I have always wondered which supplements are the best choice for my forage, but never got around to collecting pasture and hay samples for analysis. Well, I actually did it this summer! I used Equi-Analytical for my hay and pasture testing. I am more concerned with my pasture since my horses spend most of the year on grass. For this analysis I used the following service:
|Equi-Tech – combines high tech near infrared and plasma spectroscopy for a complete nutritional profile. By utilizing this progressive technology, lab efficiency is maximized enabling us to offer you a complete hay or pasture analysis at a reduced cost. Includes moisture, dry matter, digestible energy, crude protein, estimated lysine, acid detergent fiber, neutral detergent fiber, lignin, Ethanol Soluble Carbohydrates (ESC), Water Soluble Carbohydrates (WSC), starch, non fiber carbohydrates (NFC), fat, ash, calcium, phosphorus, magnesium, potassium, sodium, iron, zinc, copper, manganese, molybdenum.
Best use – best dollar value for frequent analysis of hay or pasture when a comprehensive profile is desired.
plus I added selenium analysis. I have been told that Southern Illinois is low in Selenium so I wanted to see if that was true for my pasture. Well it was not true! I have plenty of selenium, way too much iron, and too little copper and zinc. The ideal ratio of Iron:Copper:Zinc:Manganese is between 10:1:3:3 to 4:1:3:3. mine is 30:1:4:7
Well this is a problem! Why should I be concerned that the Iron is over 10? Well, Iron overload is linked to increased insulin resistance, arthritis, increased tendon/ligament problems, bleached or dull coat, ongoing thrush, and poor hoof quality. You can take a look at the nutrient table from FeedXL below.
I then ran my hay analysis hoping for a different outcome. Please note I did not pay for the selenium to be run in this analysis. It came out with a ratio or 30:1:4:27 It is from my area (Southern Illinois), but a different location from my farm. It also has high Iron, in addition to high Manganese.
