Abstract: A culture collection instrument for use in animal husbandry includes a tubular swab holder adapted to receive an elongated rod having a swab element on its end and a tubular swab protector adapted to receive and hold the tubular swab holder. The tubular swab protector includes a scored portion thereon a predetermined distance from the end of the swab protector such that flexing of the swab protector predeterminely breaks the swab protector and swab element from the elongated rod to provide a sealed tubular holder for the cultured swab element.

Abstract: A shield protector device for use with artificial insemination instruments and/or culture collection devices, consisting of an inner tubular portion movable relative to an outer tubular sheath protector portion, includes a cylindrical housing having a closed end, which is sealingly attached to the distal end of the outer tubular sheath protector portion. The closed end of the housing is scored to provide a break-away membrane when the closed end of the shield protector is engaged by the inner tubular portion to complete the insemination or culture collection process.

Abstract: A mechanism for feeding fluid into capsules in a capsule-filling machine embodying a cam-controlled roller movable into and out of squeezing relation to a flexible feed tube, and movable along the tube in a fluid-ejecting direction when disposed in such squeezing relation to the tube, with tube shut off means and ejector nozzle positioning means operable in timed relation to the actuation of the roller.
