The multi-agency operation at Gelligaer Common led by the RSPCA lasted 2 days.
One bay mare was put to sleep since of “serious health issues” and to “prevent further suffering.”
The RSPCA is now appealing for details to learn who these ponies come from.
RSPCA inspector, Christine McNeil, said: “We’d like to assure the general public that these ponies are being well took care of and are getting treatment.
“It is really sad to see the well-being problems these ponies deal with.

“As ever we’re very grateful for the support from the local authority and other equine charities from the National Equine Welfare Council for pulling together to help them.”
Officers from the RSPCA, Caerphilly County Borough Council and other members of the National Equine Welfare Council (NEWC) – Redwings, World Horse Welfare, The British Horse Society, The Donkey Sanctuary, Bransby Horses and Horseworld signed up with forces on April 4 and 5.
The action by the charities is the 4th operation in 8 weeks.
The RSPCA verified to the Argus recently that the ponies well-being is a “priority “and that they “are in a place of safety.”

National Equine Welfare Council director Kirsty Withnall said: “This operation at Gelligaer Common was another prime example of our strong collaboration working, and what we can accomplish together for animal well-being.
“If you are aware of any of the owners of these ponies, we urge you to contact the RSPCA.”
In March the RSPCA got rid of 12 ponies from Gelligaer Common on well-being premises – with one needing to be put to sleep to end its suffering.
The ponies gotten rid of were a bay mare with a brown foal, a grey mare with a bay foal, a bay mare with a bay foal and a bay child, a chestnut mare, a grey mare and a grey roan foal and an orphan chestnut foal.
RSPCA Cymru has today introduced a brand-new report highlighting an “urgent need” to manage animal well-being facilities.
RSPCA head of public affairs David Bowles said: “While lots of owners of sanctuaries and other animal well-being facilities do a remarkable job for animal well-being, the absence of guideline and oversight has actually long been a significant issue for the RSPCA.
“Our officers have too often dealt with situations that have spiralled out of control – with capacity, governance and financial issues all a reality for many sanctuaries; demonstrating the urgent need for regulation.”
