Bos indicus, the zebu

open access: yes, 2008
Zebus or humped cattle are the typical cattle of the South Asian subcontinent. At present, there are thirty or more zebu breeds in India. The recognized breeds differ mainly in the shape and firmness of the hump, horn size, ranging from long-horned to very short-horned or even almost rudimentary horns, and horn shape, ranging from lyre-shaped through ...

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

open access: yesFunctional Ecology, Volume 40, Issue 8, Page 2379-2391, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Coding and Noncoding Uterine Small Extracellular Vesicle Content Differs in the Early Stages of Pregnancies Produced by Artificial Insemination and In Vitro Fertilization in Cattle

open access: yesMolecular Reproduction and Development, Volume 93, Issue 7, July 2026.
ABSTRACT Establishing a successful pregnancy relies on effective communication between the mother and fetus. Small extracellular vesicles (sEVs) are pivotal in facilitating intercellular communication, transferring messenger RNA (mRNA), noncoding RNA (ncRNA), and proteins. Considering the prevalence of in vitro fertilization (IVF) in bovine production,

Population Structure, and Selection Signatures Underlying High-Altitude Adaptation Inferred From Genome-Wide Copy Number Variations in Chinese Indigenous Cattle

open access: yesFrontiers in Genetics, 2020
Copy number variations (CNVs) have been demonstrated as crucial substrates for evolution, adaptation and breed formation. Chinese indigenous cattle breeds exhibit a broad geographical distribution and diverse environmental adaptability. Here, we analyzed

Asymmetrical Steps: Osteomorphological and Metric Patterns of Cattle Phalanges to Determine Anatomical Position

open access: yesInternational Journal of Osteoarchaeology, Volume 36, Issue 4, Page 1013-1025, July/August 2026.
ABSTRACT This study presents a reproducible framework for identifying the anatomical position of cattle phalanges, integrating both morphological and osteometric approaches for application to modern and zooarchaeological assemblages. The dataset comprises 1853 phalanges from 106 individuals with known and unknown phalangeal position representing ...

Status of On‐Farm Artificial Insemination Services and Effectiveness of Oestrus Synchronization in Dairy Cattle Under Small‐Scale Dairy Farming System

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Cross‐sectional survey and retrospective data on the oestrus synchronization were collected and analysed. The predominant mating system practiced by dairy farmers was AI (55.6%), and 73.5% of farmers apply controlled mating. The highest response rate and pregnancy rate were 89.5% and 45.2%, respectively, whereas a birth rate of 9.6%–18.5% was obtained.

Quantitative trait locus affecting birth weight on bovine chromosome 5 in a F2 Gyr x Holstein population

open access: yesGenetics and Molecular Biology, 2005
Segregation between a genetic marker and a locus influencing a quantitative trait in a well delineated population is the basis for success in mapping quantitative trait loci (QTL). To detect bovine chromosome 5 (BTA5) birth weight QTL we genotyped 294 F2

Evaluation of Adaptive, Productive and Reproductive Performance of Boran Dairy Breed in the Lowland Agro‐Ecology of Kaffa Zone, South‐Western Ethiopia

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Boran dairy cattle demonstrated acceptable productive, reproductive and adaptive performance under lowland conditions of south‐western Ethiopia. Significant effects of parity and lactation stage were observed on milk yield and blood parameters, while physiological values remained within normal ranges, confirming good adaptation and potential for ...

Prevalence of Stephanofilariasis in young Bos indicus cattle in north Australia

open access: yes, 1988
[Abstract]: Four consecutive annual of calf crops of known genotype from a single property in northern Australia were examined for the presence of stephanofilarial lesions. The animals ranged in age from 60 to 348 at the time of examination.
