  1. 1. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Anna Kotila-Ioannou; [2022]
    Nyckelord :Camel Semen; Dromedary camel; Sperm-Hyaluronan Binding Assay; sperm quality analysis;

    Sammanfattning : The objective of this study was to assess the potential of Hyaluronan Binding Assay (HBA) to predict freezability and fertilization capacity of dromedary camel spermatozoa, and to determine if conventional sperm quality parameters and precursor of A-Kinase Anchoring Protein 4 (proAKAP4) values correlate with HBA results. Two semen samples were collected from each of six male camels. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

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

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

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

    Sammanfattning : 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. LÄS MER

  5. 4. Effect of different thawing protocols and addition of the antioxidants carnitine, catalase or glutathione prior to freezing on the post-thaw quality of cryopreserved camel spermatozoa

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

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

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

    Sammanfattning : 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.
