Abstract: The invention provides a method for vaccinating one or more avians in need thereof. The vaccination method comprises administering to the one or more avians a stable foam in an amount effective for inducing a neutralizing immune response against an infectious pathogen in the one or more avians. The foam comprises a gas and a liquid, and the liquid comprises a vaccine and a foaming agent. The avian may be a chick. Also provided is a method for preparing the stable foam.

Abstract: An electrical connector includes a window assembly including an electrically insulating transparent base and a plurality of electrically insulating transparent windows extending outwardly therefrom. The connector may include an electrically conducting body having spaced apart cable-receiving passageways for receiving respective insulation-free electrical cable ends therein, and with each cable-receiving passageway having a cable inlet opening and a cable end viewing opening opposite the cable inlet opening. The body may also have at least one respective fastener-receiving passageway intersecting each cable-receiving passageway. The individual windows of the window assembly are aligned with respective cable end viewing openings to provide a cover and to permit visual confirmation of proper placement of the insulation-free electrical cable end within a corresponding one of the cable-receiving passageways.

Abstract: An electrical connector for a plurality of electrical cables may include an electrically conductive body having a plurality of spaced apart cable-receiving passageways for receiving respective electrical cable ends therein, and having at least one respective fastener-receiving passageway intersecting each cable-receiving passageway. The connector may also include an insulating cover on the electrically conductive body having a respective cable inlet aligned with each cable-receiving passageway. A respective cable end seal may be associated with each cable inlet. Each cable end seal may include an annular tear stop member including a series of concentric annular ribs, and a nipple coupled to an inner portion of the annular tear stop member so that the nipple is able to seal against smaller diameter electrical cable ends, and so that the annular tear stop member is able to be selectively torn and seal against larger diameter electrical cable ends.

The electrically conductive body may also have at least one respective fastener-receiving passageway intersecting each cable-receiving passageway, an insulating cover on the electrically conductive body, and respective cable and fastener inlets aligned with each cable-receiving and fastener-receiving passageway. A plurality of plug tether assemblies may each include a base engaged with an upper end portion of a respective cable inlet, and may have a first and second tether extending outwardly from the base. A cable inlet plug may be coupled to the first tether and be removably positioned in a respective cable inlet. A fastener inlet plug may be coupled to the second tether and removably positioned in a respective fastener inlet.
