Abstract

This study evaluated lysine supplementation of 4 to 42 day of age of two commercial broilergenotypes (Arbor Acres and Lohmann). Four hundred and fifty day-old chicks were sexed andrandomly distributed into 60 bamboo pens each 2 m2. A starter commercial diet as a basal diet wassupplemented with lysine mono-HCL in a 2x2x5 factorial arrangement with lysine levels of 0.0, 0.5,1.0, 1.5 and 2.0 g/kg fed from 4-21 days of age, and then followed by a finisher diet fed from 22-42days of age. Feed consumption, body weight gain and FCR were determined on weekly basis. On d 43of experiment, 4 birds per each replicate were processed for carcass parameters. Results of the studyrevealed that lysine supplementation in a starter commercial diet increased significantly carcass weight(P<0.05. Improved breast meat and lower abdominal fat were found in lysine supplementation. ArborAcres broilers response more efficient in low lysine whilst Lohmann broilers were better in a higherlevel of lysine.

Abstract

This study aimed to explore the socio-economic benefits of Jabres cattle as potential local livestock in two agro ecological zones, lowlands and middle zone in Bantarkawung Sub-District, Brebes, Central Java. The data were collected by Participatory Rural Appraisal (PRA) method, which is an approach to families or individuals to analyze the reality of their living conditions. This study involved 60 farmers which selected by purposive sampling based on three considerations. The analytical model used to test differences is the analysis of independent T-test. The result showed that the farmers in the middle zone are younger and most of their cattle keeping motivation are for livelihood. Meanwhile, the farmers in the low lands are older and most of their cattle keeping motivation is for saving only (2.90±0.31). This condition caused the socio-economic benefit difference between those locations where the value of net production (185±27 kg/y), added value (IDR 4.900.000±1.204.000), and total benefits (IDR 9.289.000±1.542.000) were higher in the medium land than in the lowlands. Based on these reasons, it can be concluded that middle zone farmers have more possibility to sustain their farm than those of lowlands farmers.

Abstract

The objective of this study was to apply urea treatment of rice straw at elevated temperature and pressure (121oC; 1.4 atm) and at short treatment period (30 or 60 min) in comparison to conventional urea treatment (4 weeks incubation). Rice straw was subjected to the following treatments: RS1: untreated rice straw (control), RS2: RS1+1% urea (no incubation), RS3:RS1+1% urea (4 weeks incubation), RS4: RS2+autoclave 30 min, RS5: RS3+autoclave 30 min, RS6: RS2+autoclave 60 min, RS7: RS3+autoclave 60 min. The samples were analyzed for fiber contents and incubated in vitro. Data were analyzed using analysis of variance and Duncan’s post-hoc test. Results showed that urea treatments (RS3-RS7) did not change NDF and ADF contents of rice straw in comparison to control. Urea treatment in autoclave for 30 min (RS4) increased rice straw IVDMD and IVOMD by 23.3% and 25.6% as compared to control, respectively (P<0.05). Extension of the incubation period to 60 min (RS6) did not improve further the IVDMD and IVOMD. Treatments did not change pH values and NH3 concentrations. Urea treatment (RS3-RS7) increased total VFA concentration in comparison to control (P<0.05). It was concluded that urea treatment using autoclave for 30 min may replace conventional urea treatment to improve nutritional value of rice straw.

Abstract

The study was conducted to investigate the degradation of dry matter (DM) and neutral detergentfiber (NDF) of urea untreated (URS) and urea treated rice straw (TRS) incubated in the rumen of sheepfed different diet. Three fistulated sheep were fed on urea-treated rice straw basal diet with threesupplemental treatment diets which consisted of control diet (T0) mulberry and molasses; mulberry,rice bran and urea (T1); and rice bran and urea (T2). Either URS or TRS was placed in nylon bags andincubated in the rumen at 0, 8, 16, 24, 48 and 72 hours. Parameters recorded were degradation of DMand NDF, rumen pH, rumen ammonia. The results showed that DM degradability of URS of the diet T1was significantly lower than other diets. Similarly the URS degradability of rumen-insoluble fraction(b) of DM and NDF of T1 diet was significantly lower than those of T0 and T2 diet. DM and NDFdegradability of URS was not affected by diets. The rumen ammonia concentration of T1 and T2 wassignificantly higher than those T0, but still higher than critical ammonia concentration required forrumen microbial synthesis. These results suggest that different supplementations have no significanteffect on DM and NDF degradability of TRS.

Abstract

This study aimed to investigate the diversity of the complete sequence of D-loop mitochondrial DNA (mtDNA) in Bali and Sumba Ongole (SO) cattlebreeds. A total of 24 blood samples were collected from Bali cattle (19 heads) and SO cattle (5 heads), and were extracted and then analyzed to obtain the sequence of D-loop mt DNA.Multiple alignments of the whole sequence of D-loop mtDNA were determined using clustal W. Genetic distance was calculated using a p-distance method, while the genetic tree was constructed using neighbor-joining (NJ) based on MEGA 6. Haplotype number, haplotype diversity (Hd) and nucleotide diversity (Pi) were analyzed using DnaSP version 6. As a result, the sequence of D-loop mtDNA in Bali cattle (921-1119 bp) and SO cattle (913 bp) was reported to have 8 and 4 haplotypes. Hd and Pi of Bali cattle reached 0.625±0.139 and 0.0266±0.0145, respectively, which wwere different from that of SO cattle, namely 0.900±0.1610 and 0.0064±0.0015, respectively. Specifically, we found 22 bp-repetitive nucleotide in Bali cattle, existing 3-9 times with a length of 66-198 bp present in D-loop mtDNA. This unique feature did not exist in SO cattle. Genetic distance and genetic tree determined according to sequence in hypervariability (HV-1) region of D-loop mtDNA (166 bp) resulted in satisfied separation, successfully classifying Bos javanicus, Bos indicus, and Bos taurus cluster.

