I am questioned often about what color I think a mare will produce when crossed with a particular stallion. Most of the time it is pretty straightforward, but I usually have the most difficulty explaining base colors. As much as I enjoy doing coat color calculations, I thought it would be interesting to put together some basics.

Red Factor

Equine base color is either Red or Black. Red is recessive, meaning it takes only one black to cover it up. While this sounds pretty simple, your base coat can have a significant effect on modifier and dilute colors. I will designate Red with a lower case ‘e’ and Black with and uppercase ‘E’.

Each horse gets one gene from each parent, giving them a pair that decides what their base color is. So, ‘ee’ would be red and ‘Ee’ or ‘EE’ would be black. UC Davis’ VGL website lists a rare ‘ea’ gene also but does not state if it affects the shade of red exhibited.

A Red parent will always give a Red gene, while a Black parent with heterozygosity for Black (one E and one e) would produce the ‘e’ gene 50% of the time. A parent with homozygosity for Black, or ‘EE’, will always produce a Black foal.

We can all agree that black horses are always black, though they do sun fade in the summer. But Red horses are a different story because red color can vary even between family members. Some have flaxen manes, some show sooty shades, some have honey colored highlights, some are copper or mahogany, but they are all Red genetically. Eventually, perhaps the changes of tone in the red hair can be better explained with genetic markers.

Red Factor is heavily affected by the Agouti gene, which creates Bay on Black base coat horses. I will address Agouti in the next article, but I have linked to a journal article from 2016 that suggests that Red Factor and Agouti may have an effect on equine behavior.

Has anyone had any crazy colored red horses?

There is a 2018 filly by Gotta Be Free that is a sooty red and has varied shading in her coat, including a black spot with white hair in it. Really interested to see what she looks like when she sheds again!

Riding Apps: Equilab

By Joanna ByrneScreenshot_20180819-223714_Google Play Store

Finding a good app to track speed and distance while riding has been an effort of trial and error, fortunately as smartphones have gotten more advanced the options have gotten better. One of the apps that I have been trying out Equilab by Schvung Ride AB. It is pretty in depth, and has lots of options, and is available on Android and iPhone.

Profiles

Screenshot_20180820-005237_EquilabRider profile is pretty straightforward, with name, gender, and weight. A profile picture can be added, and that pretty well sums it up. Nicely if you go into settings, you can link it to your Google Fit account, which is handy because I can tell you that Google Fit usually thinks I’m riding a bicycle when I ride my horse.Screenshot_20180819-224542_Equilab

Horse profiles are a little more in-depth than rider profiles. You can edit the photo, registered name, nickname, main discipline, type, breed, weight, and date of birth, as well as ad multiple riders to each horse. For each horse, there is a Trends tab where you can swipe through several graphs of information over weekly and monthly windows.

In the Stable Profile, found on the rider page, you can add your stable and the GPS location. Unfortunately, this seems to be a buggy part of the program, and I could not get it to cooperate to take screenshots of the options. After a few weeks of use, this seems to be the only buggy area in the app.

The homepage is pretty straightforward, showing a location map and which horse you are currently riding. You can quickly change the horse, and present riding type, before pressing start. If you forget to do either of those, you can always change the information after your ride. Once you are done, it asks about rider and horse performance, what kind of footing you rode on, and gives you a place to make notes about your ride.

TrendsScreenshot_20180819-231057_Equilab

Here you will find data on everything documented with each ride, broken down into weekly and monthly charts. Your input and the GPS data are grouped in graphs showing the trends in your riding habits, which can be very informative on your good and bad habits.Screenshot_20180819-224922_Equilab

Under Trends I like the Turns page because I know I spend more time on one side than the other. This gives a break-down of how much time you spend turning each direction. It has made me much more aware when I’m riding, and I am making a conscious effort to keep track of it. It also charts footing, speed, distance, and performance ratings.

If you scroll to the bottom of trends you find a tab for All Trainings for ride history, Energy Consumption for calculated energy burned and required calories to maintain, and Compare which matches your training trends to different disciplines.

FriendsScreenshot_20180820-014901_Equilab

The app has a Friends menu that works like a news feed for you and your horse riding friends. Since it’s just me using it, I don’t have anyone else on my riding feed. I think this would be most useful for riders that stable together because you can see the ride notes, and leave comments, which leaves the opportunity for information exchange about horses, footing and other conditions.

My Rating

I rate the app a 4 of 5, only because of the bug in the Stable Profile option. Everything works smoothly, it does not shut down when you open another app, and it has lots of options. I’m sure there are some things that users could suggest being changed, reading the app reviews shows that. Overall though I think this is a great app and I will keep using it, although I am known for running multiple apps at once to see which performs better. You can find Equilab in the Google Play store, Apple Store or check out their webpage: https://equilab.horse/

Leg Wraps: Richland Boots

By Joanna Byrne

I have never been crazy about sports medicine boots. Since my first horse was allergic to neoprene, I avoided it, even when lined with something. I quickly drifted toward polo wraps, and have used them successfully for about eighteen years. My biggest concern with polos is that they offer minimal impact protection for horses that over reach or crossfire. However, they have been adequate protection and budget friendly for the horses I have that tear through wraps regularly.

20180802_203350

I have looked for several years at padding options that go under polos, and finally purchased a set of Richland boots. Here I will list my impressions of them through the process.

 

Round 1

Initially, I was surprised at how light they were. I had expected them to feel heavier, despite knowing their actual weight.

I attempted to fit them to Leonidas (Primoris Prognatus), using vet wrap as I do not yet have a set of Saratoga wraps. Fortunately, he is more patient with me than I was with the boots. In attempting to get them situated to determine if they needed trimming, I managed to tear one of them… Not the best first impression, but I reminded myself they were second-hand new and had been in storage for a few years.20180802_203947

I decided they were a project for another day and rode for what little daylight was left without them.

Round 2

After trimming the torn front ones down where I should have cut them to start with, and leaving my Richland boots rolled up and wrapped in vet wrap for a few days, they were easier to manage and successfully set them up on my boy’s front legs. I did not finish trimming them yet since they were close to fitting. I secured them with vet wrap, then added a standing style polo over them in the front because I was planning on doing some work that would have a high risk of my brand new boots getting torn up. Polos are hands down too bulky over them, I’ll be pulling out some track wraps until I get Saratoga wraps.

First Impressions

20180806_214807

Leonidas was not fussy about them like he is with boots that have a noticeable weight to them, and he was more comfortable crossing over on his spins. After we rode, the Richland boots were soft and had shaped nicely to his legs. I got a good idea of where I need to trim them now that they are leg-shaped.

Round 3

I trimmed the fronts, the backs were perfect, and we had a nice work on fence day. After the ride, I decided that the fronts will need a little more trimming, maybe a half inch, and should be perfect. I am quite pleased with them, they did not pick up a lot of dirt, and were easy to clean.

I am satisfied with the Richland boots for the short term and will give my long-term impressions of them after I use them for a while. Time is the best determination of value for the dollar spent.
