Definitions
- the present invention relates to animal semen reserves, for single use, intended for the artificial insemination of farmed birds such as turkeys, hens, and guinea fowls, of the type constituted by a tube having a light of relatively small diameter so that the semen introduced into it can be kept there by capillary action in order to avoid the use of any plug.
- the semen is generally introduced therein by pressure and it is put in place after introduction of an end into the vagina and the uterus of the animal, by blowing using a pressure organ-such as a pear.
- catheters which have a wall thickness very much greater than the diameter of the lumen, which can reach twice this, and which are consequently extremely rigid, and therefore have the drawback to risk injuring, in a very large number of cases, the internal mucosa of the animal, all the more so as the edge of the front end of such a catheter is generally relatively sharp or sharp, and therefore aggressive, even if this end has been run in.
- catheters generally made of polystyrene
- These catheters are excessively rigid and therefore do not make it possible to compensate for the possible brutality, even involuntary, of the person who uses it, so that one can, in this case, cause irritation and even hematomas of the cloaca mucosa which are very serious, as it greatly reduces the animal's fertility.
- the interior light is perfectly straight, at the slightest mechanical shock during handling in poultry houses, one or more drops of semen fall to the ground or in the hand, during the filling of these catheters, which results in a loss notable in a matter which is relatively precious, in particular in the case where the donor is an animal selected for its qualities, which leads to a considerable and unnecessary operating financial deficit.
- the invention aims to provide a seed reserve of the type considered which avoids any involuntary loss of material.
- a reserve of the type constituted by a tube made of a relatively flexible material and having a seed receiving lumen whose diameter is significantly greater than the thickness of the cylindrical wall, one of the ends of this tube ending in a flange formed by the end of the wall folded back inside the tube, characterized in that this flange is shaped so that its free edge comes into direct contact with the current cylindrical wall of the tube.
- the piston-forming element serves both by its backward movement during the aspiration of the semen inside the flake tube, and by its forward movement during the expulsion of this seed during the insemination itself.
- the means of displacement of the piston in one and the other of these suction and expulsion movements can be of mechanical type (pistol rod), hydraulic or pneumatic.
- the piston constitutes a permanent intermediate element between the means or agent for sucking and expelling the semen, and this semen itself, so that there is therefore no risk of contamination. of it.
- this piston allows a complete expulsion of the semen in the cesspool of the birds during the forward movements towards the hem, and generates, moreover, a phenomenon of aspiration in the manner of a syringe, when 'he backs up.
- the end of the piston which is turned towards the rim of the tube can present on its periphery a profile which matches, at least approximately, that of this converging inner part. Therefore, during the expulsion of the seed, this end of the piston comes to bear closely on the inner part of the rim without leaving practically any free space, so that the seed is expelled entirely without also any loss during insemination, which is added to the absence of loss during handling indicated above.
- said end of the piston may have a frustoconical shape.
- the means for sucking and discharging the seed comprise a push rod
- the reserve represented by the figures is constituted by a single piece, having the shape of a tube 1, which is made of a relatively flexible material, such as polyvinyl chloride, this tube being perfectly cylindrical over its entire length, between its two ends 2 and 3, the common cylindrical wall of this tube having a uniform thickness over this entire length and delimiting an interior lumen 4, intended to receive the seed. and whose diameter is very much greater than the thickness of the cylindrical wall, for example of the order of five to ten times the latter.
- a tube 1 which is made of a relatively flexible material, such as polyvinyl chloride
- This tube ends in a rim 5 which is formed by a fold back of the end of the current wall of this tube, this rim being folded inside the tube, over a length which, in the direction axial, is for example of the order of half the internal diameter of the lumen 4.
- This rim 5 is shaped so that its free edge 6 comes into direct contact with the current cylindrical wall of the tube, and the section of this rim has over its entire length between the end 3 and its free edge 6, a continuous concavity, that is to say without bending or sharp angle, on the contrary having a uniform rounding, both on its edge which faces outwards and on the entire part located inside the tube.
- This section of the rim advantageously has the shape of a half-oval, or any approaching shape, so that the profile offered by the entire rim is similar to that of a trumpet or a venturi.
- this rim successively has, in the axial direction and from the inside towards the free end 3 of the tube, first a convergent part 5a which ends internally by the rim 6, then then, a divergent part 5b which is connected by a fillet with the corresponding end 3 of the tube 1.
