Vascular endothelial growth factor: A novel marker for torsion-induced incomplete cervical dilatation in Egyptian buffaloes.

Background: Uterine torsion, the most complicated cause of maternal dystocia recorded in bovine, usually followed by incomplete cervical dilatation after successful detorsion, which interfere with vaginal fetal delivery.

Aim: This study aimed to evaluate the histopathological changes, variable collagen concentrations, and vascular endothelial growth factor expressions in uterine and cervical tissues following successful detorsion.

Methods: Animals were classified into four groups; normally calved cases (group A), cases that respond successfully to detorsion and followed by vaginal fetal delivery without (group B) or with (group C) cervical laceration, and cases that suffered from failure of complete cervical dilatation after successful detorsion (group D).

Influence of antepartum administration of immunopotentiators on reproductive efficacy of buffalo and viability of their newborn.

The authors determine the efficacy of prepartum immunopotentiators administered during late gestation on postpartum fertility, IgG levels and calf viability. Fifty buffalo were divided into five groups (10 animals in each group). Group I was the control group.
