Abstract
With the aim of protecting pig seminal material which may be used for artificial insemination from degradation, herein described are microcapsules containing: a) a liquid nucleus containing a suspension of pig seminal material and a biodegradable and/or biocompatible polymer; b) a film consisting of an alginate of a bivalent or trivalent metal, possibly cross-linked. These microcapsules containing the spermatozoa make it possible to obtain a prolonged and controlled release of seminal material and in addition a protection of the material from degradation, thus enabling a simplification in the procedures of artificial insemination and an increase in pig fertility
