Watch Animal Maternity

This time on Animal Maternity, Frankie the giraffe has given birth in the midst of the herd at Woburn Safari Park, just as her keepers wanted. But now she's being pestered for milk by all the other young giraffes meaning her newest baby can't get in to feed. All babies need their crucial first feed, or colostrum, which contains key antibodies to keep them well.

This time, nerves are being stretched to the limit at Banham Zoo as the team await the arrival of rare Sumatran tiger cubs. They're under round the clock surveillance as the team wait to see if mum Svetta will produce any babies and as her due date comes and goes the tension mounts. As well as being the world's largest cat, its one of the most endangered species on earth.

This time, Etna the cheetah should be expecting cubs - but there's no baby bump to give the game away. It's hard for her keepers to know and as her due date comes and goes, she's keeping them guessing. She's also moving house, to a new, quieter den that should be better suited as a maternity suite.

This time on Animal Maternity, it's a difficult day for Tom the vet as Ruby the bull terrier's labour takes an unexpected turn. Ruby's been rushed to the vet after her labour seemed to grind to a halt after the births of her first two puppies. She's clearly still in labour, but with nothing happening, she is in distress and any puppies she may still be carrying are in danger.

In this episode of Animal Maternity, its all hands on deck as a baby eland's entrance into the world is delayed. At West Midland Safari Park, Director of Wildlife Bob is worried about one of his antelopes. After 4 hours of labour, Jenny the eland's calf seems to be stuck, with only its hooves having made it out. Bob now faces making a decision about when he should intervene.

This time on Animal Maternity we're with the vets performing a potentially lifesaving caesarean section on a lemur whose pregnancy has turned into a medical emergency. Lalo the lemur's giving cause for concern, but surgery is a risky procedure - can the team save Lalo? And will her baby be born safe and sound?
