Abstract: Systems and methods for automatically delivering a dose of pharmaceutical liquid to an animal includes electronic control to automatically obtain dose information for the animal, electronic control to deliver a volume of pharmaceutical liquid to the animal in response to the dose information; and automatically recording a detailed audit trail of the liquid delivery to the animal. The dose information may be a function of a stored value of at least one physical parameter of the animal. The detailed audit trail may include, for example, information about the amount of liquid actually delivered to the animal, specifying the time of delivery, whether there were any problems with the delivery, and if so, information about such.
