Sheep breed differences in pentobarbitone sleeping-time and response to experimental sporidesmin intoxication

Abstract

Abstract The relative susceptibilities of different breeds of sheep to experimental sporidesmin poisoning and pentobarbitone narcosis were compared. Merinos were significantly more resistant to sporidesmin poisoning than the other breeds (Romney, Border Leicester and Border Leicester-Romney cross). The pentobarbitone sleeping-times of the same Merinos, and of two other groups of Merinos, were significantly shorter than the other breeds.
