Influence of two different feeding strategies in the dry period on dry matter intake and plasma protein peroxidative and antioxidative profile during dry period and early lactation

摘要

( ) dry matter intake (DMI) (kg/animal/day); ( ) energy intake (EI) (MJ/animal/day); Mean concentrations ± SE of [ ] bityrosine bridges (BIT) (mgx10 /g Plasmaprotein); ( ) formylkinurine (FK) (mgx10 /g Plasmaprotein); ( ) total antioxidant capacity (TAC) (μmol/g Plasmaprotein); ( ) sulfhydryl residues (SH) (mmolx10 /g Plasmaprotein) in blood plasma of “one-phase” and “two-phase” fed cows from five weeks a.p. up to six weeks p.p.. Results of the SAS mixed model indicating significant (p<0.05) differences regarding the fixed effects of group, time and group × time are shown in the respective tables under the graphs. * indicates significant differences between groups
