The invention encompasses improved catheters comprised of multiple tubular bodies and methods of using them in artificial insemination.

A method of artificially inseminating a hen includes the steps of securing a male bird, applying a semen extender liquid to a tip of a cloacal protuberance of the male bird, squeezing the cloacal protuberance to extract semen from the male bird into the semen extender liquid to form a mixture, applying a tip of a pipette to the mixture, drawing the mixture into the pipette, securing the hen, inserting the pipette into the hen's cloaca, and squeezing a bulb of the pipette to inject the mixture from the pipette into the cloaca. A holding device for restraining a bird during sperm collection and artificial insemination procedures has a base, an arm extending upward from the base, and an open-ended receptacle connected to the upper end of the arm. The holding device is useful in mitigating injury to the bird and the handler during the procedures.

The present invention relates to a method and apparatus for passive collection of sperm having improved motility from a semen sample. The semen sample is contacted with on side of a porous barrier and a nutrient-containing media is contacted with the other side of the porous barrier. More robust sperm migrate from the semen sample through the porous barrier and are collected in a nutrient-containing media.

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.

Bodily fluid collection systems are described where the system may be used for collecting and transferring sperm into a syringe. The syringe is configured to have a distal collection tip which is gently tapered or radiused to present a smooth and atraumatic surface and which is specifically configured and shaped to be inserted within and received by the collection receptacle. The distal collection tip has a shape which corresponds directly to a tapered reservoir defined at the bottom of the collection receptacle such that a distal opening defined through the tip is optimally positioned within the concentrated bodily fluid pooled within the reservoir for collection. Moreover, the gentle taper of the collection tip may present an atraumatic surface for inhibiting damage to the sperm contained within the ejaculate as the sperm is suctioned into the distal opening for insemination into the female.

Biological fluid collection. At least some of the illustrative embodiments are systems including a sleeve of elastomeric material and a receptacle coupled to the sleeve. The sleeve may include: first and second ends, each end comprising respectively a first and a second orifice; and a passage extending between the first and second orifices. The receptacle may include: a side wall and a bottom that define an interior volume and a height; and an entrance portion that defines an internal diameter, wherein the height of receptacle is at least half the internal diameter. The receptacle may mechanically couple to the sleeve such that the interior volume is fluidly coupled to the passage of the sleeve.

An artificial propagation method of Sinocyclocheilus rhinocerous, comprising placing female and male parent fish in a sterilized culture container in which a black cave simulant is placed in advance, strictly controlling the environmental parameters of the parent fish culture. The method realizes natural spawning and sperm production of S. rhinocerous under artificial conditions without using oxytocin. There is no oxytocin used in the artificial propagation, thus not only obtaining a higher fertilization rate and incubating rate, but also reducing the aquaculture cost. The operation is simpler and faster. At the same time, different feeds are fed in different growth stages according to the different growth characteristics of each stage of S. rhinocerous fry, thereby increasing the survival rate and reducing the deformity rate of fries. Therefore, the method provided by the present disclosure realizes efficient artificial propagation method of S. rhinocerous.

The present invention relates to a device and method for collecting semen from boars. The device is characterized in that it has a simple structure and is therefore inexpensive to produce and, during the method, it reduces contamination, in particular the microbe count. The device has a glove (1) with a fingers portion (2) and a thumb portion (3) for receiving a hand and, on one side of the glove (1) between the fingers portion (2) and the thumb portion (3), it has a film tube (5) with an opening (6) which is held open by a spring element (10), and of which the opposite, second end (13) is closed, wherein the film tube (5) is connected to the glove (1).

Provided in the present invention is a sperm extractor with a telescopic function, including: a motor for providing power; a crank mounted on the motor; a connecting rod connected to the crank and an inner container; and the inner container for sperm extraction, where the motor rotates to drive the crank to rotate, and the crank drives the connecting rod to push or pull the inner container for sperm extraction. According to the present invention, the motor rotates to drive the crank to rotate, and the crank drives the connecting rod to push or pull the inner container to make a telescopic motion for sperm extraction; a Hall switch is further disposed on a printed circuit board (PCB) to sense positions of the crank and the connecting rod to control a stop position of the motor, so as to achieve reset.
