Evaluation of Perennial Ryegrass Straw As a Forage Source for Ruminants
AN ABSTRACT OF THE THESIS OF Michael J. Fisher for the degree of Master of Science in Animal Sciencepresented on July 28, 2003. Title: Evaluation of Perennial Ryegrass Strawas a Forage Source for Ruminants. Redacted for Privacy Abstract approved: David W. Bohnert We conducted two experiments evaluating perennialryegrass straw as a forage source for ruminants. Experiment 1 evaluated digestion and physiological variables in steers offered perennial ryegrass straw containing increasing levels of lolitrem B. Sixteen ruminally cannulated Angus X Hereford steers (231 ± 2 kg BW)were blocked by weight and assigned randomly to one of four treatments (TRT). Steerswere provided perennial ryegrass straw at 120% of the previous 5-daverage intake. Prior to straw feeding, soybean meal (SBM) was provided (0.1% BW; CP basis) tomeet the estimated requirement for degradable intake protein. Low (L) and high(H) lolitrem B straws (<100 and 1550 ppb, respectively) were used to formulate TRT diets: LOW (100% L); LOW MIX (67% L:33% H); HIGH MIX (33% L:67% H); HIGH(100% H). Intake and digestibility of DM and OM, and ruminal pH, total VFA, andNH3-N were not affected by increasing lolitrem B concentration (P> 0.13). Ruminal indigestible ADF (IADF) fill increased linearly (P= 0.01) and JADF passage rate (%/h) decreased linearly (P = 0.04) as lolitrem B level increased. Experiment2 evaluated performance and production of 72 Angus X Herefordcows (539 ± 5 kg BW) consuming perennial ryegrass straw containing increasing levels of lolitremB during the last third of gestation. Cowswere blocked by body condition score (BCS) and randomly assigned to one of three TRT. -

Correlation of Fecal Ergovaline, Lolitrem B, and Their Metabolites in Steers Fed Endophyte Infected Perennial Ryegrass Straw
AN ABSTRACT OF THE THESIS OF Lia D. Murty for the degree of Master of Science in Pharmacy presented on November 21, 2012. Title: Correlation of Fecal Ergovaline, Lolitrem B, and their Metabolites in Steers Fed Endophyte Infected Perennial Ryegrass Straw Abstract approved: A. Morrie Craig Perennial ryegrass (PRG, Lolium perenne) is a hardy cool-season grass that is infected with the endophytic fungus Neotyphodium lolii, which enables the plant to be insect repellant and drought resistant, lowering the use of insecticides and fertilizers. However, this fungus produces the compound lolitrem B (LB, m/z 686.4) which causes the tremorgenic neurotoxicity syndrome ‘ryegrass staggers’ in livestock consuming forage which contains <2000 ppb LB. Ergovaline (EV, m/z 534) is a vasoconstrictor normally associated with tall fescue (Festuca arudinacea), but has also been found in endophyte- infected PRG. Past research has shown a strong linear correlation between levels of LB and EV in PRG. The purpose of this study was to examine the linear relationship between EV and LB in feces and determine common metabolites. To accomplish this, four groups of steers (n=6/group) consumed endophyte- infected PRG over 70 days consumed the following averages of LB and EV: group I 2254ppb LB/633 ppb EV; group II 1554ppb LB/ 373ppb EV, group III 1011ppb LB/259ppb EV, and group IV 246ppb LB/<100ppb EV. Group I in week 4 was inadvertently given a washout period at which time the steers consumed the amount of LB and EV given to group IV (control). Both feed and feces samples were extracted using difference solid phase extraction methods and quantified by HPLC-fluorescence for LB and EV. -

Hazlett Rocky Mountain Research Station General Technical Report RMRS-GTR-130 June 2004 Hazlett, Donald L. 2004. Vascular plant species of the Comanche National Grassland in southeast- ern Colorado. Gen. Tech. Rep. RMRS-GTR-130. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 36 p. Abstract This checklist has 785 species and 801 taxa (for taxa, the varieties and subspecies are included in the count) in 90 plant families. The most common plant families are the grasses (Poaceae) and the sunflower family (Asteraceae). Of this total, 513 taxa are definitely known to occur on the Comanche National Grassland. The remaining 288 taxa occur in nearby areas of southeastern Colorado and may be discovered on the Comanche National Grassland. The Author Dr. Donald L. Hazlett has worked as an ecologist, botanist, ethnobotanist, and teacher in Latin America and in Colorado. He has specialized in the flora of the eastern plains since 1985. His many years in Latin America prompted him to include Spanish common names in this report, names that are seldom reported in floristic pub- lications. He is also compiling plant folklore stories for Great Plains plants. Since Don is a native of Otero county, this project was of special interest.

Hazlett, a native of the eastern plains of Colorado, has lived and worked in the Pawnee National Grassland region since 1983. Before 1983 Don spent 12 years working in Honduras and Costa Rica. He has worked for Colorado State University as site manager for the Central Plains Experimental Range, as a visiting professor in the biology department, and as a plant taxonomist for the Center for Ecological Management of Military Lands. Since 1995 Don has been a research contractor for ecological and floristic studies in the western United States. He prefers ethnobotanical studies.

Necropsy Findings in Ruminant Poisonings by Plant, Fungal, Cyanobacterial and Animal-Origin Toxins in Australia R a Mckenzie
Chapter 17 Necropsy Findings in Ruminant Poisonings by Plant, Fungal, Cyanobacterial and Animal-Origin Toxins in Australia R A McKenzie INTRODUCTION Poisoning of ruminants affects virtually all body systems. These notes will deal with lesions detectable at necropsy of ruminants poisoned by natural toxins from (1) a clinical perspective and system by system and (2) a toxin perspective. Major toxin sources, pathology and a ppraoches to diagnosis are listed Suggestions for confirmation of diagnoses are also included. All data in this work are drawn from McKenzie RA (2002) Toxicology for Australlbn Veterinarians. (published by the author : 26 Cypress Drive, Ashgrove 4060; phone 07 3366 5038; e-mail [email protected]) which should be consulted for more information on the syndromes and toxins included and references to the data. CLINICAL CONSPECTUS This section gives an overview of natural toxins and toxin sources affecting ruminants arranged by syndrome or affected organ system to help with differential diagnosis of cases. Sudden death syndromes 'Sudden' death is defined as death occurring so rapidly that affected animals are found dead without being seen to be ill or die within a few minutes to a few hours of clinical signs being noticed. Of course, the transition from life to death itself is always sudden, that is, instantaneous.
