Kangaroos can reduce environmental impact of farming

MELBOURNE: Kangaroos who consume less water and energy than sheep can reduce environmental impact of farming, a recent Australian survey has found.

According to University of Sydney, the study that tracked and recorded Kangaroos energy requirements concluded that kangaroos consumed only about 13% as much water as sheep and has vital implications for grazing practices.

Adam Munn, a lecturer in Sydney's faculty of veterinary science, spent five weeks on the study, 'The Australian' report said here.

He hoped his research will encourage greater uses for kangaroos. "With climate change, most rangelands are going to need to look at diverse options for land management for sustainability," he says.

Knowing the reduced impact of kangaroos on the environment gives graziers these options. "You could use kangaroos for eco-tourism without the environmental impact once thought, or increase the use of kangaroo for human and pet food consumption."

A sheep's diet consists mainly of saltbush. "Sheep feeding on saltbush will drink around 12 litres of water a day, as opposed to kangaroos, which drink around 1.5 litres per day," Munn said adding 'The discrepancy between the water requirements is attributed to their different diets and bodily functions. Kangaroos are better at concentrating their urine, and sheep eat more saltbush."
