1. Introduction

 

Air enriched with ions not only abate unpleasant odours but also protects animals from infection and ensures a better growth (Robert, 1991). Many breeders have verified the benefits of negative ionisation on animals:

  • protection against infection
  • better growth
  • better psychological health: animals are quieter

Micro-organism abatement also means less time- & money- consuming disinfection treatments.

 

Bonnevie (reported in Robert, 1991) has performed tests on mice, giving them the choice to go in 3 different cages, respectively filled with ambient, positively and negatively ionized air. The majority of animals went in the cage enriched with NAIs.

2. Poultry farm

It is well known that ammoniac acts as a growth inhibitor. Robert (1991) reports the results of a study with ionisers in a poultry farm:

 

After 5 weeks, turkeys have a 5% higher weight for a 4% lower food consumption

After 6 weeks, chicken have a 5% higher weight for a 8% lower food consumption

Within 4 weeks, rabbits have a 20% higher weight

 

Gast & Mitchell (1999) have developed an electrostatic space charge system able to produce NAIs in order to reduce airborne dust and micro-organisms in poultry areas. Abatement of 95% has been obtained on airborne and surface Salmonella enteriditis. Mitchell & al (2002) used this system in hatching cabinets, one of the primary source for Salmonella contamination, and obtained more than 93% abatement of enterobacteria and dust, generated during the hatching process.  They reproduced this experience in a breeder house (Mitchell & al, 2004)

3. Pig farm

Experiences have shown that within 2 weeks, in presence of NAIs, the pig weight is 23% higher (reported in Robert, 1991).

4. Calf farm

In presence of NAIs , the average calf weight is 19kg higher and the calf feels quieter, due to a 20% serotonin decrease in the blood (reported in Robert, 1991).

5. Horse farm

A long term study in horse quarantine boxes have shown that boxes, that were equipped with ionisers, protected their horses against contamination coming from the other boxes (Deutsche Reiterlichen Vereinigung).
