中文摘要 | 以生長試驗及代謝測定來探討仔豬飼糧中添加異麥芽寡醣(Isomalto-oligosaccharides, IMOS)對其生長性能、氮代謝及糞臭味之影響。所使用的異麥芽寡醣漿(IMOSS)含62.8%異麥芽寡醣,係以α-D-(1-6)葡萄糖鍵結合的寡醣。選取80頭離乳仔豬(體重8.6 kg),依性別及胎別分飼於20欄,逢機分飼處理飼糧,五種處理分別為飼糧添加:(1)0% IMOS(對照組);(2)0.6% IMOS;(3)1.2% IMOS;(4)0.6% IMOS +抗生素(含林可黴素及觀黴素各22mg/kg;(5)0.6% IMOS +雙叉乳桿菌(8×108 CFU/kg);以測定仔豬之生長性能等。另選取16頭仔豬(體重12.5kg)分別置於代謝架,分4組逢機飼予試驗飼糧,飼糧處理如生長試驗之1至4組,經適應5天後,各別收集排泄物5天,以測定氮代謝及糞臭味。試驗結果顯示IMOS或抗生素、乳桿菌之添加並不顯著影響仔豬之飼料攝食量、增重、增重/飼料及下痢指數等。仔豬氮蓄積率及豬糞臭味成分中的氨(NH3)、硫化氫(H2S)與一級胺(RNH2)的濃度在處理間並無顯著差異,但飼糧添加0.6% IMOS可降低(P<0.07)豬糞臭氣中乙硫醇(C2H5SH),但抗生素的添加並無此效果。 |
英文摘要 | The feeding trial and metabolism trial were conducted to evaluate the effect of dietary isomalto-oligosaccharides (IMOS) on growth performance, nitrogen metabolism and odor of excreta of weanling pigs. IMOS are oligosaccharides composed of glucose units bound by α-D-(1,6) linkage. In the feeding trial, 80 weanling pigs (average weight 8.6 kg) were assigned to 20 pens and allotted to one of five dietary treatments. The diets were control; control diets containing either 0.6% or 1.2% IMOS; control diets containing 0.6% IMOS and Bifidobacteria (8×108/kg) or antibioties (Lincomycin 22 mg/kg and Spectinomycin 22 mg/kg,). In the metabolism trial, 16 weanling pigs (average weight 12.5 kg) were housed in metabolic cages and allotted to one of four dietary treatments as those in feeding trial excluding the dietary treatment containing 0.6% IMOS with Bifidobacteria. Pigs were adapted for five days followed by a 5-day collection for measuring the nitrogen metabolism and odor of excreta of each pig. The results showed that there were no significant effects of IMOS or antibiotics or Bifidobacteria on ADG, ADFI, feed efficiency, nitrogen retention, scour scores and concentration of NH3, H2S, RNH2 in feces. The level of C2H5SH in the feces were decreased by the addition of 0.6% IMOS (P<0.07) but not antibiotics addition. |
