Selection using genetic markers are commonly performed to improve livestock productivity in the livestock industry. The objectives of this study were to identify growth hormone genes family (GH|MspI, GH|AluI, GHR|AluI, GHRH|HaeIII and Pit-1|HinfI) polymorphisms of Banten buffalo population consisted of Pandeglang and Lebak subpopulations. A total number of 209 blood samples were collected from 15 districts. Genomic DNAs were extracted by a standard phenol-chloroform protocol and amplified by a polymerase chain reaction (PCR) techniques, then PCR products of GH, GHR, GHRH and Pit-1 Genes were digested with MspI, AluI, HaeIII and HinfI enzyme restriction. Fragments of GH|MspI, GH|AluI, GHR|AluI, GHRH|HaeIII and Pit-1|HinfI were detected by EtBr method. The results showed that GH|MspI and GHRH|HaeIII loci were polymorphic, GH|AluI, GHR|AluI and Pit-1|HinfI, loci were monomorphic. GH allele (-) at locus GH|MspI was only found in Cisata (0.03) and Menes (0.11). Allele B at locus GHRH|HaeIII only found in Cibadak (0.42), Cisata (0.30) and Menes (0.11). In the total population of Banten locus GH|MspI have low diversity (He = 0.02) and polymorphic information content (Pic = 0.02), whereas GHRH|HaeIII locus has a higher diversity (He = 0.23) and Pic (0.22).

Kappa casein (ĸ-cn) gene as one of the four casein genes commonly has two variant alleles. B allele is positively correlated with milk proteins, so potentially be used as MAS to improve milk protein content. This study aimed to identify genetic variation of the ĸ-casein gene in Holstein-Friesian (HF) from several dairy regions in West Java. Blood samples were taken through jugular vein of lactating heifers and cows, from intensive managements under the Local Government Dairy Breeding Station - Cikole (BBPT Cikole-SP) (82 hds), Embryo Transfer Station (BET) (50 hds), and Eco Farm of Animal Science Faculty of Bogor Agricultural University (EcoFarm) (20 hds); as well as from semi-intensive managements of small dairy farmers under the supervision of the North Lembang Cooperative Unit (KPSBU Lembang) in two villages of Cilumber (98 hds) and Pasar Kemis (92 hds). Blood samples were also taken via cocsigalis vein of AI (active and non active) HF bulls at the two National AI Stations in Lembang (25 hds) and Singosari (32 hds). Identification of genetic variation was by applying PCR-RFLP method. Three genotypes were identified, namely AA, AB, and BB, resulting two alleles of A and B. Results entirely showed that the frequencies of the BB HF female were very low, with the range of 0%-6% (vs AA genotype= 10%-54% and AB genotype= 46%-85%), despite of the relatively high frequency of the B allele over the A allele (23%-48% vs. 52%-77%). The low frequency of the observed BB females might be due to the limited AI active BB bulls used for services by the two national AI stations (0%-4%).

Falsification of the origin of livestock meat and its processed with rat meat is a problem that must be overcome to ensure food safety. One way that is often used to detect forgeries by using cytochrome b gene as a marker. The purpose of this study was to create a specific primer derived from cytochrome b sequences in rat (Rattus norvegicus) as the DNA marker to detect any contamination of rat meat on fresh livestock meat and its processed meat products. Meatballs were made from beef meat with the addition of rat 1%-25%, and the meatballs were obtained from traditional markets. DNA extraction was conducted from seven species (goat, chicken, cattle, sheep, pig, horse, and rat) by using phenol-chloroform. The highest success rate in detecting the presence of rat meat in a mixture of beef meatballs at concentration of 15% was 100%. The specific fragment of cytochrome b gene in R. norvegicus has no similarity with the cytochrome b gene from six other species, so it can be used as molecular markers to detect the presence of rat meat contamination in the processed of meat products. Amplified fragment length for goats, chickens, cattle, sheep, pigs, horses, and rats 157, 227, 274, 331, 398, 439 and 603 bp respectively. The amplification of cytochrome b gene in seven species of animals with different fragment length indicated the specificity of cytochrome b gene sequences among species.

Growth hormone gene (GH gene) plays an important role in regulating body growth and in developing mammary gland, similar with its interaction to specific receptors. The GH gene has been considered as one of candidate gene associated with selection on lactation trait and milk production. This study was aimed to determine genetic polymorphism of the GH-AluI gene and to associate its genotype variants on various 15-d partial cumulative milk yields in Holstein Friesian (HF) dairy cows. A number of 370 blood samples were collected from six HF populations, respectively from small dairy farmer under the supervision of the North Bandung Milk Cooperation (NBMC) in Cilumber (98) and Pasir Kemis village (96), Dairy Cattle Breeding and Improvement Station (Cikole DCBIS) Cikole (88), Lembang Artificial Insemination Center (Lembang AIC) (17), Singosari Artificial Insemination Center (Singosari AIC (32), and Cipelang Livestock Embryo Center (Cipelang LEC) (40). A polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) method was used to identify variant genotypes of the GH gene using AluI restriction enzyme. Genotyping results produced only two genotypes, i.e. LL and LV genotypes, without VV genotype. Frequency of the former was dominant, whilst that was low for the latter (89% vs. 11%); leading to the frequency of L allele was very high (94%) compared to that of V allele (6%). No significant association between variant genotypes (LL and LV) and various 15-d partial cumulative milk yields.

Bacteriocins produced by Indonesian lactic acid bacteria Lactobacillus plantarum IIA-1A5, IIA-1B1, IIA-2B2 were purified and characterized. Plantaricin W gene had been successfully amplified from all strains. This amplicon showed the expected 200 bp size of plantaricin W gene. This bacteriocins purified from L. plantarum IIA-1A5, IIA-1B1, and IIA-2B2 were named plantaricin IIA-1A5, IIA-1B1, and IIA-2B2. Purification by cation exchange chromatography increased the purity (fold) and activity of plantaricins. Purity of plantaricin IIA-1A5 was increased by 3.13 fold with specific activity 13.40 AU/mg. Plantaricin IIA-1B1 had 2.98 fold purity with specific activity 5.12 AU/mg, while purity of plantaricin IIA-2B2 was 1.37 fold with specific activity 7.70 AU/mg. All plantaricins could inhibit the growth of pathogenic bacteria, such as Escherichia coli, Salmonella typhimurium, Bacillus cereus, and Staphylococcus aureus. Plantaricins could be digested by trypsin. Stability of plantaricins at 80 oC for 30 min and at 121 oC for 15 min were affected by type of plantaricin and species of pathogenic bacteria. Generally, plantaricin IIA-1A5 was better as antimicrobial agent than plantaricin IIA-1B1 and plantaricin IIA-2B2.
