n-3 fatty acid supplementation in sows
Feeding n-3 fatty acids to gilts may improve litter growth, but does not affect subsequent reproductive performance.

Piglet birth weight and litter uniformity: Effects of weaning-to-pregnancy interval and body condition changes in sows of different parities and crossbred lines
Litter uniformity is compromised by severe sow body condition loss during lactation and improved in sows with a prolonged WPI. These effects are likely related with (insufficient) restoration of follicle development.
Alpha-lipoic acid on antioxidative ability and performance of sows and nursing piglets
Dietary alpha-lipoic acid supplementation in sows enhances the antioxidant activity and performance of mothers and their offspring.
The use of crystalline amino acids in lactating sow diets
Corn/soybean meal lactation diets can contain up to 0.40% L–lysine-HCl with no detrimental effect on reproductive performance.
Sow losses/cullings: a Tower of Babel (I)
The registration of the sow losses/cullings in the management computer programs is normally something easy, but it is not always given the importance that it really has so, sometimes, the registration is incomplete, with wrong dates and without writing down the cause of the loss/culling. Nevertheless, its correct registration and its later analysis can give us very useful information for the correct technical-financial management of the farm.
United States: pork producers reaffirm industry support for producer choice on sow housing
At the National Pork Industry Forum, pork producers approved a resolution reaffirming the industry's position that producers should be able to select a sow housing system.
Animal-related factors associated with piglet mortality in a bedded, group-farrowing system
Farrowing behavior, cross-fostering, birth weight and gender of piglets were investigated.
Impact of feeding on the incidence of lameness in the sows and their longevity
The sow must be able to store enough calcium during the pregnancy to face the possible mobilizations during the lactation.
Effect of distributing primary and secondary antioxidants to the sow during the weaning‐estrus interval
The supply of the antioxidants to the sow during the weaning‐estrus interval significantly reduced both the percentage of immature piglets per litter and the within‐litter variation of birth weights.
United Kingdom: wean more pigs to be more profitable
The aim is to help every producer move towards an extra three pigs per sow per year weaned.
Lysine to metabolizable energy ratio affects growth performance, blood metabolites and hormones of lactating sows
Providing 3.05 g/Mcal ratio of SID Lys:ME in lactating sows, litter weight gain could be maximized.
Commission increases pressure on Member States to enforce group housing of sows
European Commission called on Belgium, Cyprus, Denmark, France, Germany, Greece, Ireland, Poland and Portugal to take action to address deficiencies in the implementation of EU legislation concerning the welfare of animals.
New section: Replacement rate simulator
We have developed a new simulator that will help us to calculate the number of gilts to be entered in a farm when its activity starts, when increasing its sow census or when calculating the replacement rate of an already working farm.
Effect of meal frequency on performance and behaviour of group‐housed gestating sows
Sows had received their daily ration in one or two meals. Reproductive performance during gestation and the following lactation was measured.
Effects of an increased feeding level during second gestation in sows
Increasing the feeding level during gestation improves weight gain of the sow and diminishes blood’s NEFA concentration, but does not affect the embryo or the placenta.
Marking the place where the Renco device must be placed
The goal is to increase the agility of the reading process of the body condition of the sows using the Renco device.
