Recovery of Yearling Calves from Fescue Toxicosis [PDF]
, 2023 Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) is widely utilized for grazing in the transition zone between the temperate and subtropical regions of the eastern U.S.A. Cattle grazing tall fescue frequently exhibit fescue toxicosis, a malady

Functional Ecology, Volume 37, Issue 6, Page 1567-1579, June 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract Many temperate grasses are both hyper‐accumulators of silicon (Si) and hosts of Epichloë fungal endophytes, functional traits which may alleviate environmental stresses such as herbivore attack.

Crop Science, Volume 62, Issue 3, Page 1394-1403, May/June 2022., 2022 Abstract Frost seeding is a low‐cost effective strategy to introduce legumes into existing perennial pastures; however, it has been deemed unreliable in the upper southeast USA. We evaluated frost seeding planting rate effects of clover (Trifolium spp.) during the year of establishment on productivity and nutritive value of clover‐tall fescue [Festuca ...

Ergot alkaloids in New Zealand pastures and their impact
New Zealand Journal of Agricultural Research, Volume 65, Issue 1, Page 1-41, February 2022., 2022 ABSTRACT In identifying endophytes for use in pastures in New Zealand there have been two strategies used, either exclusion of ergopeptine and lolitrem alkaloids or, retaining some ergopeptine expression to enhance the stability of natural defences against invertebrate pests. Both have their strengths and weaknesses.

Pituitary genomic expression profiles of steers are altered by grazing of high vs. low endophyte-infected tall fescue forages. [PDF]
PLoS ONE, 2017 Consumption of ergot alkaloid-containing tall fescue grass impairs several metabolic, vascular, growth, and reproductive processes in cattle, collectively producing a clinical condition known as "fescue toxicosis." Despite the apparent association ...

Non-Invasive Techniques Reveal Heifer Response to Fescue Endophyte Type in Grazing Studies
Animals, 2023 Cattle grazing tall fescue (Schedonorus arundinaceous) infected with wild-type endophytes (WE) leads to a syndrome commonly known as fescue toxicosis. Replacing WE tall fescue with a novel endophyte-infected (NE) tall fescue can mitigate this problem but
