ResumoIn order to investigate the correlation between the placenta weight and other piglet intra-delivery parameters, a study of 90 newly-parturient primiparous sows was carried out in a swine farm near Curitiba, Parana, Brazil. The animals were artificially inseminated with cooled semen produced in the farm. All the animals were readily assisted in the parturition as the obstetric aid was given for the placenta separation, placenta weighing, counting the piglet number and the classification of live, dead-born and mummified piglets. A total of 1,088 piglets and their placentas were studied. The gestation lasted on average 114 days. It was concluded that the weight of pig placenta did not show a correlation with the number of dead-born or the placenta expulsion time.
