摘要
上海地区引种林麝取得成功后，首次进行了饲料营养对麝香产量和品质影响的研究。试验麝饲养在上海市郊崇明岛东平林场，进行分期对比试验。分别用青绿饲料、青绿饲料加低蛋白饲料、青绿饲料加高蛋白饲料、配合饲料饲喂受试麝，考察饲料营养对麝香产量和质量的影响。结果表明，饲料营养显著影响麝香产量和品质。单独饲喂青绿饲料不能满足泌香的营养需要，平均产香量３．２１ｇ，麝香色深而湿、品质差。提高营养水平后，麝香产量显著提高，品质也有所改善，其中以配合饲料效果最好。使用配合饲料不仅产香量提高，品质好，而且个体间差异小。初次泌香的一龄个体产香量达到１４．４ｇ，群体平均产量达到１３．４７５ｇ，在试验前的基础上提高３１９．７８％，分别比安徽、陕西和四川饲养群提高１４．９７％、６４．３３％和８．５８％。使用配合饲料来提高林麝麝香产量潜力很大。
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.
