Milk composition of white rhinoceros over lactation and comparison with other Perissodactyla

Milk composition of white rhinoceros over lactation and comparison with other Perissodactyla

The proximate composition of milk from fifteen free‐ranging white rhinoceroses at different lactation stages is reported with detailed analysis of fatty acid composition and minerals. Lactose is the main component at 7.93 ± 0.53%, followed by 0.93 ± 0.19% protein, 1.76 ± 0.39% fat, 0.40 ± 0.18% ash,...

Description
Summary:The proximate composition of milk from fifteen free‐ranging white rhinoceroses at different lactation stages is reported with detailed analysis of fatty acid composition and minerals. Lactose is the main component at 7.93 ± 0.53%, followed by 0.93 ± 0.19% protein, 1.76 ± 0.39% fat, 0.40 ± 0.18% ash, 0.05 ± 0.01% glucose, and 0.04 ± 0.02% non protein nitrogen The interindividual variation of all the components is high, showing no trend of change over lactation. The K and P content decreased over lactation. The fatty acid composition of rhinoceros milk is characteristic with a high saturated fatty acids content of 62%–84%, of which the medium chain fatty acids form the major portion. The C10:0, C12:0, C16:0, and C18:1c9 are the major fatty acids in the milk fat. The results are compared with the two other Perissodactylae families, the Equidae and Tapiridae. Differences in gross composition are small, but the milk of the Rhinocerotidae have the lowest gross energy, while the milk fats consist of the highest amounts of saturated fatty acids, while the low levels of C16:1c9 and C18:1c9 indicate the lowest mammary Δ9‐desaturase activity. White rhino milk. Composition almost unchanged over lactation. Lactose as major component. Lower gross energy than Equidae and Tapiridae. Research highlights The milk composition of fifteen white rhinoceroses at different stages of lactation was analyzed. Lactose is the major component. The milk composition was almost unchanged over lactation and had a lower gross energy than milk of Equidae and Tapiridae.
