Can you post a tag? With all the wording. Not just the specs. I'm guessing they labeled for intake 1/3 of what they actually eat so you get 9mg but the tag say max 3?

The US regulations cover national products and custom products. Any products that's labeled intake exceeds 3mg Se/h/d would be illegal. Per head per day is the key here. You have to take the ppm (same as mg/kg) then multiple by the labeled intake (in kilograms not pounds or ounces) that number...

Nutritionist here. Someone else hinted at the reason later in the thread. The reason is Se is regulated by the US government which says cattle cannot consume more than 3 mg of Se/h/d or 0.3 ppm on a dietary basis. The label is basically saying "hey don't feed any more selenium or what you are...

Technical correction here. The term "Chelated" refers to a type of chemical bond between the metal & an organic molecule. This is an "umbrella term" for organic trace minerals. There are many types of organic trace minerals on market and the most well known would be Availa sold by Zinpro. Those...

Quality free choice mineral has a place on pretty much anyone's place. Multmin has a place- but just on pretty much no one's place. That's a big over simplicition. But on the majority of ranches I've see use it with success weren't using a high quality mineral at the time & would likely have...

In commercial supplements (things you buy from a feed company) like liquid feed, cake, mineral, or tubs. The feed analysis numbers on the tag are "as fed". So if the protein in a cake or liquid is listed at 25% and you feed 1 pound the cattle get 0.25 lbs of protein. Protein in feedstuffs (stuff...

So a lot going on here. I'll try to answer everything. But this is a somewhat complicated discussion... First biomos (Saccharomyces cerevisiae) and it's competitive products. I don't believe these products improve fiber digestion. I've seen some research where they improve feed efficiency & I...

Depending on how many cattle you own superior livestock auction would be a good market for NHTC. I'm not a huge NHTC fan, I think often you give up too much performance. Cow-calf guys probably give up 20 pounds. Feedlots probably $100/hd advantage. You have to have a pretty good premium to cover...

Replace your current mixer wagon spout with one that has magnets on it. If yours already has one make sure you clean it every day. Easy way to reduce hardware. When I was working at a commercial feedyard after each day the spout would have collected about as much metal as shown in the above...

What are you feeding? And what are you feeding it too?

Corid/monensin don't impact the rumen in similar ways or cocci Corid doesn't impact the rumen like min. But it does kill cocci, unlike mon. Monensin prevents the reproduction of cocci, & changes the rumen increasing feed efficiency. So it takes 28 days to work (that's the life cycle of cocci)...

As with any subject that has been study I'm sure there is more than one study out there. But here is one where they just randomly ate it (hope this link works it's a pdf). You can Google "cafeteria mineral cattle" and start reading the studies...

That would be correct. Basic copper chloride, sometimes called hydroxy copper under the trade name Intellibond sold by micronutrients would be a big supplier of it to feed companies. It will preform similar to the amino acid complexes at a cost only slightly higher than copper sulfate. There...

They already did the research on this years ago. Cattle have no nutritional wisdom except for salt.

What source of copper are they using? That's an insanely high level of copper.

Can you expand on what your asking?

You can feed quite a bit of corn every day to cows and have minimal impact on rumen pH/ forage digestion/no risk of acidosis. Rule of thumb is up to 1/2 of 1% of BW. So a 1400 pound cow could get 7 pounds of corn a day without issues.

It's odd that every time a feed company publishes an "informative" article on a new technology/idea they never mention all the instances where it didn't do a dang thing.

I've always been a fan of the protein+mineral products companies make. I think they are as convenient as tubs but typically cheaper/hd/d.

Bioavailability is relative, it's not a standard figure. In diets without mineral antagonists sulfates will be just fine. The animal will absorb enough mineral & won't have issues. But if you add a bunch of heavy metals like iron & molybdenum or certain other minerals like sulfur & now sulfates...
