Synergistic Effects of Thyroxine and Nano‐Melatonin on Post‐Thaw Sperm Quality, Antioxidant Defence and Fertility of Cryopreserved Simmental Bull Semen

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Effects of thyroxine (T) and nano‐melatonin (NM) supplementation on cryopreserved Simmental bull semen were evaluated. The combination of thyroxine (0.5 µg/dL) and nano‐melatonin (30 µg/dL) significantly improved post‐thaw sperm motility, membrane integrity, antioxidant status, and fertility while reducing oxidative stress and apoptosis. These findings

Gastroschisis‐Like Defect in a Crossbred Bovine Calf: Anatomical, Clinical and Surgical Perspectives

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A gastroschisis‐like defect was observed in a one‐day‐old, crossbred bovine calf with evisceration of the pyloric abomasum and small intestine, likely resulting from prenatal rupture of an omphalocele. The calf presented with lethargy, hypothermia and metabolic derangements, along with elevated renal biomarkers.

Effects of Resveratrol-Loaded Cyclodextrin on the Quality Characteristics of Ram Spermatozoa Following Cryopreservation

Animals
This study investigated the effects of pure and methyl-β-cyclodextrin loaded forms of resveratrol (10 µg/mL, 20 µg/mL, and 40 µg/mL) on ram sperm functions post-thawing. Semen samples were pooled and divided into ten groups: Control, RES10, RES20, RES40,

Total duplication of the femur and polydactyly in the same limb of a Korean native calf

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract This case report describes a neonatal Korean native calf presenting with total duplication of the femur and polydactyly within the same hindlimb—an extremely rare congenital anomaly not previously reported in cattle. The calf exhibited marked structural deformities and inability to stand independently.

The Politics of Reproductive Signification: Navigating Legal Definitions of Parenthood in the Context of UK Informal Donor Conception

Sociology of Health &Illness, Volume 48, Issue 8, November 2026.
ABSTRACT Informal donor conception (IDC) has an ambiguous status under UK law. Whilst not illegal, it is discouraged by regulators and only partially recognised in attributions of legal parenthood. In this paper, we analyse IDC as a lens to explore the politics of reproductive signification.

Population Differentiation and Polygenic Selection in the Finnish Ayrshire Cows Selected on Genomic Information

Journal of Animal Breeding and Genetics, Volume 143, Issue 6, Page 774-783, November 2026.
ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...

Safe and Stable Germline Transmission of MSTN Mutations in Cattle

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT With the global population expected to reach 10 billion by 2050, sustainable livestock production is critical. Gene editing of the myostatin (MSTN) gene represents a promising strategy to enhance muscle growth in cattle. In this study, MSTN‐mutated founder (F0) cows were used to generate F1 offspring via ovum pick‐up, in vitro fertilization ...

Artificial insemination of bitches

, 2013
Umjetno osjemenjivanje je postupak unošenja spermija u spolne organe ženki nakon čega se oplodnja unutar jajovoda odvija prirodnim putem. Prednosti UO pasa su brojne i iz tog razloga interes uzgajivača za UO diljem svijeta brzo raste.
