Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).
