AgriSea for Cows and Calves
Seaweed-based nutrition designed to support stronger calves, healthier cows and more resilient dairy and beef systems from birth through to peak production.
AgriSea's seaweed-based nutrition products have been helping New Zealand farmers achieve measurable improvements with their dairy and beef cattle for three decades. Our proven formulations support every stage of life – discover exactly what AgriSea can do for your herd.
Cattle face significant nutritional and health challenges throughout their productive lives – from the stress of calving and transition periods to the demands of peak lactation or rapid growth. Common on-farm challenges such as milk fever, down cows, high somatic cell counts, empty rates, grass staggers and mastitis often reflect underlying metabolic and mineral imbalances. AgriSea provides comprehensive nutritional support using sustainably harvested New Zealand brown kelp seaweed (Ecklonia radiata), processed using our proprietary cold-brewing fermentation technology to preserve vital nutrients and bioactive compounds.
Our seaweed extracts contain vital minerals and trace elements in bioavailable forms, natural growth factors, amino acids, vitamins, and unique polysaccharides that support immune function, gut health, and overall vitality. When you supplement with AgriSea, you're supporting immune resilience, metabolic balance and mineral status – key foundations for maintaining udder health, stable somatic cell counts and consistent milk quality throughout lactation.
Research also indicates improved nitrogen efficiency and reduced urinary nitrogen excretion, contributing to more environmentally resilient dairy and beef systems.
Whether you're managing a commercial dairy herd, rearing replacement calves, or finishing cattle for beef, AgriSea offers targeted nutritional support backed by research, proven in practice, and trusted by farmers around the world.

Frequently asked questions
Common questions about using AgriSea with cows and calves
How does AgriSea benefit cows and calves?
AgriSea provides natural seaweed nutrition that enhances immune function, improves gut health, supports milk production, and promotes overall vitality. The bioactive compounds in seaweed - including minerals, amino acids, and natural growth factors - work synergistically to optimise cow health and productivity. For calves, AgriSea supports rapid healthy growth, stronger immune systems, and better feed conversion efficiency during critical development phases.
When should I start supplementing calves with AgriSea?
AgriSea can be introduced from birth onwards. Many farmers mix it into colostrum or milk replacer from day one to support early immune development and gut health. Continue through milk feeding and transition to solid feed, as this early supplementation establishes strong foundations for lifelong health and productivity. These critical early weeks benefit enormously from the immune-supporting compounds in seaweed.
Can AgriSea reduce mastitis and somatic cell counts?
Yes, research and on-farm experience consistently show that AgriSea supplementation helps reduce mastitis incidence and lower somatic cell counts. The natural anti-inflammatory compounds and immune-supporting nutrients in seaweed help cows maintain healthier udders and fight infections more effectively. Many dairy farmers report substantial reductions in clinical mastitis cases after introducing AgriSea to their feeding programmes.
Will AgriSea help improve reproductive performance?
Yes, many farmers report improved reproductive outcomes including better conception rates, reduced calving intervals, and easier calvings. The comprehensive mineral profile and bioactive compounds in seaweed support optimal reproductive function, egg quality, embryo development, and uterine health. Better cow body condition and reduced metabolic stress also contribute to improved fertility and successful pregnancies.
Can I use AgriSea alongside other supplements and medications?
Yes, AgriSea is a natural nutritional supplement that works well alongside conventional supplements, minerals and medications. There are no known interactions or withdrawal periods. Many farmers find they can reduce reliance on some supplements as the comprehensive nutrition in seaweed addresses multiple nutritional needs. Always consult your veterinarian about your specific supplement programme and animal health protocols.
How long does it take to see results from AgriSea supplementation?
Results vary depending on the metric, but many farmers report noticeable visual improvements within 2-4 weeks. Coat condition and animal vitality often improve quickly. Reproductive improvements and reduced disease incidence become clearer over 2-3 months. For calves, faster growth rates and better health are often apparent within the first month of supplementation.
Is AgriSea suitable for organic farming operations?
Yes, AgriSea products are made from sustainably harvested New Zealand seaweed using natural cold-brewing fermentation. Many of our products are certified for organic production systems. Check with your certification body and AgriSea Area Field Consultant to ensure the specific products you're interested in meet your organic standards and certification requirements.
