Beef Cattle Grazing Preference Of Tall Fescue As Affected By Endophyte, Herbert Troye Owens Iii
Beef Cattle Grazing Preference Of Tall Fescue As Affected By Endophyte, Herbert Troye Owens Iii
University of Kentucky Master's Theses
Many factors control, contribute to, stimulate and limit forage selection. It is apparent that cattle prefer certain cultivars compared to others. This study sought to test if cattle displayed preferences for certain cultivars over a two-year period in 2008 and 2009. Determining the effect of endophyte status on preference was another objective. Previous research showed rapid increase in the selection of preferred cultivars, i.e., diet learning. We attempted to replicate those results. Forty cultivars (34 tall fescue (Lolium arundinaceum (Schreb.) Darbysh.) cultivars), two festuloliums (Festuca pratensis x Lolium perenne), two meadow fescue (Lolium pratense) and one meadow …
The Response Of Tall Fescue And Its Fungal Endophyte To Climate Change, Glade Blythe Brosi
The Response Of Tall Fescue And Its Fungal Endophyte To Climate Change, Glade Blythe Brosi
University of Kentucky Master's Theses
Tall fescue is the most common cool-season grass in the eastern USA, with broad economic and ecological importance to the region. Tall fescue is known to associate with a fungal endophyte, Neotyphodium coenophialum, whose presence can decrease biotic and abiotic stress experienced by the plant. This thesis evaluates the response of tall fescue and the fungal endophyte symbiosis to predicted climate change. I participated in two multi-factor climate change projects where I investigated the response of tall fescue tissue chemistry and growth to various climate change factors. Endophyte-infected (E+) tall fescue had decreased alkaloid production under elevated CO2 …
