Farmer's lung is a specific respiratory illness which results from the inhalation of mouldy hay, grain, straw, or other similar vegetable matter. Hay becomes mouldy if it is harvested and stored wet. Fungi and bacteria multiply in it, fermentation occurs, and heat is produced. When dry, the mouldy hay is partly converted to a fine dust. The illness was described by Campbell in 1932 and later by...

physical and chemical attributes and, moreover, possessed of a variability which, in turn, is referable to more than mere whim. As yet, the bridge is a rather shaky structure, as is recognized by the frequency with which the author is forced to indicate that insufficient data force but tentative conclusions. Nevertheless, the text clears away much rubbish and underbrush, and in some few places ...

The aim of this paper was to study of the effect of fenugreek seed (Trigonella foenum-graecum) and asparagus root (Asparagus officinalis) on in vitro digestibility and kinetics of gas production of alfalfa hay. Fenugreek seed (FS) and asparagus root (AR) were added at different levels (0, 5, 10, 15 and 20% of DM). Total phenolic components of alfalfa hay (AH), fenugreek seed (FS) and asparagus ...

By using this protocol, we successfully minimized the autofluorescence of orchard grass hay and detected rumen bacteria attached to the hay under a fluorescence microscope. R...

Changes in Se metabolism were studied in ewes fed hay containing normal or inadequate levels of Se. After intravenous injection of 75Se-sodium selenite, blood, feces and urine were collected at different times, and the concentrations of labeled and unlabeled Se were determined. Ewes were killed 1, 5, 9 or 14 d after tracer injection, and tissues were obtained for determination of radioactivity ...

The aims of this study were to estimate the risk to bakers of developing hay fever and rhinitis, to assess the modifying effect of atopy and to estimate the occurrence of job change due to nasal symptoms. A retrospective cohort study was performed among bakers trained in Swedish trade schools from 1961 to 1989 (n=2,923). School control subjects (n=1,258) comprised students in other programmes i...
