  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.

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

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

    Abstract : 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. READ MORE
