環境豐富化對籠飼紐西蘭白兔行為健康與生長性狀之影響
The effect of environmental enrichment on the growth, health and behavior in New Zealand rabbits
摘要
本試驗目的在於建立友善飼養環境的相關數據，減少實驗動物飼養時的緊迫，以確保可靠的動物試驗結果。試驗以4週齡兔共36隻（公母各半），分別圈養於豐富化兔籠（EN）及一般商業飼養籠（UE）6週，以探討不同的飼養環境對兔隻生長、健康與行為方面的影響。試驗結果顯示，商用飼籠組母兔的飼料效率雖然在剛開始的4－5週、5－6週及6－7週均顯著（P＜0.05）優於豐富化兔籠組，不過大於7－8週後兩組不論公母都無顯著的差異。在血液生理值的分析結果，EN組公兔血中的血紅素及血球容積比顯著（P＜0.05）高於UE組。血液生化值方面，UE組公兔血清中的三酸甘油酯顯著（P＜0.05）高於EN組，而EN組公兔之麩胺酸丙酮酸轉胺酶（glutamate pyruvate transaminase, GPT）及麩胺醯轉胺酶（γ-glutamyltransferase, γ-GT）顯著高於UE組。行為表現分析方面：EN組公兔上午時段的休息行為顯著（P＜0.05）高於UE組，然UE組公兔之社交、探索及自理行為顯著（P＜0.05）高於EN組，EN組公兔中午及下午時段的跳躍行為則顯著（P＜0.05）高於UE組；另外EN組公兔下午時段飲水行為則顯著（P＜0.05）高於UE組；母兔在兩種環境下結果的則較一致，EN組中所有時段的跳躍行為均有顯著（P＜0.05）高於UE組的現象。本研究顯示豐富化的飼養環境對兔的生長性能影響不大，但可能影響兔的血液生理值及有助於兔隻展現跳躍行為的表現。

The study aims to establish data related to the friendly feeding environment and relieve stress on animals during the experiment, thereby to assure reliable animal test results. The study was conducted on 36 rabbits aged 4 weeks (half of which was male and the other half female), raised in enriched cages (EU) and un-enriched cages (UE) for 6 weeks to investigates the influence of rabbit growth, health and behavior in different feeding environments. The results showed that in spite of the significantly better feeding efficiency of the UE female rabbit group than the EN rabbit group between 4 - 5 week, 5 - 6 week and 6 - 7 week at the beginning, there was no significant difference between the two groups, regardless of male or female, after 7 - 8 week. The analysis of hematology assay indicated that the volumes of hemoglobin (Hgb) and hemotocrit (Hct) in male EN rabbits are significantly higher than those of UE group (P ＜ 0.05). In serum biochemistry assay, the levels of triglyceride (TG) are significant higher in male UE rabbits than that of EN group (P ＜ 0.05), but the levels of GOT and r-GT are significant higher in EN group than in UE group (P ＜ 0.05). For the results of behavior assay, more male rabbits rested in EN group than in UE group in the morning (P ＜ 0.05;however, the behaviors of social activity, exploration and self-grooming in UE male rabbits were more significant than those in EN group (P ＜ 0.05). More male rabbits were hopping in the EN group than in the UE group at noontime and in the afternoon (P ＜ 0.05); In addition, rabbits in EN group consumed more water than those in UE group in the afternoon (P ＜ 0.05). Female rabbits showed consistent behavior in different time periods, however, more female rabbits were in EN group were hopping more than the ones in UE group (P ＜ 0.05) at all time. In conclusion, enriched cage environment has more influence on the physiological values of blood and hopping behavior but not on the growth of rabbits.
