How to minimize the impact of small litters
The incidence and distribution of small litters and factors affecting the number of piglets born alive on swine farms.

What insemination method should I use?
We continue our series of articles in which swine reproduction and artificial insemination expert Javier Gil shares key points about proper management to improve fertility and prolificacy. This article addresses the criteria to establish correct insemination methods.
Vulva width could serve as useful gilt selection criteria
Reproductive tract scoring methods as a tool for identify gilts with improved productivity as breeding herd females.
Altrenogest supplementation during early pregnancy improves swine embryonic development
There is a lack of information about progesterone supplementation during early pregnancy regarding swine embryonic development. The objective was to evaluate the effects of progesterone/progestin supplementation from Day 6 of pregnancy on swine reproductive parameters.
The role of your farm on the sows' reproductive potential (2/2)
What is more important: the farm or genetics?

Is it worth to purchase hyperprolific sows for my farm?
Effects of L-proline during early-pregnancy and the sow parity on the birth-weight of piglets
L-proline supplementation during early-pregnancy improves litter size and birth weight in sows with negative energy balance.
Are all non-viable piglets, really not viable?
There are casualties in the farrowing unit due to poor colostrum intake but, how many are there really? Are they just being classified as non-viable piglets?
Genome-wide association study for sow lifetime productivity related traits in a Landrace purebred population
A genome-wide association study was performed to identify quantitative trait loci for SLP-related traits. A total of five genome-wide suggestive significant single nucleotide polymorphisms were identified.
Arginine and amino acids supplementation in gestating gilts
Arginine and other amino supplementation in gestating gilts improve farrowing and litter performance in low prolificity sows (≤14 total piglets born).
How to control piglets during split nursing
The disadvantage of some boxes is that some piglets are too big and lively and jump off easily.
Clinical case: Diffuse reproductive problems in high health conditions
The owner contacted us because he has seen a reduction in performance in recent months, although no decline has been identified in any particular parameter. He says that, overall, “the sows are doing worse".
How efficient are the current hyper-prolific lactating sows? (1/2)
The study described here was designed to determine if the body tissue mobilization during lactation imposed by feed restriction could affect litter size and sow performance in the subsequent lactation.
The ideal farrowing facilities: number of crates, room size, type of crates... (1/2)
Joan Wennberg discusses the ideal farrowing facilities with Heraclio Corchón and Javier Lorente. They do not always agree, which makes reading this document even more interesting.
Factors for improving reproductive performance of sows and herd productivity in commercial breeding herds
We review critical factors associated with reproductive performance of female breeding pigs, their lifetime performance and herd productivity in commercial herds. The factors include both sow-level and herd-level factors.
