[Influence of the number and birth weight of piglets to birth and parity on postnatal mortality of piglets].
Postnatal mortality rate of piglets increases in relation to the number of suckled piglets and decreases when piglet birth weight increases. Moreover it is lower with second parity sows independently of prolificacy. Higher mortality rate observed with first parity sows seems related to lower piglet birth weight.
