Effects of Poisonous Plants on Livestock documents the proceedings of a U.S.-Australian symposium on the effects of poisonous plants on domestic livestock. The symposium was held at Utah State University in Logan, Utah, on 19-24 June 1977. The volume is organized into eight parts. Part I discusses poisonous plant problems in the United States and Australia. Part II contains papers on general topics such as inorganic toxicants and poisonous plants; the hazard of plant toxicities to the human population; and selenium in plants as a cause of livestock poisoning. Part III examines the effects of simple phytotoxins such as selenium and oxalate on livestock. Part IV focuses on the effects of plant hepatotoxins, including pyrrolizidine alkaloids, Artemisia nova, and Tetradymia spp. Part V deals with plant cardio/pulmonary toxins such as Myoporum spp. and Pimelea spp. Part VI tales up plant neurotoxins while Part VII discusses plant teratogens and toxins affecting reproduction. Part VII presents studies on other toxic substances. It includes studies on oak poisoning and pine needle abortion in cattle.
