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.

Abstract

The ADIPOQ and EDG1 genes were responsible in intramuscular fat deposition and marbling scores. This study was aimed to identify polymorphism of indel g.81966364D>I in promoter region of ADIPOQ gene and SNP c.-312A>G in 5' UTR of EDG1 gene in Indonesian beef cattle. Blood samples were collected from 211 cattle, including Bali (44), Madura (20), Pesisir (18), Katingan (20), PO (22), Pasundan (20), SO (12), Brahman (20), Simmental (15) and Limousin (18). Polymorphism of ADIPOQ gene was analyzed using PCR and direct sequencingmethods, whereas EDG1 gene was analyzed using PCR-RFLP (MscI enzyme) and direct sequencingmethods. Results of genotyping indel g.81966364D>I was monomorphic (DD genotype). The SNP c.-312A>G was polymorphic (AA and AG genotype) in Madura, Pesisir, Pasundan, Brahman, and Limousine. The Frequencies of allele A and G were 0.95, 0.92, 0.98, 0.95, 0.94 and 0.05, 0.08, 0.02, 0.05, 0.06 respectively. The values of Ho and He were 0.05-0.17 and 0.05-0.15 respectively and in Hardy-Weinberg equilibrium (P>0.05). In Bali, Katingan, PO, SO and Simmental were monomorphic (GG genotype). In Bali cattle, two novel SNP candidates were found in position of c.-399C>T and c.-273C>G which were potential to be used as genetic markers of marbling score for Bali cattle. As result this study, it can be concluded that ADIPOQ gene was similar while EDG1 gene was different in Indonesian beef cattle. in addition, found two candidates potential SNP in Bali cattle.

Abstract

An experiment imposing the multi continuous phase feeding was carried out to evaluate the EFG(Emman, Fisher and Gous) Growth Model in its capacity to predict amino acid requirements in broilers.Birds were fed using blended summit (247.91g/kg CP, 3200 kcal of ME /kg) and dilution (166.26 g/kgCP, 3200 kcal of ME g/kg ) diets and offered to 2-4 or 8 phases. Two hundred male day-old broilerchicks of two commercial strains (A=Ingham and B = Steggles) were used. The predicted responseswere greater than the observed both gain (g/d) and feed intake (g/d). The discrepancy between theobserved and predicted gain in the strain A and B birds, showed a different pattern, with a markeddifference during the early growing period, with a degree of convergence in the late growing period forthe strain A but the reverse picture for the strain B. This shows that strain characterization is notaccurate due to an inadequate definition of the genotypes by the model. Non agreement betweenpredicted and determined gain and feed intakes provided little benefit in moving towards a morefrequent change in diet to accommodate predicted growth-related changes in amino acid requirements.

Abstract

The study was conducted to evaluate forage productivity of arbila (Phaseolus lunatus) as theruminant feed at various levels of rhizobium inoculants and harvesting times, was designed followingcompletely randomized design of factorial pattern with two factors. The first factor was the level ofinoculums (I) i.e. I1 (without inoculum), I2 (5 g/kg seed), I3 (10 g/kg seed), and I4 (15 g/kg seed). Thesecond factor was harvesting time (U) i.e. U1 (60 days), U2 (80 days), U3 (100 days) with 4replications. The variables were N uptake, production of dry matter (DM) and organic matter (OM), andpercentage of OM, crude protein (CP), crude fiber (CF), nitrogen free extract (NFE), extract ether (EE)and ash of arbila forage (based on DM). The results showed that inoculant treatment at the rate of 15g/kg seed produced the highest percentage of effective nodules (98.72%), and in combination withharvesting age at 100 days each polybag of plant was able to absorb the higest amount of N (688. 10 g)with production of DM 273.81 g, OM production 263.96 g and nutrients content based on DM of about91.14% OM, 33.52% CF, 34.76%, 5.75% EE, 09.37% ash, and 16.16% CP. From the study, it can beconcluded that arbila plants inoculated specific rhizobium Phaseolus vulgaris at the rate of 15 g/kg seedand harvested at 100 days yielded the best forage as feed.

