Rob Costello
Editor’s note: The following article is the fourth and final article in a series discussing electrolyte formulation and function in calves. From a clinical evaluation standpoint, it’s fairly easy to gain insights into an animal’s acid-base status from a blood sample.

Electrolytes: Alkalinizing agents

August 25, 2011
Rob Costello
Editor’s note: The following article is the third in a series discussing electrolyte formulation and function in calves. Click here to read the first part, and click here to read the second in the series. Earlier in this series, we saw that strong ions fully dissociate from other substances when they dissolve in water. This dissociation not only affects the electrolyte solution being fed to the calf, it also has profound effects within the animal itself.

Electrolytes: The role of water in acid-base regulation

Rob Costello
Editor’s note: The following article is the first in a series discussing electrolyte formulation and function in calves. Electrolyte comparisons show up in articles and publications from time to time, and are typically based on information found on the label of each product. Although probably unintentional, these comparisons usually contain a fair amount of incorrect or misleading information. These profiles may be convenient and are intended to be informative, but caution needs to be exercised when using these comparisons. To begin, the product profiles in these comparisons use values calculated from the actual numbers of molecules of the different ingredients that make up each electrolyte product. What?!
