Bovine Viral Diarrhoea Virus Across Asia: A Systematic Review and Meta‐Analysis of Prevalence in Cattle Population Between 2000 and 2025

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This systematic review and meta‐analysis summarize the epidemiology of bovine viral diarrhoea virus (BVDV) infection in cattle populations across Asia. Analysis of 133 studies comprising 160,042 cattle revealed a pooled seroprevalence of 40.50% and a pooled antigen prevalence of 9.0% (44,636 cattle). These findings provide an extensive synthesis of the

Is the American Zebu really Bos indicus?

Genetics and Molecular Biology, 1999
The American continent was colonized in the 16th century by Europeans who first introduced cattle of Bos taurus origin. Accounts register introduction of Bos indicus cattle into South America in the 19th and continuing through the 20th century, and most ...

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

Australian Veterinary Journal, Volume 104, Issue 7, Page 447-456, July 2026.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 496-507, July 2026.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus, especially Nellore cattle, remain limited.

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 4, Page 602-612, July 2026.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Endocrine and metabolic differences between Bos taurus and Bos indicus cows and implications for reproductive management [PDF]

, 2020
Based on the considerable differences in ovarian morphology and function, as well as circulating hormones and metabolites between Bos indicus (B. indicus) and Bos taurus (B. taurus), researchers are using this acquired knowledge to optimize protocols for

Mitochondrial control region genetic diversity and maternal ancestry of a Brangus-Ibage cattle populations

Genetics and Molecular Biology, 2005
The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in ...

Influence of MC1R Gene Variants on Coat Color of Indicine Cattle Breeds

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Indicine cattle display a broad range of coat colors, representing a relevant and breed‐defining trait required for registration in breeder association. Among the genes involved in pigmentation, MC1R stands out for modulating the synthesis of melanin‐related proteins and remains poorly explored in indicine cattle breeds. Therefore, we aimed to

The application of geometric morphometric analysis in the study of bovine ovarian morphology

Theoretical and Applied Veterinary Medicine
Geometric morphometrics offers superior analytical capabilities compared to traditional linear morphometry for studying biological shape variation. The bovine ovary serves as an excellent model due to its distinct features and morphological plasticity ...
