Lallemand Animal Nutrition subsidiary Microbial Developments Limited appointed Jonathan Harrison as Aviguard business development manager, effective October 1.

Aviguard is an avian competitive-exclusion product that aids the rapid establishment of normal gut flora in day-old chicks, thereby minimizing colonization by transient pathogenic bacteria such as Salmonella, E. coli and Clostridium perfringens. Aviguard is sold in more than 36 countries and is used in by major producers of broilers, layers, breeders, parent and grandparent stock.

Harrison joins Microbial Developments with over 25 years in the poultry industry, including nine years with Aviagen UK/Eastern Europe, where he held various roles in business development and in global technical support for the Ross and Arbor Acre brands. Prior to this, he was an area farms manager with P.D Hook Broilers.

Harrison succeeds Sue Reynolds, who retired from Microbial Developments in August 2013 to concentrate on her farming and anaerobic digester businesses.

According to Tim Pollock, Lallemand's strategic development director: "Jonathan's in depth technical expertise across the broiler and breeder industry and his practical knowledge of hatchery and broiler farm operations will be invaluable as we continue to develop sales of Aviguard and Aviguard derivatives through our global distributor network. With ever increasing consumer and regulatory pressures on the poultry industry to minimize the routine use of antibiotics, Aviguard  is well positioned for the future, complementing our existing portfolio of poultry products, which includes Bactocell, Alkosel, Agrimos and the live probiotic yeast Levucell SB."
