Factors affecting boar semen quality and fertility [PDF]

, 2008
Aim of the research – to assess the factors that influence boar sperm quality and their fertility results. Objectives: 1. To compare the Danish Landrace and Duroc boar sperm quality and sow fertility results; 2. To analyse the influence that boar age and

Effects of increased levels of supplemental vitamins during the summer in a commercial artificial insemination boar stud

Animal, 2019
Heat stress due to increasing extremes in ambient temperature and humidity results in reduced semen quality in boars. This has caused reduced efficiency of the swine industry, requiring more boars to breed the same number of sows.

Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

Semen characteristics of indigenous Lusitu boars compared to the Large White pig genotype reared in Zambia

Open Veterinary Journal
Background: Pigs contribute to the livelihoods of traditional pig farmers (TPFs) through meat production and economic gains. However, the production of pigs, particularly genotypes indigenous to Zambia, remains suboptimal, largely due to dominance of ...

Soil inoculation enhances early‐phase reintroduction success in two rare plant species

Restoration Ecology, EarlyView.
Abstract Introduction Reintroduction for conservation is an important measure to restore populations of vulnerable plant species. However, reintroduction success rates are relatively low. Inoculating reintroduced plants with facilitative microorganisms from native populations may enhance their performance.

Could Individual Variability in Resistance to Cryopreservation (“Freezability”) Serve as a Biomarker Reflecting Boar Fertility?

Animals
Subfertile boars often go undetected until they cause significant reproductive losses. Current semen quality assessments are limited in their ability to predict fertility, highlighting the need for complementary biomarkers.

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, Volume 14, Issue 7, Page 2166-2179, October 2026.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Evaluating Temperature Effects and Extension Cooling Rtaes on Boar Semen Quality

, 2009
Experiment one examined the effects of temperature variations between semen and extender on eleven different estimates of semen quality. Extender type, short or long term, and time interactions on the quality of semen were analyzed. Eight mature boars (n=

Advances in Boar Semen Cryopreservation [PDF]

, 2011
The present paper highlights aspects of the cryopreservation of boar semen, a species with particular large, fractionated ejaculates, and a cumbersome cryotechnology that had prevented its commercial application.
