A Pilot Study Of Sheep Disease Surveillance In Western Australia, Roy Butler

Conference papers and presentations

A pilot study of sheep disease surveillance was conducted in 2014-2015 on four farms in the eastern wheatbelt of Western Australia. The participants observed their sheep, sufficiently closely to notice disease, at least every second day. Most of the disease syndrome reports related to fewer than five sheep, demonstrating that farmers noticed problems in individual sheep, and not only in groups of sheep. Of a total of 66 disease syndrome observations reported over 12 months, the three most frequently occurring syndromes were found dead + sudden death (combined), skin lesions, and lameness.

Impact Of Stress Hormones And Iugr Fetal Conditions On Myoblast Function, Hannah E. Riley, Kristin A. Beede, Dustin T. Yates

UCARE Research Products

Chronic fetal stress causes adaptive responses that result in intrauterine growth restriction (IUGR). Maternal stressors including heat stress, illness, and obesity cause placental dysfunction that harshens the intrauterine environment by inducing hypoxia and nutrient restriction. IUGR fetuses have restricted growth through the last trimester and after birth. The objective of this study was to test the effects of stress hormones on myoblast proliferation rates. L6 cells and primary myoblasts that were isolated from IUGR fetal sheep in a previous study were used to study the effects of stress hormones on myoblast proliferation and myoblast gene expression. Incubation in epinephrine-spiked media …

Mitigation Of Ergot Vasoconstriction By Clover Isoflavones In Goats (Capra Hircus), Glen E. Aiken, Michael D. Flythe, Isabelle A. Kagan, Huihua Ji, Lowell P. Bush

Ergot alkaloids produced by a fungal endophyte (Epichloë coenophiala; formerly Neotyphodium coenophialum) that infects tall fescue (Lolium arundinaceum) can induce persistent constriction of the vasculature in ruminants, hindering their capability to thermo-regulate core body temperature. There is evidence that isoflavones produced by legumes can relax the vasculature, which suggests that they could relieve ergot alkaloid-induced vasoconstriction and mitigate the vulnerability to severe heat stress in ruminants that graze tall fescue. To test if isoflavones can relieve alkaloid-induced vasoconstriction, two pen experiments were conducted with rumen-fistulated goats (Capra hircus) to determine with ultrasonograpy if …
