. Agri-news. Agriculture. June 13, 1988 For immediate release 7 Poison plants can be a threat to livestock With dry conditions forcing cattle to search out any kind of food that even looks green this year, farmers should check pastures for noxious weeds that may cause illness and death in livestock, says an Alberta Agriculture specialist. Dr. Roy Smith, a toxicology lab scientist in Edmonton, says because of the poor pasture conditions in some parts of the province this year, cattle may be forced to concentrate in areas where poisonous plants are commonly found. "Every year the toxicology laboratory finds evidence of plant poisons in connection with multiple losses of cattle," says Smith. "Only a handful of plant species are involved but these occur over and over again. Three of the more common plants that are very dangerous to cattle include water hemlock, larkspur and death ; The specialist has provided a brief description of each plant: Water hemlock, number one on the list of plants dangerous to cattle, is responsible for more cattle losses than any other plant in Alberta. Water hemlock, as the name implies, likes water and grows on the banks of creeks, sloughs and other low areas. Water hemlock grows to a height of several feet and has toothed leaflets. The roots are the most toxic part. If a suspect plant is pulled out of the ground and the root cut open a bright yellow oil is found. The root is hollow with several chambers. Because there are other plants that closely resemble water hemlock, a sample plant should be send for analysis, particularly if there have been livestock losses.
