How much does a hippo weigh at birth
When it comes to the birth of a baby hippopotamus, one may wonder just how much they weigh. Typically, a baby hippo weighs between 55 and 110 pounds (25 to 50 kilograms) at birth. However, it is important to note that the specific weight can vary depending on the individual hippo and environmental factors. This range gives us an idea of what to expect when a new little hippo enters the world.
Hippo calves are relatively large compared to many other animal species, and they grow rapidly in the first few months of life. They gain weight quickly through their mother’s milk, which is rich in fat and nutrients. As they continue to grow, adult hippos can reach weights of up to 3,000 pounds (1,360 kilograms) or more.

Fiona was born six weeks prematurely on January 24, 2017, and weighed only 29 pounds, significantly less than the average birth weight of a hippopotamus, which is around 55-120 pounds. She was immediately placed in the zoo’s intensive care unit, where she received round-the-clock care from veterinarians and zoo staff. Over the next several months, Fiona battled various health challenges, including pneumonia and endothelial dysplasia, a condition that affects the lining of her blood vessels. Despite the odds against her, Fiona continued to fight and thrive, and eventually surpassed all expectations.

Fiona is so adorable it’s hard imagine her ever being the most dangerous animal in Africa. Since she has been raised so far with so much human contact I wonder if she will accepting of her caretakers and any other human that may come in contact with her

Our little Fiona is starting to look like a normal chunk-a-lunk baby hippo that is called a calf. Normal weight for a hippo calf at birth is 100 pounds. This little lady only weighed 29. Amazing care she has been given.
