Biozest: improve milk production

Biozest is a NZ pasture spray that improves pasture growth, quality and resilience. In dairy farming, as well as sheep and beef farms, the improved phenypropanoid and soluble sugar content in treated pasture means that Biozest treated pasture is more easily converted to valuable meat and milk instead of polluting waste products such as urea and methane.

Proof of Concept

Sustainably Increases Farm Profits

Biozest helps plants naturally resist stress or damage and deliver higher crop/pasture quality and yield.  Biozest works by eliciting and sustaining plant defence and stress tolerance systems which drive production of a range of bioactive molecules (phenylpropanoids).

Palatability + Productivity

= Less Waste + More Profit

In dairy farming as well as sheep and beef farms the improved phenylpropanoid and soluble sugar content means that Biozest treated pasture is more easily converted to valuable meat and milk instead of polluting waste products such as urea and methane.

Tripple Bottom Line Profit

1. Potential $1000 per hectare potential  increase in net operating profit

2. Reduction of urea loading and greenhouse emissions

3. Supports New Zealand's clean green image and the future of sustainable farming.

Inefficient Stock Digestive System

The Biozest System

Biozest improve milk production, reduce urea discharge

The Challenge

Ruminants do not efficiently convert pasture into milk and meat.


Ruminants discharge damaging urea and methane.


Chemical fertilisers are inefficient and leach to land and water.

Ruminant animals are inefficient converters of pasture protein (nitrogen) to food. The feed conversion efficiency of dairy cows or conversion of feed protein nitrogen into milk or meat is, on average, only 25% (75% is wasted as urea).


Fermentation of  pasture cellulose is slow. To efficiently convert pasture protein to milk or meat this energy release needs to be much faster. The imbalance in the energy supply system leads to waste of energy as methane.

Biozest: grow better pasture

The Opportunity

Increasing the efficiency of ruminant animals’ conversion of pasture into milk or meat will increase farming productivity and reduce waste.


A small decrease in urea excretion and methane eructation has a huge benefit in abating greenhouse gas liabilities

A small lift in conversion of pasture protein nitrogen (from 25% to 27.5% or a 2.5% increase) can deliver a 10% increase in farm productivity.


Nitrous oxide (from Urea) has 298 times the global warming potential per unit weight than carbon dioxide. Methane has 25 times more impact per unit weight than carbon dioxide as a greenhouse gas.


Biologically derived nutrients can further increase pasture growth and productivity.

Biozest improves pasture growth

Biozest - The solution

When ruminants are fed or graze Biozest treated pasture, the higher phenylpropanoid and soluble sugar content in treated pasture improves the conversion of pasture protein into meat and milk instead of urea and methane.

Plants, including pasture, have receptors on their surfaces. These receptors monitor for pest, disease or environmental (such as cold, salinity and light) stress. If the receptors sense stress they trigger the production of beneficial metabolites in plants and pasture.


The molecular compounds in Biozest can “trick” the receptors into reacting as though they are being attacked by pests and disease or stressed by environmental changes. The receptor reacts and induces the pasture to produce metabolites (phenylpropanoids) to ward off the perceived pest, disease or environmental stress.


The phenylpropanoids strengthen the pasture which enables pasture to reach its full productive potential including increasing soluble sugars (Brix). Biozest application therefore improves pasture productivity and palatability.


Phenylpropanoids in plants can protect proteins from degradation and improve the efficiency of conversion of plant protein to animal protein (meat and milk).  Biozest improves dairy feed quality and increases feed efficiency resulting in increased  dairy milk production and meat production without the use of feed supplements or feed additives or excessive use of fertilisers.

Instructions for Use

Fill sprayer tank with water. Shake Biozest container several times to reconstitute content. Add Biozest  & rinse container into tank. Agitate thoroughly before spraying. Best sprayed after pesticide application. Do not mix with pesticides or organic nutrients.


Dairy pasture: Use 1 litre of Biozest (in 50 to 500 litres of water) per hectare. Initial Treatment 2 X sprays applications close together (3 to 5 days apart)

Follow on treatment - Spray 1 X 1 Litre per hectare after grazing (3 to 5 days after grazing)


Dry Stock farm and Turf : Spray 1 X 1 Litre per hectare in spring, summer, autumn and winter.

If treating stock finishing paddocks only - use 1 X 1 Litre per hectare after grazing (3 to 5 days after grazing).
