Using Missy's Bucket
The main Trace minerals in Missy’s Bucket that you want to avoid in large amounts elsewhere are Selenium and Iodine, both of which could make your horse sick if overdosed.

I usually recommend the following feeds as carriers for supplements. These feeds can be increased if you feel your horse needs more energy or if you want to increase body condition (weight), and grass and hay are just not cutting it.
Maxisoy – Low GI super fibre pellets. Must be soaked (5-10 mins) in 4 times its weight in water, for example, for every cup of pellets, soak with 4 cups of water. I often start with 1-2 cups/day (dry weight)
Chaff or Hay Cubes, fed according to your horse's total forage needs.

A common diet for the average 500kg horse may look like:
- Good quality pasture and hay – preferably native species or unimproved.
- Missy’s Bucket Gut Plus Powder (2 scoops) 75g
- Plain white salt – 60g/day, more on hot days or if sweating for long periods.
Always mix powdered supplements with a DAMP feed to reduce sifting and avoid inhaling powders.
Extra salt is necessary to maintain sodium levels within the body and horse feed is often lacking in sodium. This is important to keep the electrolytes balanced and is particularly necessary in hot weather or when your horse is sweating during exercise. For the average sized horse feed two tablespoon (60g) of plain table salt per day. Add another tablespoon for every hour of sweating work or on very hot days where the horse is sweating in the paddock. Sodium deficiency can show up as dehydration, poor exercise tolerance, muscle fatigue and colic.
Feeding my horse
There are basically two ways you can go about answering this question. 1) – you can make an educated guess and supplement the most commonly deficient minerals or 2) – you can test your forage (hay and pasture) to be 100% sure.
The first and most accurate way to determine what your horse needs nutritionally is to send samples of your hay and pasture to the lab for analysis, then you can balance the diet properly according to the results. How do you know what your horse needs and in what amounts if you don’t know what his or her current intake is?
Minerals are broken down into classes of ‘Trace’ meaning they are only present in tiny amounts, (they are nonetheless very important) and ‘Major’ Minerals.
TRACE MINERALS – The two most commonly deficient trace minerals are Copper and Zinc, followed by Selenium (mainly in the south eastern region of Aus). We can generally bank on a predictable level of supplementation for these three traces. Iodine also gets a look in here and it’s often good to supplement an ‘insurance’ level of this one too.
Missy’s Bucket Mineral Mix has been formulated to supply these most commonly deficient trace minerals, it also includes some important amino acids, vitamins and biotin which has been shown to help hoof health.
I specifically developed Missy’s Bucket for people who were not in a position to test their forage. It’s an excellent value, average or educated guess trace mineral mix. In my opinion, unless you’ve actually tested the forage and balanced your horse's diet from scratch, EVERY horse should be on Missy’s Bucket!
MAJOR MINERALS – For the Major minerals, we often need to add Magnesium, Calcium and Phosphorus. The Major mineral however, are very difficult to guess at, as the quantity that is needed can vary widely and is dependent on many factors, also it’s often the ratio of minerals that is more important than the amount. For example we know that too much phosphorus in relation to calcium can cause bone pathology (big head) so blindly supplementing the major minerals is generally not a good idea, you can sometimes make the problems worse if you don’t know the ratio’s!
Missy’s Bucket does not contain any Major minerals for this reason.
MAGNESIUM – The one exception to this would be Magnesium. Magnesium is very commonly deficient and it’s generally regarded as being a safe one to supplement in low levels. Magnesium Oxide is usually the form I recommend; you can find it in the SHOP. If buying elsewhere, ensure it’s Australian mined, often the cheaper imported forms can be VERY high in Iron which we now know to be toxic to horses in high levels.
Where possible try and source good quality plain grass or meadow hay. Avoid hays such as improved rye, clover or hays that have been grown specifically for cattle (milk and meat production). These improved pasture species often result in hay that is very high in sugar, not at all good for your horse, especially if you have a horse prone to Laminitis and hoof problems. Native pasture is best if you can find it!
If your horse has limited access to green pasture or if the pasture has dried out for long periods then it’s a good idea to supplement Omega 3’s as hay and dried pasture can be lacking.
You will firstly need to identify the pasture species in your horse paddock to determine how much of it contains oxalates and then you’ll need to determine how much of that particular species your horse is actually eating. Go out and observe your horses whilst grazing in order to get a rough idea.
An average 500kg horse needs around:
40g of calcium/day for maintenance.60g of calcium/day for light work70g of calcium/day for moderate work80g of calcium/day for heavy work
Calcium Carbonate, the most common form of Calcium you’re likely to find at the feed store, is approx. 35-40% calcium. Therefore a horse on maintenance (no work) will need around 100g of calcium carbonate/day to provide 100% of required calcium when the diet consists of 100% oxalate pasture, and so on..
The info above is for demonstration only. There are many variables that need to be considered in this situation and I’d highly recommend testing pasture in this situation if possible.
Oxalates in pasture can also vary according to environmental conditions and growth stages of the plant. They tend to be higher in new growth and in wet weather.
If your horse is grazing oxalate pastures and begins to show signs of shifting lameness, this may be a sign that the calcium levels are too low.
A reasonable place to start could include supplementing with a 2:1 mix of DCP and Calcium Carbonate at 20-40g/day for an average-sized horse. This amount of supplemental calcium may cause palatability problems. Another alternative would be to feed 3kg/day of lucerne hay.
Recent research has proven that Iron is toxic to horses when fed in excess, and I can tell you without a doubt that in many horse diets it’s ALREADY IN EXCESS AND APPROACHING TOXIC LEVELS! (Just one of the perks of carrying out regular pasture tests). Check feed labels and mineral supplement labels, if it has added Iron don’t touch it!
