“…The percentage of still born varies from 5 to 15% and of them 10% die shortly before farrowing, 75% during farrowing and 15% immediately after farrowing ( (Glastonbury, 1977;Leenhouwers et al, 1999;Van der Lende, 2000;Koketsu et al, 2010). Pre-partum deaths are usually associated with infectious agents whereas intra-partum deaths are related to non-infectious etiological factors (Sprecher et al, 1974;Alonso-Spilsbury et al, 2004) The risk factors associated with stillbirth and mummified fetuses include litter size, infectious diseases, gestation length, parity number, farrowing length, farrowing interval, dystocia, high environmental temperature, body condition score and nutritional deficiencies (Dial et al, 1992;Zaleski and Hacker, 1993;Leenhouwers et al, 1999;Mengelinget al, 2000;Tantasuparuk et al, 2000;Lucia Jret al, 2002;Schneider et al, 2003). Identification of the risk factors has been associated with stillbirth and mummified fetuses.…”
