PRAGUE, Jan 3 (Reuters) - When you’re an endangered species and your partner just isn’t in the mood, drastic measures are called for, as Ginni, one of Prague Zoo’s Asiatic lionesses, found out on Thursday when she underwent an artificial insemination procedure.
The attempt was a last-ditch effort after failed hopes the zoo’s three cats, male Jamvan and females Ginni and Suchi brought from India in 2015, would procreate naturally and widen the European gene pool of the animals.
“Jamvan is not dominant enough, he is not willing to mate or when he tries, they chase him away,” Prague Zoo mammals curator Pavel Brandl told reporters.
The Asiatic lion is slightly smaller than its African relative and while the wild population has recovered somewhat, it still only numbers around 600 in the Gir Protected Area in India’s Gujarat, its only natural habitat.
The big cats are vulnerable to poaching as well as illness, with 24 dying last year due to one bout of disease, Prague Zoo said. There are 143 living in captivity in Europe but all are bred from 11 ancestors, limiting the gene pool.
“The timing was perfect... the insertion was perfect,” said Thomas Hildebrand, head of department for reproduction management at Leibniz Institute for Wildlife Research in Berlin, and one of the team of Czech and German experts that carried out the procedure.
“The semen was collected from the male (lion) and the placement of the semen was all how we desired. We are quite hopeful this is a success,” he added.
His Czech colleague sounded a more cautious note however.
“In general we can say that the chance is smaller in comparison with natural copulation. We have to wish a lot that it turns out well,” said Prague Zoo Chief Veterinarian Roman Vodicka.
The process has been used previously in large mammals including elephants or rhinoceroses, but is rare for big cats.
An African lioness in South Africa gave birth to the world’s first lion cubs born through artificial insemination in September, the University of Pretoria, which led the procedure, said at the time. (Writing by Jan Lopatka; Editing by Kirsten Donovan)
