siresine

siresine

a type of harness worn over the forequarters by rams and as a headstall in bulls in mating groups. The harness carries a crayon on the brisket or under the chin in bulls so that females which are mounted by the male are marked by the crayon. Different colored crayons are used to identify females mated over a particular period of time or by individual males. This identifies the sire when more than one male is in the group.
