Circumocular pigmentation and incidence of ocular squamous cell tumors in Bos taurus and Bos indicus × Bos taurus cattle [PDF]
Journal of the American Veterinary Medical Association, 1990 Summary Amount of circumocular pigmentation and incidence of ocular squamous cell tumors were evaluated in dams representing diverse cattle breed types. Each dam was examined twice annually during a specific stage in the life cycle (3.5 to 9.5 years old). Overall, 28.3% of dams in the herd developed at least 1 ocular squamous cell tumor.

Oocyte quality in adapted Bos taurus taurus cows
Animal Biotechnology, 2023 The objective of the current study was to determine the performance of creole cows of the Chino Santandereano breed in the ultrasound-guided follicular aspiration technique (OPU) and the quality of oocytes recovered. A total of 15 multiparous cows were selected from a herd located in the department of Santander with tropical climate.

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

Sequence analysis in Bos taurus reveals pervasiveness of X–Y arms races in mammalian lineages
Genome Research, 2020 Studies of Y Chromosome evolution have focused primarily on gene decay, a consequence of suppression of crossing-over with the X Chromosome. Here, we provide evidence that suppression of X–Y crossing-over unleashed a second dynamic: selfish X–Y arms ...

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