ABSTRACT
Löhrke B, Viergutz T, Kanitz W, Göllnitz K, Becker F, Hurtienne A, Schweigert FJ., High milk yield in cows with oxidant stress, Onl
J Vet Res.,
30 (4): 253-259,
2026. Oxidant
stress during early lactation is associated with increased metabolism for production
of milk. Hydroperoxides (HP) were determined by oxidation
of Fe2+ in low density lipoproteins (LDL) by ultracentrifugation of serum and
precipitation. First 8 and second parity 5 Holstein cows at lactation by 53 ±
1.4 days postpartum had HP 0.1 and 2.1µM. We found correlations between HP and
daily milk yield of
r = 0.86, P = 0.0004 and milk energy output (r = 0.64, P = 0.04). We find that
endogenous oxidation of LDL in cows is associated with higher productivity.
