Delacon researchers developed a new class of phytogenic feed additives in the 1980s, establishing the de facto industry standard.

Thus the actual mechanism by which sub-therapeutic antibiotic feed additives serve as growth promotors is unclear.

Nearly half the 50 million pounds of antibiotics produced in the United States are used in animals, mostly as feed additives to promote growth.

Different feed additives may function as stimulator or modulator of immunity processes.

Some feed additives have the potential to reduce the amount of ammonia found in the manure of the animals or in the barn air.

Nonetheless it has a relatively simple objective: to harmonise procedures governing the authorisation of feed additives.

This proposal represents a major streamlining of the current rules on safety evaluation and marketing authorisations for feed additives.

Today, we are embarking on a new round which focusses on feed additives.

I believe that it is important to renew the directive on feed additives, starting with the aims that are set out in the resolution.

Seventy percent of all antibiotics and related drugs are given to animals as feed additives.
