 deer (Moschus moschiferus) is now domesticated in China for musk production and is a resource with a promising future. Also, sambar deer (Cervus unicolor), Asia's largest deer, may prove useful in husbandry. Several deer species are being farmed in New Zealand and ruse deer (Cervus rusa), which are native to South and Southeast Asia, are being farmed in Mauritius, Australia, and Papua New Guinea for meat and medicinal by-products. Two small, goat-sized Asian deer, the hog deer (Cervus porcinus) and the barking deer (Muntiacus muntjak), may also be worth considering.
