“…A severe degree of meconium staining of the skin has been associated with low or failing scores on the neonatal vitality scale and this occurs regularly when the umbilical cord has been ruptured (Mota-Rojas et al 2002, 2005aTrujillo-Ortega et al 2011). Meconium staining during farrowing correlates well with the rupture of umbilical cord in piglets born live from sows treated with oxytocin.…”

“…Meconium staining during farrowing correlates well with the rupture of umbilical cord in piglets born live from sows treated with oxytocin. In one study there was a positive relationship (r = 0.58) between the number of live born piglets with ruptured umbilical cords and the magnitude of meconium staining; thus it is suggested that the damage to the umbilical cord damage induced by oxytocin causes a sufficiently serious asphyxia that reflects in a higher degree of meconium staining in the neonatal skin (Mota-Rojas et al 2005a). Intrapartum asphyxia is also corroborated by the greater frequency of cyanosis and pale skin in piglets born to sows treated with oxytocin.…”

“…It should be noted nonetheless, that this point of view on the pathophysiology of neonatal hypoxaemia has been challenged by some researchers (Herpin et al 1996) who postulate that prolonged or intermittent asphyxia in utero or during the time of delivery does not necessarily lead to intrapartum stillbirths. In a recent study, Mota- Rojas et al (2005a) showed why birth accelerators administered to sows increase umbilical cord abnormalities at birth. These investigators reported a significant increase (P < 0.01) in the number of uterine contractions in farrowing sows treated with oxytocin at a dosage of 1 UI/kg of the live weight of the sow ( Figure 2A).…”

“…More recently, Mota-Rojas et al (2005a) studied the effect of oxytocin on umbilical cords and meconium staining in pigs born to sows treated with oxytocin. The results of this work proved a relationship between the degree of meconium staining in the skin and the number of piglets born with ruptured umbilical cords.…”

ABSTRACT:The objective of this review is to integrate clinical findings and laboratory analyses in such a way to improve the welfare of newborn piglets and achieve better prognoses of neonatal viability. Deaths during the intrapartum period account for a significant proportion of pre-weaning mortality in farms worldwide. Piglets which die during parturition generally have normal size and typically lack gross lesions at post-mortem examination. However, circulatory abnormalities in the umbilical cord help in assessing piglet viability. Cord lesions can be classified as normal (adhered), oedematous, congested or haemorrhagic and should always be evaluated in perinatal deaths. The likelihood of neonatal survival decreases rapidly as the severity of umbilical cord lesions increase. The physiometabolic blood profile which includes acid-base balance, degree of dehydration, mineral balance, metabolic expenditure and gas exchange are also useful clinical elements for properly assessing neonatal viability. Neonatal survival is notably reduced when the blood pH falls below 7.0, lactate rises above 90 mg/dl, bicarbonate drops below 10 mmol/l, or the pCO 2 increases above 110 mm/Hg. Blood calcium is also an excellent indicator of neonatal stress when used in combination with the other parameters mentioned above. Trembling due to an imbalance in the movement of calcium in muscle is also a factor involved in neonatal mortality. Neurological function in the newborn piglet could also be evaluated by adapting the Apgar score widely used in human perinatology. Neonates with scores lower than 6 in a 10 point scale have generally lower survival rates. The two most important indicators for this vitality score are breathing latency and bradycardia. If the neonate has apnoea for more than 5 min and the cardiac frequency does not increase to more than 110 beats per minute the prognosis for survival is rather poor.

“…The administration of prostaglandins combined with uterotonics like oxytocin and/or estradiol benzoate allow for increased accuracy in the prediction of the time of farrowing without a decrease in piglet survival rates or pig performance to weaning (Cassar et al, 2005;Mota-Rojas et al, 2005a). Nevertheless, the administration by a single intramuscular injection of prostaglandin F,, or its analogues provides the most effective result for inducing farrow (Kaeoket, 2006).…”
