Female mules can’t reproduce naturally. But researchers found they can make excellent surrogate dams for embryo transfer.
Factors that contribute to a breeder’s likelihood of getting a live foal using intracytoplasmic sperm injection.
Dr. Regina Turner shared her favorite breeding-related studies on topics ranging from foaling prediction to estrus suppression.
Owners and veterinarians involved with two small-scale horse breeding operations share their secrets to success.
Is your mare’s competitive career progressing, but you’d like to get a foal from her? Dr. Ryan Ferris gives an overview of how much time a mare needs off training for assisted reproductive techniques, such as embryo transfer.
Current horse breeding trends are characterized by a decline in mares bred and a new focus on well-being of established pregnancies, as well as enhanced genetic selection related to the health and future performance of foals.
Given the right conditions, equine embryos produced in a lab using ICSI can lead to pregnancy rates of approximately 70%, researchers say.
Researchers identified three ways to help improve pregnancy and foaling rates: breeding mares multiple times in a season, inseminating close to ovulation, and choosing a stallion with progressively motile sperm.
Equine reproduction specialist Dr. Ryan Ferris explains basics new horse breeders need to know, including mare estrus cycles and selecting fresh vs. frozen semen.
Researchers identified a 90% pregnancy rate in mares impregnated using the Wilsher embryo transfer technique and a 70% pregnancy rate in mares treated using traditional embryo transfer protocols.
Researchers found that 90% of stem-cell-cloned foals were “completely healthy and normal” at birth, whereas two-thirds of the skin-cell-cloned foals were not.
Where do we go from here? Find out from Charlie Scoggins, DVM, MS, Dipl. ACT, who’s a fertility clinician at Rood & Riddle Equine Hospital in Lexington, Kentucky.
A reproductive specialist describes techniques to help clinicians overcome common challenges in embryo recovery and recipient mare management.
Ejaculate with less than 20% urine contamination might be suitable for freezing without centrifugation.
This can pose a problem for mare owners working with a limited breeding window due to the short lifespan of the mare’s oocyte and the stallion’s sperm.
Study results revealed promising pregnancy rates with embryos that weren’t frozen in a laboratory but in a barn.