- Such a reserve can thus receive a column of animal seed 7, the outer meniscus of which rests on the converging part 5a of the rim.
- the seed column is maintained towards the inside of the tube, even in the event of an impact, while on the contrary, when an air pressure is applied to the opposite end, when an inseminate tion must be carried out, once the seed column 7 engaged inside the rim 5, its total expulsion outside the tube can be favored by the divergent 5b without any part being likely to remain inside .
- a piston member 8 which comprises at its end which faces the rim 5 of the tube, a projecting head 8a which has a frustoconical shape converging towards the rim 5, and extending towards the rear by a short circular section 8b connecting to the body of the piston 8c by an annular recess 8d.
- the profile presented by the periphery of this head approximates that of the converging inner part .5a of the rim. There is therefore practically no free space between this head 8a of the piston and this rim 5 when the piston approaches it.
- This head 8a and more particularly its annular section 8b, has an outside diameter corresponding, without play, to the inside diameter of the tube 1, so as to be slidably mounted in a sealed manner in this tube.
- This shoulder 8b is connected with the body 8c, which is formed of a cylindrical part, the diameter of which is less than the inside diameter of the tube 1 and inside which a blind axial hole 8c is formed.
- a seed column 7 fills this tube by bearing, by its two extreme menisci 7a and 7b J on the one hand, on the converging inner part 5a of the rim and, on the other hand, on the head 8a of the piston.

Abstract
Description
La présente invention concerne les réserves de semence animale, à usage unique, destinées à l'insémination artificielle des oiseaux d'élevage tels que les dindes, poules, et pintades, du type constitué par un tube présentant une lumière de diamètre relativement faible pour que la semence qui y est introduite puisse y être maintenue par seule capillarité afin d'éviter l'usage de tout bouchon. La semence y est en général, introduite par pression et elle est mise en place après introduction d'une extrémité dans le vagin et l'utérus de l'animal, par soufflage à l'aide d'un organe de pression-tel qu'une poire. Ces tubes sont jetés après l'emploi afin d'éviter toute contamination, de sorte qu'ils sont dimensionnés de manière à ne contenir qu'une dose unique de semence, prévue néanmoins suffisante pour assurer une insémination efficace, par exemple de 15 à 50 mm3 seulement suivant les espèces animales, ce qui explique le possibilité de maintien par simple capillarité. L'absence de bouchon simplifie considérablement la manipulation dans le cas où la paillette doit être utilisée pour l'insémination dès son remplissage, sans stockage intermédiaire.The present invention relates to animal semen reserves, for single use, intended for the artificial insemination of farmed birds such as turkeys, hens, and guinea fowls, of the type constituted by a tube having a light of relatively small diameter so that the semen introduced into it can be kept there by capillary action in order to avoid the use of any plug. The semen is generally introduced therein by pressure and it is put in place after introduction of an end into the vagina and the uterus of the animal, by blowing using a pressure organ-such as a pear. These tubes are discarded after use in order to avoid any contamination, so that they are dimensioned so as to contain only a single dose of semen, provided nevertheless sufficient to ensure effective insemination, for example from 15 to 50 mm3 only depending on the animal species, which explains the possibility of maintenance by simple capillarity. The absence of a plug considerably simplifies handling in the event that the straw should be used for insemination as soon as it is filled, without intermediate storage.
