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.

Sow mortality: How and who? (1/2)
To reduce mortality, it is essential to diagnose the causes. To do so, we must answer four basic questions: how, who, when, and where? In this article, we'll address the first two.
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.
Tip: Book to record weekly matings
In this logbook, each page corresponds to a week of the year in which all the matings during the week are recorded.
Cross fostering and nurse sows (II): How to do the movements?
We focus on moving surplus piglets, which forces us to use nurse sows. We explain two ways to do this in a very visual video.
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.
Non-productive days or inefficient days?
We propose a more direct indicator to look at and analyze reproductive problems on the farm.
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.
Topigs Norsvin dam lines. Genetic criteria
What are the selection objectives of the Topigs Norsvin dam lines? Jonatan Sánchez-Osorio, Technical Director of Topigs Norsvin Spain, explains them to us in this article.
Tip to facilitate hand feeding of farrowing sows
A small cart is parked at the end of the aisle of each farrowing room, just below a dry feed distribution line.
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.
