Improved insemination systems particularly adapted to use for sex-selected sperm sorting include systems which achieve superovulation and then multiple embryo production with sexed embryos. These systems combine with other techniques, including techniques for enhanced sheath fluid and other strategies which minimize stress on the sperm cells, and, potentially, a 2.9 percent sodium citrate sheath solution for bovine species and a hepes bovine gamete media for equine species. Improved collection systems and techniques for the process are described so that commercial application of sperms samples as well as the resulting animals may be achieved.

A method for the simultaneous determination of the total concentration of sperm cells and the proportion of live sperm cells in a semen sample is provided. By selective staining of live, dead and/or dying sperm cells, for example using one or more fluorochromes, the detection means can distinguish between live, dead and/or dying sperm cells, for example by detection of the fluorescent response from the sperm cells. The selective staining may be performed at room temperature and in concentrations below standard concentrations. The determination may be performed by selective counting of cells of each fluorescent quality for example by using a flow cytometer having internal concentration standard means. Furthermore, the likelihood of fertilizing a female animal with an insemination dose, taken from a semen sample having a known total concentration of sperm cells and a known proportion of live sperm cells, is predicted on the basis of the thus determined total concentration of sperm cells and the proportion of live sperm cells.

An improved animal-use artificial inseminator comprised of an insemination tube with a nozzle at its front extremity into which an insemination sheath is inserted and a connector at the rear extremity of the insemination tube having a check membrane. After the insemination tube penetrates the female animal body vagina and the front end of the nozzle is nominally at the first cervical ring of the cervix, the semen bottle insertion tube is utilized to pierce the connector check membrane at the rear extremity of the insemination tube and when the semen at the insemination tube is squeezed, semen is automatically squeezed out of the insemination sheath. The soft insemination sheath proceeds along the cervix without the occurrence of friction, the front end smoothly moving forward until it reaches the position of the womb. Contractions of the womb are utilized to articulate the insemination sheath such that the contained semen is ejaculated into the two Fallopian tubes or the womb from the slits along the two sides of the front end. At the same time, after the semen bottle is pulled out, since the connector check membrane automatically opens and closes along with the contraction of the womb, not only is the semen in the insemination sheath prevented from backflow or leakage, but air is admitted for smooth and complete squeezing into the Fallopian tubes or the womb.

The present invention includes methods and apparatus for producing and using an improved artificial insemination device that prevents contaminants from entering the opening at the end of an insemination sheath during insertion through the reproductive tract. A thin protective cover or membrane is provided at the tip of the sheath to seal it, the membrane being designed to rupture under the pressure from the seminal fluid being applied by the plunger used to eject the semen from the insemination gun. The protective cover can be an integrated portion of the sheath itself, or a material applied to the tip of the sheath. The protective cover is minimal in size as to not increase the diameter of the artificial insemination device so that there is no loss in tactile sensitivity to the breeder who must maneuver the invention through the reproductive tract.

The invention relates to a method of producing a protein of interest, comprising making a non-human transgenic mammal that produces said protein in its milk, obtaining said milk from the non-human transgenic mammal and purifying said protein of interest from the milk. Transgenic bovine animals were generated, which are able to produce human growth hormone in mammary glands. The method involves cloning of a genetic construct encoding hGH gene and beta casein promoter conveniently in an expression vector. It also includes transfection procedures into fetal bovine somatic cells, generally fibroblasts, and the nuclear transfer into enucleated bovine oocytes, generating thus transgenic embryos. The method also includes other procedures to generate transgenic embryos for the further expansion of the transgenic herd, such as the subcloning of transgenic female bovines, the superovulation of transgenic cows and their insemination with semen from a non-transgenic or a transgenic male bovine, and the superovulation of non-transgenic cows and their insemination with semen from a transgenic male bovine. Afterwards, transgenic embryos give rise to transgenic cattle that produce human growth hormone in huge amounts in their milk, from which the hormone is completely purified and analysed to fulfill all the requirements for the manufacture of a pure biopharmaceutical product.
