New technologies improve mycotoxin elimination: An update anno 2016
As our weapons in the fight against mycotoxins become more sophisticated, so must the methods we use to test their efficacy. Simulating intestinal conditions and "stress gene" technology are very helpful but sometimes no longer the best or fast approach to help to develop more effective elimination strategies. Recently Impextraco developed a wide range of in vivo protocols to determine the effect of mycotoxins in an early stage, using biomarkers.
Impextraco is continuously looking for the most up to date methods to evaluate and proof the efficacy of world renown mycotoxin eliminator, Elitox® . Elitox® combines three different strategies to maximize the reduction of mycotoxins.
Most mycotoxin adsorbents only bind within a certain pH-range and release the toxins as pH increases during gut propulsion. Nearly two decades ago, Impextraco introduced a gut simulation model enabling to select the most effective binders. Moreover, eliminating agents, such as enzymes and natural extracts were selected using a high throughput screening technique. The combined effect of this multiple strategy on the efficacy of eliminating mycotoxins in feed was extensively tested in vitro simulating the digestive tract. To do so Impextraco collaborated in a project to develop a gut simulator and still is intensively working on their in house gut simulation model.
The gut simulation model as a reference tool for in vitro research.
In order to determine the real binding and inactivation of mycotoxins, simple measurements in the feed are not sufficient, since the animal itself may influence the effect and pH plays an underestimated role in the absorption and desorption of certain binders. A perfect in vitro model of the animal would eliminate individual variation and control all other factors. Of course, there is no such thing as a perfect model, but the digestive tract has been well studied and several factors are easy to simulate. The following factors need to be taken into account: anaerobic environment, constant temperature, several subsequent environments at different pH, retention times and the correct subsequent addition of bile, pepsin and gut enzymes and the correct moisture to feed ratio. The advantage of this method is that by relatively simple and constant means the effects of the complete range of factors affecting in vitro results of toxin-binding can be observed.
Developing anti-mycotoxin products requires in vivo research to confirm in vitro observations. Alongside partnerships with universities, Impextraco runs its own research facilities and has validated animal models. These accurate strategies led to a unique combination of effective ingredients compiled in Elitox® , a reliable insurance policy against mycotoxins with proven efficacy in the field.
Elitox® has been already proven to be very effective in eliminating a broad range of mycotoxins, and still Impextraco's R&D department is continuously looking to improve it.
One of the most recent techniques, the one using biomarkers, has been introduced a few years ago in all our in vivo trials. Biomarkers are characteristics that are objectively measured and evaluated as indicators of biological processes, pathogenic or pharmacological responses to an intervention, such as mycotoxin ingestion. They need to be reliable, fast and easy to measure to order to find significant effects as early as possible in the animals reaction to mycotoxicosis. To find mycotoxin induced changes in the animals metabolism, Impextraco implements different strategies at the same time: blood biochemistry, flow cytometry and histopathology are just a few amongst them.
