Fertility Test of Frozen Boar Semen [PDF]

Australian Journal of Biological Sciences, 1976
The fertility results of two experiments are presented. In experiment 1, the semen was frozen in tris-fructose-EDTA or BF3 diluents at 0'25xl09/mI sperm concentration and extended after thawing with either seminal plasma (SP) or the freezing medium (FM) containing no cryoprotective agent.

Fertility after photodynamic inactivation of bacteria in extended boar semen. [PDF]

Front Microbiol
Antimicrobial resistance is an increasing challenge in semen preservation of breeding animals, especially in the porcine species. Bacteria are a natural component of semen, and their growth should be inhibited to protect sperm fertilizing capacity and ...

A High Incidence of Sperm with Cytoplasmic Droplets Affects the Response to Bicarbonate in Preserved Boar Semen

Animals, 2021
Retained cytoplasmic droplets (CD) are the most frequent sperm abnormality in boar semen. A high incidence of CD is associated with subfertility, but the underlaying reasons are not well understood. The storage of extended semen might augment the adverse

Fertility of Frozen-Thawed Boar Semen [PDF]

Australian Journal of Biological Sciences, 1979
Farrowing results of six fertility tests are presented. Semen was processed by removal of seminal plasma and addition of glycerol at 30°C before (method A) or after (method B) stepwise cooling to 5°C, and by the Beltsville method (C). Sperm concentrations at freezing were 0·9 x 109/ml (A and B) and 0·6x 109/ml (C).

Reduced glutathione and cysteine hydrochloride on crossbred bull semen

, 2012
Over the last few years, good quality freezable semen was not utilized effectively due to less knowledge about the freezability of semen. One reason is the lack of sufficient antioxidants in the seminal plasma and semen extender.

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 ...

Effects of supplemental betaine to semen extenders on semen quality in boars [PDF]

Translational Animal Science, 2018
AbstractTwo experiments were conducted to evaluate the use of supplemental betaine in commercially available semen extenders. In experiment 1 (Exp1), semen was collected from six mature boars once weekly for 6 wk (3 wk in summer and 3 wk in winter) and diluted into a commercial extender with the following betaine concentrations: 0, 51, 102, and 205 mM.
