Conservation decisions based on neutral genetic diversity have been observed to promote retention of useful quantitative variation in biological populations. An experiment was undertaken to determine the association between microsatellite marker polymorphisms and phenotypic variation in semen production and cryosurvival traits in bulls. Thirty-five ejaculates were collected from ten bulls of two breeds and evaluated before and after cryopreservation for several semen traits.

- The study investigated the differences in sperm cryosurvival between two breeds of Sanga cattle (Mashona and Tuli) and how using ethylene glycol (EG) instead of glycerol (GLY) might affect it.
- Tuli bulls had larger but lower quality ejaculates compared to Mashona bulls, with Mashona semen showing better motility and morphology.
- Results indicated that using EG instead of GLY did not improve sperm quality or cryosurvival significantly between breeds, implying that other mechanisms may influence sperm cryostress tolerance.
