  • Genetic polymorphism of kappa-casein gene in Friesian Holstein: a basic
           selection of dairy cattle superiority

    • Authors: S. D. Volkandari, I. Indriawati, E. T. Margawati
      Pages: 213 - 219
      Abstract: Caseins are milk protein subdivided into four main groups which are αS1, αS2, β-casein and kappa-casein (CSN3). Kappa-casein gene influences the manufacturing of milk properties. The aim of this study was to identify the kappa-casein gene polymorphism in Friesian Holstein (FH) cattle. Fifty nine (59) samples consisted of 32 (Malang), 10 (Sukahati Bogor) and 17 (Research Center for Biotechnology-Indonesian Institute of Sciences’s collections)were applied in this study. DNA samples were extracted by high concentrated NaCl and quantified by spectrophotometer. The kappa-casein gene was amplified at 379 bp fragment by PCR method using a pair primer of kappa-casein at 56oC annealing for 30 cycles. PCR-RFLP technique with HindIII was used for genotyping analysis. The result showed that there were three variants of genotypes (AA, AB and BB) in two populations from Malang and RC for Biotechnology-LIPI’s collection while cattle from Sukahati had only AA and AB genotypes. The averages of genotype frequencies were 65.28%; 65.28%; and 3.00% for AA, AB and BB genotypes respectively while frequencies of 0.81 and 0.19 were for A and B alleles, respectively. FH cattle populations were in equilibrium genetics. This finding concludes that polymorphism was found in three of FH populations with A allele was more common in kappa-casein locus. B allele is known having association with milk production, milk component and cheese yield. Increasing of B allele would influence on milk performance of FH cattle. Explorations of quantitative, qualitative and molecular genetics are important to improve dairy cattle performance.

  • Identification of BMP15 Exon 2 for fecundity traits by PCR-RFLP and
           nucleotide sequencies in Kejobong goat

    • Authors: A. Febriana, S. Sutopo, E. Kurnianto
      Pages: 220 - 226
      Abstract: Kejobong goat is known as prolific and high productivity goat breed in Indonesia. PCR-RFLP and sequencing technique was established in the present study to accomplish the polymorphisms of Bone Morphogenetic Protein 15 (BMP15) gene exon 2 on Kejobong goat does. The blood samples was collected from 48 Kejobong does which were selected based on their litter size. The size of PCR amplification of BMP15 gene exon 2 was 837 bp. The product of PCR-RFLP technique digested by HinfI enzyme showed that the samples were monomorphic. Authentication result using nucleotide sequencing found 4 substitution (A391G, C464G, T828C and C830G), 1 alignment gap (site 817) and 1 insertion nucleotide (site 822). This mutations caused 6 haplotypes formatted. The mutants of BMP15 exon 2 on Kejobong goats indicated that this breed had their own mutation controling the prolific trait. The phylogenetic tree build on the sequences of BMP15 gene exon 2 of Kejobong goats was grouped into 3 clusters. The alignment gap indicated to be the specific marker for the prolific trait (duplet) in Kejobong goat. The particular insertion site could be the recognition site of Kejobong goat based on BMP15 exon 2.

    • Authors: D. Samsudewa, S. S. Capitan, C. C; Sevilla, R. S. A. Vega, P. P. Ocampo
      Pages: 227 - 232
      Abstract: The aim of this research was to observe body (neck, chest and scrotum) circumferences and testosterone level of α-male, β-male and subordinate male Timor deer reared under captivity after establisment of the dominance hierarchy. Twelve males (51 ± 6 months old; 68.29 ± 8.41 kg body weight and in same antler stages) were used in this research. The bucks was grouped into three stall each containing four bucks. ELISA kit and tape measurements were used for plasma Testosterone assay and body measurement, respectively. Data was collected before and 43 days after establishment of the dominance hierarchy. Wilcoxon signed ranks test and Kruskal-Wallis H test of non-parametric analysis was used. Significant difference was tested with Mann-Whitney U test. The results showed no significantly different for body circumferences (neck, chest, scrotum) and testosterone level of male Timor deer before establishment of dominance hierarchy. Chest and scrotum circumferences of male Timor deer after establihment of dominance hierarchy showed no significantly different. Significantly difference shown on parameter neck circumference (P<0.05; χ2 = 8.74) and testosteron level (P<0.05; χ2 = 7.87) after establishment of dominance hierarchy. In conclusion, dominance hierarchy affected the testosterone level and body measurement.

