The chamois of Abruzzi (Rupicapra pyrenaica ornata) has been classified as endangered by the WorldUnion for Conservation.The objective of this study was to analyze seasonal differences in the characteristics of various malereproductive organs and in semen quality. The study was conduced during 2004 in the reserve of Lama deiPeligni (Italy) on three chamois males aged between 2 and 5 years. Males were captured during March–Maymonths and October–December months. Various testicular and scrotal measurements were taken and semenwas collected using an electroejaculator. Sperm motility patternwas evaluated using computer assisted spermanalyzer, membrane integrity using differential staining and morphology with phase contrast microscopy.Testicular size, sperm motility membrane integrity and the percent of morphological normal spermatozoawere greater during October–December.The authors concluded that sperm characteristics are strongly influenced by season and that semen collectedin this period (breeding season) has suitable quality for manipulation and long-term preservation.[...]

Abstract
The chamois of Abruzzi (Rupicapra pyrenaica ornata) has been classified as endangered by the WorldUnion for Conservation.The objective of this study was to analyze seasonal differences in the characteristics of various malereproductive organs and in semen quality. The study was conduced during 2004 in the reserve of Lama deiPeligni (Italy) on three chamois males aged between 2 and 5 years. Males were captured during March–Maymonths and October–December months. Various testicular and scrotal measurements were taken and semenwas collected using an electroejaculator. Sperm motility patternwas evaluated using computer assisted spermanalyzer, membrane integrity using differential staining and morphology with phase contrast microscopy.Testicular size, sperm motility membrane integrity and the percent of morphological normal spermatozoawere greater during October–December.The authors concluded that sperm characteristics are strongly influenced by season and that semen collectedin this period (breeding season) has suitable quality for manipulation and long-term preservation.[...]I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
