StockBrew® FAQ

What is different about StockBrew?

BioBrew is a fresh product containing very high numbers of live, active probiotic microbes and the beneficial metabolites (butyric acid, acetic acid, lactic acid, etc.) these microbes produce. Unlike freeze-dried products, our microbes get to work from the moment they are administered to your animals. Our microbes are selected to survive the challenges of the ruminant digestive system, including stomach acid and bile salts.

Our products are regularly tested for viability and other quality characteristics by Lincoln University.

How long does StockBrew stay fresh?

We recommend using BioBrew within 30 days of opening.

How should I store StockBrew?

Keep containers tightly capped and out of direct sunlight. Shed conditions are appropriate for storage.

What’s that stuff at the bottom of the container?

The accumulated material often found at the bottom of containers is rich in microbes and should not be wasted! Invert container before use.

Rinse containers and provide rinse water to stock.

What is in StockBrew?

Water, feed-grade molasses (conventional product only), organic raw sugar, GRAS (Generally Regarded As Safe) microbial culture that includes lactic acid bacteria and yeasts, kelp and either dolomite or lime.

The microbes in BioBrew convert the sugars we provide into more live microbes and the important and beneficial metabolites, such as organic acids, that the microbes produce. There is virtually no sugar at the time of bottling

What do I do with all of the empty containers?

Deposit at your local recycling station.

How do I order StockBrew?

You can purchase StockBrew through our online store!


Is BioBrew suitable for use in cows, sheep, deer, pigs, chickens, goats, alpacas, etc?

BioBrew is optimised for use in ruminant production animals but is safe to use in all species of production animals at all stages of development.

How should I administer StockBrew to my stock?

BioBrew may be added to feed, stock water, or direct drenched.

BioBrew should be introduced to feed just before it is distributed to stock and should not be allowed to dry out before it is ingested.

BioBrew may be introduced to stock water with an in-line dispenser such as a dosatron, via a trough dispenser, or simply poured into troughs as stock move into a new paddock.

BioBrew may be added to milk/milk substitute for young animals.

I use magnesium chloride in my dosatron. Will that harm the microbes in StockBrew?

Many farmers use BioBrew in combination with inputs such as magnesium chloride or trace elements that are somewhat harsh for microbes and still obtain very good results.

We recommend that BioBrew be added to the dosatron barrel last, i.e., at maximum dilution, to minimize the effect of other additives.

Some farmers have adopted the practice of filling the dosatron barrel in the morning with magnesium chloride and other inputs and waiting until the afternoon to add BioBrew and top up the barrel with water to further improve the dilution effect. Some farmers have also chosen alternative inputs such as magnesium sulphate that are somewhat gentler on microbial life.

Is it possible to overdose my stock with StockBrew?

BioBrew is completely non-toxic and causes no withholding for milk or meat. Doses far in excess of recommended doses will not cause any harmful effects.
