Establishing the hypoosmotic swelling test for sperm analysis in collared peccaries ( Pecari tajacu )

摘要

It is necessary to be aware of the reproductive aspects of the collared peccaries (Pecari tajacu) when aiming for its multiplication under captivity. Until this moment, semen analysis in such species has been mainly based on the evaluation of classic parameters (Costa and Paula 2005; Souza et al., 2009). The hypoosmotic swelling (HOS) test was only empirically applied using distilled water as a hypoosmotic solution (Souza et al., 2009; Castelo et al., 2010).
