Quality control of semen processing in boar studs: A Brazilian scenario [PDF]
Artificial insemination success in swine is mainly associated with semen dose quality. Thus, this study compared quality control parameters in 11 Brazilian boar studs after applying audit services for 24 months (1,650 boars).

Detection and characterization of Lactobacillus spp. in the porcine seminal plasma and their influence on boar semen quality. [PDF]
The presence of pathogenic bacteria in ejaculates has been a topic in boar semen preservation over the last decades. Since little information is available on commensal bacteria in boar semen, the aim of the present study was to identify commensal ...

Management of boars for efficient semen production [PDF]
Consistent production of large quantities of fertile semen is a primary concern of boar management programmes. Common visual tests such as motility are poor indicators of the fertilizing capacity of an ejaculate. Research studies have demonstrated that, in general, if motility is 60% or greater, there are no relationships among the percentage of motile

Fertility of Frozen-Thawed Boar Semen [PDF]
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).

Fertility Test of Frozen Boar Semen [PDF]
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.

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

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

An Outbreak of Porcine Reproductive and Respiratory Syndrome Virus in Switzerland Following Import of Boar Semen [PDF]
An outbreak of porcine reproductive and respiratory syndrome virus (PRRSV) occurred in November 2012 in Switzerland (CH), traditionally PRRSV-free. It was detected after a German boar stud informed a semen importer about the detection of PRRSV during ...