On connait déjà des réserves de ce type, dites cathéters, qui présentent une épaisseur de paroi très fortement supérieure au diamètre de la lumière, pouvant atteindre le double de celui-ci, et qui sont par conséquent extrêmement rigides, et présentent donc l'inconvénient de risquer de blesser , dans un très grand nombre de cas, la muqueuse interne de l'animal, d'autant que le bord de l'extrémité avant d'un tel cathéter est en général relativement tranchant ou aigu, et donc agressif, même si cette extrémité a été soumise à un rodage. Ces cathéters, en général réalisés en polystyrène, sont excessivement rigides et ne permettent donc pas de compenser la brutalité éventuelle, même involontaire, de la personne qui l'utilise, de sorte que l'on peut, dans ce cas, provoquer une irritation et même des hématomes de la muqueuse du cloaque qui sont très graves, car réduisant fortement la fertilité de l'animal. De plus, du fait que la lumière intérieure est parfaitement rectiligne, au moindre choc mécanique pendant les manipulations dans les poulaillers, une à plusieurs gouttes de semence tom- bentàterre ou dans la main, pendant le remplissage de ces cathéters, ce qui entraine une perte notable en une matière qui est relativement précieuse, notamment dans le cas où le donneur est un animal sélectionné pour ses qualités, ce qui entraîne un déficit financier d'exploitation considérable et inutile.Reserves of this type are already known, called catheters, which have a wall thickness very much greater than the diameter of the lumen, which can reach twice this, and which are consequently extremely rigid, and therefore have the drawback to risk injuring, in a very large number of cases, the internal mucosa of the animal, all the more so as the edge of the front end of such a catheter is generally relatively sharp or sharp, and therefore aggressive, even if this end has been run in. These catheters, generally made of polystyrene, are excessively rigid and therefore do not make it possible to compensate for the possible brutality, even involuntary, of the person who uses it, so that one can, in this case, cause irritation and even hematomas of the cloaca mucosa which are very serious, as it greatly reduces the animal's fertility. In addition, due to the fact that the interior light is perfectly straight, at the slightest mechanical shock during handling in poultry houses, one or more drops of semen fall to the ground or in the hand, during the filling of these catheters, which results in a loss notable in a matter which is relatively precious, in particular in the case where the donor is an animal selected for its qualities, which leads to a considerable and unnecessary operating financial deficit.
On connait également d'autres réserves de ce type, dites paillettes, dont l'épaisseur de paroi est nettement plus faible, ce qui entraine par ailleurs, une réduction importante du diamètre extérieur (de l'ordre de-grandeur de la moitié de celui des cathéters ci-dessus), de sorte que ces paillettes sont beaucoup plus flexibles, peuvent se plier et ne pas casser , et, en tout état de cause, permettent de nuancer ou d'éliminer les effets néfastes des mouvements trop énergiques de l'opérateur. A cela s'ajoute comme avantage, le fait qu'en début de ponte, chez les animaux jeunes, le cloaque de l'oiseau, relativement contracté, risque moins d'être blessé en raison du diamètre notablement plus faible d'une telle paillette.We also know other reserves of this type, called flakes, whose wall thickness is significantly smaller, which also leads to a significant reduction in the outside diameter (of the order of magnitude by half that of the above catheters), so that these flakes are much more flexible, can bend and not break, and, in any event, allow to nuance or eliminate the harmful effects of the too energetic movements of the operator. Added to this is the advantage, that at the start of laying, in young animals, the cloaca of the bird, relatively contracted, is less likely to be injured because of the significantly smaller diameter of such a flake. .
Ces réserves connues présentent toutefois, afin d'offrir un bord arrondi ne blessant pas à l'introduction, un rèbord de même épaisseur que la paroi et réalisé par pliage de celle-ci, et revenant vers l'intérieur du tube, parallèlement à la paroi principale de celui-ci, de manière à constituer une section en U, ce rebord ou ourlet s'étendant axialement sur une longueur de l'ordre de grandeur du diamètre de la lumière.These known reserves have, however, in order to offer a rounded edge which does not injure the introduction, a rim of the same thickness as the wall and produced by folding the latter, and returning towards the inside of the tube, parallel to the main wall thereof, so as to constitute a U-shaped section, this rim or hem extending axially over a length of the order of magnitude of the diameter of the lumen.
Il se trouve néanmoins que ces réserves, ou paillettes, déjà perfectionnées, présentent encore divers inconvénients. C'est ainsi, en particulier,que, du fait de la section en U précitée, une partie de la semence contenue dans la paillette ne peut pas être éjectée par l'orifice d'expulsion délimité par le rebord considéré, de sorte qu'elle s'accumule en forme d'anneau entre l'extrémité de ce rebord et la paroi principale, et est donc totalement perdue pour l'opération d'insémination, entraînant ainsi un déficit financier. De plus, lors d'un choc, il se présente encore un risque d'expulsion de semence en-dehors du tube, une goutte pouvant tomber au sol et entraîner,là encore, une perte en matière.However, it turns out that these reserves, or flakes, already perfected, still have various drawbacks. Thus, in particular, because of the aforementioned U-shaped section, part of the semen contained in the straw cannot be ejected through the expulsion orifice delimited by the rim considered, so that it accumulates in the form of a ring between the end of this rim and the main wall, and is therefore totally lost for the insemination operation, thus causing a financial deficit. In addition, during a shock, there is still a risk of expulsion of semen outside the tube, a drop that may fall to the ground and cause, again, a loss of material.
