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

    Master-uppsats, SLU/Dept. of Clinical Sciences

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

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

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

    Författare :Emma Norrestam; [2019]
    Nyckelord :alpaca semen; spermatozoa; cryopreservation; artificial insemination; single layer centrifugation;

  5. 4. Effekter av spädningsvätska på motilitet och fertilitet hos hingstsperma : en jämförelse av subjektiv motilitetsbedömning och QualispermTM

    L3-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Kaisa Ryytty; [2008]
    Nyckelord :hingst; sperma; Qualisperm; motilitet; fertilitet;

    Sammanfattning : At SLU, Divison of Reproduction, Dept of Clinical Science, there is an ongoing project on the development and evaluation of new methods for the assessment of stallion semen quality. This EEF-study, which is a part of that larger project, has focused on the effects on motility and fertility of stallion semen of two different extenders and selection. LÄS MER

  7. 5. Utvärdering av en ny selektionsmetod för hingstsperma : med avseende på membranintegriteten och membranstabiliteten

    L3-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

    Författare :Josefina Thorén; [2007]
    Nyckelord :reproduktion; spermie; häst; viabilitet; single layer; membranintegritet; membranstabilitet; kylförvaring;

    Sammanfattning : Today, equine breeding is based on performance and conformation, resulting in a vast variation in fertility among different horses, with noticeable economic losses as a consequence. The horse breeding industry is therefore in need of methods that diagnose the spermatozoa concerning their quality and provide the best sperm for AI. LÄS MER
