Reduce Oxidative Stress, Improve Cow Health and Performance

AgriSea Fortress+ Dairy is a scientifically proven liquid animal nutrition supplement developed specifically for dairy farms. Designed in collaboration with Lincoln University and made and tested in New Zealand, Fortress+ Dairy helps reduce oxidative and physiological stress in dairy cows while increasing rumen function, supporting healthier animals, stronger calves and improving milk production.

Oxidative stress around calving places significant pressure on cow health, body condition and immune function. Fortress+ Dairy works by improving rumen fermentability and increasing the production of volatile fatty acids, delivering more available energy when cows need it most. Using just 5ml per cow per day, it supports higher body condition scores (BCS), improves energy levels, reduces oxidative and metabolic stress before and after calving, enhances antioxidant transfer from cow to calf, and improves feed conversion on diverse pastures.

Healthier, less stressed cows are more resilient, less prone to disease and incur fewer animal health and veterinary costs. Trials also show an average 18% reduction in urinary nitrogen excretion, helping reduce your farm's environmental impact.

Application Methods

Fortress+ Dairy can be applied in multiple ways to suit the scale of your growing operation. Fine filtration will ensure no clogged lines or spray nozzles. Need help? Contact your local AgriSea approved applicator.

What our customers say

“We've faced challenges with our 380 predominantly Friesian mix herd, including a bad case of high levels of milk urea due to fast-growing pasture. Following advice from an independent advisor, we turned to AgriSea Fortress+ Dairy, recognising its potential to enhance gut microbes. One cow suffered from a more severe case of high levels of milk urea compared to others in the herd and was drenched with Fortress+ Dairy, then treated with 20ml daily for three days. Remarkably, the cow's condition improved significantly, returning to the herd. I watched the cows and saw an overall herd improvement. I've noticed an increase in milk production and they were doing better with the high protein diet. I'm now dosing at 5ml per day in the water dispenser.”

Frequently Asked Questions

Who is Fortress+ Dairy designed for?

Fortress+ Dairy is formulated specifically for dairy cows and calves although the benefits are also being noticed in drystock beef.

Is it scientifically proven?

Yes. Fortress+ Dairy was developed through collaborative research with Lincoln University and has been rigorously tested under New Zealand dairy conditions using traditional scientific research methods.

How is Fortress+ Dairy different from AgriSea Animal Nutrition?

Fortress+ Dairy is more complex and effective than our Animal Nutrition product. The latter is made from native brown kelp seaweed only, whereas Fortress+ Dairy contains this powerful seaweed plus a variety of terrestrial plant extracts. This improves its efficacy by increasing the amount, and diversity, of bioactive molecules that are present. It is lighter in colour than AgriSea Animal Nutrition (due to the light coloured plant extracts) but this has no bearing on how effective it is.

Does it support environmental outcomes?

Yes. Trials show reduced urinary nitrogen excretion, helping minimise nitrogen loss to groundwater.

Is it easy to use?

Yes. It is a liquid supplement with a very low daily dose rate and integrates easily into existing feeding systems.
