|Abstract||Over the last decades, pigs have been genetically selected to produce larger litters. Large litters are related to decreased piglet birth weights (Quiniou et al., 2002, Livest. Prod. Sci. 78)and increased within-litter variation in piglet birth weight (Quesnel et al., 2008, Animal 2:12)leading to a higher piglet mortality (Milligan et al., 2002, Prev. Vet. Med. 56:2).
The aim of this study was to identify possible causes of within-litter variation in piglet birth weight by studying follicular development of sows afterweaningin relation to their estimated breeding value (EBV) for within-litter variation in piglet birth weight.