Abstract

This experiment was conducted to determine the effect of the adding of coconut pulp in ruminant feed on methane reduction in vitro. Rumen fluid and substrate of forage and concentrate in ratio 60:40 were in this study. This experiment consisted of five treatments of coconut pulp as followed: R1: feed substrates without the coconut pulp; R2: substrate feed with coconut pulp 5%; R3: substrate feed with coconut pulp 10%; R4: Substrate feed with coconut pulp 15% and R5: substrate feed with coconut pulp 20%. Each treatment was conducted to four replications. Fermentation was done using the Hohenheim Gas Test (HGT) incubated at 39oC for 72 hours. At the end of fermentation was determined production of methane, parameters of fermentation, microbial activity, feed digestibility and fatty acids profile of the ruminal fluid. Data obtained were analyzed by using analysis of variance using completely randomized design. The differences of mean values were analyzed by Duncan multiple range test (DMRT). The results showed that methane production has decreased about 13.74%-17.39% when the feed was given coconut dregs 15-20%. Based on the results of the study was concluded that the supplementation of coconut pulp up to 15-20% of 100% dry matter can be used as a substrate of ruminant feed, because it can reduce methane and does not interfere the microbial activity in the fermentation of rumen fluid through in vitro. The supplementation of coconut pulp can be a referencein designing the methanogenic inhibitor feed.

Abstract

Lipoprotein lipase (LPL) is a key enzyme that plays in metabolism and transport lipoprotein andtherefore has an influence on blood triglyceride levels. LPL controls triacylglycerol partitioning betweenadipose tissue and muscle that increases fat storage or provides energy in the form of fatty acids formuscle growth. The research was aimed to explore Single Nucleotide Polymorphisms of LPL gene andto associate SNP with marbling quality. A total of 66 genomic DNAs consisted of sumatera thin-tail edsheep (50 heads) and garut sheep (16 heads) were used in this study. Polymerase Chain Reaction wasused to amplify genomic DNA and direct sequencing method was to identify polymorphism sequences.The sequences were analyzed with Bio Edit and MEGA 5.2. The BLAST sequence was obtained fromgene bank X.68308.1. The association between the genotype and marbling quality was analyze by oneway ANOVA and further between mean differences were tested using least sgnificant difference. Theresults showed that 3 novel SNPs i.e. insertion g.26>C; insertion g.27> G and c.192T>C on garut sheepand a SNP insertion g.26>C/G on sumatera thin-tail ed sheep. The diversity of LPL gene at c.192T>Cwas associated with heneicosanoic acid, whereas TT genotype (0.04%) was higher than CC (0.03%) andCT (0.02%).

Abstract

Free radical levels can be higher than the level of endogenous antioxidants in the body so thatuncomfortable conditions in the body of dairy goats could happen. To anticipate this uncomfortableconditions will be given feed supplement (FS) as source of antioxidants (AOX). FS contain mixturepineapple rind meal and antioxidant minerals (AOXM) each 25 ppm Zn and 10 ppm Cu. Thisexperiment was carried out to investigate the effect of feed supplements as antioxidant source on milkquality of dairy goats. Sixteen Etawah dairy goats in the second lactation were used in the experimentthat conducted using randomized block design with 4 treatments and 4 replicates. The treatments wereR0 (grass + concentrate), R1 (R0 + FS containing 0.04 % AOX), R2 (R0 + FS containing 0.06% AOX),R3 (R0 + FS containing 0.08 % AOX). The data collected were analyzed using Anova. The result ofphytochemicals analysis indicated that feed supplement contained flavonoid, polyphenols, sesqiuterpen,mopnoterpen, steroids, quinones and saponins. The results of study showed that there were difference(p<0.05) among treatments on blood and milk cholesterol and milk lactose, but there were no difference(P>0.05) on milk yield, milk fat, milk protein and milk antioxidant. The conclusion of this study was thefeed supplements containing 0.08 AOX produced the best response to milk quality of dairy goats.

Abstract

The objective of this study was to evaluate the level of organic minerals and total mixed fiber ammoniation (TMFA) as basal feed on the performance of beef cattle. This study used the In Vivo technique and the experimental method using t-test. The t-test compares the best supplementation result on in vitro research and control treatment, each treatment got6 replications. The treatments tested were P1: 60% TMF ammoniation + 15% swamp legume without supplementation of organic minerals P2: 60% TMF ammoniation + 1.5 x Organic macrominerals (Ca, P, and S) NRC (2000) + 15% Swamp Legumes. The parameters measured in the in-vivo technique were nutrient digestibility consisting of dry and organic matters, crude protein, crude fiber, NDF, and ADF. The animal performance: ration and dry matter consumption, body weight gain and ration efficiency. The results showed that supplementation of minerals in rations with TMFA as basal feed had a significant effect (P<0.05) on nutrient digestibility (dry matter, organic matter, crude fiber, NDF, and ADF) and animal performance. The conclusion of this study was supplementation of organic macrominerals 1.5 x (Ca, P, and S) NRC (2000) in a ration with TMF ammoniation as basal feed can improve the beef cattle performance.
