Abstract

A comparative study of 11 physiologic variables in 200 piglets and puppies during the first 7 days of life was done. Seven of 11 physiologic variables significantly changed in the 1st wk of the piglets' life. Five of 11 variables significantly changed in the first week of the puppies' life. Six of 11 variables were significantly different when the newborn piglet was compared to the newborn puppy. The rate and/or direction of 7 of 11 physiologic changes during the first day of life were significantly different when the piglet was compared to the puppy. It was concluded that there are marked physiologic differences between: the newborn piglets and the 7 day old piglet; the newborn puppy and the 7 day old puppy; the newborn piglet and the newborn puppy and the "maturation" rate of the piglet and the puppy.

摘要

对200只仔猪和幼犬出生后前7天的11项生理变量进行了一项对比研究。11项生理变量中有7项在仔猪出生后的第1周发生了显著变化。11项变量中有5项在幼犬出生后的第一周发生了显著变化。将新生仔猪与新生幼犬进行比较时，11项变量中有6项存在显著差异。将仔猪与幼犬进行比较时，11项生理变化中有7项在出生第一天的变化速率和/或方向存在显著差异。得出的结论是，新生仔猪与7日龄仔猪之间、新生幼犬与7日龄幼犬之间、新生仔猪与新生幼犬之间以及仔猪和幼犬的“成熟”速率之间存在明显的生理差异。
