Some hematological and cardiovascular parameters of the underweight neonatal piglets have been compared with normal-weight 1 and 7-day-old swine (Sus scrofa domestica). The underweight swine had a significantly lower leukocyte count, plasma protein level and blood glucose level, but a significantly higher plasma LDH level. Heart rate and arterial blood pressure were significantly lower in the underweight group. Based on the observed results it was postulated that the piglets born with a low body weight could also be physiologically immature since the cardiovascular parameters measured approximated those reported for normal fetuses of the same weight. Further studies are required to ascertain if a functional immaturity persists in the neonatal animals.
已将体重过轻的新生仔猪的一些血液学和心血管参数与正常体重的1日龄和7日龄猪（家猪）进行了比较。体重过轻的猪白细胞计数、血浆蛋白水平和血糖水平显著较低，但血浆乳酸脱氢酶水平显著较高。体重过轻组的心率和动脉血压显著较低。根据观察结果推测，出生时体重低的仔猪在生理上可能也不成熟，因为所测量的心血管参数与报道的相同体重正常胎儿的参数相近。需要进一步研究以确定新生动物是否持续存在功能不成熟的情况。
