Field Data Analysis of Boar Semen Quality [PDF]

Reproduction in Domestic Animals, 2011
ContentsThis contribution provides an overview of approaches to correlate sow fertility data with boar semen quality characteristics. Large data sets of fertility data and ejaculate data are more suitable to analyse effects of semen quality characteristics on field fertility. Variation in fertility in sows is large.

Association with Post-Thawed Semen Motility and Kinematic Characteristics of g.35756T>C on Estrogen Receptor 1 (ESR1) Gene in Duroc Pigs

Journal of Animal Reproduction and Biotechnology, 2015
Cryopreservation of boar semen is continually researched in reproductive technologies and genetic resource banking in breed conservation. For evaluating the boar semen quality, sperm motility (MOT) is an important parameter because the movement of ...

Spermadhesin PSP-I/PSP-II heterodimer induces migration of polymorphonuclear neutrophils into the uterine cavity of the sow [PDF]

, 2009
The heterogeneous seminal plasma (SP) is involved in endometrial inflammation and following immune changes that occur post-mating in pigs. This study tested whether SP spermadhesins (binding heparin [HBPs] or not [PSP I/PSP II]) recruit different ...

Role of oxidative stress and antioxidants in domestic and non-domestic cat spermatozoa [PDF]

, 2010
Living cells, including spermatozoa, stored under aerobic conditions require oxygen to support their normal metabolism. Excessive levels of metabolites (reactive oxygen species; ROS) can cause cell damage or lipid peroxidation.

Lipid Peroxidation in Semen of the Boar [PDF]

Acta Veterinaria Brno, 1979
Smutna M., o. Synek: Lipid Peroxidation in Semen of the Boar. Acta vet. Bmo, 48, 1979: 35-43. During the catalyzed aerobic incubation of the complete boar semen malonyl­ dialdehyde (MDA) is produced. MDA is a good indicator of peroxidative decom­ position of polyunsaturated fatty acids.
