A method is for determining the quality of an animal's semen. The method includes the steps of collecting at least one fresh or frozen semen sample, and measuring at least one absorption spectrum X.sub.j of at least one sample of the semen. The sample is collected to a straw for artificial insemination with animal semen obtained by implementing the method. A computer and software are used for the implementation of the method.

The invention relates to a method for increasing the lifespan of animal sperm comprising contacting said sperm with an inhibitor of Slo3 potassium channel. The invention also relates to a use of an inhibitor of Slo3 potassium channel, for increasing the lifespan of animal sperm or motility of capacitated animal sperm, comprising contacting an inhibitor of Slo3 potassium channel with said sperm. Moreover, the invention relates to an artificial insemination instrument for use in artificial insemination of an animal, comprising animal sperm in contact with an inhibitor of Slo3 potassium channel. The invention also relates to a method for artificially inseminating an animal using said artificial insemination instrument. Eventually, the invention relates to a method for increasing the fertility of an animal, comprising contacting sperm of said animal with an inhibitor of Slo3 potassium channel; then artificially inseminating said animal with said sperm.

A device for artificially inseminating a mammal with sperm from a male breeding animal is disclosed, the sperm being introduced through the vagina of the animal into or onto the uterus of the animal which is to be inseminated. The device comprises a tube which can be moved on the uterus through the vagina of the animal which is to be inseminated, and a heatable chamber for accommodating a thin tube containing the sperm, and a drive for removing the sperm from the thin tube and the uterus-sided opening of the tube. The device comprises a mechanism enabling the thin tube to be moved out from the chamber into the tube.

A device for collecting uterine fluid is described which can be used in vivo in both animals and humans, without said use causing dilution of fluid components or damage to the endometrium.

A device for collecting uterine fluid is described which can be used in vivo in both animals and humans, without said use causing dilution of fluid components or damage to the endometrium.

The present invention relates to compositions comprising low sugar media, the methods of using these compositions to reduce trauma and stress on processed animal sperm, the resulting sperm and embryo products, and the methods of use of these products to increase the quality, quantity and viability of progeny and improved rates of births in animals.

The assembly comprises a ramp (4) and a straw transfer device (60) comprising two lateral pads and a straw (1) collector arranged between the two lateral pads, the freezer ramp (4) and the transfer device (60) being configured to allow a first end position, to allow a second end position, and such that, by sliding the transfer device (60) from the first end position to the second end position with the pads that slide on angled sections (19) of the ramp (4), the plurality of straws (1) initially arranged on the ramp (4) is recovered in the collector of the transfer device (60).

The present disclosure relates to a radio-frequency identification system for a cryogenic straw comprising: at least one integrated circuit configured to store information and generate a radio-frequency signal in a frequency range of between 30 MHz and 3 GHz; and at least one antenna comprising a conductive thread configured to be integrated, such as molded, into a sidewall of the cryogenic straw. The disclosure further relates to a cryogenic straw comprising at least one antenna, the antenna comprising a conductive thread or rod, wherein the at least one antenna is integrated, such as molded, into a sidewall of the cryogenic straw.

The artificial insemination device for animals comprises a cannula (1); an insertion tip (2) placed on one of the ends of the catheter (1), said insertion tip (2) having one or more holes (7); and a fixing element (3) placed on a cannula (1), wherein said fixing element (3) comprises a tubular portion (8), a first frustoconical portion (4) and a second frustoconical portion (5). The artificial insemination device for animals according to the present invention enables, by not disturbing or hyperstimulating the animal, the cannula to reach the uterus and be fixed in the correct position in order to suitably perform post-cervical insemination in young sows.

Assembly for handbag multiple straws for packaging animal semen, each having a predetermined diameter and a predetermined length, comprising a freezing ramp (4) that has a rim and a bottom surrounding a central free space (5), said bottom comprising two toothed walls (11, 25) which extend longitudinally along said central free space (5), each torn lied wall (11.25) having a toothing at its top, the toothings of said toothed walls (11, 25) being identical, with each trough being delimited by a surface having a curvature along said predetermined diameter, characterized in that it further comprises a crosspiece (100) comprising parts (103, 104) that are able to move with respect to one another and are configured to permit a position in which said crosspiece (100) is removably joined to said freezing ramp (4) at a location provided to receive at least one said straw (1).
