1. A machine for filling artificial insemination straws with semen, comprising: a hopper configured to store empty straws;a straw-filling station;a transport device provided with elements configured to receive and hold the straws, wherein the transport device is configured to convey straws taken from the hopper and to present the straws taken from the hopper to the filling station, wherein the machine is adapted for processing at least two categories of straws having different diameters, wherein said elements are subdivided into at least two distinct series which can be selectively employed, the elements of one of the two series conforming to adapt to large-diameter straws and the elements of the other of the two series conforming to adapt to small-diameter straws, wherein said transport device is an endless transporter having the elements of both of the at least two series; anda control and command circuit configured to initiate use of the elements of one of the one and the other of the two series while the elements of the other of the one and the other of the two series are inactive during conveyance of the straws. 2. The machine as claimed in claim 1, wherein each of the at least two series of elements comprises a plurality of groups formed from a certain number of adjacent elements of the same respective series, wherein the groups of the one of the two series of elements alternate with the groups of the other of the two series of elements, andwherein the filling station is designed to simultaneously fill a batch of straws supported by a group from the plurality of groups. 3. The machine as claimed in claim 2, wherein the groups of the at least two series of elements each have the same number of respective elements. 4. The machine as claimed in claim 2, wherein said elements are grooves or notches in which the straws are fitted. 5. The machine as claimed in claim 4, wherein axle spacing between the grooves or the notches is constant over an entire length of the transporter, and independent of its respective series. 6. The machine as claimed in claim 1, further comprising an electric motor controlled by the control and command circuit, wherein the motor is configured to operate step by step such that the transport device is capable of being driven with successive and repeated phases of advance, the phases of advance comprising a low pitch, a high pitch of an amplitude multiple to that of the low pitch, and a stop phase. 7. The machine as claimed in claim 1, wherein the transport device is a rotating barrel placed at an outlet of the hopper, wherein the barrel comprises two coaxial discs integral with one another, and wherein the barrel bears said elements. 8. The machine as claimed in claim 1, wherein said hopper comprises means for distributing straws one by one, which are synchronized with an advance of the transport device. 9. The machine as claimed in claim 1, wherein said hopper is removable and comprises means for identification of a category of the straws contained within the hopper, and wherein the machine further comprises a detection device configured to cooperate with said identification means during placement of the hopper so as to automatically determine the category of the straws contained within the hopper. 10. The machine as claimed in claim 9, wherein said detection device is connected to the control and command circuit, wherein the control and command circuit is configured to control a drive motor, andwherein the control and command circuit is configured to index a position of the motor on startup, such that elements corresponding to the category of the straws contained within the hopper are active, the elements not corresponding to the category of the straws contained within the hopper being inactive. 11. The machine as claimed in claim 1, further comprising another station placed upstream of the straw-filling station, wherein straws to be filled at the straw-filling station have distal and proximal ends, the distal ends being blocked by an initially porous stoppers that are capable of becoming watertight when the stoppers are soaked in a liquid,wherein the another station is adapted to introduce a small quantity of non-spermicidal and non-adherent liquid into the straws to be filled at the straw-filling station via the proximal end. 12. The machine as claimed in claim 11, further comprising an ultrasound welding station for the proximal ends of straws filled at the straw-filling station, located downstream of the straw-filling station. 13. The machine as claimed in claim 12, wherein the welding station comprises a sonotrode connected to an anvil, the sonotrode and anvil being provided with complementary indentations for gripping the proximal ends of the straws filled at the straw-filling station, the indentations being subdivided into two alternating groups adapted to weld the small-diameter straws and large-diameter straws, respectively, and wherein the welding station comprises a control member configured to shift the sonotrode and the anvil together in order to make one of the two alternating groups active, and the other of the two alternating groups inactive, as a function of the category of straws to be processed. 14. The machine as claimed in claim 12, wherein the transport device comprises a rotating barrel placed at an outlet of the hopper, wherein the barrel comprises two coaxial discs integral with one another, the discs having notches at their periphery for receiving and holding straws,wherein the machine further comprises two fixed ramps profiled in such a way that one of the two ramps ensures extraction of the proximal ends of the straws from the notches of one of the two discs, just before the straws arrive at the welding station and the other of the two ramps ensures extraction of the distal ends of the straws from the notches of the other one of the two discs, after the straws have left the welding station such that the filled and welded straws fall into a receptacle. 15. The machine as claimed in claim 1, wherein straws to be filled at the straw-filling station have distal and proximal ends, the distal ends being blocked by stoppers initially permeable to air, but capable of becoming watertight when the stoppers are soaked in a liquid, wherein said straw-filling station comprises means for introduction of semen at the proximal end and means for suctioning semen at the distal end through the stoppers. 16. The machine as claimed in claim 1, wherein the transport device comprises a rotating barrel placed at an outlet of the hopper, the barrel comprising two coaxial discs integral with one another, wherein mutual clearance of the two discs is substantially less than a length of the straws, and each of the two discs comprise 64 notches at their periphery for receiving and holding straws,wherein each notch of the two discs comprises a substantially semi-circular base wall and a flared mouthpiece facilitating centering of the straws,wherein said notches of each disc are subdivided into two series of 32 notches, one series of 32 notches being large notches for receiving the large-diameter straws having an external diameter of an order of 3 mm, and the other series of 32 notches being small notches for receiving the small-diameter straws having an external diameter of an order of 2 mm,wherein each of the two series of notches is distributed into eight groups of 4 notches, the 4 groups of large notches alternating with the 4 groups of small notches,wherein an axle spacing between two adjacent notches being constant over the entire periphery of each disc and independent of the series of notch concerned, the axle spacing being of an order of 10 mm. 17. The machine as claimed in claim 1, wherein the elements are subdivided into the at least two distinct series which can be selectively employed such that both series of elements remain on the transport device during processing of straws, regardless of which category of straws is being processed. 18. The machine as claimed in claim 1, wherein the control and command circuit is configured to control a drive motor, and wherein the control and command circuit is configured to index a position of the motor on startup, such that the elements of the one of the one and the other of the two series are active while the elements of the other of the one and the other of the two series are inactive during conveyance of the straws.
