The glucose concentration in sows tends to undergo slight rise within 24 hours from farrowing, while the concentration of free fatty acids declines from the onset of lactation. Cortisol went up on the day of farrowing and dropped afterwards, but neither movement was secured. The plasma values of newborn piglets were compared to those of their dams Cortisol was higher (15.0 +/- 6.4 and 9.7 +/- 3.7 microgram/100 ml), but glucose concentrations were lower (50 +/- 9 and 78 +/- 9 mg/100 ml), while the average levels of free fatty acids were in good agreement. In the nursing period, cortisol dropped to one fifth of the original value within 24 hours from birth and stayed at that level. Glucose increased to a maximum within twelve hours and declined continuously along with progressing nursing period. The level of free fatty acids, too, rose significantly up to the fifth day after birth. Cortisol, glucose, and free fatty acids in store pigs, aged 28 days, were lower than in nursed piglets of the same age.
母猪的葡萄糖浓度在分娩后24小时内往往会略有上升，而游离脂肪酸浓度从泌乳开始就会下降。皮质醇在分娩当天上升，之后下降，但这两种变化都不稳定。将新生仔猪的血浆值与其母猪的血浆值进行比较，皮质醇较高（分别为15.0±6.4和9.7±3.7微克/100毫升），但葡萄糖浓度较低（分别为50±9和78±9毫克/100毫升），而游离脂肪酸的平均水平相当。在哺乳期，皮质醇在出生后24小时内降至初始值的五分之一并维持在该水平。葡萄糖在12小时内升至最高值，并随着哺乳期的推进持续下降。游离脂肪酸水平在出生后第五天也显著上升。28日龄的育肥猪体内的皮质醇、葡萄糖和游离脂肪酸水平低于同龄的哺乳仔猪。
