1. 1. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

   University essay from SLU/Dept. of Clinical Sciences

   Author : Lea Enenkelová; [2021]
   Keywords : sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

   Abstract : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.

3. 2. Effect of seminal plasma on the acrosome status of cryopreserved stallion spermatozoa

   University essay from SLU/Dept. of Clinical Sciences

   Author : Michaela Toni; [2021]
   Keywords : acrosome; cryopreservation; artificial insemination; seminal plasma; spermatozoa; equine; stallion; “good freezer”; “bad freezer”; acrosome status; capacitation;

   Abstract : Today breeding through artificial insemination (AI) with cryopreserved semen is frequently used in several domestic species, but its use is more problematic in horses, partly because of reduced sperm quality and partly because the timing of insemination relative to ovulation is more crucial for frozen semen than for fresh. Therefore, improvements in the freezing technique are needed. READ MORE

4. 3. Development of a method for preparing alpaca semen by colloid centrifugation

   University essay from SLU/Dept. of Clinical Sciences

   Author : Sofia Karlsson Warring; [2019]
   Keywords : alpaca semen; single layer centrifugation; colloid; motility; artificial insemination.;

   Abstract : Alpacas belong to the South American Camelids and they share many characteristics with other camelids. The camelids have unique reproductive characteristics; one example of that is the high viscosity of their semen. READ MORE

5. 4. Can colloid centrifugation of fresh semen improve post-thaw quality of cryopreserved alpaca spermatozoa?

6. 5. Kvalitén hos SLC-selekterad hingstsperma : mitokondriella membranpotentialen och produktion av ROS

   University essay from SLU/Dept. of Clinical Sciences

   Author : Anne Lagerqvist; [2013]
   Keywords : Single layer centrifugation; Hingst; Sperma; Reaktiva syreföreningar; Mitokondriell membranpotential;

   Abstract : Studiens målsättning var att utvärdera kvalitén hos hingstsperma selekterad med hjälp av Single Layer Centrifugation (SLC), med huvudsyftet att studera den mitokondriella membranpotentialen (ΔΨm) och förekomsten av reaktiva syreföreningar (ROS) hos hingstspermier före och efter SLC. Ett insemineringsförsök med SLC selekterad och rutinspädd sperma genomfördes även på ett litet antal ston, men inga slutsatser kunde dras av resultaten. READ MORE
