Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Evaluation of Linkage Disequilibrium, Effective Population Size and Haplotype Block Structure in Chinese Cattle [PDF]

, 2019
Understanding the linkage disequilibrium (LD) across the genome, haplotype structure, and persistence of phase between breeds can enable us to appropriately design and implement the genome-wide association (GWAS) and genomic selection (GS) in beef cattle.

Genome‐Wide Association Study (GWAS) for Linear Body Measurements of Sussex Cattle (Bos taurus) at Weaning and Yearling Age in South Africa

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
These results show that GWAS can be a useful tool for recognising novel loci and unravelling the genetic basis of complex economic traits. Sussex cattle exhibited candidate genes (RAB31, BIRC5, TEX22, CFAP100 and LOC617705) as potential candidate genes for linear body measurement traits, which could serve as significant marker information for genome ...

Comparative Fluctuating Asymmetry and Directional Asymmetry in Four Cattle Skulls

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This graphical abstract illustrates the comparison of directional asymmetry (DA) and fluctuating asymmetry (FA) in the skulls of four cattle breeds (Eastern Anatolian Red, Southern Anatolian Red, Holstein and Simmental). Using geometric morphometrics (3D landmarks, Procrustes analysis, PCA and ANOVA), 89 skulls were analysed.

Maternal Liver Retinol Stores Do Not Ensure Adequate Calf Vitamin A Under Restricted Late‐Gestation Vitamin A Intake

Animal Science Journal, Volume 97, Issue 1, January/December 2026.
ABSTRACT Vitamin A is critical for immune function and epithelial integrity, yet the relationship between maternal and calf vitamin A status is not well defined. This study evaluated cow–calf vitamin A status under restricted maternal vitamin A intake during late gestation and early lactation.

Bovine Leukemia Virus: Global Prevalence and Localized Resurgence in China Revealed by an Integrated Meta‐Analysis and Case Series

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Background Bovine leukemia virus (BLV), the causative agent of enzootic bovine leukosis (EBL), causes substantial economic losses in the global cattle industry. While some regions have made progress in terms of control, the global epidemiological landscape and situation in China have not been fully elucidated.

Epidemiological Insights Into BVDV and IBRV in Feeder Cattle After Cross‐Regional Transport in China 2022–2024: Coinfection Dynamics and Implications for BRDC Control

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Background Bovine viral diarrhea virus (BVDV) and infectious bovine rhinotracheitis virus (IBRV) are key components of the bovine respiratory disease complex (BRDC) in China’s cross‐regional feeder system. We quantified antibody and antigen positivity and identified epidemiological determinants across provinces, seasons, years, and clinical status ...
