title: [Fluctuations of urea, cholesterol and triglyceride concentrations in plasma of clinically health piglets during the first four weeks of life].
abstract: The present study was designed to investigate fluctuations of plasma concentrations in urea, cholesterol and triglyceride in healthy piglets (Landrace x Pietrain) during the first four weeks of life. Blood samples were taken by venipuncture in 240 piglets thirty minutes after birth, after 6, 24, 48, 168, 336, 504 and 672 hours. Cholesterol and triglyceride concentrations exhibited minimum values after delivery and rose up to the 48th hour of life, what can be explained by colostrum intake. Although an increase of urea after birth was determined, but some of the following measured concentrations were under the initial value. The three parameters showed a significant dependency on the age (p < 0.001). After 6 hours there was a correlation of cholesterol concentration and sex (p = 0.001) and triglyceride concentrations have been correlated to body temperature after 24 and 48 hours (p = 0.009; p = 0.004). Before colostrum intake urea concentration has been associated to body temperature (0.001). The physiological significance of the observed fluctuations for adaptation from an intrauterine to an extrauterine life is discussed.
