Fecal NIRS for predicting percent leafy spurge in diets
Research on diet selection is limited by inadequate techniques for determining botanical composition of diets. Our objective was to determine if near infrared reflectance spectroscopy (NIRS) of fecal material could be used to quantify the percentage leafy spurge (Euphorbia esula L.) in the diets of sheep (Ovis aries) and goats (Capra hircus). Fecal material representing diets of known percentag...
متن کاملIntegrated 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 ...
متن کاملPolyamines, auxins and organogenesis in leafy spurge (Euphorbia esula L.)
Canaline and canavanine (inhibitors of polyamine biosynthesis) effects on root and shoot formation were determined in vitro for etiolated hypocotyl segments of leafy spurge (Euphorbia esula L.). Canaline (an ornithine analogue) at 10 to 100 μmol/L inhibited root and shoot formation. The simultaneous application of putrescine did not reverse canaline-induced inhibition of root formation. Ornithi...

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 کاملComparison of methods for selecting fungi pathogenic to leafy spurge
Studies were conducted to compare six inoculation methods for preliminary screening of potential fungal biocontrol agents for leafy spurge (Euphorbia esula). The six inoculation methods included 1) applying spore suspensions to surface-disinfested, detached leaves of leafy spurge in petri dishes; 2) applying spore suspensions to untreated, detached leaves of leafy spurge in petri dishes; 3) app...
