Mineral Nutrition of Dairy Cattle

The article carries good information. My question to the author is which is the best form of supplementing these trace minerals as we have inorganic and organic form in the market.

The theme of the paper is certainly useful, however the data is clearly out of date. Why cite NRC standards from 1988 when NRC published new guidelines in 2001? Don Sanders D.V.M., Dip ACT, PAS Associate Professor, Clinical The Ohio State University Large Animal Field Service Marysville, OH

The level of Na and K seems to be very high and increase concentrate ration cost. We fed Cameroon grass (tall grass, pasto elefante) as a forage for dairy cows (25 lts/day milk) in a very hot and humid environment. Are these levels recomended to use? (0,4 -0,67% Na 1,5% K). How can I supply K since my mineral salt does not content enough K? Na content of the forage is about 0,01% (by reference) and calcium 0,12% (by laboratory). Are these values similar to your forage? Thanks. Luis Gulino

I am unable to read the tables. Their print is too small.

You must click on the table, and when the new window appear, you must click on the magnifying glass or the icon to enlarge the table, which will appear over the image. You will be able to see the numbers perfectly. Engormix.com Staff

This article is useful no doubt on it. But I would to ask a to the author, which form is easily to the animals whether it is inorganic and/or organic?

Hi This means that they need to be dissolved in liquid (water) in order for them to be available to the body. Mineral deficiencies are generally due to a nutrient poor diet or an inability to absorb ingested minerals. Calcium is the most abundant mineral in the body. Instead of first respecting the natural alchemy of minerals and health,and restoring the optimal of the body it employs powerful but inappropriate drugs to treat disease. Thanks...
