Genomic analysis reveals selection for Asian genes in European pigs following human-mediated introgression
Researchers from Wageningen University explain that a number of important characteristics of European pigs have Asian origins.

Risk factors for lameness development in sows within the first days of group-housing
The aim of the present study was to determine risk factors for lameness development within the first days of group-housing, with a focus on housing conditions, management and post-mixing aggression in sows.
Measures of the ovaries and uterus during development of gilts selected for differences in uterine capacity
Selection for increased UC results in larger ovaries and uterine horns, but TRU was not useful for estimating these traits in gilts of the age studied.
Compounds from multilayer plastic bags cause reproductive failures in artificial insemination
This is the first described relationship between reproductive failure and toxic compounds released from plastic bags.
The importance of hyperprolificacy
Achieving a high prolificacy and knowing how to take advantage of it (transform it into weaned piglets) is vital for the productivity of a sow farm.
The battle of the sexes starts in the oviduct: modulation of oviductal transcriptome by X and Y-bearing spermatozoa
Data suggest that the oviduct functions as a biological sensor that screens the spermatozoon, and then responds by modifying the oviductal environment.
Effect of cross-fostering and oral supplementation with colostrums on performance of newborn piglets
The aim of the experiment was to study the effect on litter performance of two oral supplementation strategies on piglets born weighing 1.35 kg or less.
Energy savings using cover-nests in farrowing rooms
The use of these nests help create two well-differentiated areas: a warmer one for the piglets and a cooler one for the sows.
Italy: a patent for the genetic identification of the Cinta Senese breed has been developed
The patented method has allowed the definition of the minimum genetic traits that allow to identify the Cinta Senese breed (genotype) and the genetic variability level within the breed.
Clinical case: Reproductive disorders in a newly established herd
The veterinarian is called from a new established herd in Brittany because some clinical signs appear on gilts from the two first deliveries introduced in the farm.
Swine artificial insemination: which technique to use and how many sperm per dose?
We should be cautious when setting the number of sperm per insemination dose, so the urge to reduce it does not make us use a number that is under the fertility threshold. Something that may be productive and/or profitable for a certain farm may not be so for another farm.
Supplementing cryopreservation media with reduced glutathione increases fertility of sows
Supplementing freezing media with 2 mm GSH greatly improves boar sperm cryopreservation technology, as it significantly improves the fertilizing ability of frozen-thawed spermatozoa.
Sino-French agreement in the agriculture and agri-food sectors
This agreement will strengthen the pig meat, fowl and wine exports.
Comparison of management options for sows kept in pens with electronic feeding stations
These results demonstrate that management options can affect the reproductive performance and injuries of gestating sows in the ESF system.
Sow overmanagement consequences (2/2)
The results reveal that the stress that the sows due to excessive interventions around the moment of the farrowing causes a clear increase in the pre-weaning mortality.
Sow overmanagement consequences (1/2)
We saw aggressiveness in the sows, and we suspected that it could have been caused by the handling around the moment of the farrowing. We decided to register and analyze the data relative to the handling in order to confirm our suspicions.
