This study aimed to assess various parameters in newborn mules and found differences between mules and horses or donkeys in terms of body weight, time to stand and nurse, body temperature, and other laboratory parameters. These findings highlight the importance of comprehensive evaluation for newborn mules.
The study aimed to assess Apgar scores and collect data on clinical, hemato-biochemical, and venous blood gas parameters in seven mules during their first 48 hours of life. Apgar scores, heart rate (HR), respiratory rate (RR), body temperature (BT), body weight (BW), time to achieve sternal recumbency, stand, nurse, and pass meconium were recorded. Blood samples were collected at birth (T0), 6 (T6), 12 (T12), 24 (T24), 48 (T48) hours of life. Data distribution was verified and differences in laboratory parameters over time assessed. One foal had an Apgar score of 6/8, thus excluded from the statistical analysis. Three foals had an Apgar score of 7/8, three had a score of 8/8. All foals showed suckling reflex within 20 minutes and raised the head within 1 minute; six foals reached sternal recumbency within 2 minutes. Times to stand and nurse were 38.7 +/- 13.4 and 72.3 +/- 30.5 minutes, respectively. Five foals passed meconium spontaneously in 416.3 +/- 401.8 minutes. The mean HR, RR, and BT values were 92 +/- 16.1 bpm, 50.2 +/- 5.9 bpm, and 37.6 +/- 0.3 degrees C, respectively. Creatinine and lactate decreased from birth to 48 hours. Blood glucose increased from 12 hours. Mg increased from 12 to 24 hours. Compared to horses and donkeys, mules showed an intermediate BW, shorter time to stand and nurse, longer time to pass meconium, intermediate HR and lower RR. Compared to donkey mules showed lower BT. Other dissimilarities from the parental species were found in laboratory parameters. Our findings emphasize the need for reference ranges for a comprehensive evaluation of newborn mules.
