Iron supplementation at an appropriate dose in gestating sows can improve placental development and increase piglet survival.

Ear and tail damage are heritable traits and are moderately positively correlated.

Blood transcriptomic data substantially improved prediction performance for traits biologically related to the sampled tissue.

Characterization of plasma profiles among post fourth parity dams with differing lifetime born-alive and weaned production traits suggested unique features that may be related to various physiological systems, including immunological, metabolic, and hormonal.

Different backfat layers were regulated by distinct genetic variations.

Results suggest that Iberian pigs are furnished with increased metabolic flexibility to face short-term stress.

These results instill optimism for the prospect of implementing gene therapies in utero to prevent or correct many human genetic diseases, specifically multisystem disorders such as mitochondrial diseases.

The study provides insight into the patterns of human-mediated movement of feral swine across the US and from Canada to the northern areas of the US.

The method will substantially facilitate the development of therapeutics or subunit and live-attenuated vaccines for ASF.

The downregulation of muscular candidate genes in the inguinal tissue clarifies the genetic mechanisms involved with this anomaly in its primary site.

This case reports the level of ergot alkaloids and duration of exposure found under field conditions in a herd that experienced a high neonatal mortality event consequent to agalactia in the sows.

Certain advanced mass-spectrometry-based analytical tools have been found useful to characterise and authenticate a variety of meat products.

Boar semen storage at 5 °C is an innovative tool to reduce antibiotics in extenders.

The current study presents an algorithm that extracts novel, objective structural conformation traits and reports corresponding genetic and phenotypic parameters.

Piglets genetically less likely to present swine inflammation and necrosis syndrome signs are also more unlikely to suffer combined skin damage after weaning.

Stillbirths in young, hyper-prolific sows were linked to several factors including large litter sizes, prolonged cumulative birth intervals, and elevated body mass index.

Trial runs were conducted in winter and summer to compare five deep-litter bedding materials.

Breeding for resilience traits based on deviations in longitudinal weight data can decrease pigs’ tail biting wounds, lameness and mortality while improving uniformity at the pen level.

Combining vulva volume features with days from weaning could be a suitable method to detect the onset of oestrous in sows.

Photodynamic inactivation could be a promising contribution to the One Health concept with the potential to reduce antimicrobial resistance in animal husbandry.

Weaning a portion of the litter prior to mating in lactation improved pregnancy rates and embryo survival.

Thawing at 70 °C for 8 seconds maximizes post-thaw sperm quality, especially in those samples stored constantly submerged in liquid nitrogen.

With current low-protein diets, the T allele is expected to be cost-effective only in niche markets where a very high level of marbling is critical.
