摘要:
The invention relates to methods of increasing genetic merit of swine by establishing a plurality of mating subtypes for a line of swine, and determining a percentage of progeny that are male for each of the mating subtypes, or a percentage of progeny that are female for each of the mating subtypes, that would result, relative to a control, in an increase in genetic merit in the line; the invention further relates to sorting a sperm cell sample from a male swine in one of the mating subtypes into one or more subpopulations of sperm cells, wherein a majority of sperm cells in a subpopulation of sperm cells bear X chromosomes or Y chromosomes, and inseminating one or more female swine in the one of the mating subtypes with the subpopulation of sperm cells to achieve the percentage of progeny that are male, or the percentage of progeny that are female, determined to increase genetic merit relative to the control.

The invention relates to methods of increasing the genetic progress of a line, breed or herd of swine through the use of sex-selected sperm cells in artificial insemination techniques. The invention also encompasses methods of artificially inseminating a swine via deep intrauterine catheter or via a laparoscopic procedure, which allow the use of reduced doses of sex-selected sperm cells.
摘要:
In the preferred embodiment, bovine semen is mixed with a “suitable solution” to form an insemination medium which is injected into the reproductive organs of a female bovine to flood the uterine horns in a nonsurgical AI procedure. The invention includes an AI instrument having a disposable, single use pipette that may be used with this nonsurgical procedure. The AI instrument does not include a balloon and is referred to as “catheter free”. Preferably, the uterine horns are flooded concurrently, but in the alternative, they may be flooded sequentially.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

摘要:
The present invention includes methods and apparatus for depositing materials in the reproductive tract of an animal, such as antibiotics or semen for artificial insemination, using an improved device that covers the end of a sheath inserted into the reproductive tract. A thin protective membrane is provided at the tip of the sheath having a tiny pre-ruptured prick opening therein that is designed to rupture under increased pressure from the fluid inside the sheath. 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 sheath so that there is no loss in tactile sensitivity to a physician or breeder who must maneuver the invention through the reproductive tract of the animal.

The present invention includes apparatuses for artificially inseminating animals which prevents contaminants from entering the opening at the end of an insemination sheath during insertion through the reproductive tract of an animal. 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 animal's reproductive tract.
