    摘要:

    通过建立基于外貌性状的量化性体况评分标准,于2012年7-10月间对四川马尔康麝场的586头圈养林麝(雌麝299头,雄麝287头)进行了体况评分,并分析了相关变量对林麝体况得分的效应,结果表明:马尔康麝场圈养林麝的体况评分均值为3.49(±0.02,n=586),大部分林麝(59.56%,n=349)的体况评分高于均值。雌麝体况评分均值(3.50±0.02,n=299)略高于雄麝(3.49±0.03,n=287)(P > 0.05),成体麝体况评分(3.59±0.02,n=291)极显著地高于老龄林麝(3.38±0.09,n=27)和亚成林麝(3.35±0.03,n=184)(P < 0.01)。林麝的体况得分与其年龄相关不显著(r=0.07,P > 0.05),但亚成体及成体麝的体况评分与其年龄间的相关极显著(亚成体r=0.19,P < 0.01;成体r=-0.16,P < 0.01),而老龄麝体况评分与其年龄略呈负相关(r=-0.23,P > 0.05)。S模型y=e1.2811-0.0885/aR2=0.051,df=500,F=26.74,P < 0.01)可近似拟合林麝体况得分和年龄的关系。此外,马尔康麝场泥地基底的改装圈舍中的林麝体况(3.52±0.03,n=197)显著优于原装青砖圈舍林麝评分(3.47±0.02,n=389)(P < 0.05)。

    Abstract:

    The forest musk deer (Moschus berezovskii) has been endangered owing to the habitat loss and musk exploitation, and musk deer farming has become an effective measure to conserve wild populations and provide medicinal musk sustainably. In musk deer farming, the health condition of captive individuals will be closely related to the reproduction and the musk production. In this study, the body condition of captive forest musk deer (299 females and 287 males) in the Maerkang musk deer farm (MMF) was surveyed during July and October 2012, using the quantified criteria system. Furthermore, the potential effects of certain influencing factors were analyzed. The results showed that, the average body score of captive forest musk deer was 3.49 (±0.02, n=586), and most of individuals (59.56%, n=349) scored higher than the average. The body condition of all females (3.50±0.02) was better than that of all males (3.49±0.03), but the difference was not statistically significant (P > 0.05). The body condition of adults (4-9 years old) (3.59±0.02, n=291) was significantly better than that of older deer (older than 10 years) (3.38±0.09, n=27) and sub-adults (2-3 years old) (3.35±0.03, n=184; P < 0.01). No significant correlation was found between musk deer's body condition and age (r=0.07, P > 0.05), but the body condition scores of the adults and sub-adults were highly significantly correlated with the animals' age (sub-adults:r=0.19, P < 0.01; adults:r=-0.16, P < 0.01); moreover, a significant negative correlation was observed between old individuals' and their age (r=-0.23, P > 0.05). The S model y=e1.2811-0.0885/a (R2=0.051, df=500, F=26.74, P < 0.01) fitted the relationship between the score of captive deer and its age. Furthermore, the body condition score of musk deer in the enclosures with earth-ground was higher than those in the enclosures with brick-ground.
