  1. 1. Comet assay: Monitoring time-dependent DNA-fragmentation in two different types of cells, optimizing Flash-comet method for pig sperm analysis

    University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Author : Ewelina Rozwadowska; [2020]
    Keywords : Comet assay; Flash-comet; cell survival curves; TK6-cells; pig sperm;

    Abstract : DNA-damage, caused by different factors such as oxidative stress in cells, is common in living organisms. The damage includes DNA-fragmentation, such as single- and double strands breaks. READ MORE

  3. 2. Genetisk variation i spermakvalitet, och dess koppling till galtars fruktsamhet

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Torun Wallgren; [2011]
    Keywords : galt; fertilitet; spermiekvalitet; spermieegenskaper;

    Abstract : Det finns många faktorer som påverkar galtens ejakulatkvalitet, t.ex. genetisk bakgrund och miljöfaktorer. Om det finns ett samband mellan ejakulatets kvalitet och galtens verkliga fruktsamhet kan man lätt skilja på bra och dåliga galtar, och därmed sålla bort galtar med dålig fruktsamhet. READ MORE

  4. 3. Förekomst av leukocyter i råsperma hos semingaltar

    University essay from SLU/Dept. of Clinical Sciences

    Author : Maria Wahnström; [2008]
    Keywords : leukocyter; sperma; galt;

    Abstract : Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. READ MORE

  5. 4. The Sow Endosalpinx at different stages of the Oestrous cycle and at Anoestrus : studies on morphological changes and infiltration by cells of the immune system

    University essay from SLU/Dept. of Clinical Sciences

    Author : Jatesada Jiwakanon; [2004]
    Keywords : Sow; oviduct; endosalpinx; morphology; immune cell; immunohisto-chemistry;

    Abstract : The oviduct, together with its secretion, forms the environment in which gamete transport, sperm maturation, fertilization as well as early embryo transport and development occur. Morphological aspects, as well as immune cell distribution, have been described only to a limited extent regarding the pig oviduct. READ MORE

  6. 5. Deep freezing of concentrated boar semen for intra-uterine insemination

    University essay from SLU/Dept. of Clinical Sciences

    Author : Fernando Saravia Ramos; [2004]
    Keywords : spermatozoa; high sperm count artificial insemination AI doses; computer-assisted sperm analysis CASA ; flow cytometry; sHOST; boars;

    Abstract : Frozen-thawed (FT) boar semen for artificial insemination (AI) in commercial pig production is still only used in exceptional cases, mostly for incorporation of top genetics. Low sperm survival after a freezing procedure that is still considered suboptimal, which results in low farrowing rates and small litter sizes when conventional cervical AI is performed, are among the reasons why FT boar semen is rarely used in AI.
