  1. 1. AMH i serum och seminalplasma hos hund : association till spermakvalitet

    University essay from SLU/Dept. of Clinical Sciences

    Author : Hannah Olsson; [2021]
    Keywords : AMH; Anti-Müllerskt hormon; hund; berner sennen; spermakvalitet; spermiemotilitet; spermiemorfologi;

    Abstract : Anti-Müllerskt hormon (AMH) har föreslagits som en biomarkör för spermakvalitet, eftersom hormonet produceras av sertolicellen som stödjer spermiernas utveckling. Förändringar i produktion av AMH antas kunna visa på nedsatt funktion i sertolicellen, och på så sätt nedsatt funktion i spermieutvecklingen. READ MORE

  3. 2. The influence of antimicrobial agents on the development of antibiotic resistance in the vaginal bacterial flora of artificially inseminated mares : a study on mares in a stud environment

    University essay from SLU/Dept. of Clinical Sciences

    Author : Elin Wilén; [2021]
    Keywords : antibiotics; antimicrobial resistance; bacteriology; breeding; equine reproduction; reproductive techniques; semen extender; stud farm;

    Abstract : In Sweden and in many other countries, artificial insemination (AI) is frequently used in horse breeding. The technology makes it possible to use genetic material from horses in different geographical locations in an effective way, minimizing the risk of infection or even injury to both horses and stud personnel.

  4. 3. Testosterons betydelse för hanhundens fertilitet : kan analys av dess serumkoncentration bidra till fertilitetsdiagnostik?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Stina Wallander; [2021]
    Keywords : testosteron; SHBG; FAI; CPSE; spermier; fertilitet;

    Abstract : Vid avel av hundar är det viktigt med en god fruktsamhet för att få en bred avelsbas. För utvärdering av fertilitet hos handhudar används ofta analys av ejakulat. I denna studie analyseras även serumkoncentration av testosteron för att se om det är en koppling mellan den och spermakvaliteten eller en hanhunds fertilitet. READ MORE

  5. 4. The effect of the natural antioxidants catalase and epigallocatechin added after thawing on the quality of dromedary camel spermatozoa

    University essay from SLU/Dept. of Clinical Sciences

    Author : Johanna Grundin; [2018]
    Keywords : Camel semen; cryopreservation; antioxidants; reactive oxygen species; sperm quality analysis;

    Abstract : The objective of this study was to evaluate the effect of adding two natural antioxidants (Catalase and Epigallocatechin) to the thawing media on the quality of cryopreserved dromedary camel spermatozoa post-thaw. Also, an indirect measure of ROS production was performed by measuring malondialdehyde (MDA) production (a product of oxidative damage) post-thaw. READ MORE

  6. 5. Effect of freezing and thawing rates on camel sperm quality

    University essay from SLU/Dept. of Clinical Sciences

    Author : Bodil Elwing; [2017]
    Keywords : Camel semen; cryopreservation; freezing rate; thawing temperature; motility analysis;

    Abstract : The objective of this study was to evaluate the effect of different freezing rates and thawing temperatures on the quality of camel spermatozoa post thawing. Ten ejaculates from five male camels were frozen at five different freezing rates, achieved by placing the straws at specific heights above the surface of liquid nitrogen for different times (4 cm for 15 min; 1 cm for 15 min; 7 cm for 15 min; 7 cm for 5 min + 4 cm for 3 min; 4 cm for 5 min + 1 cm for 3 min) followed by storage in liquid nitrogen.
