Goat semen cryopreservation with rainbow trout seminal plasma supplemented lecithin-based extenders.

The objective of this study was to determine the optimum concentrations of rainbow trout seminal plasma (RTS) supplemented extenders for goat semen quality at post-thaw and after incubation. Five sexually mature Saanen goat (Capra aegagrus hircus) were used for semen collection. Pooled semen was diluted with soybean lecithin-based extender without RTS (control) or supplemented with different concentrations of RTS (1%, 2%, 4% or 8%), at a final concentration of 150 × 10 spermatozoon/ml.

Successful cryopreservation of honey bee drone spermatozoa with royal jelly supplemented extenders.

The aim of the present study was to evaluate different concentrations of royal jelly (RJ) supplemented extenders for post-thawing quality of drone sperm. Semen samples were collected from sexually mature drones. Pooled semen was diluted with extender without RJ (control) or supplemented with different concentrations of RJ (1, 2, 4 or 8%).
