Development of New Measurements and Tools to Mitigate Fescue Toxicosis in Beef Cattle [PDF]
The objective of this study was to identify new ways to determine the severity of fescue toxicosis and identify genetic differences in fescue impacted traits as a basis in understanding how cattle could be selected for tolerance to fescue toxicosis.

Asexual Epichloë Fungi—Obligate Mutualists
Asexual Epichloë are obligate fungal mutualists that form symbiosis with many temperate grass species, providing several advantages to the host. These advantages include protection against vertebrate and invertebrate herbivores (i.e., grazing livestock ...

Variability of Ergovaline and Total Ergot Alkaloid Expression among Endophytic Tall Fescue Cultivars
ABSTRACT Tall fescue (Lolium arundinaceum [Schreb.] Darbysh.) is one of the most widely grown grasses in the United States. Most plants are infected with an endophyte, Epichloë coenophiala Bacon and Schardl. This endophyte produces high concentrations of ergot alkaloids, which cause fescue toxicosis in livestock. The economic losses to the US livestock

Two tall fescue [Lolium arundinaceum (Schreb.) Darbysh. = Schedonorus arundinaceus (Schreb.) Dumort. = Festuca arundinacea var. arundinacea Schreb.] plant genotypes with an Epichloë coenophiala (Morgan‐Jones & W. Gams) C.W. Bacon & Schardl common toxic endophyte (CTE), one with a nontoxic strain (NTE19) and one with another Epichloë species (FaTG‐4 ...

Abstract Red clover (Trifolium pratense L.) is a widely grown perennial forage legume that supports sustainable livestock production through its high nutritive value and bioactive isoflavones. Future climate change, particularly warming and increased rainfall, may influence forage accumulation and isoflavone concentrations.

Cross‐sectional survey and retrospective data on the oestrus synchronization were collected and analysed. The predominant mating system practiced by dairy farmers was AI (55.6%), and 73.5% of farmers apply controlled mating. The highest response rate and pregnancy rate were 89.5% and 45.2%, respectively, whereas a birth rate of 9.6%–18.5% was obtained.

We outline the diversity of pests, weeds and plant pathogens absent from New Zealand that threaten forage production, examine their potential import pathways, and outline the challenges of managing them should they arrive. The number and diversity of threats and pathways indicates ongoing incursions are inevitable.

A comparison of four methods for determining pasture botanical composition
The objective of this study was to determine an accurate and efficient method for researchers and/or practitioners to monitor botanical composition. The evaluation methods included visual estimation (top left), occupancy grid (top right), point quadrat (bottom left), and step point (bottom right).
