Abstract: The first study of nutrition effect on musk secretion in musk deer (Moschus berezovskii) was performed after they were introduced into Shanghai,China.The tested deer were bred at Chongming Island,fed separately with silage,silage plus low-protein concentrate,silage plus high-protein concentrate,and compound feed.Then,the influence of forage nutrition on musk secretion was studied.The conclusion was that high nutrition level could promote quantity and quality of musk secretion for breeding forest musk deer.In the compound feed test period,musk secretion reached 13.475 g/ind.,increased 319.78% on previous production,and 14.97%,64.33%,and 8.58% on musk production of populations bred in Anhui Province,Shaanxi Province and Sichuan Province separately,where there were the three largest musk deer breeding farms in China.The prospect for using compound forage to increase musk secretion is magnificent according to this research.
