Genetic and Phenotypic Correlations Among Growth, Disease Occurrence, and Reproductive Performance From Calf to Heifer in Girolando Dairy Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Girolando breed, a cross between Holstein (Bos taurus) and Gir (Bos indicus), is the primary choice for dairy production in Brazilian tropical regions, as it combines high productive potential with adaptation to the tropical environment.

The Polled Locus Maps to BTA1 in a Bos indicus x Bos taurus Cross [PDF]

open access: yesJournal of Heredity, 1996
Two hundred and nine reciprocal backcross and F2 progeny produced by embryo transfer from Angus (Bos taurus) and Brahman (Bos indicus) parents and their 60 parents and grandparents were utilized to localize the locus (POLL) responsible for the polled phenotype in a genetic map of bovine chromosome 1.

Prey restoration facilitates early tiger recolonization in a human‐dominated protected area of Thailand

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Rewilding is an important ecological restoration practice for sustaining ecosystem function. Reintroduction of large‐ and medium‐sized prey can facilitate recolonization by predators such as tigers (Panthera tigris) in fragmented habitats.

Alternative genotyping method for the single nucleotide polymorphism A2959G (AF159246) of the bovine CAST gene Método alternativo de genotipagem do polimorfismo de nucleotídeo único A2959G (AF159246) do gene CAST bovino

open access: yesPesquisa Agropecuária Brasileira, 2008
The objective of this work was to genotype the single nucleotide polymorphism (SNP) A2959G (AF159246) of bovine CAST gene by PCR-RFLP technique, and to report its use for the first time. For this, 147 Bos indicus and Bos taurus x Bos indicus animals were

Contemporary Management of Human‐Caused Hybridization in Mammals: A Review

open access: yesMammal Review, Volume 56, Issue 4, December 2026.
By reviewing studies on human‐mediated (i.e., anthropogenic) hybridization, we identify key management gaps, including inconsistent identification of admixed individuals, limited population‐level assessments, insufficient social engagement, and unclear management objectives.

Evaluation of carcass characteristics and meat chemical composition of Bos indicus and Bos indicus x Bos taurus crossbred steers finished in pasture systems

open access: yesBrazilian Archives of Biology and Technology, 2003
The objective of this study was to evaluate the carcass characteristics (carcass weight, carcass yield, fat thickness, loin area, marbling and colour) and chemical composition of the Longissimus dorsi muscle (moisture, ash, crude protein, fat and ...

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3297-3329, November 2026.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Weighted Single‐Step GWAS Reveals Genetic Mechanisms Underlying Pregnancy Loss in Early Nellore Heifers

open access: yesAnimal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Pregnancy loss (PL) affects reproductive efficiency in beef cattle, yet its genetic architecture remains poorly understood in Bos indicus populations. Here, PL was defined as failure from pregnancy diagnosis to calving, capturing a window approximately 60 days after the breeding season.

Morphological dimorphism in the Y chromosome of "pé-duro" cattle in the Brazilian State of Piauí

open access: yesGenetics and Molecular Biology, 1999
"Pé-duro" (hard foot) is a rare breed of beef cattle of European (Bos taurus taurus) origin, originated in northern and northeastern Brazil. Y chromosome morphology, outer genital elements and other phenotypic characteristics were examined in 75 "pé-duro"
