Assessing Bos taurus introgression in the UOA Bos indicus assembly [PDF]

open access: yesGenetics Selection Evolution, 2021
Abstract Background Reference genomes are essential in the analysis of genomic data. As the cost of sequencing decreases, multiple reference genomes are being produced within species to alleviate problems such as low mapping accuracy and reference allele bias in variant calling that can be associated with the alignment ...

Longevity Attributes of Bos indicus × Bos taurus Crossbred Cows11Published with approval of the Director of the Kentucky Agricultural Experiment Station as Journal Article 03-07-028.

open access: hybridThe Professional Animal Scientist, 2003
Abstract Bos indicus × B. taurus, especially Brahman × B. taurus, crossbred females express a high level of preweaning productivity during a relatively long life span; however, for reasons such as subpar reproductive performance of Brahman bulls, price discrimination for contemporary steer and heifer mates, and older age at puberty, these females can

Y chromosome variants in cattle Bos taurus and Bos indicus [PDF]

open access: yesGenetics Selection Evolution, 1982
Summary It is shown that comparison of the size of the Y chromosome between individuals may be made as reliably by computation of measurement relative to the X chromosome as by proportionation relative to the genome in the cell. By either method agreement was found with previous studies : first in placing the Y in the size range, for the cattle ...

In vitro performance of Zebu (Bos indicus) and Taurus (Bos taurus) donor cow embryos [PDF]

open access: yesRevista Brasileira de Saúde e Produção Animal, 2020
ABSTRACT In this study, the in vitro production of bovine embryos from zebu and taurine donors was compared. Cumulus-oocyte complexes (COCs) were obtained from 167 Bos taurus and 161 Bos indicus donors by ovum pick-up. COCs were classified based on their morphological quality, matured in incubators for 22 to 24 h in maturation medium, and then ...

Cattle phenotypes can disguise their maternal ancestry

open access: yesBMC Genetics, 2017
Background Cattle are bred for, amongst other factors, specific traits, including parasite resistance and adaptation to climate. However, the influence and inheritance of mitochondrial DNA (mtDNA) are not usually considered in breeding programmes.
