摘要

本試驗旨在探討臺灣水鹿產茸期餵飼發酵飼料（fermented feedstuff, FF）與納豆菌及真菌發酵產物（natto and fungal fermentative products, NF）對鹿茸生產性能及免疫力之影響。本試驗利用臺灣水鹿公鹿12隻，依據個體前次鹿茸重量及年齡進行分組，分為對照組、發酵飼料組（添加1%之發酵飼料）、納豆菌及真菌發酵產物組（添加1%之發酵飼料及0.15%之納豆菌及真菌發酵產物）共3組，於產茸期進行餵飼試驗，試驗平均長茸期為70天，試驗期間飼糧及飲水採任食。試驗結果顯示，臺灣水鹿產茸期之體增重於各組間並無顯著差異，但飼料乾物質採食量佔體重比例，則以發酵飼料組顯著較其他組為低（P＜0.05）。鹿茸重量及鹿茸增幅於組間雖未達統計差異，但發酵飼料組之鹿茸重量及鹿茸增幅有提升之趨勢。鹿茸乾物質之灰分及磷含量，在發酵飼料組與納豆菌及真菌發酵產物組均顯著高於對照組（P＜0.05），鈣含量亦有提升之趨勢。血液中免疫球蛋白濃度於試驗前後，各組間均無顯著差異。綜合試驗結果，添加1%之發酵飼料於臺灣水鹿產茸期飼料中，具有顯著增加鹿茸灰分和磷含量，與增加鹿茸產量之趨勢。

The purpose of this study was to determine the effect of fermented feedstuff (FF) and natto and fungal fermentative products (NF) during velvet growing phase on the antler velvet performance and immunity in Formosan sambar deer. Based on the age and previous antler performance, 12 male deer was divided into 3 groups utilizing block randomization, which were control, FF (containing 1% of FF), and NF (containing 1% of FF and 0.15% of NF) group, each group was fed different concentrated feed. The average antler develop period was 70 days, feed and water was provided ad libitum. The results showed that the body weight gain were no significant difference between groups, yet the dry matter intake / body weight was significant decreased (P ＜ 0.05) in FF group. The antler velvet weight and growing rate were no significant difference between groups but largely increased in FF group. The crude ash and phosphorous content of antler velvet dry matter were both significantly increased in FF and NF group (P ＜ 0.05), and calcium content of antler velvet dry matter was also markedly elevated. The concentrations of immunoglobulins were no significant difference between groups. Taken together, by using 1% of FF during velvet growing phase, the mineral concentration of antler velvet was significantly increased and antler velvet growing potential was markedly elevated in Formosan sambar deer.
