ABSTRACT:
Small, compact and portable semen straw filling devices are hand operated by a single person.
A single turn of the handle advances a straw for filling and renders the straw removable by a handheld syringe with which an operator may guide the straw into an ovaduct of a turkey before squeezing the syringe and expelling the semen into the ovaduct. The device is portable so that it may be taken directly to the domestic birds and used by one man to impregnate a large number of birds in a short amount of time.
Using the present invention, a man simply cranks the filler, inserts the syringe, withdraws the syringe and straw, impregnates a bird, discards the straw and repeats the cycle. Turning a handle of one filler removes a straw from storage and aligns it with a nozzle while preloading a pump. Inserting the syringe triggers the pump, and withdrawing the syringe withdraws a loaded straw. Turning a handle on a second machine advances a straw from a hopper, inserts a nozzle in the straw while pushing a previously filled straw into a syringe, fills the straw and withdraws the nozzle. A person inserts the syringe, turns the handle and withdraws the syringe with a filled straw, impregnates a bird, discards the straw, reinserts the syringe and turns the handle to load the next straw in the syringe and to fill the following straw.
