Molecular Reproduction and Development, Volume 92, Issue 10, October 2025.ABSTRACT Dairy cows often experience a period of negative energy balance (NEB) during the post‐calving period, which can significantly impact economic outcomes due to extended calving‐to‐conception intervals and overall reduced fertility. This reduction is due, in part, to the impact on uterine biology by high nonesterified fatty acids (NEFA) and beta ...

Assessing the Value of Coordinated Sire Genetics in a Synchronized AI Program [PDF]
Synchronized artificial insemination was used to inseminate cows using different types of sire genetics, including low-accuracy, calving-ease, and high-accuracy. These three calf sire groups were compared to calves born to cows bred using natural service.

Altered progesterone concentrations by hormonal manipulations before a fixed-time artificial insemination CO-Synch + CIDR program in suckled beef cows [PDF]
, 2014 We hypothesized that pregnancy outcomes may be improved by inducing luteal regression, ovulation, or both (i.e., altering progesterone status) before initiating a timed–artificial insemination (TAI) program in suckled beef cows.

Tracing and Capturing the Epiblast Pluripotency of Sheep Preimplantation Embryos
Advanced Science, Volume 12, Issue 36, September 25, 2025.This study performs a comprehensive single‐cell transcriptome analysis of sheep embryos from embryonic (E) day 1 to E14 to elucidate the mechanism of early lineage specification and the pluripotency changes (naïve, formative, and primed) of epiblast.

The Anatomical Record, Volume 308, Issue 9, Page 2413-2432, September 2025.Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Comparison of PUFA profiles in the blood and in follicular fluid and its association with follicular dynamics after PGF2α induced luteolysis in dairy cows [PDF]
, 2016 The objectives of the present study were to examine the fatty acid (FA) profiles in serum and in the follicular fluid (FF) and the association between polyunsaturated fatty acid level (PUFA) and follicular growth dynamics following induced luteolysis in ...
