Gut microbiota affects the estrus return of sows by regulating the metabolism of sex steroid hormones
Changes in gut microbial composition significantly altered the functional capacity of steroid hormone biosynthesis in the gut microbiome.

Low-density lipoproteins, resveratrol and quercetin as alternative additives to improve boar semen cooling
Low-density lipoproteins can improve the motility and kinetics of boar semen during cooling while it could modulate the sperm's mitochondrial activity.
Factors associated with farrowing assistance in hyperprolific sows
The frequency of farrowing assistance in sows varied among herds and was influenced by parity number.
Genetic and phenotypic time trends of litter size, piglet mortality, and birth weight in pigs
The increases in litter size and piglet survival rates due to balanced breeding policies lead to reduced total numbers of dead piglets coinciding with a certain pig production volume.
Effect of postpartum meloxicam administration to sows and split-suckling
Postpartum administration of meloxicam to sows reduced clinical cases of disease, increased ADG in pigs, and increased carcass weight at slaughter.
Myo-inositol improves the viability of boar sperm during liquid storage
The addition of myo-inositol to semen extender improved the boar semen quality by decreasing the effects of oxidative stress during liquid preservation.
Heat stress alters the ovarian proteome in prepubertal gilts
Heat stress alters the ovarian proteome and multiple biological pathways and systems in prepubertal gilts; changes that potentially contribute to female infertility.
Negative dietary cation-anion difference and calcidiol supplementation in transition diets fed to sows and its impact on piglet survival, piglet weight, and sow metabolism
The modulation of dietary anion-cation difference may enhance sow performance.
Fertility responses of melatonin-treated gilts when there are different temperatures and lighting conditions
Melatonin treatment had positive effects on estrous duration and embryo survival, especially in the summer.
Vaginal and vestibular electrical resistance as an alternative marker for optimum timing of artificial insemination
Change in electrical resistance in the vagina has the potential to accurately predict ovulation timing, but more work is required.
Long-acting injectable progesterone treatment prior to puberty induction in gilts
Injectable progesterone treatment did not benefit the reproductive performance of prepubertal and peripubertal gilts.
Analysis of artificial insemination center management factors that contribute to sperm parameters and boar longevity
The results reveal better sperm quality for untreated boars than for PGF2α-treated boars, which might indicate that the underlying fertility of boars necessitating treatment is inferior compared to boars that can be collected without further treatment.
333 Emerging voices: Biochemical, neurochemical, morphological and proteomic study of different nutritional conditions in Iberian pigs
The consequences of different nutritional changes were analyzed, whether applied to the pregnant mother or directly to the offspring. Doctoral thesis from the Faculty of Veterinary Medicine, UAB, Spain. Advised by Anna Bassols and with the collaboration of Antonio Gonzalez de Bulnes.
Flavour supplementation to improve sow reproductive performance and microbiota during late gestation and lactation
Flavor supplementation improved the reproductive performance of the sows by changing the fecal microbial profile.
Differences of semen microbiota among breeding boars with different reproductive ages
The semen of older boars contained a higher abundance of harmful bacteria, which contributes to the observed reduction in semen anti-oxidant capacity and overall semen quality in this group.
The impact of bump feeding on sow reproductive performance, milk yield, piglet birth weight, and farrowing behavior
Increasing feed intake during late gestation may improve sow and litter performance.
