When was ECO formed and why?

ECO began as a “virtual“ company around 1995 within Lawrence plc. ECO identified a number of best-selling animal health medicines, sourced them and commenced licensing of them. The strategy was to add a range of therapeutic, vet prescribed medicines for the treatment of food producing animals to complement Lawrence plc’s range of natural feed additives, which it sold internationally. In 2007, Lawrence changed its name to ECO Animal Health as the business had become entirely focused on animal health.

What is Aivlosin® / Valosin®?

Aivlosin® / Valosin® is a highly effective antibiotic that treats a range of specific enteric (gut) and respiratory diseases in pigs and poultry thereby ensuring a rapid return to health and optimum production. It must be prescribed by a veterinarian and is always used at low dose rates and for short treatment durations.

Why did the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) license a novel medicine like Aivlosin®?

Aivlosin®/Valosin® has passed all the stringent tests required by these regulatory authorities. These tests include proving safety (to animals, to humans and to the environment), product quality and clinical efficacy against specific diseases in the target species while ensuring zero antibiotic residues in the meat or eggs that are eaten.

Aivlosin®/Valosin® has the profile of a modern antibiotic in that it is used to treat specific named diseases, its effective dose rate is low and the duration of treatment is short and it must be administered under veterinary supervision. Aivlosin®/Valosin® is not used in human medicine. Aivlosin’s® profile is very much in line with current thinking regarding the judicious use of antimicrobials in farm animals and the desire to reduce the amounts of antibiotics used in farming.

Why should Aivlosin® / Valosin® be the medicine of choice for farmers?

That is simple! Aivlosin® / Valosin® is highly effective and works quickly, allowing treated animals to return to health faster. In addition to the obvious welfare benefits, animals gain weight faster, digest food more efficiently and get to market earlier which all adds up to more money for the grower.

What else does ECO sell?

We have a range of modern generic medicines, which also require active ongoing licensing support. The range is led by ECOMECTIN®, an endectocide that controls worms, ticks, lice and mange in grazing stock and pigs.
