  1. 1. Äggstockscystor hos mjölkkor : en jämförelse av den kliniska bilden, förekomst, och diagnostiken idag mot för 10–20 år sedan

    University essay from SLU/Dept. of Clinical Sciences

    Author : Julia Nygårds; [2024]
    Keywords : follikelcysta; fruktsamhetstörning; fertilitet; riskfaktorer;

    Abstract : Äggstockscystor är en vanlig anledning till nedsatt fruktsamhet hos mjölkkor. Tillståndet uppstår till följd av en utebliven ägglossning där follikeln fortsätter att växa och blir kvarstående i äggstocken. Cystorna gör korna infertila under tiden som de finns kvar i äggstocken och kan därmed förlänga kalvningsintervallet. READ MORE

  3. 2. Bacteria in the vagina during the estrous cycle in mares

    University essay from SLU/Dept. of Clinical Sciences

    Author : Timjan Åkerholm; [2023]
    Keywords : artificial insemination; bacteriology; breeding; embryo transfer; equine reproduction; estrous cycle; ovulation; stud farm; vagina;

    Abstract : An understanding of the normal bacterial flora of any organ is essential to provide the background to conditions and interventions that might cause the flora to change. In the vagina of the mare, a change of bacterial flora could be induced by introduction of semen, treatment with antibiotics, backflow from an unhealthy uterus etc. READ MORE

  4. 3. 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.

  5. 4. 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

  6. 5. Development of a method for preparing alpaca semen by colloid centrifugation

    University essay from SLU/Dept. of Clinical Sciences

    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
