Comparisons of Cattle Grazing and Sheep Grazing

Controversy has surrounded the possible differences in pasture production which result from grazing by cattle or sheep. Experiments conducted over the 1972-76 period show that pasture production under grazing by sheep is greater than under grazing by cattle under similar intensive managements. A change from sheep grazing to cattle grazing can cause a rapid deterioration in pasture production, w...

Long-term grazing effects on genetic variation in Idaho fescue

The effect of cattle grazing on the genetic structure of native grass populations has received little attention. We investigated the effect of cattle grazing on genetic variation in Idaho fescue (Festuca idahoensis Elmer) using ISSR (inter-simple sequence repeat) DNA markers. The ISSR markers are hypervariable and are generally interpreted as being selectively neutral. Idaho fescue tillers were...

Climate Corrections to the Seasonal Wool Growth Rhythm of Sheep Grazing in a Southern Australian Environment

Substantial rhythms in clean wool, wax and suint production have been observed for dry, spring-shorn Merino ewes maintained od a uniform plane of nutrition in exposed pens. Changes can be related directly to mean daily temperatures. Reversed rhythms were recorded for dry, spring-shorn, grazing sheep where both nutrition and climate were changing. Thus climate corrections would enhance the nutri...
