I scratch the belly of a Guinea Hog lying down on his side while zookeeper Liz trains him to accept a blood draw. The Oakland Zoo’s Veterinary Care Center wants a blood sample to determine if the animals’ new diet has the proper nutrients. To prepare the two Guinea Hogs for an actual blood draw, they first have to become tolerant about a person holding off their leg to find the vein. Due to their excellent sense of smell, Jason and Sara initially were nervous about the rubbing alcohol on their legs. Also, the zookeeper practiced touching their legs with a blunted needle to accustom them to the motions of a blood draw. Some of the zoo’s visitors who saw us practicing in the exhibit appeared surprised that the pigs were so tolerant and even asked if the Guinea Hogs were sedated. Nope, they weren’t. They simply enjoy their belly rubs and are willing to lie down on the grass.
The less glamorous aspects of my internship are the routine cleaning and disinfecting of the animals’ exhibits and night houses. I completely gutted and disinfected the rabbits’ night house, and then I filled it would fresh shavings and grass hay. The other intern and I also scrubbed the pools in the pigs’ exhibit along with disinfecting their night house and service area.
The past few days have been warm and sunny – the perfect opportunity for making popsicles for the lemurs! A lemur enrichment popsicle consists of fruit chucks (usually grapes, watermelon, strawberries and cantaloupe) frozen in ice.
Besides continuing to conduct lemur observations for an intern project, I attended an intern class about zoological population management. This class concludes the series of intern classes and explained how zoos determine which animals to breed and to whom to breed them. The class covered what is included in a stud book and general population management concepts, like avoidance of inbreeding. I learned the founding populations in a stud book are animals directly from the wild.
Another guideline was not to keep all animals of one species concentrated in one zoo. In case of an emergency, zoos would not want all the animals of a particular species to die.