           nonlinear mathematical model in Kebumen Farmer Association

    • Authors: D. Maharani, A. H. K. Amrullah, D. T. Widayati, S. Sumadi, A. Fathoni, M. Khusnudin
      Pages: 233 - 239
      Abstract: This research is aimed to evaluate the nonlinear mathematical model in predicting the age and weight of Kebumen Ongole Grade (PO) cattle at puberty. The data used in this research was weight recordings of (768) PO cattle, ranging from calf (< 1 month) to adult (60 months), collected by Kebumen PO cattle Breeder Association (ASPOKEB) from 2013 to 2015. These cattle were reared by a group of farmers located in six sub-districts: Mirit, Lembu Purwo, Ambal, Puring, Petanahan, and Klirong in Kebumen district, Jawa Tengah Province. Brody, Bertalanfy, Logistic and Gompertz mathematical models were used to analyze the data. The analysis showed that the R2of the four models classify high in the category (R2 >0.70). Mature weight (A) of PO cattle predicted by Logistic (349 kg) and Gompertz (358 kg) were most appropriate. Out of the four models, the Logistic model was the most accurate in predicting the weight at puberty (174 kg) of PO cattle, but all observed cattle are still in the follicular phase.

           on carcass quality of broiler

    • Authors: J. S. Mandey, Y. H. S. Kowel, M. N. Regar, J. R. Leke
      Pages: 240 - 246
      Abstract: This study was conducted to investigate the effect of different level of energy and crude fiber in diets containing sawdust on carcass quality of broilers. A total of 120 broilers were used for the research. The experiment utilized a completely randomized design in 2 x 3 factorial arrangement of treatments consisting of two dietary concentrations of energy and three dietary concentrations of crude fiber. Each treatment consisted of 4 replications (5 birds each) was reared during 35 days. The birds were housed in battery cages with ad libitum access to feed and water. During the experiment, feed intake, carcass yield, abdominal fat, blood LDL-cholesterol and HDL-cholesterol were measured. Data were subjected to the analysis of variance test followed by least significant difference test (LSD). Results showed that the diet with 3,100 Kcal/kg ME and 11% crude fiber significantly decreased feed intake, abdominal fat percentage, and blood LDL-cholesterol, but did not affect final body weight and the value of blood HDL-cholesterol and had the good value of carcass percentage. The diets containing sawdust with higher level of energy content decreased feed intake and the higher level of crude fiber decreased final body weight, carcass percentage and abdominal fat. Optimum broiler performance and carcass quality was obtained by diet formulated to contain 3100 Kcal/kg ME and 11% crude fiber.

  • Evaluation of some insects as potential feed ingredients for ruminants:
           chemical composition, in vitro rumen fermentation and methane emissions

    • Authors: A. Jayanegara, N. Yantina, B. Novandri, E. B. Laconi, N. Nahrowi, M. Ridla
      Pages: 247 - 254
      Abstract: This experiment was aimed to evaluate chemical composition, in vitro rumen fermentation, digestibility and methane emissions of some insects, i.e. Jamaican field cricket (JFC), mealworm (MW) and black soldier fly larvae age 1 and 2 weeks (BSF1 and BSF2). Insect samples were oven-dried at 60oC for 24 h, and ground to pass a 1 mm sieve. The ground samples were used subsequently for chemical composition determination and in vitro rumen fermentation test. Incubation was carried out in a water bath maintained at 39 ºC for 48 h in three replicates. Results revealed that all insect meals contained high crude protein, i.e. above 40% DM. Proportions of neutral detergent insoluble CP (NDICP) and neutral detergent insoluble CP (ADICP) were high in the insect meals than that of soybean meal (SBM), and these were particularly very high in BSF2. All insect meals had lower IVDMD and IVOMD than that of SBM (P<0.05). All insect meals had lower methane emissions as compared to SBM at 12, 24 and 48 h (P<0.05). It can be concluded that insect meals are potential protein supplements and have low methane emissions in vitro. However, their digestibility is rather low and may limit their utilization.

