Abstract

Four bales of hay were chosen from a stack of hay, barn-stored for 6 months. Each bale was subdivided into four 2·5 kg sections and one section from each bale was subjected to one of four water soaking treatments: 0, 0·5, 3 or 12 h. Post treatment, the samples were shaken for 9 min under a Negretti LS45F personal dust sampler which sampled the surrounding air. The samples were than analysed for levels of respirable particules < 5 μm in size and for amounts of sodium (Na), potassium (K), phosphorus (P), magnesium (Mg), calcium (Ca) and nitrogen (N). Soaking for 30 min reduced the number of respirable particles by about 90% but also reduced the Na, K and P content of the hay. Soaking for a longer period, at least up to 12 h, did not give a significant further reduction in number of respirable particles but there was loss of Mg and further losses in Na, K, and P. These results clearly indicate that soaking for 30 min is sufficient to reduce the respirable challenge with minimum nutrient loss.
