluating efficacy of integrated of mechanical and cultural control on weed suppression anddetermining botanical composition of plant species after treatment started. The treatments were, T1slashing of Chromolaena every month, T2 digging up of Chromolanea, and exposed to dry (mulching),T3 digging up of Chromolaena followed by burning, T4 digging up of Chromolaena followed byburning and sowing with Centrosema pubescens and T5 digging up of Chromolaena followed byburning and planting with Brachiaria decumbens. Results of experiment showed that under droughtconditions, digging up Chromolaena was very effective in suppressing regrowth of Chromolaena but itwas not effective to other weeds. Among treatments, digging out of Chromolaena followed by burningand planting with Brachiaria decumbens was the most effective and slashing of Chromolaena everymonth was the least effective in suppressing weeds. Botanical composition was shifted with treatments.Stachytarpheta jamaicensis and Chromolaena were the dominant species in monthly slashedChromolaena plots, Stachytarpheta and Calopogonium muconoides were the dominant species inmulched plots while Mimosa pudica, Brachiaria and Centrosema were the dominant species in burntplots.

Abstract

The experiment was conducted to investigate the angiotensin converting enzyme (ACE) inhibitoryactivity of hydrolysate in meat protein of Bali cattle, Kacang goat, native chicken, and local duck. Themeats of Bali cattle, Kacang goat, native chicken, and local duck were used in this study. The meatswere ground using food processor added with aquadest to obtain meat extract. The meat extracts werethen hydrolyzed using protease enzymes to obtain hydrolysate of meat protein. Protein concentration ofmeat extract and hydrolysate of meat protein were determined, and were confirmed by sodium dodecylsulfate - poly acrylamide gel electrophoresis (SDS-PAGE). ACE inhibitory activity of hydrolysate ofmeat protein derived from Bali cattle, Kacang goat, native chicken, and local duck was also determined.The results showed that protein concentration of hydrolysate of meat protein of Bali cattle, Kacang goat,native chicken, and local duck meat was significantly higher than their meat extracts. SDS-PAGEanalysis indicated that hydrolysate of meat protein of Bali cattle, Kacang goat, native chicken, and localduck had more peptides with lower molecular weight, compared to their meat extracts. Hydrolysate ofmeat protein of Bali cattle, Kacang goat, native chicken, and local duck had potencies in inhibiting ACEactivity, so it will potentially reduce blood pressure.

Abstract

The research was conducted to evaluate the effect of mulch and mixed cropping grass – legume atsaline soil on growth, forage yield and nutritional quality of guinea grass. Saline soil used in thisresearch was classified into strongly saline soil with low soil fertility. The research was arrranged inrandomized complete block design with 3 blocks. The treatments were : M1 = guinea grassmonoculture, without mulch; M2 = guinea grass monoculture, 3 ton/ha mulch; M3 = guinea grassmonoculture, 6 ton/ha mulch, M4 = mixed cropping grass with Sesbania grandiflora, without mulch;M5 = mixed cropping grass with Sesbania grandiflora, 3 ton/ha mulch; M6 = mixed cropping grass withSesbania grandiflora, 6 ton/ha mulch. Data were analyzed using analysis of variance, then followed byDuncan's Multiple Range Test. The highest soil moisture content was achieved at mixed cropping grasslegumewith 6 ton/ha of mulch. The effect of mulch at saline soil significantly increased plant growth,forage yield and nutritional quality of guinea grass. Application of 3 ton/ha mulch increased plantgrowth, forage yield and nutritional quality of guinea grass. Plant growth, forage yield and nutritionalquality of guinea grass were not affected by monoculture or mixed cropping with Sesbania at saline soil.

Abstract

Antibacterial properties of three medicinal plants used widely amongst the native Indonesians, i.e.,sirih (Piper betel), garlic (Allium sativum) and jinten hitam (Nigella sativa) were screened and evaluatedagainst Salmonella sp. isolates. For this purpose, the three plants’ powder, aqueous and ethanol extractswere prepared. The tests’ results demonstrated the three plants’ anti Salmonella sp. activities. In thisconjunction, the aqueous extract of Allium sativum, the ethanol extracts of Nigella sativa, and Piperbetel, consecutively produced 17 mm, 15 mm and 13 mm diameter of bacterial growth inhibition zones.As a comparison, sensitivity tests of three commercial antibiotics, i.e., chloramphenicol, tetracycline,and gentamycin on Salmonella sp. isolates produced 19.7-27.3 mm growth inhibition zones. Garlichaving antimicrobial potential was comparable to the commercial antibiotics, can be used as adecontaminant against Salmonella sp. to maintain the quality of the broiler carcasses and thereforeprolonging the carcass shelf-life.

