The dependence of the growth rate and meat content of young boars on semen parameters and conception rate
The objective of the research was to conduct semen parameter and conception rate analyses on the basis of growth rate and meat content.

China: Swine imports to increase in 2017
Swine imports to increase in 2017 due to demand for high-quality genetics.
UK pig semen to improve pork quality in India
This latest move forms part of a large-scale development of the Punjabi pig sector and experts say it could open the door to other British suppliers.
Effect of Pseudomonas aeruginosa on sperm capacitation and protein phosphorylation of boar spermatozoa
The present study provides novel data regarding the effects of bacterial contamination on boar sperm, suggesting that the presence of P aeruginosa affects the fertilizing ability of boar sperm by altering its ability to accomplish IVC.
Strategic value of boar studs in production systems
Production of a minimum number of doses to maintain profitability and the increase in post-cervical insemination leads to an increase of the doses produced per boar and, therefore, their share of responsibility in the production process.
Effect of natural betaine on estimates of semen quality in mature AI boars during summer heat stress
Betaine supplementation at 0.63% and 1.26% tended to increase sperm concentration in the ejaculates by 6% and 13%, respectively.
Semen extenders on frozen-thawed boar sperm characteristics and distribution after deep intrauterine insemination in sows
We compared the effects of extenders of frozen-thawed semen on post-thaw sperm characteristics and the distribution of frozen-thawed spermatozoa in the female genital tract after fixed-timed deep intrauterine insemination (DIUI) in sows.
Optimization of post-cervical insemination in pigs: critical points
This article lists the critical points that must be considered for a successful post-cervical insemination in sows.
Comparison of specimens for detection of PRRSv infection in boar studs
These results showed that the highest assurance of providing PRRSV-negative semen to sow farms should be based on rRT-PCR testing of serum collected at the time of semen collection.
Current state of post-cervical insemination in multiparous, primiparous and nulliparous sows
It is necessary to find alternatives to definitely implement this technique in primiparous sows and start its use in gilts.
Morphological study of boar sperm during their passage through the female genital tract
Almost all the sperm that colonize the uterotubal junction had a normal morphology, with part of the abnormal sperm having been discarded in the backflow and part selected/modified on their way to the oviduct.
Analysis of hygienic critical control points in boar semen production
The present study emphasizes the need for both training of the laboratory staff in monitoring HCCP in routine semen production and audits in such AI centers for the external control of hygiene parameters.
Porcine semen as a vector for transmission of viral pathogens
Prevention of viral semen contamination should be the primary focus because it is easier to prevent contamination than to eliminate viruses once present in semen.
Influences on semen traits used for selection of young AI boars
A minimum age is proposed for young boars to qualify for selection, or alternatively, age-related semen quality thresholds in young boars should be established.
The use of oxytocin in liquid semen doses to reduce seasonal fluctuations in the reproductive performance of sows
On the basis of the presented results, it should be noted that the use of oxytocin into insemination doses improves the farrowing rate and other parameters of the reproductive performance of sows.
The effect of numbers of frozen-thawed boar sperm and addition of prostaglandin F2α at insemination on fertility in pigs
These results indicate that AI using 2.0 × 109 FTS can result in acceptable pregnancy rates and litter sizes but with no measurable benefit for addition of prostaglandin.
