Effect of split weaning on sow ovulatory responses to injection of gonadotrophins during lactation
Animal-related factors associated with piglet mortality in a bedded, group-farrowing system
PCV2: Possible transmission to sows through artificial insemination and effects on quality of boar semen
PCV2 can be shed into semen by infected boars and research suggests that the virus can then be transmitted to gilts and sows by AI causing reproductive failure but there is no evidence that PCV2 in semen has effects on various characteristics of sperm cells.

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.

The pig genome
Teams from 54 research groups, led by the Universities of Edinburgh (UK), Illinois (USA), Uppsala (Sweden) and Wageningen (Netherlands) have sequenced the entire genome of the pig.
TOPIGS finds SNPs for litter birthweight and litter uniformity
Nurse sows
As of the 3rd-4th day of lactation it is not recommendable anymore to replace small piglets and piglets with poor a growth rate for good piglets, because it is probable that the teat that has to be used has already dried off due to the scarce stimulation received for several consecutive days.
