Exposure to ergot alkaloids during gestation reduces fetal growth in sheep
Tall fescue [Lolium arundinaceum (Schreb.) Darbysh; Schedonorus phoenix (Scop.) Holub] is the primary cool season perennial grass in the eastern U.S. Most tall fescue contains an endophyte (Neotyphodium coenophialum), which produces ergot alkaloids that cause vasoconstriction and could restrict blood flow to the fetus in pregnant animals. The objective of this study was to examine fetal growth ...
متن کاملPhysiological and digestive effects of Neotyphodium coenophialum-infected tall fescue fed to lambs.
The digestive responses and degradation of ergovaline and production of lysergic acid in the rumen of sheep offered Neotyphodium coenophialum-infected tall fescue straw at 2 ergovaline levels were investigated. Six crossbred wethers (56 +/- 3.0 kg of BW) were used in a randomized crossover design involving 2 treatments, for a total of 6 observations per treatment. The experiment consisted of tw...
متن کاملTall Fescue Toxicosis in Meat Goats
Tall fescue (Schedonorus phoenix (Scop.) Holub) is a cool-season bunchgrass that grows throughout the eastern half of the United States and in the Pacific northwestern region of the country. It is estimated that over 90% of tall fescue pastures are infected with the fungal endophyte Neotyphodium coenophialum (Bacon and Siegel, 1988; Glenn et al., 1996). Tall fescue is native to Europe and was f...
متن کاملNovel Endophyte-Infected Tall Fescue
Tall fescue (Schedonorus phoenix (Scop.) Holub) is a cool season perennial grass that fills a critical forage produc-tion gap in the Southeast and is the predominant forage crop in much of the U.S. In fact, this species is the most widely used grass in improved U.S. pastures, occupying more than 36 million acres. Its popularity is related to establishment ease, drought tolerance, excellent graz...
متن کاملInfluence of dietary endophyte (Neotyphodium coenophialum)-infected tall fescue (Festuca arundinacea) seed on fecal shedding of antibiotic resistance-selected Escherichia coli O157:H7 in ewes.
The objectives were to determine the effects of short-term feeding of a toxic endophyte (Neotyphodium coenophialum)-infected tall fescue seed (Festuca arundinacea, cultivar 'Kentucky 31') on fecal shedding and intestinal concentrations of Escherichia coli O157:H7 and the concentrations of prolactin, cortisol, and NEFA in experimentally inoculated ewes. Twelve ewes (mean BW = 46 +/- 2 kg) were f...