C'est pourquoi l'invention a pour but de fournir une réserve de semence du type considéré qui évite toute perte involontaire de matière.This is why the invention aims to provide a seed reserve of the type considered which avoids any involuntary loss of material.
A cet effet, elle a pour objet une réserve du type constitué par un tube réalisé en une matière relativement souple et présentant une lumière de réception de semence dont le diamètre est nettement supérieur à l'épaisseur de la paroi cylindrique, l'une des extrémités de ce tube se terminant par un rebord constitué par l'extrémité de la paroi repliée à l'intérieur du tube, caractérisée en ce que ce rebord est conformé de manière que son bord libre vienne au contact direct de la paroi cylindrique courante du tube.For this purpose, it relates to a reserve of the type constituted by a tube made of a relatively flexible material and having a seed receiving lumen whose diameter is significantly greater than the thickness of the cylindrical wall, one of the ends of this tube ending in a flange formed by the end of the wall folded back inside the tube, characterized in that this flange is shaped so that its free edge comes into direct contact with the current cylindrical wall of the tube.
Grâce à cet agencement, lors de l'expulsion volontaire de la semence pour une insémination, aucune partie de la semence n'est retenue dans la paillette, évitant ainsi toute perte onéreuse. En outre, du fait de la forme, analogue à celle d'une trompette ou d'un venturi, que présente le rebord intérieur, il y a,d'une part, retenue de la colonne de semence au niveau de la partie convergeant vers l'extérieur, du rebord, lorsqu'aucune pression n'est appliquée à l'autre extrémité du tube, donc en cours de manipulation, de sorte que l'on évite une expulsion de semence que risquerait de provoquer un choc, entrainant la chute d'une ou plusieurs gouttes au sol, et d'autre part, au contraire, facilite l'expulsion totale grâce à la seconde partie divergente du rebord, lorsqu'une pression est appliquée pour l'insémination.Thanks to this arrangement, during the voluntary expulsion of the semen for insemination, no part of the semen is retained in the straw, thus avoiding any costly loss. In addition, due to the shape, similar to that of a trumpet or a venturi, which the inner rim has, there is, on the one hand, retention of the seed column at the level of the part converging towards the outside, of the rim, when no pressure is applied to the other end of the tube, therefore during handling, so that a seed expulsion is avoided which would risk causing a shock, causing the fall of one or more drops on the ground, and on the other hand, on the contrary, facilitates total expulsion thanks to the second divergent part of the rim, when a pressure is applied for insemination.
De manière particulièrement avantageuse, il peut être prévu que, à l'intérieur du tube, et monté coulissant de-manière étanche dans celui-ci, se trouve logé un élément de révolution formant piston.In a particularly advantageous manner, it can be provided that, inside the tube, and mounted to slide in a sealed manner therein, is housed an element of revolution forming a piston.
Grâce à cette disposition, l'élément formant piston sert à la fois, par son mouvement de recul lors de l'aspiration de la semence à l'intérieur du tube-paillette, et par son mouvement d'avance lors de l'expulsion de cette semence pendant l'insémination elle-même. Les moyens de déplacement du piston dans l'un et l'autre de ces mouvements d'aspiration et d'expulsion peuvent être de type mécanique (tige de pistolet), hydraulique ou pneumatique.Thanks to this arrangement, the piston-forming element serves both by its backward movement during the aspiration of the semen inside the flake tube, and by its forward movement during the expulsion of this seed during the insemination itself. The means of displacement of the piston in one and the other of these suction and expulsion movements can be of mechanical type (pistol rod), hydraulic or pneumatic.
La présence du piston et le maintien qui en résulte de la colonne de semence aspirée, entre celui-ci et le rebord en ourlet, rendent totale la retenue de la semence à l'intérieur du tube, quels que soient les chocs mécaniques, parfois violents, qui peuvent survenir sur le tube lors des multiples manipulations effectuées entre l'aspiration et l'expulsion à l'insémination. Il résulte de cette double sécurité offerte par l'ourlet et par le piston, qu'il ne peut apparaître aucune perte de semence pendant les manipulations, ce qui est essentiel en raison du prix très élevé de la semence en aviculture, notamment pour les oiseaux sélectionnés.The presence of the piston and the resulting support of the suctioned seed column, between it and the hem flange, make the retention of the seed inside the tube total, whatever the mechanical shocks, sometimes violent. , which can occur on the tube during the multiple manipulations carried out between aspiration and expulsion at insemination. It follows from this double safety offered by the hem and by the piston, that there can appear no loss of seed during handling, which is essential because of the very high price of seed in poultry farming, especially for birds. selected.
