the aetiology behind odor-related chronic somatic symptoms (o-rcss) is unknown, although both immunological and psychiatric causes have been suggested. the aim of this study was to investigate the occurrence of self-reported asthma and hay fever and psychiatric symptoms in individuals having o-rcss compared to individuals with similar chronic somatic symptoms (css) which were not odors-related,...

Cropping systems in Western Australia (WA) are strongly dominated by cereals (wheat, barley and oaten hay) and are inextricably linked to soil quality and moisture supply. So a major research challenge is to devise cropping systems that improve soil health and maximise water-use efficiency. For a profitable and sustainable production system there is a clear need for ‘break crop’ to provide a pe...

This experiment was carried out to study the effect of a directly fed exogenous fibrolytic enzyme on intake and digestion of DM, OM, protein, NDF, ADF, and hemicellulose of alfalfa and ryegrass hay by sheep. Four diets were randomly assigned to four ruminally cannulated lambs using a 4 x 4 Latin square design, repeated in time, with a factorial arrangement (2 x 2) of diets: 1) alfalfa hay; 2) a...

To visualize and localize specific bacteria associated with plant materials, a new fluorescence in situ hybridization (FISH) protocol was established. 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. Real-time PCR assays were also employed to quantitatively monitor the rep...

Alfalfa was harvested from alternate windrows as 40% DM silage or hay in small rectangular bales and fed in two 12-wk 4 x 4 Latin square trials, each with 20 multiparous lactating cows (4 with ruminal cannulas). Diets contained (DM basis) 69 (trial 1) or 66% (trial 2) alfalfa, 26 to 33% high moisture corn, 1.3% minerals and vitamins, and about 1.6 Mcal of NEL/kg of DM. In trial 1, second-cuttin...

The response of montane and subalpine hay meadow plant and arthropod communities to the application of liquid manure and aerial irrigation - two novel, rapidly spreading management practices - remains poorly understood, which hampers the formulation of best practice management recommendations for both hay production and biodiversity preservation. In these nutrient-poor mountain grasslands, a mo...

I . In four feeding experiments with sheep the utilization of proteins contained in lucerne hay and of those in toasted soya-bean meal (SBM), representing a roughage and concentrate feed respectively, were examined. The ration of one group of animals contained lucerne hay as sole source of digestible protein and that of the other SBM. 2. Measurements of the nitrogen balance showed clearly the s...
