Premature hippo calf at Cincinnati Zoo receives round-the-clock care

CINCINNATI (AP) — The Cincinnati Zoo says a prematurely born baby hippo is making progress toward standing on her own.

The zoo says the calf born early Tuesday is starting to support her weight for a few seconds at a time.

Zoo spokeswoman Michelle Curley said Saturday the hippo has gained almost 4 pounds since birth but is still about 20 pounds under the low end of a normal birth weight of 55 to 120 pounds for a Nile hippo.

Curley says the hippo continues to receive 24-hour-a-day care including exercises to help strengthen her muscles.

The zoo says 17-year-old Bibi gave birth six weeks early to the first Nile hippo born there in 75 years.
