ANNANDALE, C H; SCHULMAN, M L  and  KIRKPATRICK, R D. The use of electrochemically activated saline as a uterine instillation in pony mares. J. S. Afr. Vet. Assoc. [online]. 2008, vol.79, n.1, pp.36-38. ISSN 2224-9435.

Twelve pony mares were randomly assigned to either a control or a treatment group and inseminated with fresh, raw semen from a single stallion of known fertility in a cross-over trial design. Pregnancy was diagnosed by transrectal ultrasound 12-14 days post-ovulation and then terminated by administration of a luteolytic dose of cloprostenol. Treatment mares received a uterine instillation of 100 ml of electrochemically activated (ECA) saline 4-12 hours post-insemination. Control mares received no treatment post-insemination. Per cycle pregnancy rate was 58.3 % in the control group and 50 % in the treatment group. There was no statistical difference (P = 1.000) in pregnancy rate between the 2 groups. The principles of ECA and applications of ECA saline are discussed.
