Mineral article in 2008 Winter Cattle Journal

Faster horses

Well-known member
Just wanted to reprint a couple highlights from the findings of the University of Minnesota Beef Team:

"Mineral nutrition is largely ignored and it is likely a greater factor in cow and calf performance that perceived."

And--
"Simmental, Limousin, Charolais and Maine-Anjou cattle may have 50% greater copper requirements."

Nicky, there is no link but I googled University of Minnesota, Alfredo DiCostanzo and found some interesting information. For one thing, there is a page with the NRC nutrition requirements of beef cows in different stages of pregnancy, so I am going to post that link here. Hopefully a lot of people will take the time to look at it. It's like on the third page.

OH, I FOUND IT. Here is the link:

Hope this helps. It's a bit technical, he does talk about tie-ups and grass tetnany.

One of our customers called last night as he had a 2-year old heifer that was very loose, with blood in the manure. As we talked he told me that for years, since he has been on our mineral program he has to do virtually no doctoring. That is something that you will find when you are on a mineral program. ('Program' meaning that mineral is available free-choice every day; not hit and miss.)

We decided his heifer had just had a good shot of protein and was experiencing some acidicosis as a result. She wasn't sick and wasn't off feed.

Had forage and hay tested then bleed a few cows, Blood matched the same mineral loss as the forage so have a custom mix mineral.
Have to make sure the ewes can not get any where near the cows mineral feeders. Enough copper to tip them over.
