Abstract
There is lack of comprehensive studies on the genetic diversity or phylogenetic analysis of beef cattle breeds in Malaysia. In this study the partial sequence of mitochondrial DNA cytochrome b gene (cyt b) was analysed from blood samples obtained from 25 Chinese Yellow Cattle (CY) 33 Kedah-Kelantan (KK) 32 Brakmas (BM) and 30 Bali cattle (BC). Based on these 120 individuals 19 mtDNA haplotypes (GenBank Accession No. GU67340 - GU67358) were identified by polymorphisms at 31 sites. Hap19 was predominant in BM (78) KK (82) and CY (100) indicating similar origin or gene flow between breeds whilst Hap11 was exclusively for BC. However there were only two nucleotide differences between these two major haplotypes. These results can be interpreted that these representative cattle in these haplotypes are admixtures of B. indicus or B. javanicus through maternal ancestry. Conversely the CY cattle investigated are highly inbred where no variation could be observed in the short segment investigated.
