Modern Reproductive Technologies to Horse Breeding
Although the horse was probably the first animal to experience and benefit from artificial insemination, it trailed the field somewhat with regard to the application of embryo transfer and other oocyte and embryo-related modern breeding technologies. A very interesting new article!

But with a late run it is now back in mid-field and gaining fast on the other large domestic species in the application of the many technological advances of the past 20 years to sound breeding practice.

Improvements in extenders and cryoprotectants have resulted in a veritable upsurge in the transport and insemination of cooled and frozen stallion semen, and parallel improvements in ovulation induction and synchrony, exogenous gonadotrophic stimulation of multiple fertile ovulations and simplified, more efficient methods for non-surgical transfer of embryos to recipient mares, coupled with relaxation of breed society registration restrictions, have together contributed to a similar upsurge in the application of embryo transfer to all breeds and athletic types of horses worldwide, with the continuing and notable exception of the Thoroughbred.

Although conventional in vitro fertilization remains something of an unjumped fence in equids, other modern breeding technologies like hysteroscopic low-dose insemination, fluorescence-activated sex sorting of stallion spermatozoa, between-species embryo transfer, embryo freezing and bisection, transvaginal ultrasound-guided oocyte collection, intracytoplasmic sperm injection for fertilization (ICSI), gamete intrafallopian transfer (GIFT) and now nuclear transfer (cloning), have all been applied to equids with encouraging success.

Cloning, especially, holds enormous promise for the Sporthorse industry to re-create champion geldings in stallion form for breeding purposes.

Two regimens of lidocaine infusion in horses undergoing laparotomy for colicmembers
Various lidocaine protocols are described for horses undergoing Colic surgery. This interesting prospective, randomized clinical study compares the effects of administering or not administering a loading intravenous (IV) bolus of lidocaine prior to its constant rate infusion (CRI). Effects investigated during isoflurane anaesthesia were end-tidal isoflurane concentration (Fe′ISO), cardiovascular function, anaesthetic stability and the quality of recovery.
Thirty-six client-owned horses were enrolled.

  • Biofilms of Candida spp. from the ocular conjunctiva of horses members
  • PARR clonality testing in a horse with a solitary retropharyngeal lymphomamembers
  • New sensor design for buccal pulse oximetry in horsesmembers
  • Uterine isolates and antimicrobial susceptibility in mares with post-partum metritismembers
  • Right ventricular function during acute exacerbation of severe asthma in horsesmembers
  • Biuret versus refractometry methods to measure serum total proteins in ruminantsmembers
  • Steatitis in equids - clinical and ultrasonographical findingsmembers
  • Correlation of overground endoscopy to resting laryngeal function in racehorsesmembers
  • Pigment retinopathy in warmblood horses with EMNDmembers
  • Maxillary odontogenic myxoma in six young horsesmembers
  • Managing equine ataxia due to cervical vertebral stenotic myelopathymembers
  • Pirfenidone to treat equine corneal scarringmembers
