Metagenomic analysis exploring taxonomic diversity of rumen microbial communities in Vechur and crossbred cattle of Kerala state, India. J Appl Genet. 2020 Jan 31;: Authors: Sadan T, Aravindakshan TV, Radhika G, Anand LF, Ally K Abstract Rumen, one of the most productive diverse microbial habitats plays a vital role in the breakdown of feed to produce energy for maintenance and milk production in cattle. Culture-based procedures could identify only 10% of microbial species present in the rumen. Kerala, one of the southern states of India, owns only one native cattle breed, the Vechur cattle, which is noted for its short stature, disease resistance and adaptability to hot humid climate. Lower population density and decreased milk production potential of Vechur cattle led to the development of crossbred cattle of Kerala, with higher milk yield. A study was conducted to assess the rumen microbial profile of low productive Vechur cattle and high productive crossbred cattle for a better understanding of the relationship between the host and microbial community. DNA isolated from rumen liquor of five cattle each from both genetic groups maintained on standard ration (forage, concentrate ratio of 50:50) was subjected to whole metagenome sequencing. Bioinformatics and statistical analysis revealed that bacteria followed by archaea and eukaryota dominated in the Vechur cattle as well as the crossbred cattle rumen. Bacterial community was domi...
