The aim of this study was to evaluate the effect of semen collection method (artificial vagina compared to electroejaculation), season in which the semen was collected (breeding season compared to non-breeding season), freezing extender (Biladyl(®), Andromed(®) and skim milk based extender) and pre-treatment procedure (washing compared to non-washing) on post-thaw semen quality in buck. Ejacula...

The present study was conducted to observe the effect of increased osmolality of basic tris extender supplemented with trehalose and sucrose on post-thawing quality (motility, progressive motility, viability, the rate of acrosome abnormality, total abnormality and membrane integrity) of Markhoz goat spermatozoa. Fresh semen samples were evaluated for motility and sperm concentration. Only semen...

Abstract The aim of this study was to determine the effects gallic acid (GA) on frozen-thawed goat spermatozoa. Four Honamli bucks were used at their breeding season, and ejaculates collected by an electroejaculator. Mixed semen divided into following four groups: control (0 mM), low (L; 1 medium (M; 2 high (H; 4 mM) concentration GA. All groups frozen thawed in a water bath for spermatological...

A newly developed technique for trans-cervical deep uterine insemination of goats is described. An experiment was conducted to compare this transcervical method with the laparoscopic intrauterine insemination using frozen-thawed semen. Of the 46 primiparous and 21 multiparous estrus-synchronized Boer goat does inseminated transcervically, 71% (22/31) kidded compared with 53% (19/36) of does ins...

Abstract Korean black goat (Capra hircus coreanae) populations are dwindling and facing genetic erosion due to artificial insemination. Here, we introduced an estrus synchronization method for goats enable crossbreeding with non-native breeds on small farms investigated the application of insemination in goats. Semen was obtained using electro-ejaculation preserved a conventional simple freezin...

Infertility is a major problem affecting the reproductive performance of domestic animals. In the male goats, testicular degeneration appears to be a common cause of poor semen quality and infertility (Fraser, 1971; Mathai and Ramachandran, 1978; Refsal et al., 1983). Besides infectious causes, a number of non-infectious agents can cause testicular degeneration in male goats. These include exce...
