Semen collection, characterization, and cryopreservation in a Magellanic penguin (Spheniscus magellanicus)
Abstract 10.1002/(SICI)1098-2361(1999)18:33.3.CO;2-R A cooperative method was developed for collecting semen from a Magellanic penguin. Ejaculate parameters and semen production during a breeding season were characterized. Experiments were performed to study the effect on penguin spermatozoa of two temperatures (4°C and 21°C) for short-term storage, and two cryoprotectants (dimethylsulfoxide [DMSO] and ethylene glycol [EG]) for long-term […]
Cryogenic preservation of semen from the Aleutian Canada goose (Branta canadensis leucopareia)
Abstract 10.1002/zoo.1430090504.abs Aleutian Canada geese (Branta canadensis leucopareia) were inseminated with frozen-thawed semen containing 6% or 7% dimethylsulfoxide (DMSO) resulting in 32 fertile eggs and 17 goslings; with 7% DMSO, 19 of 31 eggs were fertile. Beltsville Poultry Semen Extender (BPSE), adjusted to 270 ± 30 mOs and 7.5 ± 0.4 pH, was used to […]
