First Equine Embryo Time-Lapse Images Revealed – The Horse

Do you think horses are quick to get moving right after birth? Check out what they’re doing right after fertilization.

Through studying the first several days of development in time-lapse videos, Lewis and her fellow researchers determined that early cleavage (the separation of a cell into two or three cells) is key, she said. Specifically, when the zygote (the single-cell product of egg fertilization) pushes out some of its cytoplasm and then divides within the first 24 hours, it’s much more likely to later become an embryo with a heartbeat.

Previous research had already pointed to this 24-hour window for cleavage, said Lewis. But their study visually confirmed the importance of the timing of this event.

In their study, Lewis and her fellow researchers created 144 equine zygotes through intracytoplasmic sperm injection (ICSI). They placed each injected oocyte (egg) in a droplet of culture medium and set it under a camera that would take images automatically every five to 10 minutes, for about the first 10 days of development. Afterward, they combined the images into a playback mode that generates a video of each embryo’s development.

Study: Mobile App Gives Reliable Equine Semen Analysis – The Horse

"What’s in that straw? Stallion semen, sure. But what quantity, and what quality?

Unless your farm is equipped with expensive, nonportable, high-tech equipment, qualifying semen for artificial insemination operations likely involves a lot of guesswork. A new computer-based program working off an electronic tablet (iPad), however, is bringing reliable information about concentration, motility, and other critical semen aspects right into the breeding barn, according to Belgian researchers. In fact, its results run close to those you’d get with the higher-priced gold standard equipment.

“It’s amazing how parallel the two systems are, meaning you can rely on the mobile system as much as the fixed laboratory system (for real-time results),” said Peter Daels, DVM, PhD, Dipl. ECAR, ACT, of the Faculty of Veterinary Medicine at Gent University in Merelbeke, Belgium.

A new study carried out by Gent University and the De Morette Equine Reproduction Center in Asse, Belgium, showed that the “iSperm” system provided stallion sperm analysis results in the field that were within 10% of the results obtained by AndroVision and NucleoCounter SP‐100 laboratory devices. These fixed devices aren’t portable and cost upward of 20,000 euros ($23,000)."

Looking for an equine centered college

Can anybody recommend good equine colleges? I want to specialize in breeding/training as well as run my own business so it'll need to have those things included in the program. The school I'm going to doesn't really cut it and the teachers are kind of crap at communicating. Anybody know of any schools?
