           Ettawa Grade goats

    • Authors: D. A. Lestari, S. Sutopo, E. Kurnianto
      Pages: 135 - 146
      Abstract: The objectives of study were to identify and assess the amino acid diversity of Cytochrome b (Cyt b) gene, genetic marker and characteristic of specific amino acid in Kacang and Ettawa Grade goat. Nineteen heads of Kacang goat (KG) and twelve heads of Ettawa Grade goat (EG) were purposively sampled. The genomic DNA was isolated by Genomic DNA Mini Kit (Geneaid) and amplified Cyt b using PCR method with CytbCapF and CytbCapR primers and was sequenced. The results showed that there were two specific amino acids that distinguish KG and EG goat with C. hircus and C. aegagrus and four specific amino acids that distinguish KG and EG goat with C. falconeri, but there were no specific amino acids can be used as a genetic marker to distinguish between Kacang and EG goat. In conclusion, specific amino acids in Cyt b gene can be used as a genetic marker among KG and EG goat with 3 goat others comparator.

  • Association of growth hormone (GH) gene polymorphism with growth and
           carcass in Sumba Ongole (SO) cattle

    • Authors: P. P. Agung, S. Anwar, W. P. B. Putra, M. S. A. Zein, A. S. Wulandari, S. Said, A. Sudiro
      Pages: 153 - 159
      Abstract: A study was conducted to identify the polymorphism in the intron 3 of the Growth Hormone (GH) gene and also to evaluate the association of the GH gene polymorphism with growth parameters and dressing percentage in the Sumba Ongole (SO) cattle. A total of 267 individual DNA samples were used in the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) analysis. The SO cattle growth parameters data (n=44) including birth weight (BW), weaning weight at 205 days of age (WW205), yearling weight at 365 days of age (YW365) and also dressing percentage (DP) (n=122) were investigated in this study. There were three genotypes (AA, AB, and BB) of the GH gene based on the PCR-RFLP analysis with allele frequency was 0.87 and 0.13 for A allele and B allele respectively. The highest genotype frequency in the SO cattle is AA (0.76) and the lowest is BB (0.02). The Heterozygosity Observed (Ho) value in the SO cattle population is 0.23 and Polymorphism Information Content (PIC) value is 0.20. Therefore, the genetic diversity in the SO cattle based on the GH gene polymorphism is quite low. There is no association (P>0.05) in BW, WW205, YW365, and DP with genotypes of the GH gene. As the result, the GH gene in this study cannot be used as a genetic marker in the SO cattle breeding program.

    • Authors: S. Sumadi, A. Fathoni, D. Maharani, N. Ngadiyono, D. T. Widayati, C. T. Noviandi, M. Khusnudin
      Pages: 160 - 166
      Abstract: The objective of study was to estimate breeding value of sires of Kebumen Ongole grade cattle based on offsprings weaning weight. This research was carried out from August to December 2015 in Urut Sewu area, Kebumen. The calculation of genetic parameter estimation was heritability of weaning weight. The value of heritability was used to calculate the breeding value of sires based on offsprings weaning weight. Heritability was calculated using paternal half-sib correlation with the direct pattern variance analysis. Breeding Value (BV) of sire was calculated by absolute estimated breeding value. The materials used in this study included were data record during the last three years (2013-2015) consisted of 41 sires, 51 dams and 244 calves. Weaning weight data had been corrected based on age of dams, sex and weaning age of 120 days. The results showed that the heritability value of weaning weight was included in high category (0.36 ± 0.21). The highest BV was KJ.J608 (49.76) with a ratio of 231.45%. The results of this study were expected to be the basis recommendation for selecting sires in Kebumen.

           growth hormone gene in muscovy duck

    • Authors: I. Ismoyowati, E. Tugiyanti, M. Mufti, D. Purwantini
      Pages: 167 - 174
      Abstract: This research was aimed to investigate the different growth and to identify growth hormone gene polymorphism in Muscovy ducks. Two hundred Muscovy day-old ducks consisting of white-plumed male and female duck, black and white-plumed male and female ducks. Body weight was recorded weekly and the obtained data were subject to T test. Primer design used the Custal X Program based on a database from the GeneBank Cairina moschata GH gene, partial cds (AB158762). Primer base sequence of GH gene was forward/Sequence: 5’-CTGGGGTTGTTTAGCTTGGA-3’ and reverse/Sequence: 5’-TAAACCTTCCCTGGCACAAC-3’. The DNA sequences were aligned by using the BioEdit version 7.7 for identification of the single nucleotide polymorphism. The result showed that male Muscovy duck produced higher an average body weight gain and more relative growth than those of females. The highest body weight gain was at three weeks old, and then it started to decrease at four weeks old. The sequencing PCR product obtained nucleotide polymorphism. AA genotype was observed at 136 t of black female Muscovy duck, CC in black and white male Muscovy duck, and white female Muscovy duck. Conclusively, a body weight gain of 3-week-old male Muscovy ducks was higher than that of females and GH gene polymorphism was observed in Muscovy ducks.

