The present invention describes a method of inducing lactation in non-human mammals by using a single administrations of an estrogen compound, a dopaminergic antagonist, and oxytocin. For example, the estrogen compound may be a long acting composition and is administered at least one week before the dopaminergic antagonist. However, the oxytocin administration may be given the day after the dopaminergic antagonist, after which lactation may begin immediately. Preferred compounds may comprise a non-17 estradiol and domperidone. Such an injection protocol may result in the production of commercially viable volumes of milk from prepubescent non-human mammals, such as prepubescent female non-human mammals.

Methods are disclosed for the production of mammalian voltage-gated ion channels in ciliates. In other aspects, compositions comprising lipid bilayers containing mammalian voltage-gated ion channels are disclosed. In other aspects, compositions comprising purified and reconstituted mammalian voltage-gated ion channels are disclosed.

Method for selecting mammalian cells having a genetically-desirable trait, the method comprising culturing an embryo in vitro, dividing the cells from the embryo into aliquots, subjecting the cells from at least one of the aliquots to a genetic analysis, and, based on the results of such analysis, selecting an aliquot of cells. Method for selecting mammalian cells having a genetically-desirable trait, the method comprising culturing an embryo in vitro, transferring the cultured embryo into a recipient female, collecting the embryo, dividing the cells from the embryo into aliquots, subjecting the cells from at least one of the aliquots to a genetic analysis, and, based on the results of such analysis, selecting an aliquot of cells. Method for selecting a mammalian embryo having a genetically-desirable trait, the method comprising removing one or more cells from each of a plurality of embryos, culturing the cells, subjecting the cultured cells to a genetic analysis, and, based on the results of such analysis, selecting an embryo.

Genetic tests, such as whole genome analysis (WGA), have been employed to identify genetically superior embryos. The disclosed methods extend in vitro culture time of embryos while awaiting results of genetic tests being performed on a portion of the same embryos. The disclosed methods also help expand the number of cells in each embryo before implantation in the recipient.
