Using red kangaroos Macropus rufus Desmarest, a large (>20 kg) marsupial herbivore, we compared the digestive capabilities of juveniles with those of mature, non-lactating females on high-quality forage (chopped lucerne Medicago sativa hay) of 43+/-1% neutral-detergent fibre (NDF) and poorer quality, high-fibre forage (chopped oaten Avena sativa hay) of 64+/-1% NDF. On chopped lucerne apparent ...

Four ruminally cannulated wethers (31+/-1.3kg) were used in an experiment with a 4x4 Latin square design to estimate the DM intake, apparent digestibility, nitrogen balance, rumen ammonia and microbial protein production. The sheep had ad libitum access to either Cassia rotundifolia (Cassia), Lablab purpureus (Lablab), Macroptilium atropurpureum (Siratro) or Stylosanthes guianensis (Stylo). Dry...

I N much of the Northern Great Plains area native grasses are of paramount importance to livestock production and hays from these grasses constitute the chief roughage harvested to maintain livestock when grazing will not support them. Tonnage of prairie hay harvested in South Dakota in 1948 and 1949, a total of 4,492,000 tons, was twice as great as the harvested tonnage of all tame hays combin...

Past global change studies have identified changes in species diversity as a major mechanism regulating temporal stability of production, measured as the ratio of the mean to the standard deviation of community biomass. However, the dominant plant functional group can also strongly determine the temporal stability. Here, in a grassland ecosystem subject to 15 years of experimental warming and h...

Field dry hay needs to be reduced from near 80% moisture to 20% or less to prevent spoilage during storage. Drying hay to safe baling moistures often takes several days. Sources of loss during forage harvest include mechanical losses such as mowing, conditioning, chopping, raking, packaging and handling as well as respiration and leaching. The general relationship between forage moisture concen...

Three studies were conducted to evaluate the feeding value of slice alfalfa hay in feedlot diets. In Exp. 1, 108 steer calves (183.1 +/- 1.2 kg initial BW; 6 pens/treatment) were used in a completely randomized design to evaluate the effect of baling method on performance and morbidity of newly received calves. The study lasted 28 d. Treatments consisted of a 65% concentrate receiving diet cont...

A 5 x 5 Latin square design was used to determine the effects of restricted and ad libitum intake of diets containing wheat middlings on the site and extent of digestion compared to ad libitum intake of a corn-based diet and ad libitum intake of chopped alfalfa hay. Five ruminally and duodenally cannulated Angus steers (519 +/- 41.5 kg BW) were used to compare five dietary treatments. The five ...

Rhinitis, allergic (AR) and non-allergic (NAR), and chronic rhinosinusitis (CRS) are different expressions of upper airway inflammation. Chronic upper airway symptoms are common in childhood and adolescence. There is a need for more epidemiologic data of these different entities of upper airway symptoms in the aspects of prevalence, natural course, co-morbidity and risk factors. The aim of this...

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 ...
