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.
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.
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.
Effects of two mixing times post-service on the welfare of sows in a group housing system with free access stalls
Findings may explain numerically lower pregnancy and farrowing rates in sows mixed two days post-service.
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.
Effects of jute nesting material and enriched piglet mats on sow welfare and piglet survival
The jute material and piglet nests positively impacted sow welfare and piglet measures but did not translate into improved piglet survival.
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.
Impact of dietary supplementation of tributyrin on offspring immunity, gut microbiota, and diarrhoea rate in a sow model
Tributyrin supplementation in gestating and lactating diets may improve sow performance and litter intestinal health.
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.
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.
Detecting sow vulva size change around estrus using machine vision technology
The LiDAR camera has the potential as a non-invasive tool to help identify the sow's estrus.
Dam parity structure and body condition during lactation influence piglet growth and gilt sexual maturation through pre-finishing
Although progeny body weights were typically less from first parity dams through 45 days of age, these progeny were similar or heavier at 100 and 145 days of age in contrast to progeny from other parities.