En outre, le piston constitue un élément intermédiaire permanent entre le moyen ou agent d'aspiration et d'expulsion de la semence, et cette semence elle-même, de sorte qu'il n'existe, de ce fait, aucun risque de contamination de celle-ci.In addition, the piston constitutes a permanent intermediate element between the means or agent for sucking and expelling the semen, and this semen itself, so that there is therefore no risk of contamination. of it.
En effet, la présence du piston et sa parfaite étanchéité avec le tube, évite que,pendant l'insémination, l'air ambiant du poulailler puisse pénétrer dans le tube. En outre, ce piston permet une expulsion complète de la semence dans le cloaque des oiseaux pendant les mouvements d'avance en direction de l'ourlet, et engendre, par ailleurs, un phénomène d'aspiration à la manière d'une seringue, lorsqu'il recule.Indeed, the presence of the piston and its perfect tightness with the tube, prevents that, during the insemination, the ambient air of the hen house can penetrate in the tube. In addition, this piston allows a complete expulsion of the semen in the cesspool of the birds during the forward movements towards the hem, and generates, moreover, a phenomenon of aspiration in the manner of a syringe, when 'he backs up.
Dans un mode de réalisation particulier de l'invention, dans le cas où le rebord du tube présente une partie intérieure convergeant vers la paroi de ce tube, l'extrémité du piston qui est tournée vers le rebord du tube peut présenter sur sa périphérie un profil qui épouse, au moins approximativement, celui de cette partie intérieure convergente. De ce fait, lors de l'expulsion de la semence, cette extrémité du piston vient s'appuyer de près sur la partie intérieure du rebord sans laisser subsister pratiquement aucun espace libre, de sorte que la semence se trouve expulsée en totalité sans également aucune perte pendant l'insémination, qui vient s'ajouter à l'absence de perte pendant la manipulation indiquée plus haut. De préférence, ladite extrémité du piston peut présenter une forme tronconique.In a particular embodiment of the invention, in the case where the rim of the tube has an inner part converging towards the wall of this tube, the end of the piston which is turned towards the rim of the tube can present on its periphery a profile which matches, at least approximately, that of this converging inner part. Therefore, during the expulsion of the seed, this end of the piston comes to bear closely on the inner part of the rim without leaving practically any free space, so that the seed is expelled entirely without also any loss during insemination, which is added to the absence of loss during handling indicated above. Preferably, said end of the piston may have a frustoconical shape.
Avantageusement, dans le cas où les moyens d'aspiration et de refoulement de la semence comprennent une tige de poussée, il peut être prévu que l'extrémité du piston, qui est opposée au rebord du tube, présente un trou axial borgne, ce qui permet à la tige de se sertir dans ce trou et de commander aisément, à la fois le recul et l'avance du piston.Advantageously, in the case where the means for sucking and discharging the seed comprise a push rod, provision may be made for the end of the piston, which is opposite the rim of the tube, to have a blind axial hole, which allows the rod to crimp into this hole and easily control both the recoil and the advance of the piston.
D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre, à titre d'exemple non limitatif, en regard du dessin annexé, sur lequel :

- - fig. 3 shows the same reserve, after aspiration of a seed column in the tube.
