• Moldgard inhibits the growth of 5 species of fungi.
  • Moldgard is effective at 0.5 kg/t.
  • Moldgard should be applied at more than 1kg/t for long term effectiveness.



A laboratory trial, conducted at the State Veterinary University in Warsaw, Poland to investigate the efficacy of Moldgard against various fungi.


A sample of commercial laying hen feed, with an initial moisture content of 9%, was used as the basal material for this study.

A mixed suspension of Candida albicans, Apergillus flavus, Aspergillus fumigates, Penicillium rugulosum and Fusarium graminearum at a level of 5 x 105 was mixed with 25 g of the basal feed material. Moldgard was added at rates of either 0.5, 1.0, 1.5, and 2.0 kg/t equivalent, and the samples were then incubated and mould growth analysed after 1, 2, 7, 14 and 21 days. At these time points, samples were analysed for mould growth by serial dilution and incubation at 25˚C for five days. The number of colonies counted at the start of the trial were 10,000.


  • A good level of protection was afforded by the Moldgard at all inclusion levels.
  • An inclusion of more than 1 kg/t Moldgard is required to control mould growth after 14 days of contamination.
  • This is a typical feature of mould inhibition curves as the active ingredients become depleted.
