A historic castle has offered up its bamboo plantation to help feed two giant pandas destined for Edinburgh Zoo.

Kelburn Estate and Country Centre in Ayrshire said the zoo can have unlimited free access to its crop.

Breeding pair Tian Tian and Yang Guang, the first giant pandas to live in the UK for 17 years, are expected to come to Scotland at the end of the year under an historic agreement with China.

Zookeepers must ensure they have enough food for the pandas, which each munch between 20kg and 30kg of bamboo every day.

Zoo officials say they are considering Kelburn's offer, as well as other offers from around the UK.

The estate is home to Patrick Boyle, the Earl of Glasgow. He said: "When we heard Edinburgh Zoo was having difficulty in locating sufficient quantities of bamboo, we got in touch as we have plenty to spare.

"It was brought to the estate by my great-grandfather, the 7th Earl, the governor of New Zealand between 1892 and 1897, and my great-grandmother, the Countess, a keen gardener. On their return to Britain they stopped at several locations in the Orient where she collected a great variety of plants, including several species of bamboo.

"I'm happy for the zoo to have as much of our bamboo as it needs at no cost. Being able to help keep these wonderful creatures in Scotland is reward enough for us."

The estate has around 51 square metres of three types of bamboo, thanks to a relatively mild coastal climate because of the gulfstream.

A spokesman for the Royal Zoological Society of Scotland, which owns the zoo, said: "We are naturally grateful to everyone who has offered support and have been following up the options with a view to assessing feasibility and how they might fit with our overall plans.

"No single voluntary source will be able to meet the scale of what is required."
