The lipidomic secretions of embryos provide a unique opportunity to examine the cellular processes of the early conceptus. In this study we profiled lipids released by the early equine conceptus, using high-resolution mass spectrometry to detect individual lipid species. This study examined the lipidomic profile in embryo-conditioned media from -produced, 8-9 day-old equine embryos ( = 3) cultured for 36 h, analyzed over 3 timepoints.

This study shows that PAF is present in the reproductive tissues of mares and is involved in processes related to ovulation and early pregnancy.
Abstract: Platelet-activating factor (PAF) has been implicated in a number of reproductive processes ranging from ovulation to embryo motility but has not been widely explored in the mare.
Primary cosmic ray particles comprise about 85 % protons, 12 % helium, 3 % iron, and heavier elements. These particles interact with the Earth's atmosphere, generating the Extensive Air Showers (EAS). Among the particles produced are pions and kaons, which decay into cosmic ray muons.

This study aimed to evaluate the effects of pre-, pro- or synbiotic supplementation on fecal and semen microbiome composition and sperm quality parameters of stallions. This Latin square crossover trial involved four miniature pony stallions receiving control diet only, or addition of a pro-, pre- or synbiotic formulation.

Aims: To describe the microbiota detected in equine semen of healthy miniature pony stallions.
Methods: Semen specimens were collected using a Missouri artificial vagina at a single time point.
