[QUOTE="Nesikep, post: 1128717, member: 9096"] Here's what I'd like to see No Iron? No Cobalt? No Iodine?... I could see omitting the Iron perhaps, but cobalt is essential for B vitamin synthesis in the rumen, and is hard to over-do, my mix has 100ppm Cobalt. Iodine is another important one, and I haven't heard of iodine poisoning, My mix has 500 ppm. As for Iron, my mix has 7500mg/kg (or ppm), and it also interferes with copper, and I would have less if I had the choice. What I see with this, is that it's going to get expensive, and quick, and possibly not be everything you need. Why expensive? well, Salt is usually the motivating, and limiting factor in mineral consumption with cows, 10% salt will mean they will lick this not for it's mineral, but to try and get enough salt out of it. The Calcium/Phosphorus ratio is a rather local thing, but phosphorus is also one of the expensive ingredients, so they can sell a cheaper product if they leave some P out of it... It's up to you to know if it has what you need... I don't need calcium.. I got TONS.. I have NO phosphorus though, my mineral is either 6Ca, 12P, or 9/18... the second is more expensive by a fair bit, and is otherwise fairly similar except for less selenium... Cows don't know what they need, except for water, food, and salt... They kinda know they need *something* when they're low on phosphorus, and will eat rocks, wood, bones, etc, but they won't usually pick out the right stuff to chew on. With my mix, I put about 25% mineral mix, and 75% salt.. with that ratio, they get FAR more mineral than even the 'complete' mineral salt blocks. Most importantly, 'mineral blocks' do not usually contain calcium and phosphorus either. I can't tell you that Ultralyx is wrong for you, I can certainly say it's terribly wrong for me, and could see improvements to it that would probably be good for most locations. I'd say get a blood test done, I think I paid about $50, and it was the most worthwhile money I've ever spent at the vet clinic. You need a special test tube and needle to draw the blood, your vet should just give you a couple, and then when you are AI'ing your cows, it's pretty easy to find that mammary vein and get a sample. Then you have a really good starting point for chosing your minerals. Lastly, Oxide forms of minerals are always the least soluble, thus the least usable. That mix uses Magnesium Oxide, which won't be much good (though magnesium is more soluble in any form than many other minerals like copper, iron, etc), thus you need a ton of it, Dollars to doughnuts if it were magnesium sulfate or magnesium phosphate, it's usability would triple, or better. My mix has 0.5% Magnesium, don't know in what form though.. I have never had problems with grass tetany and haven't heard of it in this area. [/QUOTE]
