Comparison leafy spurge of sheep and goat preferences for
The objective of these studies was to compare preference for leafy spurge (Euphorbiu es& L.) by sheep and goats. Study 1 was a choice test that paired leafy spurge with either arrowleaf balsamroot (Balsamorhiza sagittata (Pursh)Nutt.) or crested wheatgrass (Agropyron cristatum (L.)Gaertn.) for a 30 minute feeding period. Study 2 consisted of 3 grazing trials on spurgeinfested pastures. Differen...
متن کاملSheep preference for leafy spurge from Idaho and North Dakota
Three trials were conducted to determine if low ingestion of some leafy spurge (Euphorbia esula L.) by sheep is primarily due to differences in sheep or in leafy spurge. In the first trial, pastures in Idaho and North Dakota were grazed by sheep originating from both states. Generally, sheep from both states grazed the leafy spurge growing in the Idaho pastures reluctantly but grazed the leafy ...
متن کاملTraining lambs to be weed eaters: Studies with leafy spurge
The objective of the study was to determine if exposure of young lambs to leafy spurge (Euphorbia e&u L.) would increase the consumption of this plant. Orphan lambs were exposed to leafy spurge from birth to 11 weeks of age as a water soluble extract mixed with milk replacer and as freshly harvested plants.

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Integrated Management of Leafy Spurge-Infested Rangeland
Leafy spurge is an invasive Eurasian weed on pastures and rangeland in North America where it reduces grass forage production. Our objective was to determine the effects of multispecies grazing combined with Aphthona flea beetles on leafy spurge-infested rangeland. On two westernNorth Dakota sitesdivided into four25to79-hapastures, two grazingduration treatmentswere applied: season-long with 7 ...
