Abstract
A bolus for delivery of pulsed doses of biologically active material to a ruminant comprises a series of distinct and separate bolus elements. Each bolus element is constructed of a degradable outer sheath and a core of biologically active material. The elements are adapted to separate following administration to the ruminant, and to disperse in the rumeno-reticular sac. In due course the elements degrade or corrode to release the biologically active material. Example boli include bolus elements of different respective corrosion characteristics and, as such, are capable of releasing pulsed doses of the active material to the ruminant.
