These factors are magnified in the critically ill foal, said Pamela Wilkins, a professor of equine internal medicine and emergency/critical care at the University of Illinois and the author of a new paper on equine neonatal intensive care. The paper, in Clinical Laboratory Medicine, offers guidance to the large-animal veterinarian and demonstrates the very real challenges of the job.
Sickness can play havoc with a foal’s blood chemistry, Wilkins said. Teasing out the causes of these changes requires that the veterinarian first understand what is normal in a newborn horse, and then how it can go wrong. To help address current gaps in knowledge, Wilkins regularly conducts blood tests or other tests, such as X-rays and CT scans, on healthy foals to determine how their body chemistry or physiology differ from that of an adult horse – or from that of a sick foal.
“Roughly 3 to 7 percent of newborn foals are going to have some kind of significant health issue in the first month of life,” Wilkins said. “And because our patients can’t talk to us, we have to figure out what’s wrong with them based on physical examination and testing and histories given by their owners.”
The paper also offers guidance in the use of portable “point of care” devices to measure and monitor a sick foal’s changing health status. Such tools can offer immediate results in the field and cut costs associated with care. But the practitioner needs to know how use each device and interpret the results, Wilkins said.
“For example, foals with severe infections can have a very, very low or a very high glucose level,” she said. Low blood glucose could be the result of the foal not taking in enough nutrients from its mother. Or the animal may not be able to make use of the glucose that is already stored as glycogen in its body. It’s the practitioner’s job to find out what’s going on, she said.
To do that, veterinarians must understand the normal fluctuations in levels of glucose and other “biomarkers” of health or disease, Wilkins said.
“Horses are a prey species, so they have to be able to get on their feet and run pretty quickly after birth,” she said. “The older and slower I get, the harder it is to approach them. You spend a lot of time on your knees dealing with them, and they can kick. I get bruises all over my body during foaling season and I have no idea where they’re from because I’m focused on what I’m doing.”Add a very protective mother to the equation, and the task gets even trickier.
“Figuring out a way to keep mom from pulling the IV lines out and getting upset when you’re between her and the baby, that takes some doing,” Wilkins said. “The mothers don’t sleep; they don’t lie down; they don’t rest. They’re on their feet with their heads hanging over their babies most of the time. So it’s tough for them.”
If a foal needs surgery, the medical staff will sedate the mom until the foal is back at her side.
Wilkins’ patients may be the progeny of racehorses or performance horses, but many are also just people’s pets, she said. The cost of care can be high, so owners with a strong economic or emotional incentive are most likely to bring a critically ill foal to the hospital.
Despite the many challenges, Wilkins loves the work.
“Foals are just wonderful, wonderful creatures,” she said. “I can’t imagine working with anything else in my life.”

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
