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.
333 Emerging voices - Individual and nutritional factors affecting the homogeneity and performance of Iberian pig production
An investigation at both phenotypic and genotypic levels of the implications of the intrauterine development of the piglets in the postnatal growth. Doctoral thesis from the Faculty of Veterinary Medicine, UCM, Spain, advised by Antonio Gonzalez de Bulnes, Cristina Óvilo Martín and Beatriz Isabel Redondo.
The impact of functional teat number on reproductive throughput in swine
Results suggest increasing functional teat number would enhance both piglet survival and reproductive throughput.
Genetic associations between human-directed behavior and intraspecific social aggression in growing pigs
Heritability estimates for all studied traits suggest they could be suitable as a method of phenotyping aggression and fear/boldness for genetic selection purposes.
Reproductive performance of gilts and weaned sows grouped at different days after insemination
Group housing gestating sows 2 days after breeding compromised litter size; however, mixing gilts on days 1 to 4 after breeding did not impair reproductive performance.
Lameness in pregnant sows alters placental stress response
Lameness may decrease sow gestation length and reduce placental efficiency in protecting the offspring from the sows’ stress response.
Genetic analysis of protein efficiency and its association with performance and meat quality traits under a protein-restricted diet
Protein efficiency is a heritable trait that can be considered in breeding programs to reduce the environmental impact of pig production.
Analysis of image-based sow activity patterns reveals associations with piglet survival and early growth
The live-born piglets of sows that were more active the day before farrowing, standing and in other activity than drinking and eating, had higher survival rates.
Update on the methods for semen quality evaluation in swine from farm to the lab
This work aims to summarise the methods utilised in farms and research laboratories to evaluate sperm quality in pigs.
Genetic parameters for early piglet weight, litter traits and number of functional teats in organic pigs
There is genetic variation in individual piglet weight, litter traits, and number of functional teats in organically and outdoor-reared pigs.
