Download or read book Managing Fescue Toxicosis Through Forage Canopy Limestone Application and Novel Endophytes written by Sarah Lynn Kenyon and published by . This book was released on 2017 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tall fescue [Lolium arundinaceum (Schreb.) Darbysh.] infected with the endophytic fungus Epichloë coenophiala [(Morgan-Jones [AND] W. Gams) C.W. Bacon & Schardl, comb. nov.] produces ergovaline and other alkaloids responsible for fescue toxicosis, a livestock disorder. Cultivars re-infected with endophytes that do not produce toxic ergot alkaloids, referred to as "novel endophytes," have been used to alleviate the symptoms of fescue toxicosis. This research includes a series of experiments with the overall objective of identifying management practices that reduce fescue toxicosis in order to provide recommendations to Missouri farmers. The fist experiment examined the distribution of ergovaline and total ergot alkaloids throughout the vegetative canopy of tall fescue, and concluded that toxin concentrations are highest in the bottom 5 cm of the plant. The second experiment documented that applying limestone decreased ergovaline concentrations by at least 20 [mu]g kg−1 dry matter. The third experiment evaluated cattle preference among novel endophyte-infected tall fescue cultivars. This experiment concluded that one cultivar, 'BarOptima,' was grazed first and most frequently.

This book was released on 2019-08-22 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management Strategies for Sustainable Cattle Production in Southern Pastures is a practical resource for scientists, students, and stakeholders who want to understand the relationships between soil-plant interactions and pasture management strategies, and the resultant performance of cow-calf and stocker cattle. This book illustrates the importance of matching cattle breed types and plant hardiness zones to optimize cattle production from forages and pastures. It explains the biologic and economic implications of grazing management decisions made to improve sustainability of pastures and cattle production while being compliant with present and future environmental concerns and cattle welfare programs. Documents the effects of cattle grazing on greenhouse gas emissions and carbon footprints Discusses strategies to enhance soil fertility, soil health, and nutrient cycling in pastures Provides information on the use of stocking rates, stocking strategies and grazing systems to optimize cow-calf production of weaned calves and stockers. Presents innovations in cattle supplementation and watering systems to minimize negative impacts on water and soil health Includes methods for weed control to maintain pasture condition and ecosystem stability Describes management strategies to integrate cattle operations with wildlife sustainability
Download or read book Tall Fescue Toxicosis written by Craig Arthur Roberts and published by . This book was released on 2000 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tall fescue (Festuca arundinacea) is Missouri's most widely used forage crop. It is insect and nematode resistant, tolerates poor soil and climatic conditions well and has a long growing season. Unfortunately, tall fescue also has a downside. Most tall fescue in the state is infected with a fungal endophyte, Neotyphodium coenophialum (formerly called Acremonium coenophialum) that is toxic to animals. This publication offers a description of the endophyte as well as recommendations for its management.

Available in PDF, EPUB and Kindle. Book excerpt: An 84 d randomized block design using beef calves (238.8 " 20.1 kg) in each of two years was used to assess the efficacy of energy supplementation and glucomannan (MTB) to alleviate tall fescue toxicosis. Groups of four calves were randomly assigned to 24 endophyte-infected tall fescue pastures (1.23 " 0.06) ha. Pastures of calves were randomly assigned to treatments: unsupplemented (CON) with soybean hulls (SH) at 0.33% BW (DM basis; LO) supplemented with SH at 0.66% BW (DM basis; HI), LO plus 20 ·ghd−1 MTB-100® (LO-MTB), HI plus g·hd−1·d−1 MTB-100® (HI-MTB). Calves were weighed and serum collected every 21 days. Fecal grab samples were taken from d 55 to d 59 and analyzed for dry matter chromium and ergot alkaloid concentrations. Tympanic temperatures were taken from one calf for 3 days each week from d 59 to d 84. Data were analyzed using the MIXED procedure in SAS with contrasts of effects of MTB, level of SH supplementation (LEVEL), MTB x LEVEL interaction, and CON vs. supplemented (SUPP). Treatments differed in ADG (P

Download or read book Ameliorating the Effects of Fescue Toxicosis in Heifers with Blessed Thistle written by Abby Razer and published by . This book was released on 2011 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fescue Toxicosis occurs when animals are fed or grazing on Tall Fescue (Festuca arundinacea ) syn. (Lolium arudinacea [Schreb]) grass that is infected with the endophytic fungus Neotyphodium coenophialum (Bacon et al., 1977). This disease affects cattle, sheep, and horses causing reduced feed consumption, average daily gain (ADG), and reproductive performance (Hoveland, 2003). The aim of this research project was to determine if the herbal supplement, Blessed Thistle, could be used to counteract the effects of fescue toxicosis in cattle. The results suggest that Blessed Thistle can ameliorate some symptoms of fescue toxicosis; however, further research is needed.

Download or read book Feed Intake Component of Fescue Toxicosis During Short term Exposure to Thermoneutral and Heat Stress Conditions written by Prakash Babu Bommala and published by . This book was released on 2008 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ingestion of endophyte-infected tall fescue (E+) may result in fescue toxicosis, which is associated with a significant reduction in feed intake. It is possible that the reduction in caloric intake could contribute to some of the symptoms associated with this condition. The following study evaluated this possibility. Time-related changes in core body temperature (Tc), activity, feed intake and body weight were determined in rats fed diets containing either endophyte-infected seed (E+), uninfected fescue seed (E- ), or uninfected fescue seed at the level consumed on the previous day by rats fed the E+ diet (PFE+; pair-fed). These diets were fed for seven days at thermoneutrality (i.e., 21°C), followed by three days of exposure to thermoneutral (TN; 21°C) or heat stress environments (HS; 31°C). Cumulative effects of both E+ diet and HS on feed intake and body weight gain were observed. Average daily Tc of E+ and PFE+ rats tended to decrease during the preheat period by reducing the daily minimum Tc, with greater reduction in the PFE+ group. During HS, the average daily Tc of E+ group increased with a shift in diurnal Tc values to a higher level indicative of hyperthermia. In contrast, the daily Tc and circadian rhythm of the PFE+ group was similar to TN groups, suggesting that reduced feed intake might explain the hypothermia experienced during at thermoneutrality, but not the hyperthermia experienced by the E+ group during heat stress. Prolactin levels were decreased in E+ fed rats irrespective of ambient temperature. There was no effect of E+ treatment on serum parameters at TN. During HS, E+ treatment lowered cholesterol and amylase levels relative to E- levels. The PFE+ treatment lowered cholesterol in both environments, and reduced amylase, ALP, and albumin relative to E- treated animals in the HS environment. The above results suggest that decreased feed intake partially contributes to the hypothermia at thermoneutrality in E+ and PFE+ groups, but only explains some of the E+ effects during short-term heat stress.
