Finding natural solutions for food production without antibiotics. Together with a group of French farmers and a feed mill, animal nutrition company Olmix is working towards this goal. The results are promising.

"Excessive and inappropriate use of antimicrobial drugs is accelerating the appearance of antibiotic-resistant bacteria. As such, common infections and minor injuries that have been treatable for decades may once again kill", World Health Organisation's coordinator for antimicrobial resistance Charles Penn addressed earlier. Former chief economist at Goldman Sachs Jim O'Neil even said once that by 2050, the number of deaths due to infections by antibiotic resistant bacteria would reach 50 million/year globally, more than cancer or any other disease with 10 million deaths in China alone.

Algae in feed

Producers face many problems trying to establish a healthy food chain and reducing antibiotics for food producing animals is a key topic. Nutritional strategies are an essential part to reduce antibiotics. Founder of Olmix, Herve Balusson, names algae as a renewable raw material with unexpected potential, and thus a promising ingredient for livestock feed. Algae has been proven to enhance the immune system of animals, increase gut health, increased digestive efficiency and protection against mycotoxins. To prove that these strategies work, Olmix is collaborating with a feed manufacturer and a group of farmers in France to produce antibiotic-free chicken.

In doing so, the conventional production scheme was maintained (intermediate growth strain, 40-day slaughtering and rearing in poultry houses), while the farming hygiene and feed programmes were adapted to include several Olmix products in the feed and drinking water. "The results are successful: from an industry that used antibiotics on more than 50 percent of batches, we managed to reduce antibiotics (including medicinal antibiotics) completely on more than 95 percent of batches. The results were also noteworthy in terms of zootechnical performance, since there was no deterioration and even an improvement in certain indicators such as the age at which the chickens were removed for slaughtering," said Dr Thomas Pavie, Director 'One Health' at Olmix.