      Abstract: This study was conducted to analysis the effect of levels of white kabesak (Acacia leucophloea Roxb.) Willd. leaves in the diet on feed intake, digestibility and body weight gain of Kacang goats. The completely randomized block design using 5 treatments and 5 replications was used in this experiment. The treatments were 5 concentrate feeds containing different levels of white kabesak leaves i.e. 0, 10, 20, 30 and 40% in the dry matter (DM) basis (representing T0, T1, T2, T3 and T4 treatments, respectively). The feeds were set up to contain 11.5-12.5% of crude protein (CP). Concentrate feed and native grass was fed at ratio of 60 : 40 was fed to 5 local male goats (age 1-1.5 years old and initial weight of 16.7±5.0 kg). The results showed that DM, organic matter (OM), and CP intake of T0 was not significantly different from those of T1 goats, but it was significantly higher (P<0.05) than those of T2, T3 and T4. The DM, OM, CP, and crude fiber (CF) digestibility as well as body weight gain in T2 goats were significantly higher (P<0.05) and had feed conversion ratio that was significantly better...

      Pages: 263 - 269
      Abstract: This study aimed to investigate the effect of decocted turmeric on performance, haematological parameters and carcass traits of broilers. Broiler chicks at 11 days of age were allotted to five groups, including T0 (birds drinking 100% water), T1 (25% decocted turmeric + 75% water), T2 (50% decocted turmeric + 50% water), T3 (75% decocted turmeric + 25% water) and T4 (100% decocted turmeric). The study was arranged based on a completely randomized design (CRD), parameters investigated was performance and blood chemistry (leukocyte, total protein, albumin, globulin, uric acid, glucose). The data were subjected to analysis of variance at 5% probability. Decocted turmeric did not affect weight gain, feed and water consumption and feed conversion ratio of broilers. Lymphocytes proportion was higher (P<0.05) in T1, T2 and T4 than in T0 and T3 birds. The heterophils to lymphocytes ratio was lower (P<0.05) in birds receiving decocted turmeric than control. Globulin concentration and albumin to globulin ratio were higher and lower (P<0.05), respectively, in serum of T2, T3 and T4 than T0 and T1 birds. The proportion of heterophils and concentration of serum total protein, albumin, uric acid and glucose were not different among treatments. The weight of breast meat was higher and lower (P<0.05) in T3 and T4 birds, respectively, compared to the control. In conclusion, providing decocted turmeric through drinking water helped to improve stress responses and increased the weight of breast meat of broiler chickens.

  • The expression of heat shock protein 70 gene with organic selenium
           supplementation and its effetc on productivity of broilers in tropical
           environment

    • Authors: R. Amizar, S. Suharti, J. Jakaria, R. Mutia
      Pages: 279 - 287
      Abstract: The purpose of this experiment is to study the effect of organic selenium (Se) supplementation on the expression of heat shock protein 70 gene (HSP70), glutathione peroxidase (GSH-Px) enzyme activity, malondialdehyde (MDA) and productivity of broilers in tropical environment. Three kinds of environmental pens were designed in this experiment: comfortable environment pens with temperature of air conditioner adjusted at 22oC (R0), tropical environment pens (±30oC ) without organic Se (R1), and tropical environment pens supplemented with 0.30 ppm organic Se (R2). One hundred and twenty broiler chickens (unisex) were used in this study. There were 40 chicks per pen for each treatment. The experimental design was completely randomized with four replications for each treatment. The data were statistically analyzed using the general linear model of SAS program. Results showed that R0 and R2 groups had significantly increased (P<0.05) feed intake, body weight, body weight gain, and decreased feed conversion ratio compared to R1 groups. Meanwhile, the expression of HSP70, GSH-Px enzyme activity and MDA of R2 groups and R0 groups were significantly lower (P<0.05) than that of R1 groups. It was concluded that the broilers given 0.30 ppm organic Se in tropical environment had similar productivity and expression of HSP 70 with broilers kept in comfortable environment.
