“…Our results show that, similarly to the newborn infant [18], the metabolic rate is high just after birth in the neonatal pig but decreases during the first 3 h, the extent of the fall and the initial V 02 both being dependent on environmental temperature. Some observations can explain the initially high V 02.…”

Metabolic rates (VO₂) and respiratory quotients (RQ) have been measured in newborn pigs kept either in warm (31°C = WG) or in cold (18°C = CG) climatic conditions from birth to 24 h of age. The piglets were allowed to suckle every 80–85 min. At birth VO₂and RQ were high for both treatments. However, they became relatively constant after 30 min of life. They were higher for piglets kept in a cold environment (1.00 vs. 0.95 for RQ). After the first suckling VO₂ increased steadily over the first 24 h of life for WG and was kept constant (29.5 ml O₂/kg BW/min) for CG. RQ decreased from 0.90 to 0.80. For the first 24 h of life an increase of 55% of VO₂ was observed when the ambient temperature was decreased from 31 to 18°C. The fact that RQ was higher for CG than for WG (0.87 vs. 0.83) indicates that the newborn pig kept in cold conditions enhances its utilization of carbohydrates, in order to increase its heat production. Finally, our results show the positive relationship between colostrum intake and metabolic rate and emphasize the nutritional importance of colostrum during the first day of life.

“…In our studies we have maintained an ambient temperature of 30.5° to 30.9° C with a stable delivery room environment. A comparison of our results with those in the literature [3,5,10,13] is difficult because the results were obtained during various ages of the newborn and by different methods (Tab. II).…”

“…In the presence of an unchanging metabolic rate, the RT of newborns will fall more with a lower environmental temperature [7]. In the presence of equal environmental temperatures, the rectal temperatures of the healthy children differed from those of the resuscitated neonates.…”
