| Abstract (English): |
This experiment was conducted to investigate the effects of different leaves on feed intake, nutrient apparent digestibility and nitrogen balance in forest musk deer. Twelve male forest musk deers (Moschus Berezovskii) of similar age and good health were used in a 6×6 Latin square design with 2 replicates per group. The ration consists of base material and the leaves. Green rattan, mulberry leaves, triangular maple leaves, elm leaves, Melia azedarach leaves and mixture of the above five leaves in equal proportion were used in each group. The results showed as follows: ① the intake of base material and leaves in mulberry leaves group had no significant difference from those in other groups (P>0.05). The intake of total ration in mulberry leaves group was significantly lower than that in mixed group (P<0.05), but had no significant difference with the rest groups (P>0.05). ② The apparent digestibility of dry crude protein (CP), crude ash, calcium, carbohydrate (CHO), total energy (GE) and neutral detergent fiber (NDF) in mulberry leaves group were significantly higher than those in other groups (P<0.05). ③ The retention nitrogen and nitrogen utilization in mulberry leaves group were higher than those in other groups (P<0.05). It is concluded that the apparent digestibility and nitrogen utilization of ration are higher in mulberry leaves group. [ABSTRACT FROM AUTHOR] |

试验旨在研究不同种类树叶饲料对林麝营养物质表观消化率和氮平衡的影响。选取 12 头 年龄相同、体况良好的雄性林麝[体重 (8.0±0.5) kg], 随机分为 6 组。试验采用 6×6 拉丁方设计, 整个 试验期为 84 d, 共分为 6 期, 每期 14 d (预试期 11 d, 正试期 3 d), 按照树叶饲料种类分为青皮藤组、桑 树叶组、三角枫叶组、榆树叶组、苦楝树叶组及以上树叶等比混合的混合叶组, 共 6 组。结果表明: ① 桑树叶组基础饲粮和树叶采食量与其他组差异不显著 (P>0.05); 桑树叶组日粮采食总量显著低于 混合树叶组 (P<0.05), 但与其他组差异不显著 (P>0.05)。② 日粮粗蛋白 (CP) 、粗灰分 (Ash) 、钙 (Ca) 、 碳水化合物 (CHO) 、总能 (GE) 、中性洗涤纤维 (NDF) 表观消化率以桑树叶组较高 (P<0.05)。③ 桑树 叶组沉积氮和氮利用率较高 (P<0.05)。由此可见, 林麝以桑树叶为粗饲料时日粮表观消化率和氮利 用率较高。 [ABSTRACT FROM AUTHOR] |