Abstract

This study was aimed to develop nanoparticle formulation using turmeric extract and industrialchitosan as the polymer and sodium-tripolyphosphate as cross linker, to evaluate its ability to improvetrue metabolizable energy on broiler chicken. Forty eight of broiler chickens with an average bodyweight of 900 g, were randomly divided into 8 treatments (one treatment was fasted and 7 were fedration plus feed additive), containing six birds per treatment. The formulation of nanoparticle in thisstudy used ionic gelation method. Method used to evaluate the metabolizable energy was totalcollection. Chickens were fasted one day before and after they were treated with rations. Nitrogen, grossenergy and total weight of feed and excreta or ileal digesta released were analyzed to calculate the truemetabolizable energy of the ration. It was found that the basal ration added with nanocapsule 0.1% hadtrue metabolizable energy (3370.66 kcal/kg) significantly higher (P<0.05) than basal ration (3214.85kcal/kg). The result of this study concluded that formulation of nanocapsule using turmeric extract andindustrial chitosan as the polymer and sodium-tripolyphosphate as cross linker was potential to increasetrue metabolizable energy so it can be an alternative for broiler chicken feed additive.

Abstract

The aim of this study was to investigate the different of plumage colors on morphological diversityof Magelang duck and genetic diversity using PCR-RFLP mtDNA D-loop region analysis of Magelangduck and four others native duck population (Tegal, Mojosari, Bali and Alabio duck) in Indonesia. Bloodsample was taken from 50 Magelang ducks and 20 of each native ducks. Morphological characteristicsof body measurement, production ability and egg quality of Magelang duck were analyzed usingCompletely Randomized Design with 11 plumage colors as treatments. PCR technique was administeredto amplify fragments in mtDNA D-loop region and PCR products were digested with endonucleaserestriction enzyme AluI and HaeIII. The result showed that morphology diversity of Magelang duck wasstatistically affected by different plumage colors. PCR-RFLP analysis using AluI and HaeIII restrictionenzyme resulted in six combinations of restriction fragment pattern shown in six haplotypes (A, B, C, D,E and F). Haplotype difference showed genetic diversity in the population of Magelang duck and theother native ducks. In conclusion, the different plumage colors affected morphology diversity ofMagelang duck. Genetic diversity of Indonesian native duck population could be identified by usingPCR-RFLP analysis on mtDNA D-loop region.

Abstract

This experiment was conducted to evaluate the effect of extract of plants containing tannin on invitro CH4 production, fermentation characteristics and nutrient degradability. Six of plant leaves i.e.Gliricidia sepium, Acacia mangium, Leucaena leucocephala, Desmodium intortum, Camellia sinensis,Calliandra calothyrsus and seed of Areca catechu were extracted by using water. Experimentaltreatments consisted of P. purpureophoides (300±5 mg) incubated alone or added with 1.2 mL of plantextracts. The in vitro neutral detergent fibre (NDF) degradability was determined using the first stagetechnique of Tilley and Terry. The results showed that total tannin concentration of plant extract rangedfrom 34 to 95 g/kg DM, and was lowest in D. intortum and highest in A. mangium. Methane productionwas significantly (P<0.001) lower with addition of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus extracts compared to control. Total tannin had a close relationship with CH4production (r=-0.79). There was strong correlation between CH4 production and NDF degradability(r=0.61). It was concluded that water extracts of A. mangium, L. leucocephala, A. catechu, C. sinensisand C. calothyrsus have potential to be used as rumen manipulator in order to reduce CH4 production inruminants.

Abstract

The objectives of this study were to identify the productivity and genetic diversity of local cattle inCiamis West Java based on DNA microsatellite, in order to provide the basic information for its rearing,conservation and development. Eighteen of local cattle were kept for 58 days by feeding concentratesand rice straw. The measured parameters were weekly body weight as well as carcass percentage. Thepercentage of comparing carcass was taken from PO, Bali and crossbred cattle from local cattle withLimousin, Simmental, Brahman and Angus cattle. Data were analyzed using Excel software and SAS(2004). Blood samples were taken from two subpopulations i.e., 46 and 52 samples from Tambaksariand Cijulang areas, respectively. Other DNA samples were collected from Bali, PO, Limousin, Simental,Brahman and Angus cattle. Genetic diversity and phylogenetic analysis were analyzed using 3microsatellite loci, that were INRA35, HEL9 and BM2113. The genotyping data were analyzed usingPOPGENE.32 program, while phylogenetic trees were analyzed by MEGA 4. Average daily gain (ADG)of local cattle in Ciamis was 0.62±0.23 kg/head/day with a carcass percentage was 51.62±1.80%. Thecarcasses percentage of local cattle in Ciamis was not significantly different from those of Bali, PO, andcrossbred cattle. The genetic diversity of local cattle in Ciamis was categorized in the medium level, thediversity of local cattle in Tambaksari subpopulation was higher than in Cijulang subpopulation. Localcattle in Ciamis had a closer genetic distance with the PO cattle.
