Solutrace Southerner

SPECIFICALLY FORMULATED FOR THE SOUTHLAND REGION

The high rainfall and heavy reliance on crop grazing in this region lead to higher levels of soil ingestion, this causes a number of essential minerals to become bound and excreted. Solutrace Southerner takes care of these problems by supplying a complete balance of eight trace minerals with the key minerals in a non-binding amino acid chelate form. Amino Acid Chelates have a much higher level of bio-availability; absorption is direct to the bloodstream and stored in the muscles. Solutrace Southerner will however also supply some minerals in the non-organic form in order to efficiently feed rumen bacteria as well as utilize liver storage capacity.

HIGHER COPPER – High levels of copper in glycinate form, allows higher blood copper levels.
BETTER SELENIUM AVAILABILITY – 4 mgs of selenium in the glycinate form will give better control of selenium deficiency.
EASY TO USE – Stable dry powder form, high solubility in water, can be drenched, dispensed into drinking water or blended into feeds.

What the research shows

A South Island dairy cow study found that complexed zinc, manganese, copper and cobalt supplementation improved milk yield, several reproductive performance measures and copper and vitamin B12 reserves in intensively grazed lactating cows. (DOI: 10.1016/j.anifeedsci.2006.10.006)
A meta-analysis of lactating dairy cow trials found that organic trace mineral supplementation was associated with higher milk production and some fertility-related outcomes across the studies reviewed. (DOI: 10.3168/jds.2010-3058)
A dairy cow study found that added sulphur and molybdenum reduced liver copper reserves, with stronger effects in cows fed a grass silage-based diet, showing how dietary antagonists can affect copper status even when copper is present in the ration. (DOI: 10.3168/jds.2016-12217)

Limits

These studies examine trace mineral supplementation, organic and complexed mineral sources, and the effect of dietary antagonists such as sulphur and molybdenum on copper status. They do not test Solutrace Southerner itself.

Study details and links

What was tested

Dairy cow research covering supplementary trace minerals such as zinc, manganese, copper, cobalt and selenium, including organic and complexed mineral sources. Research also examined how sulphur and molybdenum can interfere with copper status in dairy cow diets.

What was measured

Milk yield, reproductive performance, fertility measures, blood and liver mineral status, copper reserves, vitamin B12 reserves, feed intake, body condition, somatic cell count and selected production measures.

More detail on limits

The research supports broader mineral nutrition principles relevant to trace mineral form, copper status and mineral antagonists, but it should not be read as a direct product trial for Solutrace Southerner.
