The effects of increased hay-to-grain ratio on behavior, metabolic health measures, and fecal bacterial communities in four Masai giraffe (Giraffa camelopardalis tippelskirchi) at Cleveland Metroparks Zoo

We evaluated whether increasing the hay-to-grain ratio offered to Masai giraffe (Giraffa camelopardalis tippelskirchi) at Cleveland Metroparks Zoo would reduce oral stereotypies and alter feeding behaviors, maintain or increase serum calcium-to-phosphorus ratio, decrease serum insulin-to-glucose ratio and salivary insulin, and alter fecal bacterial community structure. Giraffe transitioned to a ∼90:10 hay-to-grain ratio in even increments […]

Urinary steroid evaluations to monitor ovarian function in exotic ungulates: II. Comparison between the giraffe (giraffa camelopardalis) and the okapi (okapia johnstoni)

Ovarian activity in the female giraffe was evaluated during the nonfertile ovarian cycle and during the terminal stages of gestation. Progesterone metabolites, in the form of pregnanediol‐3‐glucuronide (PdG), were measured in daily random urine samples collected from four adult parous giraffes. The follicular phase averaged 4.0 ± 0.1 days in length (N = 12; range […]

Preliminary study on the urine proteome of giraffes (Giraffa camelopardalis)

Data on proteinuria are lacking in giraffes, therefore the aim of our research was to study urine proteome with sensitive analytical methods to obtain important information regarding not only the kidney function but also the general health status. Twenty-nine samples were collected during 2013 and 2014, through non-invasive methods (from the ground by a syringe) […]
