Physiology and modulation factors of ovulation in rabbit reproduction management

Rabbit is an induced ovulatory species, so ovulation takes place after mating. Traditionally, exogenous and synthetic hormonal factors (administered by intramuscular intravaginal route) such as GnRH analogues, or different physical procedures (i.e. stimulation cannula) have been used to induce in females when artificial insemination applied rabbit farms. Restriction public rejection of the use hormones leading study seminal plasma components with potential action on induction. The aim present review collect summarise strategies recent years trigger improve fertility management respect more animal-friendly manipulation methods. Furthermore, special attention has paid a semen component (as endogen molecule) beta nerve growth factor (β-NGF) male female reproductive physiology. This neurotrophin its receptors (TrKA p75NTR) are abundantly distributed both tracts, it seems important physiological role sperm maturation behaviour (velocity, apoptosis capacitation), well modulatory ovulation. Endogen β-NGF diluted doses extenders; hence could be considered innovative alternative strategy avoid current (by stressful treatments Their addition dose animal welfare
