To investigate effects of Ca level varying with feeding time daily in sows during late pregnancy on placental lipid metabolism and transport in pigs, sixty pregnant sows were assigned to 3 groups: the CON group was fed low-Ca diet with 11.25 g CaCO3 at 0600 h and 1500 h, H-L group was fed low-Ca diet with 22.5 g CaCO3 at 0600 h and low-Ca diet at 1500 h, and L-H group was fed low-Ca diet at 0600 h and low-Ca diet with 22.5 g CaCO3 at 1500 h, respectively. Serum from sows and umbilical cord and placenta were collected during delivery. Results showed that, compared with the CON group, H-L feeding significantly increased maternal serum total triglyceride (TG) and umbilical serum high-density lipoprotein (HDL) (P P P < 0.05). It is concluded that maternal supplementation with Ca varying with feeding time daily during late pregnancy affects placental lipid metabolism and transport in pigs by regulating the mRNA expression related to lipid metabolism and the circadian clock.
