Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

Journal of Animal Breeding and Genetics, Volume 143, Issue 5, Page 625-638, September 2026.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Voltage‐gated calcium channel activity of gonadotropin‐releasing hormone (GnRH) neurons is altered by age and by prenatal androgen exposure in female mice

Journal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Polyendocrine metabolic ovarian syndrome (PMOS), a common cause of infertility, is marked by persistently high luteinizing hormone (LH) pulse frequency, presumably driven by high‐frequency GnRH pulses. Prenatally androgenized (PNA) mice mimic neuroendocrine PMOS symptoms including high LH‐pulse frequency.

Dietary L‐Tyrosine Sustains Egg Production and Quality by Modulating Promoter CpG Methylation, Gene Expression, and Hormone Profiles in Reproductive Signalling Pathways of Aged Laying Hens

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 685-698, September 2026.
ABSTRACT Managing prolactin (PRL)‐mediated reproductive suppression is critical for maintaining egg production in commercial laying hens. L‐tyrosine (TYR), a precursor of dopamine (DA), may counteract age‐related reproductive decline by suppressing PRL, thereby sustaining productivity and egg quality in late‐phase laying hens.
