Artificially extended photoperiod administered to pre-partum mares via blue light to a single eye : observations on gestation length, foal birth weight and foal hair coat at birth

Nolan, Margaret Bethaline; Walsh, Caroline M.; Duff, Noelle; McCrarren, Conor; Prendergast, Ralph L.; Murphy, Barbara A. (Elsevier, 2017-09)

In seasonally breeding animals, photoperiod perception is crucial for timing of important physiological events. In the horse, long day photoperiod influences the onset of ovulation and cyclicity, shedding of the heavier ...
Efficacy and safety of recombinant zona pellucida vaccines in domestic horse mares and current application of native porcine zona pellucida vaccines in African elephant cows

Nolan, Margaret Bethaline (University of Pretoria, 2019)

The use of immunocontraceptives in veterinary population management and wildlife fertility control is well-established. The porcine zona pellucida (pZP) vaccine has been successfully used in approximately 85 species. The ...
Ovarian function following immunocontraceptive vaccination of mares using native porcine and recombinant zona pellucida vaccines formulated with a non-Freund's adjuvant and anti-GnRH vaccines

Nolan, Margaret Bethaline; Bertschinger, Hendrik Jan; Roth, Robyn; Crampton, Michael; Martins, I.S. (Isabela); Fosgate, Geoffrey Theodore; Stout, T.A.E. (Tom); Schulman, M.L. (Martin) (Elsevier, 2018-10-15)

An important determinant in the selection of any contraceptive agent is the impact on ovarian function, both in the short and longer term. In this study, ovarian activity was monitored in mares immunised with one of the ...
Researching immunocontraceptive vaccines with mares (Equus caballus) as both a target and model for African elephant (Loxodonta africana) cows : a review

Joonè, Carolynne J.; Nolan, Margaret Bethaline; Bertschinger, Hendrik Jan; Schulman, M.L. (Martin) (Elsevier, 2019-08)

A sequence of studies is reviewed that reported the domestic horse (Equus caballus) mare as an appropriate and accessible research platform for recording clinical and laboratory data post-immunisation with anti- GnRH and ...
Serum antibody immunoreactivity and safety of native porcine and recombinant zona pellucida vaccines formulated with a non-Freund’s adjuvant in horses

Nolan, Margaret Bethaline; Schulman, M.L. (Martin); Botha, A.E. (Alma); Human, Anne-Marie; Roth, Robyn; Crampton, Michael C.; Bertschinger, Hendrik Jan (Elsevier, 2019-02)

Commercial and regulatory limitations associated with native porcine zona pellucida (pZP) vaccines formulated with Freund’s adjuvants may be overcome by developing effective recombinant ZP vaccines (reZP) and identifying ...
