A sample of milk was obtained from a giraffe while under anaesthesia for a minor operation. Since we have been unable to find any previous reports on the composition of giraffe's milk, we present here our findings for the chemical composition and vitamin content of this one sample taken during the fifth month of lactation.
1. A sample of milk was obtained from a giraffe on the 150th day of lactation. The milk was analysed for fat, lactose, protein, casein, soluble proteins, nonprotein nitrogen, ash, calcium, phosphorus, sodium, potassium, chloride, magnesium and iron. The main characteristic of the milk was its high fat content, 12.5 per cent.
2. The soluble-protein fraction was examined by paper electrophoresis and found to be of a complex nature with both globulins and albumins present.
3. The contents of Ca pantothenate, riboflavin, thiamine and vitamin B6 (pyridoxal) were similar to those in good quality cow's milk. The contents of biotin and α-tocopherol were lower and those of nicotinic acid, vitamin B12 and vitamin A higher than in cow's milk. No carotenoids were present.
