He added: "I was very unhappy with some of the imported snakes as they were dehydrated and covered in parasites.
"Back in the early 1980s, breeding snakes was a rare event but there was a handful of enthusiasts in the UK and USA making headway and we shared what we learnt. King cobras are cannibalistic snakes. To get a pair together without cannibalism is difficult. You need to get the female in with the male without her showing signs of aggression."
During the interview, Mr Yeomans insisted that the snakes posed no threat to him, although he admitted he had been bitten twice before.
He said: "These king cobras know I provide them with food and fresh water so they're not going to go out of their way to do harm to me when I do no harm to them whatsoever. People say I'm mad but it's better than saying that you're bad and everything I do is good. My life is about the conservation of the king cobra."
His fascination with the king cobra came after studying it in its natural environment.
He founded the Agumbe Rainforest Research Station in India in 2005, a centre dedicated to the conservation of the snake and its habitat.
The king cobra is one of the most dangerous snakes to inhabit the forests of Asia and is reputed to be able to kill an elephant.
