RESUMO
This study investigated the short-term storage of Honamli and Hair buck semen based on the relationships among the biochemical constituents of the seminal plasma. In total, 12 Honamli and Hair goat bucks (six of each breed) were used. Collected individual semen samples were divided into two parts, one placed in short-term storage and the other centrifuged to determine the biochemical constituents of the seminal plasma. Diluted semen samples were cooled to +4°C; the samples were stored at this temperature; the spermatological parameters (i.e., motility, plasma membrane and acrosome integrity [PMAI], viability and high mitochondrial membrane potential) were assessed at 0, 24, 48, 72 and 144 h. A significant positive correlation was determined between the PMAI, motility and viability with globulin, chlorine, alanine aminotransferase (AST) and aspartate aminotransferase (ALT). A positive correlation was detected between the PMAI and viability with total protein. In contrast, a negative correlation was determined between the motility and viability with sodium values in buck semen (p Ë .05). Also, it was evaluated the Hair buck samples became inviable across all parameters at 72 h, while the Honamli buck samples continued to be viable at 144 h. In conclusion, the seminal plasma biochemical parameters of total protein chlorine, globulin, albumin, sodium, AST and ALT correlated with spermatological parameters in buck semen. The factors of animal (p Ë .05) and time (p Ë .001) affected the spermatological parameters, but there was no interaction between the two factors (p > .05) during the short-term storage period. Also, it was determined that Honamli buck semen was more resistant to cold injury than Hair buck semen against cold injury during storage.
