ABSTRACT:
Method of artificially inseminating a plurality of animals with aliquots of sperm obtained from a breeding stock individual of that species, obtained by fractionating the collected semen into first and second motile-sperm containing fractions, the first of which is free from immotile sperm and non-sperm components, both suspended in a liquid vehicle which is physiologically acceptable to the sperm and for artificial insemination; dividing the first and second fractions into a plurality of aliquots, each of which contain enough motile sperm to ensure a pregnancy when used for an artificial insemination; artificially inseminating a plurality of individuals of that species in which a predominance of male offspring is desired with the aliquots of the first fraction; and artificially inseminating a plurality of individuals of that species in which a predominance of male offspring is not a desired objective with the aliquots of the second fraction.
