El Toro 3

Electronic Ejaculator and Immobiliser
for bulls and rams


El Toro 3 Carry Case

The El Toro 3 Electro-Ejaculator is a manually operated electronic electro-ejaculator, suitable for semen collection from bulls and rams using a rectal probe.

It incorporates a rear-end immobiliser using the same probe.

The El Toro 3 is powered by rechargeable batteries with enough reserve to enable a full days work if required. A mains powered charger is supplied for recharging purposes.

It is supplied in a black and silver aluminium carry case, along with a 70mm diameter probe for bulls, 2 cables for connecting the probe to the control box, a mains charger and some small accessories. The case measures approximately 47x37x17cm and weighs about 9.5 kg.

This highly successful, technically and electronically advanced device offers a choice of two ejaculation modes to minimise stress in the animal, yet obtain superior results from even the most difficult.

Designed and manufactured by ERG, it is the culmination of our 25 years experience in this field.

Built in the same rugged style as the previous El Toro models, it is even more robust and has improved looks.

An immobilizer mode for the hind quarters is a boon for maintenance procedures such as sheath washing etc.

The control unit is compatible with all the El Toro 2 accessories which provides an economical upgrade path for existing customers.
