title: Investigation into homocysteine [corrected], vitamin E and malondialdehyde as indicators of successful artificial insemination in synchronized buffalo cows (Bubalus bubalis).
abstract: The aim of this study was to describe modifications in plasma homocysteine (Hcy), vitamin E (VitE) and malondialdehyde (MDA) concentrations in the first 56 days after artificial insemination (AI) in buffalo. Thirty-five buffalo cows were divided, ex post, into three groups on the basis of pregnancy diagnosis: pregnant, not pregnant, with embryonic mortality. Pregnancy was diagnosed by ultrasonography and plasma concentrations of pregnancy-associated glycoproteins (PAGs). Our results showed that, in pregnant buffaloes, included those with embryonic mortality, MDA increased progressively while VitE decreased. In non-pregnant buffaloes, MDA and Vit E were unchanged. Hcy concentrations also remained unchanged within each group throughout the study period, but were lower in non-pregnant buffaloes than in the pregnant ones and in those with embryonic mortality. In conclusion, present data suggest that successful pregnancy in buffalo cows might be linked to Hcy metabolism and oxidative stress involvement.