Abstract

The aim of this study was to investigate the association and expression of LEPR with fat quality, flavour and odour in sheep. A total of 47 rams were used in this study. Fatty acids composition, BCFA (Branch Chanin Fatty Acids; MNA, MP, MOA, and EOA) and skatole (MI) representing fat quality, flavour and odour in sheep were measured at ages of 10-12 months old. Identification of novel variant and expression analysis of LEPR gene with different fat quality, odour and flavour were performed by PCR RFLP and qRT-PCR, respectively. A SNP in genomic region g.40854778 A>C of the LEPR gene was associated (P<0.05) with fat quality of saturated fatty acids (SFA) including [tricosanoic acid (C23:0) and tetracosanoic acid (C24:0)] and poly unsaturated fatty acid (PUFA) [docosahexaenoic acid (C22:6n3)]. However, the novel variant of LEPR was not significantly associated (P<0.05) with fat content, odour and flavour (MNA, MP, MOA, EOA, and MI). The mRNA expression analysis showed that LEPR mRNA expression was higher (P<0.01) in sheep found at the AA genotype. It could be concluded that variant SNP in the LEPR may contribute to fatty acid composition without influencing odour and flavour traits in sheep.

Abstract

This research was conducted to study the influence of protected kapok seed oil (PKSO)supplementation in its combination with concentrate, in this case was rice bran (RB) on lipid content ofthin tailed sheep received field grass as basal feed. A number of 24 heads of male thin-tailed sheep wereused as experimental material. These sheep were divided into 8 treatment groups. There were twotreatment factors, i.e. : PKSO supplementation (S) as factor I and RB supplementation (K) as factor II.Factor I consisted of 2 levels, i.e. 0% (S0) and 10% (S1), whereas factor II consist of 4 levels, i.e. 0%(K0), 15% (K1), 30% (K2) and 45% (K3), respectively, based on dry matter (DM) intake. Severalvariables were measured, namely content of intra muscular fat (IMF), iodine number of muscular fattyacid, content of meat cholesterol and omega 6 fatty acid (in this case linoleic acid). The collected datawere statistically analyzed by analysis of variance with factorial treatment pattern (2 x 4) in completelyrandomized design (CRD). Content of IMF in sheep supplemented with 0 and 15% KSO levels was notsignificantly different from those without kapok seed oil (KSO) supplementation at the same level ofRB feeding (3.45 and 3.99% vs 3.01 and 3.75%). Supplementation of protected KSO in combinationwith 30 and 45% RP resulted in significantly increased (P < 0.05) IMF content (4.75 and 5.93% vs 4.32and 5.40%) and significantly decreased (P < 0.05) meat chollesterol content (62.46 and 65.26 mg/100 g vs 89.21 and 72.63 mg/100 g ) also significantly increased (P < 0.05) linoleic acid proportion (15.52 and18.25% vs 3.68 and 4.04%) and iodine number (12.52 and 10.25 vs 4.09 and 4.98).

Abstract

The objective of this research was to investigate the potential of snakehead albumin extract (channalbumin) for sorting X and Y sperm of Sumba Ongole (SO) and its characteristic. Semen was collected from three SO bulls using artificial vagina and the freeze dried channalbumin was extracted from snakehead fish. Channalbumin column was made with different concentration ratio of top and bottom fraction: 2%:4%; 3%:5%; 4%:6% respectively and BSA 5%:10% as control. Semen was put in top fraction then incubated for 30 min at room temperature then each fraction was centrifuged at 1800 rpm for 10 minutes. The pellet was evaluated for motility, abnormality, viability, membrane integrity and head sperm morphometric. The results showed that the channalbumin capable to maintain sperm motility in the top fraction better than the bottom fraction. Sperm viability and membrane integrity in control group were significantly higher (P<0.05) than all channalbumin treatment. BSA 5%:10% has highest proportion of X and Y sperm (69%:76.77%) compared with 2%:4% (42.33%:79.13%), 3%:5% (55.97%:75.73%) and 4%:6% of channalbumin (62.77%:68%). It’s concluded that channalbumin 4%: 6% was effective for separation of XY sperm with higher proportion.
