Biozest: a Transformational Technology

Presented at the NZBio Conference 2014


The concentration of urea in one urine patch is equivalent to a

farmer applying 1 ton of urea per hectare.

A dairy cow urinates on average 10 times a day a total of 25 litres.


This means that, in one year, milking cows produce 9125 litres of this resource.

We have 4.96 million milking cows in New Zealand.

Therefore, the dairy sector alone produces 45,260 million of litres of this resource: enough to fill 20 thousand Olympic size swimming pools.


If we can convert just one fifth of this urea nitrogen to protein we will double our farm productivity

and address the global food security issue as well as abate our greenhouse gas liability.


We have a biological system, the knowledge and the technology to achieve this transformational goal!

The Resource

Biozest improves ruminant digestion

In ruminant animals, only 20 to 25% of the consumed pasture protein is converted to milk and meat, 75% is excreted as urea.


This under-performing biological system offers a great opportunity.

The Opportunity

increase dairy farm productivity

If we improve the conversion of pasture protein to milk or meat by 1% from 20% to 21%, the result is an improvement of 5% in productivity


If we increase the conversion by 2% this is 10% increase in farm productivity.

If we increase the conversion by 10% this is 50% increase in farm productivity.

If we increase the conversion rate by 20% we can double current productivity.


We have the biological system, the knowledge and we offer a proven technology that can enable us to double pastoral farm productivity without having to add any more resources.

The Technology

Biozest: essential oils for improved farm efficiency

Improves  Phenylpropanoids in treated pasture.

Phenylpropanoids improve conversion of  pasture protein to milk and meat.

Phenylpropanoids therefore reduce urea excretion.

Biozest works by  eliciting  and  sustaining plants’  immune  systems. Plant immune systems are regulated by the production of a  range  of  bioactive  molecules,  the  phenylpropanoids (essential  /  aromatic  oils).


Phenylpropanoids  help  plants  to  naturally  resist  pest disease and environmental stress  or  damage.  This results in  higher  crop  or  pasture  quality  and  yield.


In  Pastoral  Farming  when livestock feed on pasture with higher content of phenylpropanoids, livestock  productivity  increases and urea  excretion  is reduced.

The Results

North Island Dairy 1 Late Season Gestating Cows

In a trial on a New Zealand dairy farm in the North Island Hauraki Plains, in late autumn; gestating dairy cows were grazed in cycles on Biozest treated pasture for a minimum of 10 days and for the rest of the grazing cycle on untreated control pasture.


Urine samples were taken and analysed for urea and creatinine content. These data are the urea, creatinine ratio.


From these data we can deduce that there was a reduction of over 20% in urea discharge when the cows grazed on Biozest treated pasture.

Reduced urea excretion in dairy cows

North Island Dairy 2 Late Season Gestating Cows

When the tests were repeated on an adjacent dairy      farm, again in late autumn on gestating cows it also resulted in reduction of over 20 % in urea discharge when the cows grazed on Biozest treated pasture.

Reduce urea excretion by New Zealand dairy cows by over 20%

South Island Dairy Peak Milk Production Season (January)

Tests on a South Island farm during the peak production season resulted in 36% reduction in urea discharge when the cows were grazing on Biozest treated pasture.


dairy cow urea discharge reduced by 36%

Dairy Goats

On a dairy goat farm. The goats are fed in cycles with a controlled quantity of freshly cut Biozest treated and Untreated pasture. They were also fed other supplementary feeds each day.


Urine tests from dairy goats that were fed treated and control pasture in cycles shows that less Urea is being discharged when the dairy goats are fed Biozest treated pasture. The urea discharge increased when they were fed control pasture.


When the goats were fed Biozest treated pasture the average reduction in urea discharge was 26%.

Dairy Goats: Milk Production

increase milk solids and milk volume by over 30%

In this whole season trial; the goats were fed Biozest treated pasture for a total of 62% of the production period. For 38% of the production period they were fed untreated pasture.


The herd size was the same over the two seasons.


The combined milk volume produced for the 2011 /2012 season increased by 31% and the total milk solid production increased by 33% compared to the previous season (2010 /2011). This data shows that the total percentage of milk solids increased more than the percentage increase in volume of milk produced. This supports the claim that Biozest increased both the volume and quality of milk.


Nitrous oxide (from Urea) has 298 times more impact per unit weight than carbon dioxide as a greenhouse gas.  Therefore the urea reduction significantly decreases farmers’ greenhouse gas liability.

This preliminary short  term test confirms that Biozest can deliver improved productivity to the sheep farming sector by increasing ewe weight and increasing lamb weight at docking.

Ewes (48), Lamb (70).

Ewes and Lambs (Weighed at Docking)

increase lamb and ewe weight

Angus Stud Conditioning Trial (68 days)

increase stud bull condition and sale price

In a trial on an Angus Stud farm the 20 bulls that grazed on treated pasture compared to the 20 control bulls gained an extra 22% in weight during the 68 day “finishing period”.


The quality “condition” of the bulls also improved.


Biozest increased bull weight and improved bull condition.


Bulls that grazed Biozest treated pasture realized higher bids at the auction. The net returns per hectare increased by over $1,600.


increase New Zealand dairy sector profits by over NZ$2 billion

An average dairy farm produces 1040Kg/ha of Milk Solids (MS)per year. (414cows).

If we took a conservative payment of $6.50 per Kg MS the revenue per hectare is $6760.


If we applied a conservative reduction in Urea – just 10%.

The theoretical improvement in production is expected to be 50%.

If we claim that only 30% increase in milk solids production is achievable.

The expected milk solids production is 1360 which will return $8840, resulting in a gross profit of $2080.

And discounting the cost of Biozest and helicopter application

This feasibility analysis indicates a net increased return of over $1000 per hectare can be achieved.

There is over 1.8 million hectares of land under dairy, therefore the total increased farm profit is approximately $2billion. Imagine, with the repercussion multiplier effect the lift to our GDP!


We have a proven technology that can enable us to double our pastoral farm productivity and abate the greenhouse gas liability. All without having to add any more resources.



Contrary to the existing paradigm, Biozest reduces the environmental impact of farming by increasing productivity.

Whether we succeed depends on the industry leaders, industry technical support organisations and CRI’s to collaborate and fast track this opportunity.
