Spotted Knapweed Utilization by Sequential Cattle and Sheep Grazing

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...

Impact of grazing management on cattle and sheep parasites

A Review: Comparison between Grazing Behavior of Cattle and Sheep

The aim of this study was to investigate the behavior of cattle and sheep grazing and expression of behavioral differences between cattle and sheep is because, to thereby allow grazing management strategies amid animal feed. Grazing circumstances, the daily consumption and duration is grazing, it can result from consumption of feed bite mass (mass and carved teeth) and tooth cutting (bite rate)...

Grazing of spotted locoweed (Astragalus lentiginosus) by cattle and horses in Arizona.

Spotted locoweed (Astragalus lentiginosus var. diphysus) is a toxic, perennial plant that may, if sufficient precipitation occurs, dominate the herbaceous vegetation of pinyon-juniper woodlands on the Colorado Plateau. Six cow/calf pairs and four horses grazed a 20-ha pasture with dense patches of locoweed in eastern Arizona during spring 1998. Locoweed density was 0.7 plants/m2 in the pasture....

Fungal endophytes in spotted knapweed influence its competitive interactions

Fungal endophytes in spotted knapweed influence its competitive interactions. Abstract Fungal symbionts are often overlooked in studies of plant invasion. Nevertheless, their role could be essential to the competitive success of the invader. We studied fungal endophytes in the widespread invasive Centaurea stoebe (common knapweed). A preliminary experiment showed that endophytes in roots of C. ...
