There are so many things that can affect your horse’s behaviour. One of the big ones I talked about in my ebook ‘My Horse is Lazy, My Horse is Crazy’ is pain! When your horse is in pain, his behaviour will change. And it may become anxious and difficult, or it may be that your […]

Have you ever got the results back from a pasture or hay analysis and been left scratching your head trying to figure out what the numbers mean? Frustrating isn’t it!? That is unless you have a tool (like FeedXL) to interpret the numbers for you. Let me show you what I (Nerida) mean. The analysis below shows the […]
Magnesium oxide. It’s one of those ingredients people love to disagree over, should we use it, shouldn’t we use it, is it bioavailable or not for horses?? Part of this contention is due to the fact that magnesium oxide is a created ingredient… it is cooked in a process called calcination, that reacts magnesite with […]
Anaerobic Fungi! These little critters live in our horses’ hindguts! And they are responsible for an estimated 30 to 40% of the fibre fermentation that occurs in there! So as well as thinking about how diet might affect our horse’s hindgut bacterial populations we also need to think about how it might affect their anaerobic […]
The last two weeks has seen extreme weather conditions for us in my local area in Australia. In the last 14 days, 7 days have been 40 degrees celsius or higher (104 F +) and of the other 7 days only one was below 37 degrees C (99 F). To make things worse, the nights […]
Comparison of equine dietary iron requirements to iron concentrations of 5,837 hay samples N. Richards and B.D. Nielsen, 2018 Introduction Iron is essential for the production of red blood cells. According to the 2007 Horse NRC, Fe requirements are 50 ppm for growing foals, lactating and pregnant mares, and 40 ppm for all other classes […]
I think it must be a combination of both! Poet and I did an unintentional experiment over our Christmas break that seems to show that the sunbleaching that occurs in some horses over summer is a combination of sun and sweat. Where we live flies can get bad, so my horses have flymasks on during […]
Q: Does gastric ulcer medication reduce nutrient digestion in horses? Someone asked me this in a recent seminar and it reminded me that when I was studying during my PhD tenure we had looked at the effect of pre-incubating grains in equine stomach fluid on the digestion of starch from those grains. And what we […]
Poet and I (Nerida) headed out a few weeks ago to do some real work mustering sheep (not that we did anything useful, we were just along for the ride!). There were 5 of us on horses, saddled up by 6:30 am and in incredibly steep, rocky, tough (but stunning!) terrain for 6 hours. At various […]
Have you ever wondered how much of an impact the weather has on your horse’s calorie requirement? While it is poorly documented in horses, observation suggests that the environmental conditions a horse is kept in can have a huge impact on their requirement for calories. Here are some of my (Nerida’s) personal observations: Winter 2016 in […]
