Abstract

Selenium (hereafter, Se) concentrations were measured in the whole blood of brood sows taken at each stage of pregnancy and the whole blood of piglets at each stage of growth, as well as Se levels in the sow's milk. Results showed the whole blood Se level of pregnant sows decreased in middle to late pregnancy (89 ng/L in week 8 and 96 ng/L in week 16) compared to the 186 ng/L in early pregnancy (3 weeks), but recovered to 207 ng/L after parturition (at 18 weeks). Meanwhile, Se levels in piglet whole blood were 225 ng/L for 4-months old piglets and 223 ng/L for 6-months old piglets, showing consistent high levels in the later stages of growth, while the Se contents of piglet blood were low at birth and at weaning, 149 ng/L and 141 ng/L, respectively. Also, high Se content was observed in the sow's milk from at birth (248 ng/L) to 2 days after birth (175 ng/L), but decreased to 89 ng/L at weaning (21 days after birth). Further, the correlation was recognized between the Se contents in whole blood of sows one week before parturition and those in colostrum. These results suggest the need for a prompt supplementation of Se, toward middle pregnancy to improve and maintain the blood Se levels in sow and piglet.
