IntelliBond Trace Minerals Series- Digestibility Feature


IntelliBond Trace Minerals Series: Part #6 – DIGESTIBILITY

Trace Minerals and Rumen Microbe Function

  • Weak iconic bonds from sulfates cause dissociation of the metal when exposed to moisture (rumen fluid) and release free metal ions.

  • The free metals have the ability to negatively affect microbe function.

  • It is not the sulfate portion that is harmful to rumen microbes, it’s the free metal ions such as copper and zinc that are highly oxidative and antimicrobial – which is why copper sulfate and zinc sulfate are used as antimicrobial agents in applications such as footbaths.

Microbial Requirements

Sala (1957) found that when rumen fluid was included in an in vitro system, any additional zinc actually decreases cellulose digestion. This indicates that zinc content of the basal diet is likely enough to supply rumen microbes with the zinc needed to maximize cellulose digestion.

Sulfates Reduce Ruminal Digestion

Copper zinc, and manganese sulfate reduced apparent organic matter disappearance (6-7%) compared to no added trace minerals and IntelliBond copper, zinc, and manganese in a 48h in vitro fermentation system (Micronutrients Trial#2019R131CACZM, 2019).