      Pages: 175 - 184
      Abstract: The g.422C>T nucleotide variations in the 5’ untranslated region (5’UTR) of TG gene (called as TG5) has been reported to be associated with level in intramuscular fat (IMF) content or marbling in beef cattle. The objective of this study was to confirm genetic polymorphism of TG5 gene in Bali cattle populations from three different regions as the main resources of Bali cattle in Indonesia. A total of 200 head of Bali cattle have been performed genotyping on TG5 gene using polymerase chain reaction-restriction fragment lenght polymorphism (PCR-RFLP) method and sequence analysis. Results of the study confirmed that TG5 was monomorphic in Bali cattle wherever their origin regions. Moreover, nine candidate SNPs were detected within 5’UTR of TG gene in Bali cattle compared to Genbank reference sequences, although no SNP variations among Bali cattle sample studied. The new other genetic markers within an entire TG gene suggested to be explored and verified for their polymorphisms in Bali cattle. The nine candidate SNPs were also required further verification and validation in a larger sample to be regarded as new SNPs between Bali cattle and Genbank reference sequences.

    • Authors: L. Khotijah, E. I. Pandiangan, D. A. Astuti, K. G. Wiryawan
      Pages: 185 - 193
      Abstract: The study was aimed to evaluate the increasing levels of ration energy, with fat-rich unsaturated fatty acids from sunflower oil on the nutrient intake, rumen fermentability and performance of ewes. The experiment used fifteen ewes of 1.5 years old, primiparous, caged individually with their lambs and conducted three treatments and five replications from a completely randomized designed. Those treatments included R1= ration with 0% sunflower oil addition, R2= ration with 4%sunflower oil addition, R3= ration with 6% sunflower oil addition. The variables consisted of dry matter intake, nutrients, ewes performances (birth weight, weaning weight, decreased of body weight), total and partial VFA, the ratio of acetate: propionate, methane production, protozoa and bacterial population. Data were analyzed statistically and descriptively. The results showed that the treatments did not influence dry matter intake and nutrients,. rumen fermentability and ewes performances. Although the treatments increased (P<0.01) fatconsumption and reduced shrinkage of body weight. It can be concluded that the adding sunflower oil as the resource of unsaturated fatty acids up to 6% of the ration was not negatively affected the fermentability of rumen, moreover can improve ewes body condition and, accelerated body weight recovery

    • Authors: N.M.J. Arini, S. Sumiati, R. Mutia
      Pages: 194 - 201
      Abstract: The objective of this study was to evaluate the effectiveness usage of Indigofera zollingeriana leaf meal (I) and Sardinella lemuru fish oil (L) in diets on the decreasing levels of cholesterol and lipid metabolism of laying duck. One hundred and forty-four Magelang ducks aged 20-32 weeks, laying periode, with an average body weigth of 1,72±0,12 kg were used, which were divided into 6 groups of experimental diets, 3 replications, and of 8 layers each. A completely randomized design, 3x2 factorial design was used in this experiment. The first factor was usage Indigofera zollingeriana leaf meal which replaced protein soybean meal (0%, 5,5%, 11%). The second factor was usage Sardinella lemuru fish oil (0%, 2%). The results showed that the treatment (I5.5L2) was highly significant affected (P<0.01) the level of triglyceride, HDL, and LDL in the blood. The treatment I0L2 significantly decrease (P<0.05) total cholesterol of blood lipid profile and meat cholesterol. The treatment (I11L2) was highly significantly decreased (P<0.01) egg cholesterol. The conclusion of this study was that feeding Indigofera zollingeriana leaf meal 5.5% and Sardinella lemuru fish oil 2% in laying duck’s diet could maintain the balance of blood lipid profiles by lowering plasma triglycerides, LDL, cholesterol and raising up plasma HDL and plays an important role on lipid metabolism of Magelang laying ducks to produce eggs and meat with low cholesterol content.

  • The use of coconut pulp as a feed substrate to methanogenesis inhibitor in
           in vitro rumen fluid fermentation

    • Authors: E.H.B. Sondakh, J.A.D. Kalele, F.S. Ratulangi
      Pages: 202 - 209
      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.
