Plants Poisonous to Live Stock

"Plants Poisonous to Live Stock" by Harold Cecil Long is a scientific publication written in the early 20th century. This handbook addresses the significant issue of plants that pose dangers to livestock, compiling previously scattered knowledge into a coherent format. It aims to inform farmers, veterinarians, and agricultural experts about the toxic properties of various plants, their symptoms, and the potential economic impact on livestock industries. The opening of the text outlines its purpose, acknowledging a notable lack of accessible reliable information in scientific literature about poisonous plants relevant to livestock. Long emphasizes the economic toll caused by such plants and introduces the complexity of identifying poisonous versus non-poisonous species, which may vary greatly depending on environmental conditions. He establishes the critical relationship between different livestock species and various plants, suggesting that the risk of poisoning can change with the season and circumstances, such as food scarcity. This preface sets the stage for an in-depth study that will follow in the subsequent chapters, which promise detailed descriptions of toxic plants, their effects, and humane management practices to mitigate risks.