La réserve représentée par les figures est constituée par une pièce unique, présentant la forme d'un tube 1, qui est réalisé en une matière relativement souple, telle que du chlorure de polyvinyle, ce tube étant parfaitement cylindrique sur toute sa longueur, entre ses deux extrémités 2 et 3, la paroi cylindrique courante de ce tube présentant une épaisseur uniforme sur toute cette longueur et délimitant une lumière intérieure 4, destinée à recevoir la semence. et dont le diamètre est très nettement supérieur à l'épaisseur de la paroi cylindrique, par exemple de l'ordre de cinq à dix fois cette dernière.The reserve represented by the figures is constituted by a single piece, having the shape of a tube 1, which is made of a relatively flexible material, such as polyvinyl chloride, this tube being perfectly cylindrical over its entire length, between its two
L'extrémité 3 de ce tube se termine par un rebord 5 qui est constitué par un repli de l'extrémité de la paroi courante de ce tube, ce rebord étant replié à l'intérieur du tube, sur une longueur qui, dans le sens axial, est par exemple de l'ordre de la moitié du diamètre intérieur de la lumière 4.The
Ce rebord 5 est conformé de manière que son bord libre 6 vienné au contact direct de la paroi cylindrique courante du tube, et la section de ce rebord présente sur toute sa lonqueur entre l'extrémité 3 et son bord libre 6, une concavité continue, c'est à dire sans pliage ou angle net, présentant au contraire un arrondi uniforme, tant sur sa tranche qui fait face vers l'extérieur que sur toute la partie située à l'intérieur du tube. Cette section du rebord présente avantageusement la forme d'un demi-ovale, ou toute forme approchante, de sorte que le profil offert par l'ensemble du rebord est analogue à celui d'une trompette ou d'un venturi.This
Autrement dit, ce rebord présente successivement, dans le sens axial et de l'intérieur vers l'extrémité libre 3 du tube, d'abord une partie convergente 5a qui se termine intérieurement par le rebord 6, puis ensuite, une partie divergente 5b qui vient se raccorder par un congé avec l'extrémité 3 correspondante du tube 1.In other words, this rim successively has, in the axial direction and from the inside towards the
Une telle réserve peut ainsi recevoir une colonne de semence animale 7, dont le ménisque extérieur vient s'appuyer sur la partie convergente 5a du rebord. Ainsi que précisé plus haut, grâce à la forme de ce convergent, la colonne de semence se trouve maintenue vers l'intérieur du tube, même en cas de choc, tandis qu'au contraire, lorsqu'une pression d'air est appliquée à l'extrémité opposée,lorsqu'une insémination doit être effectuée, une fois la colonne de semence 7 engagée à l'intérieur du rebord 5, son expulsion totale à l'extérieur du tube peut être favorisée par le divergent 5b sans qu'aucune partie ne risque de demeurer à l'intérieur.Such a reserve can thus receive a column of
Comme le montre la fig.2, à l'intérieur du tube se trouve logé un élément formant piston 8, qui comprend à son extrémité qui est tournée vers le rebord 5 du tube, une tête en saillie 8a qui a une forme tronconique convergent vers le rebord 5, et se prolongeant vers l'arrière par une courte section circulaire 8b se raccordant au corps du piston 8c par un décrochement annulaire 8d. Le profil présenté par la périphérie de cette tête épouse approximativement celui de la partie intérieure convergente .5a du rebord. Il n'existe donc pratiquement aucun espace libre entre cette tête 8a du piston et ce rebord 5 quand le piston s'y approche.As shown in fig.2, inside the tube is housed a
Cette tête 8a, et plus particulièrement sa section annulaire 8b, présente un diamètre extérieur correspondant, sans jeu, au diamètre intérieur du tube 1 , de façon à être montée coulissante de manière étanche dans ce tube. Cet épaulement 8b se raccorde avec le corps 8c, qui est formé d'une partie cylindrique, dont le diamètre est inférieur au diamètre intérieur du tube 1 et à l'intérieur de laquelle est menagé un trou axial borgne 8c.This
Lorsque le tube, ainsi muni de son piston en appui contre le rebord 5, est mis en présence d'un volume de semence animale, et que le piston 8 est déplacé, dans un mouvement de recul, vers l'extrémité opposée du tube, une colonne de semence 7 vient remplir ce tube en prenant appui, par ses deux ménisques extrêmes 7a et 7bJd'une part, sur la partie intérieure convergente 5a du rebord et, d'autre part, sur la tête 8a du piston.When the tube, thus provided with its piston in abutment against the
Ainsi, grâce à ce double appui, la colonne de semence se trouve parfaitement retenue à l'intérieur du tube, malgré les chocs auxquels ce dernier peut être soumis (fig.3).Thus, thanks to this double support, the seed column is perfectly retained inside the tube, despite the shocks to which the latter may be subjected (fig. 3).
En outre, lorsque,lors de l'expulsion prévue pour l'insémination, le piston 8 repousse la colonne de semence 7, le volume entier de cette dernière se trouve évacué sans aucune perte, étant donné que la tête tronconique 8a vient s'appuyer très précisément sur le rebord 5, dans la position représentée sur la Fig.2.In addition, when, during the expulsion planned for insemination, the
