Kazakhstani native cattle reveal highly divergent mtDNA from Bos taurus and Bos indicus lineages with an absence of Bos indicus Y chromosome.

Kazakhstan is the largest landlocked country and contains two important propagation routes for livestock from the Fertile Crescent to Asia. Therefore, genetic information about Kazakhstani cattle can be important for understanding the propagation history and the genetic admixture in Central Asian cattle. In the present study, we analyzed the complete mtDNA D-loop sequence and SRY gene polymorphism in 122 Kazakhstani native cattle.

Genetic diversities and population structures of four popular Myanmar local cattle breeds.

Local cattle breeds are popular in Myanmar because they make excellent draught animals, so it is of fundamental importance that their genetic diversities and population structures are elucidated for breeding and conservation purposes. In this study, we characterized the genetic diversities and population structures of four popular Myanmar local cattle breeds and five native cattle populations from neighboring countries (Bangladesh, Laos, Cambodia, and Vietnam) using the GGP Bovine 50K array. The mean observed and expected heterozygosity estimates using pruned datasets ranged from 0.
