Effect of energy diet on the expression of PC and PEPCK mRNA in the liver of periparturient
Eimeria infections in cows in the periparturient
phase and their calves: oocyst excretion and levels of specific serum and colostrum antibodies.
Very rapid metabolic and hormonal changes occur in the periparturient
period, in which important events such as birth and involution of the uterus take place (Pryce et al.
Dietary effects of linseed on fatty acid composition of milk and on liver, adipose and mammary gland metabolism of periparturient
Reproduction is one of the key pillars of dairy production and reproductive performance is linked to periparturient
health problems (LeBlanc, 2008).
diseases and their effect on reproductive performance in five dairy herds.
For example, during the periparturient
period of high-producing dairy cows, significant amounts of non-esterified fatty acids (NEFA) are transported from adipose tissue to the liver to combat negative energy balance (Grummer, 1993).
A cross-sectional field study investigating the effect of periparturient
dietary management on ruminal pH in early lactation dairy cows.
Pathogenesis and therapeutic management of lactation failure in periparturient
During the periparturient
period, Cows in periparturient
period are in negative energy balance the feed intake does not meet the total energy demand that increased by ~4-fold during the onset of lactation (Bell, 1995; Bauman, 2000).
For instance, it was demonstrated that beneficial effects of silymarin has been proven in periparturient
dairy cows (Tedesco et al.
Therefore, negative energy balance during the periparturient
period causes mobilization of fat from tissue stores and the release of NEFA into the blood stream.
