The straw comprises a tube (11) extending between a first end and a second end and comprises a gas-permeable, liquid-tight plug, said plug being arranged in the tube (11) in the vicinity of the first end of same and extending between a first end turned towards the first end of the tube (11) and a second end turned towards the second end of the tube (11). Said plug comprises an element (14) impregnated with multivalent cations (22) at least in the vicinity of a first end turned towards the second end of the tube (11). The system comprises the straw and a liquid medium provided to produce, by mixing, in predefined conditions, the liquid substance (21). The medium contains an alginate (23) in solution.


Patent
Imv Technologies | Date: 2017-01-25

The present invention relates to a composition for use in low dose artificial insemination and to a process for artificial insemination of a female mammal using a dose of sperm originating from a male mammal of the same species that is significantly lower than necessary in the absence of the composition. The preferred female mammal is a sow (sus scrofa), and preferably the composition is for use in artificial uterine insemination, and the process for artificial insemination preferably is uterine insemination.


The invention relates to a straw comprising a tube (11) extending between a first end (13) and a second end (14) and comprising a stopper (12) placed in the tube near the first end thereof and extending between a first end (17) facing the first end of the tube, and a second end (20) facing the second end of the tube, said stopper and said tube being configured such that, after a liquid substance (22) has come in contact with the stopper via the second end thereof, the stopper blocks the passage of the liquid substance therethrough and is, by pushing on the first end thereof, slidable into the tube toward the second end thereof. Moreover, the stopper comprises, on the side of the second end of the tube, a barrier pad (16) consisting of hydrophobic threads over the entire cross-section of the tube.

The system comprises a straw and a liquid dilution medium. The straw comprises a tube (11) extending between a first end and a second end and comprises a gas-permeable, liquid-tight plug, said plug being arranged in the tube (11) in the vicinity of the first end of same and extending between a first end turned towards the first end of the tube (11) and a second end turned towards the second end of the tube (11). Said plug comprises an element (14) impregnated with a reagent (22) at least in the vicinity of a first end turned towards the second end of the tube (11). The liquid medium is provided to produce, by mixing, in predefined conditions, the liquid substance (21). The reagent (22) and the medium(27) are configured such that, when the substance (21) comes into contact with the first end of the impregnated element (14), it forms a hydrogel.


The bag comprises two flexible sheets (11) attached to each other by a weld area delimiting a pouch having a predefined volume when said bag is filled, said pouch being designed to contain a dose (27) of said diluted animal semen having said predefined volume. The surface (30) of each of said flexible sheets (11) faces said pouch (14) which is part of a layer (35) of weldable thermoplastic material. For one or preferably for each of said sheets (11), said layer of weldable thermoplastic material (35) comprises triclosan; and the ratio between said predefined volume of said pouch and the sum of the areas of the surfaces (30) of said sheets (11) facing said pouch is between 0.3 ml/cm2 and 0.5 ml/cm2 . The system comprises such bags and an antibiotic-free dilution medium.


The invention concerns a system for collecting animal semen, comprising a container (3) configured to be mounted on an end (9) of an artificial vagina (2), having an internal space (15) configured to receive said semen and configured to comprise a first dilution extender (5) before receiving said semen, and said system (1) comprises a collecting device (4) configured to be at least partially inserted into said container and to be fastened to said vagina, and being interposed between said vagina and said container, said collecting device comprising a flow channel (23) for said semen extending within said internal space of said container and a discharge aperture (26) for said semen open to said internal space; and said system is configured to prevent, at least for the most part, said first dilution extender from passing in said flow channel of said collecting device.


The straw comprises a tube (11) having a swelling plug (15) provided with a fibrous support agent and a swelling agent combined with the support agent and configured, at least close to a second end (18) of the swelling plug, after a liquid-based substance has come up against its second end, to be in a state of swelling constrained by said tube such that if a first part (26) of the swelling plug of length comprised between 2 mm and 3 mm starting from its second end has come out of the tube via a second end (14) of the tube, whereas a second part of the swelling plug remains in the tube, the first part of the swelling plug becomes decompacted and expands with the second end of the swelling plug which assumes a diameter (d) at least equal to one and a half times the inner diameter of the tube.
