Avivagen: Improving Global Animal & Human Health

In 2013, Cameron Groome was appointed as Chief Executive Officer and President of Avivagen, a small public company based in Ottawa. The company is now poised for change to come to Canadian animal health sciences, with their naturally-inspired feed additive OxC-beta™ Livestock (OxC-beta), and Groome hopes this technology will benefit humans too.

Groome spent years as a life science analyst and an investment banker, where he learned the knack of translating science issues to business people and vice versa. The opportunities to make a difference in animal medicine, and to have a possible impact on human health, attracted him to his current position.

OxC-beta, when added to animal feed, improves the immune system of farm and companion animals so they are better able to ward off disease. The company will soon be applying for government regulatory approval so this product will be available to Canadian feed manufacturers as a way to reduce the over-use of antibiotics.

OxC-beta has been tested against many strains of bacteria, and has no direct bacteriostatic properties; it is not an antibiotic.

“What we are doing is enhancing the ability of the immune system to recognize and respond to a bacterial challenge if and when it occurs,” Groome explained.

We don’t throw our children in a manure pile, feed them antibiotics until they are twelve years old and say, ‘Best of luck!’ And we shouldn’t be doing it for livestock either.

The genesis of the research for Avivagen’s feed supplement OxC-beta began in the early eighties. Back then, the originators were National Research Council chemists who did some seminal work on the fruit and vegetable pigments called carotenoids.

During that period, a study gave smokers supplements of a carotenoid (beta-carotene) hoping to see less cancer in the subjects, but researchers saw almost the opposite. What the chemists recognized was that when carotenoids are intact, they act as anti-oxidants, and anti-oxidants aren’t always beneficial.

Groome explained, “In our oxidation process, the carotenoid pigment compounds transform into long-chain molecules; polymers that promote better functioning of the immune system. The intact molecules act in one way, but if you let them transform through oxidation, they act in a completely different way.”

Groome shared a simple example to demonstrate this process. “You may have heard from nutritionists that the lycopene in tomatoes protects against prostate cancer and inflammation, and it seems to be better if the tomatoes have been cooked or dried—but they don’t know why.”

The team at Avivagen has explained the “why” of that; they know that when tomatoes are cooked, more of the lycopene is transformed into its oxidized form. It’s the oxidized form of carotenoids such as lycopene and beta-carotene that provide more health benefits. And so came about the development of OxC-beta (fully-oxidized beta-carotene).

“Finally, we found that one of the best uses for this is actually replacing the antibiotics that are routinely added to animal feeds,” said Groome. “Those antibiotics are ubiquitous in feeds and used widely across different livestock species, but we are creating our own monster in that we are selectively breeding—in the worst possible way—bacteria that are more resistant to antibiotics.”

Adding a mere 2 grams of OxC-beta to 1000 kilograms of feed, as opposed to hundreds of grams to kilograms of narrow or broad spectrum antibiotics, can effectively promote animal health and wellness. Livestock that have been fed the supplement show signs of improved productivity, faster growth, and more efficient feeding. But the most important benefit is that OxC-beta boosts the immune system naturally to combat infections, thereby reducing illnesses and deaths.

“We have people saying, ‘Hold on, if we can prevent disease in animals so effectively, shouldn’t we be looking at it for people who are at risk of infections?’” said Groome. “Everything we are doing at Avivagen to enhance the health of livestock is directly translatable to human health. Having high quality nutrition and an optimally functioning immune system is something we all have to care about.”

Health Canada is interested in creating a pathway to enable registration of this kind of feed supplement in Canada, and Groome hopes this will happen quickly to help Canadian livestock producers.

“There are some industry lobby groups who would have us believe that there is no link between the use of millions of kilograms of antibiotics on farms and the emergence of antibiotic-resistant bacteria, and health scientists just roll their eyes,” laughed Groome. “Not only are there hundreds of peer-reviewed publications establishing a definitive link, but it’s incredibly facile to suggest it wouldn’t happen—that these on-farm bacteria would behave in a completely different evolutionary fashion to bacteria everywhere else in nature.”

Groome described how resistant bacteria can hitch a ride off farms on boots, truck tires, water run-off, dust, meat—and breed out amongst the human population elsewhere.

“How can we do this better?” he asked. “A few years ago, people in the industry might have said that things would never change, and we will never move away from routine feeding of antibiotics.”

But change is coming. It may have begun with the World Health Organization’s concern about the increase in antibiotic-resistant pathogens, but the cry for change was taken up by restaurateurs and retailers wanting to meet the public demand for healthier food choices. And now consumers are more aware about drug-resistant bacteria and how it can affect their families.

“If you’re feeding antibiotics to animals for prophylaxis, it’s a scientific certainty you are going to create resistance in the bacterial population. You can debate the health importance of the resistance, but you can’t debate the emergence of the resistance,” said Groome.

“We should all be striving for less use of antibiotics in livestock agriculture,” stressed Groome. “We don’t throw our children in a manure pile, feed them antibiotics until they are twelve years old and say, ‘Best of luck!’ And we shouldn’t be doing it for livestock either.”

“What we see is that producers are often frantically cycling through multiple classes of antibiotics, trying to stay ahead of on-farm resistance problems,” he added. “When you’ve got genes that are increasing the minimum inhibitory concentration, it decreases bug susceptibility, and you can’t even add enough antibiotics to have the desired effects.”

While OxC-beta is protected by multiple patents, Groome insisted his company does not want to unfairly monopolize this discovery.

“We want to make this available in a way so it’s absolutely to the economic advantage of the farmer to do the right thing and use it,” he said.

The company had to go overseas to do their prove-ups by necessity, but Groome would love nothing more than to get the product on the market for Canadian producers.

So far, Avivagen’s interactions have been mostly with larger feed manufacturers in Asia, where farmers found that using the OxC-beta product showed a net positive economic benefit over what they were doing previously, including use of multiple antibiotics in their feeds.

Avivagen Inc. and UNAHCO, Inc. recently announced the registration by UNAHCO of  Livestock as an imported livestock feed additive, authorizing its use in all species in the Philippines.

“There is an incredible urgency to get antibiotics out of the food chain,” said Groome. “There have been so many issues with increasing antibiotic resistance and bleed-through of drugs and contaminants that people are saying they want to know their food was produced safely and responsibly. And the government knows that if our antibiotics stop working on common bacterial infections, the issue is not about the cost of meat, but about how we keep our people alive.”
