Abstract

In the population, there are aggressive sheep in a small number which requires special management those specific animal house and routine management. The purpose of this study was to identify the variation of DNA marker SNP (single nucleotide polymorphism) as a genetic marker for the aggressive trait in several of sheep breed. The identification of point mutations in exon 8 of MAO-A gene associated with aggressive behavior in sheep may be further useful to become of DNA markers for the aggressive trait in sheep. Five of sheep breed were used, i.e.: Barbados Black belly Cross sheep (BC), Composite Garut (KG), Local Garut (LG), Composite Sumatra (KS) and St. Cross Croix (SC). Duration of ten behavior traits, blood serotonin concentrations and DNA sequence of exon 8 of MAO-A gene from the sheep aggressive and nonaggressive were observed. PROC GLM of SAS Ver. 9.0 program was used to analyze variable behavior and blood serotonin concentrations. DNA polymorphism in exon 8 of MAO-A gene was analyzed using the MEGA software Ver. 4.0. The results show that the percentage of the aggressive rams of each breed was less than 10 percent; except for the KS sheep is higher (23%).  Based on the duration of behavior, aggressive sheep group was not significantly different with non aggressive sheep group, except duration of care giving and drinking behavior. It is known that concentration of blood serotonin in aggressive and non aggressive rams was not significantly different. The aggressive trait in sheep has a mechanism or a different cause like that occurs in mice and humans. In this study, aggressive behavior in sheep was not associated with a mutation in exon 8 of MAO-A gene. Key Words: Sheep, Aggressive, Exon 8 Of MAO-A Gene, Single Nucleotide Polymorphism

Abstract

This study aimed to determine the Pit-1|Hinf-1 gene polymorphism in Bali cattle (Bos javanicus) as Indonesian native cattle and besides Madura, Pesisir, Aceh, and Katingan cattle breeds as a comparison. DNA samples were extracted from 488 blood samples consisting of Bali (245 heads), Madura (68 heads), Aceh (25 heads), Pesisir (100 heads) and Katingan (50 heads) cattle. The diversity of the Pit-1|Hinf-1 gene wasere analyzed using PCR-RFLP. Whereas the nucleotide base mutations were identified by sequencing. Genotyping data were analyzed by calculating the allele frequency, observed heterozygosity (Ho) and expected heterozygosity (He) values as well as Hardry-Weinberg equilibrium test using POPGENE 1.31 program. Whereas, Tthe sequence data were analyzed by using MEGA6 program. The Pit-1|Hinf-1 gene fragment analysis showed that Bali, Madura, Pesisir, Aceh, and Katingan cattle had high BB genotype, resulting in B allele frequency of 0.982, 0.963, 0.925, 0.960, and 0.960, respectively. Ho and He values were 0.074-0.130 and 0.036-0.139, respectively. Hardy-Weinberg equilibrium test did not significant for all breed populations, except for Aceh cattle population (P<0.05). Mutation from guanine (G) to adenine (A) was found in Pit-1 gene fragment. Therefore, Pit-1|Hinf-1 gene fragment had low genetic diversity in Bali cattle and other breeds population.Key words: Bali cattle, Pit-1|Hinf-1 gene, polymorphism
