Prof. Veerle Fievez

PROFESSOR OF ANIMAL NUTRITION, GHENT UNIVERSITY

Veerle Fievez obtained her PhD in Applied Biological Sciences, Ghent University in 2002 and is currently Professor of Animal Nutrition at Ghent University’s Department of Animal Production.

Although her main expertise is on ruminant nutrition and microbial digestion and its importance in livestock production, her MSc degree was not in Animal Science. Veerle graduated in bioscientific engineering with a focus on environmental technology.

This background results in a specific approach for her research group, where new developments are explored from an engineer’s perspective for potential applications. Furthermore, environmental challenges within livestock production have always been a major focus of the group.

At Mootral, we believe that bringing together scientific leaders from all over the world enables and facilitates research for a healthy planet.

PAST RESEARCH

Our researchers have proven in-vitro, ex-vivo and in-vivo efficacy in manipulating rumen fermentation and reducing methanogenesis by 20-99%.

Mootral_barn

Research has included the development of patented extraction processes and is addressing the stability of garlic’s natural compounds, which has allowed the raw materials to be commercialised in a number of agricultural applications. Early efficacy trials included the rumen simulating technique (RUSITEC) with sheep and cattle rumen fluid with Prof. Jamie Newbold, the leading Professor of agricultural research at IBERS, UK, showed methane reduction of 35% and 94% respectively.
 
In-vivo trials with cattle and sheep in the UK as performed by IBERS and DEFRA showed that initial iterations of the concept could reduce methane emissions from cattle and other ruminants by 20-27%.

Our technology was part of the large EU funded collaborative research project SMEthane, (which included collaboration with Professor Newbold, Dr David Yanez-Ruiz of CSIC, Professor Veerle Fievez of Ghent University and DEFRA) where methane reduction was shown at up to 94%. This work was published in EU Research Agency and UK Government Agency reports as well as peer reviewed journals.[5][6][7][8]

Since the completion of the Pan-European collaborative research project, our research arm, Neem Biotech, has invested 2 years into further validating stability and efficacy of the product, which is now scalable, affordable and palatable to cows. A key consideration was to ensure ease of market entry as a feed supplement, fit for the feed chain[9].


FURTHER RESEARCH

We constantly undertake extensive further research in order to validate the superior competitive efficacy versus all available and planned compounds, to gain further insights into even more cost effective administration approaches over the lifetime of the animal, to obtain more in-depth understanding of the specific mode of action using pioneering DNA and genomics approaches and to validate the efficacy and practicality under differing local conditions (i.e. Scandinavia, U.S. and LATAM).

Cows Grazing

The validation work included in vitro batch incubations with rumen fluid from animals on varying diets in collaboration with Prof. Veerle Fievez and further iterations of the Rusitec equipment with Prof. Gerhard Breves and Prof. Jamie Newbold.

Batch culture data shows methane reductions of 82% with an increase in volatile fatty acids indicating positive effects on the healthy growth and wellbeing of the animal as a result of supplementation. Independent verification of the batch culture data using the Hohenheim Gas Test shows reductions of methane production of over 65% using various formulations of Mootral indicating the consistency of the approach. Volatile fatty acid increases are congruent with those found earlier in batch culture again indicating positive effects on the healthy growth and wellbeing of the animal as a result of supplementation.

Rusitec data from Hannover and IBERS show reproducibility in reduction of methane production results using rumen fluid from different species of cattle on varying diets. Methane production could be reduced significantly by up to 90%.

In 2017, Mootral was subject to a palatability trial in beef cattle in Italy and Belgium. It was concluded that Mootral was very well accepted by the animals and no impact on feed intake was noted. Furthermore, Mootral was tested in a six-week feeding trial on a commercial dairy farm in the Netherlands under normal operational conditions.

Mootral had positive effects on the milk yield and the composition of the milk. It was also noted that the somatic cell count in milk as an indicator of udder health decreased in the Mootral group. Results from this trial were presented on a poster at the IDF World Dairy Summit in Belfast.


BREAKING NEW SCIENTIFIC GROUND

As our data strongly suggests that the effect of our solution, in contrast to other historically studied alternatives, is not transient, we have decided to validate the on-going changes in the gut microbiome at a genomic level.

Mootral_507335385

This is specifically to show that the changes in the rumen microbiome that are evidenced are not transient but show a stable transition in the bacterial population from one geared to methane production to one promoting growth. This is in comparison to work done previously, which only considers the before/after genomics but does not consider stability of any changes affected by the dietary intervention.

The aim is to use the data to refine our intervention, and intervention strategy to further improve the reduction in methanogenesis whilst promoting the production of the specific short chain fatty acids that promote animal growth.

We are currently working with three research institutes in Hannover (Germany), Ghent (Belgium) and Aberystwyth (Wales) in independent trials to validate this approach.
