Trouble-shooting herd fertility problems
Let us assume that the expected farrowing rate and live-born litter sizes are 90% and 12.5, respectively, but that current performance is 82% and 11.3, respectively. This means that too many sows are bred but failing to farrow and those that farrow are having fewer pigs.
Body reserve mobilization during lactation in first parity sows and its effect on second litter size
The aim of this study was to evaluate the influence of sow body reserves at weaning and body reserve losses during the first lactation on the second litter size (SLS). A number of 1222 females which reached the second parity without failures such as return to estrus after insemination, abortion or failure to farrow, were analyzed. Measurements of body weight (BW), backfat thickness (BT) and body condition score (BCS) were taken within 24 h after farrowing and on the weaning day.
Russia - Temporary restrictions on import of breeding animals from a number of Danish farms
In 2010 the Rosselkhoznadzor authorized import of 1360 breeding pigs from Denmark to the Belgorodskaya Oblast. The animals were imported in three consignments accompanied with phytosanitary certificates issued by the National Veterinary Service of Denmark according to which the animals were clinically healthy. 320 animals with lesions on legs and limp were detected in the course of the daily clinical examination in the quarantine period.

United Kingdom - British pig production still lags behind
Despite improvements in daily liveweight gain and pigs finished per sow, Britain still lags behind its European competition in the production stakes.
The latest figures from the BPEX publication on international cost of production show Britain produced 1643kg pig meat per sow in 2009 – the lowest of all the EU countries.
Relationships between backfat thickness and reproductive efficiency of sows: A two-year trial involving two commercial herds fixing backfat thickness at breeding
In this study, we established whether controlling backfat thickness at breeding over a long time period can result in optimized reproductive performance in sows.

Placid sow answer to European stall ban at EuroTier
By using genes from the Chinese Meishan, over the past 12 years ACMC has developed an F1 hybrid, the AC1, that has an exceptionally placid temperament and is well suited to group systems, without compromising feed conversion, growth rate or lean meat percentage.
Effect of storage for 24 h at 18°C on sperm quality and a comparison of two assays for sperm membrane lipid peroxidation
Boars having normal (71.1 ± 1.2%; n = 10) or low (35.12 ± 3.9%; n = 10) sperm motility 24 h after collection were used, and semen was evaluated following storage in Beltsville Thawing Solution (BTS) for 24 h at 18°C. Sperm lipids were extracted and lipid peroxidation quantified.
United Kingdom signs deal to export breeding pigs to China
Business Secretary Vince Cable today signed an agreement worth many millions of pounds for the UK economy that will allow the export of British breeding pigs to China, home to half of the world’s pig population.
Agreement has also been reached on health certification to allow a start to be made on the export of UK pigmeat to China.
Effect of supplementing Saccharomyces cerevisiae fermentation product in sow diets on reproductive performance in a commercial environment
Sow and litter performance may be improved by dietary yeast cell supplementation.
The present and future of cryogenically preserved of swine semen
Despite its scarce use in commercial artificial insemination programs (used only in 1% of all inseminated sows) nowadays no one questions the sanitary, economic, and productive advantages of cryogenically preserved semen with respect to fresh or refrigerated semen.
