Cryopreservation of South African indigenous goat semen
The aim of this study was to cryopreserve and evaluate frozen-thawed semen parameters. Electroejaculator was used to collect semen from six bucks. Semen samples were divided into two parts. In one part, seminal plasma was removed and was not in the other one. Both semen sample parts were extended with egg-yolk Tris extender. Semen was thereafter cryopreserved in straws using liquid nitrogen. Da...
متن کاملThe Effect of Cattle Seminal Plasma Crude Protein on the Cryopreservation of Goat Semen
This study aimed to improve the quality of cryopreserved goat semen for artificial insemination by the addition of cattle seminal plasma crude protein. Semen collected from cattle and centrifuged to obtain seminal plasma. Then it was purified to obtain the crude protein. The diluent used in this study was milk-yolk. There were three groups, control group without crude protein (P0), the addition...
متن کاملEffect of Egg Yolk and Removal of Seminal Fluid on Semen Cryopreservation in Norduz Goat
Cryopreservation of goat spermatozoa is a valuable tool for genetic management. Previous studies have shown the frezeeablity of spermatozoa from various goat breeds but also have difficulties with available protocols. Therefore, we want to investigate the effects of centrifugation and different egg yolk ratios (5% and 10%) on spermatological parameters of Norduz goat spermatozoa. A total number...
متن کاملEffect of sugars on characteristics of Boer goat semen after cryopreservation.
In order to improve Boer goat semen quality during cryopreservation process, the influence of sugar supplementation on semen characteristics of sperm were investigated. Three experiments were carried out to investigate the effect of (a) addition of two monosaccharides (fructose and glucose) and two disaccharides sugars (trehalose and sucrose) (b) sugar combination (fructose and trehalose, sucro...
