  • Title: Physiologic studies of experimentally grain-engorged cattle and sheep.
    Author: Dougherty RW, Riley JL, Baetz AL, Cook HM, Coburn KS.
    Journal: Am J Vet Res; 1975 Jun; 36(6):833-5. PubMed ID: 238439.
    Abstract:
    Seven sheep weighing 34 to 41 kg, each, 3 steers and 1 heifer weighing 230 to 460 kg each, were experimentally, "overfed" (induced grain engorgement). The most significant changes occurred in ruminal ingesta pH, blood pH, packed cell volume (PCV), hemoglobin (Hb), carbon dioxide pressure (PCO2, total CO2 (volume %), blood D-lactic acid, blood HCO3, and base excess. There was no common denominator that was especially pathognomonic.
