Microbial Developments Limited, a subsidiary of Lallemand Animal Nutrition, has appointed Jonathan Harrison as business development manager for Aviguard, effective from October 2013.

Aviguard is the organisation's avian competitive exclusion product which aids the rapid establishment of normal gut flora in day old chicks, thus minimising colonisation by transient pathogenic bacteria such as Salmonella, E. Coli and Clostridium perfringens.

Harrison has over 25 years of experience in the poultry industry. He was previously with Aviagen UK/Eastern Europe where he held various roles in business development and global technical support for the Ross and Arbor Acre brands, covering all aspects of breeding and broiler production. Prior to this, he was an area farms manager with P.D Hook Broilers.
