NewsEvolution of the numerical productivity during the last decades
France has been, continuously, the country with the highest productivity in comparison with Spain and The Netherlands, reaching 28.70 weaned piglets per sow and year in 2013.

The effect of pre- and post-mating dietary restriction on embryonic survival in gilts
Reducing post-mating feed intakes to maintenance levels impaired embryo survival.
Colombia resumes the importation of live pigs from US and Canada
There were trade restrictions due to the presence of Porcine Epidemic Diarrhoea (PED) in both countries.
Effects of lactation length and boar contact in early lactation on expression of oestrus in multiparous sows
Boar contact is an effective method to stimulate oestrus within 26 days of farrowing in both lactating and weaned sows.
Different flavoured creep on piglet performance
Dietary novelty may be a method to stimulate early exploratory behaviour, feed intake and performance.
Use of paternity tests in swine
These tests have several practical applications, as the detection of boars that are linked to the appearance of hernias or the susceptibility towards certain enteric diseases or even syndromes like the PFTS.
Effectiveness of different farrowing induction protocols in sows using alphaprostol on day 114 of gestation
The aim of this study was to investigate the effects of different induction protocols when applied on d114 of gestation.
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.
