1983
Marjut Kotimaa | Mirja Mustonen | Kaj Husman
The quality and the quantity of spore dust liberated from bales of hay treated with different doses of ammonium propionate (ADD-H) were studied during one indoor foddering period. The quantity of both mesophilic mold spores (especially Aspergillus umbrosus) and of thermophilic actinomycetes liberated from bales not treated with ADD-H was statistically significantly greater than the amount liberated from treated bales. There were no statistically significant differences in the amount of spores liberated from the bales treated with different doses of ADD-H.
