PMID 42278060 — The Role of Omega-3 Fatty Acids in Horses' Nutrition-A Review. (Animals : an open access journal from MDPI, 2026). Abstract (opening): This narrative review presents examples of omega-3 fatty acids supplementation in horse nutrition. Fats are essential in equine nutrition, serving not only as an energy source but  *[CC BY — Open Access, verbatim with attribution.]*\n2. PMID 42098815 — *[Paraphrased derived summary — non-Open-Access source.]* A study using LC-MS and 16S amplicon analysis examined the effects of citrulline on horse milk components and fecal metabolism in lactating mares; the authors note the lactation period critically influences foal health and reproductive outcomes and aimed to develop a nutritional strategy for lactating mares (BMC Vet Res, 2026).

PMID 42309331 — *[Paraphrased derived summary — non-Open-Access source.]* A practical review of conventional equine embryo transfer (ET), a well-established procedure used to increase offspring from valuable mares or obtain embryos from mares unable to carry, covering factors for success (J Equine Vet Sci, 2026). (Source excerpt truncated at abstract opening.)\n4. PMID 41689060 — Effects of L-selenomethionine supplementation on nutrient digestibility and metabolism, antioxidant capacity, hormone levels, and fecal microbiota diversity in pregnant Yili mares during mid- to late gestation. (BMC veterinary research, 2026). Abstract (opening): BACKGROUND: L-selenomethionine (L-SeMet), a highly bioavailable organic form of selenium, plays a critical role in maintaining antioxidant homeostasis, regulating reproductive horm *[CC BY — Open Access, verbatim with attribution.]*\n5. PMID 42102861 — *[Paraphrased derived summary — non-Open-Access source.]* A retrospective study of 76 Thoroughbred broodmares (2000–2023) undergoing surgical repair of periparturient uterine tears described clinical presentation, treatment, short- and long-term outcomes, and subsequent fertility (JAVMA, 2026).
