Cayenne - A Sabino Roan

Cayenne is an adorable miniature colt that is going to be weaned soon. Up to this past Tuesday, I have been thinking and thinking about his coloring, and trying to figure it out. Just to make things clearer for you, right now he appears to be a chestnut roan sabino.

As a foal, his owner and I thought he would just be a light chestnut with a fair amount of chrome (in the Miniature horse world, this means white or markings). After a bit of maturing we could tell that yes, he will have high lacy stockings on his hind legs, an apron face, and perhaps more. Then, we got to what puzzled me- he appeared to have roaning in his phenotype (appearance)!

Myself being into horse genetics and knowing the coloring of Cayenne's parents, here are some facts.

• Roan is a dominant gene. If a horse has it, it'll show up.
• To get a true roan, one of the parents has to be a roan.
• Neither of Cayenne's parents were a roan.
• Pepper, the late sire, was a buckskin sabino.
• Birdy, Cayenne's dam, is a light solid palomino.

What I didn't remember until last Tuesday was that the sabino gene can include the roan gene (even if it isn't a true roan). Apparently Pepper had seemed roan until he was a yearling, at which time he lost the roaning, but still was sabino. (Not sure if that'd affect much or not though.)

My current hypothesis is that a sabino horse can yield a sabino foal with roaning, even if the parent was a roan-less sabino. I'm still trying to figure out how a different friend got a chestnut roan out of her two solid chestnut Walkers, but perhaps I'll discover the reasoning behind that one later. Or perhaps it was a freak accident, who knows? *shrugs*

To close, if you want to see a picture or few of Cayenne, here're a few from last Tuesday. :)

And walking, which was rare for his energetic little self.

I got an itch, and I just gotta get it!

A "Cast" Horse

If you've been around horse people a lot, but have not been around horses extensively, you've probably heard of  when a horse gets "cast". If you are similar to me, you'll ask what it means multiple occasionthroughout time, but won't quite understand how it happens and why it is so dangerous. If you are even more like me, you may even Google the term, searching for pictures. And, similar to me again, you'll be unsuccessful.

A cast horse is a horse that has its hind legs stuck up against something, ergo not being able roll into a position to stand up. This gets dangerous after the horse has been cast for awhile, for the digestion system doesn't work very well will not in its normal orientation.

Thankfully, I have two pictures to share with you. These may be the only online pictures (for now) of a cast horse ever in history. Unfortunately they're both nasty quality, blurry, and perhaps even slightly warped as I took them with a cell phone camera. Either way, I'll show you them so you can understand the concept of a cast horse.

As you can see, the hind hooves are stuck against the fence. Most often though, a horse
gets cast against a stall, and it isn't so easy to handle as it was for this mare.

Sorry for the lame view, but here you can see it a bit better. You'll also see that there (thankfully)
is room for the hind legs to maneuver around, unlike many cast situations.

Besides colic (when the horse's digestion system isn't working right), there's also danger in getting the horse un-cast. Use whatever safe means you can, but be wary of the horse's hooves as they flail about.

After the horse is un-cast, watch him for awhile. If the horse is eating and acting normal, that's good. If the horse acts like he has a tummy-ache, call your vet. Colic is nothing to shrug off.

A Brief Explanation of Colic

Colic is a very bad and possibly fatal condition a horse can get, and is the leading cause of unnatural death in horses. If you have horses, or a friend does, please read this, and let's keep safety first. =)

Colic is like a bad stomach-ache on a horse. The reason colic is terrible has to do with the tight muscles in the horse's esophagus, preventing the horse from regurgitating food. As such, the food either has to continue onward through the digestion process, or result in rupture or impaction (basically constipation). If the horse is blocked at both ends, this can fairly easily lead to colic.

Naturally, horses are not on the ground without their legs beneath them very often at all. So, being cast puts a horse in an awkward position, and remaining in this position for a prolonged period of time can cause colic. Especially if the horse is rolling and flailing around a lot, trying to free their legs.

As far as colic goes, the main safety is prevention, as well as catching it early on. Depending on how long the horse was cast, watch the horse for any signs of pain near the belly. Some of the possible signs may be a horse having a pained look on his face, looking back at his barrel often, reaching back and biting the skin, and rolling. Of course, every horse is different, so the easiest way to tell if a horse isn't healthy is if he isn't acting normal.

If this has ever happened to one of your horses, feel free to add tips/what you learned below in the comments section. Thanks!

P.S. - Colic can also be caused by a horse rolling around or being cast (see blog post coming soon on November 16), so keep that in mind as well.
