“…This is in agreement with the observations of Odehnalova et al (2008) who reported that the lowest number of stillborn piglets were seen in deliveries at optimal room temperature (16-22ºC). Machado-Neto et al (1987) demonstrated that elevated temperature around farrowing exerted stress on the sow, resulting in a higher cortisol concentration in the blood serum.…”

Mummification is often noticed in pigs compared to other species due to large litter size. The agents responsible for the reproductive failure in sows may lead to a wide range of sequelae, including abortions, stillbirth, mummification, embryonic death. High prolificacy is associated with increased incidence of stillbirths and mummified fetuses. Plethoras of other foetal and maternal factors have been associated with incidence of still birth and mummification. Identification of those risk factors have been associated with stillbirth and mummified fetuses can helps in optimal herd reproductive efficiency.

“…However, data on the impact of managemental related factors on stillborn piglets are scarce and mainly focused on supervision of farrowing (Holyoake et al, 1995;Le Cozler et al, 2002;Lucia et al, 2002), pen design (Fraser et al, 1997), ambient temperature (Odehnalova et al, 2008) or dietary fibre (Guillemet et al, 2007).…”

“…Numerous predisposing factors are incriminated in this situation; some are directly related to sows while others are attributed to the piglets themselves (van Dijk et al 2005(van Dijk et al , 2006Alonso-Spilsbury et al 2007). The most important maternal factors involved in neonatal viability are number of parturitions, mothering skills, diameter of the pelvic canal, abnormal hormonal regulation and uterine physiology, prolonged expulsion periods secondary uterine inertia (uterine atony), maternal hypoxia resulting from temperatures above 35 °C in the delivery room, among many others (Alonso-Spilsbury et al 2005, 2007Odehnalova et al 2008;Olmos-Hernandez et al 2008).…”

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 transitional period during expulsion from the uterus to the birth of a newborn is of utmost importance since many adaptation problems may be detected, such as thermoregulation alterations and breathing difficulties (Odehnalová et al, 2008). The understanding of normal transitional physiological changes of the newborn piglets is important for evaluating their vitality (Sanchez et al, 2009;Maniau et al, 2010).…”

Clinical studies by Mota-Rojas et al. (2007) carried out on commercial pig farms showed that out of 1000 newly born piglets between 150 and 200 animals experienced apnoea after birth and it was related to perinatal asphyxia longer than 30 s, affecting the vitality in a negative way and delaying the latency of connecting to the dam's teat, which represents an economic impact for the producer. In another study where 11 324 farrowings were analysed from 5000 breeding Mexican pig farms, MotaRojas and Ramírez (1996) ABSTRACT:The objective of this study was to compare the metabolic and electrolytic profile as well as the morphological appearance of the umbilical cord and newly born piglets' weight that failed the vitality test scale compared to those who passed. Newborn piglets were divided into three groups according to the vitality with a modified Apgar score at birth: Group 1, failing with a score < 5 (G 1 : n = 218), Group 2 had a score of 6 to 7 (G 2 : n = 439) and Group 3 had scores > 8 (G 3 : n = 464). Results showed significant differences among groups (P < 0.05) in the physio-metabolic pH, PCO 2 , PO 2 , Na + , Ca 2+ , glucose, lactate and bicarbonate values. Regarding weight, temperature and latency to connect the maternal teat, there were also significant differences (P < 0.05) among groups; it took 23.38 min for G 3 while neonatal piglets from G 1 took 30 min longer (P < 0.05) to make the first teat contact. The neonates from the latter group had a higher percentage (75.68%) of broken umbilical cords, with higher birth weight (+200 g, P < 0.05), showed higher than normal blood glucose concentrations, and had lower body temperature at birth (-0.7°C, P < 0.05) and PO 2 in comparison with the other groups of neonates that passed the vitality score. A novel point of this study is the profile characterization of piglets that failed and passed the vitality score; we expect that the data provided may be applicable as reference values of metabolic and electrolyte blood profiles in newborn piglets according to their vitality. In conclusion, this study demonstrates that low vitality newborn piglets had clearly undergone through perinatal asphyxia. Potential indicators increasing this condition are: high birth weight, low body temperature, vitality score ≤ 5, and the presence of the broken umbilical cord at birth.
