Agriculturally grown plants are potentially contaminated with poisonous weeds. Many potentially toxic plants are found in pastures and crops. Consequently, forage crops at harvest or when directly grazed may contain toxic amounts of poisonous plants. Unfortunately, efficient prevention of contamination with certain poisonous plants is not always feasible or practical, and thus, contaminated fee...
to a general description of poisonous animals, to their classification and to their physiological anatomy. It then deals with the habits of poisonous snakes and the methods by means of which they are captured and treated when in captivity. It ends with a complete description of the different species of these reptiles and their geographical distribution. This classification is founded on the des...
Species-specific identification of the major cooked and fresh poisonous mushrooms in Japan was performed using a real-time PCR system. Specific fluorescence signals were detected, and no nonspecific signals were detected. Therefore, we succeeded in developing a species-specific test for the identification of poisonous mushrooms within 1.5 h.
Poisonous weeds are a serious threat to cattle in countries where animals are fed on natural as well as planted pastures. These may cause slight to severe lesions to different organs and, ultimately, death depending on the toxic principle and amount of ingested plant material. Wedelia glauca (Ort.) Hoffm. ex Hicken (Asteraceae) is a perennial plant from South America present in Southern Brazil,...
Risk of livestock losses to poisonous plants can be reduced on many ranges through prudent management based on application of existing knowledge. Poisonous plants can be categorized using both acceptability to livestock and a plant's toxic potential. Acceptability encompasses forage qualities such as taste and chemistry (i.e., nutrient and toxin concentrations) and postingestive feedback from a...
