Importance Of Grass-Legume Choices On Cattle Grazing Behavior And Performance, Brody Todd Maughan May 2013

Importance Of Grass-Legume Choices On Cattle Grazing Behavior And Performance, Brody Todd Maughan

All Graduate Theses and Dissertations

Pastures have been typically dominated by monocultures, only allowing herbivores access to one food type with unbalanced nutrient content and in some instances with single plant secondary compounds (SCs), which can be toxic if ingested at high concentrations. By establishing diverse pastures animals can select from a variety of plants with different concentrations and types of nutrients and SCs. The objectives of my study were to (a) determine if the type of plant diversity - tall fescue with either tannin-containing sainfoin or saponin-containing alfalfa − affects cattle preferences for these forages, (b) evaluate how readily fall-born calves reach finish body condition on ...


Forage Yield And Quality Of Binary Grass-Legume Mixtures Of Tall Fescue, Orchardgrass, Meadow Brome, Alfalfa, Birdsfoot Trefoil, And Cicer Milkvetch, Steven R. Cox May 2013

Rising fertilizer prices have led a return to the use of grass-legume mixtures to reduce N costs and improve pasture productivity. The objective of this study was to determine optimal species combinations of binary grass-legume mixtures to improve forage production and pasture nutritive value in irrigated pastures of the Intermountain West. The study was conducted at the Utah State University Intermountain Pature Research Facility near Lewiston, UT. Tall Fescue (TF), Orchardgrass (OG), and meadow brome (MB) were grown with alfalfa (ALF), birdsfoot trefoil (BFTF), and cicer milkvetch (CMV) in legume-grass mixes and monocultures at planting ratios of 25:75, 50 ...
