摘要

試驗在探討母豬餵飼液體醱酵飼料對哺乳仔豬之腸道細菌、免疫反應及生長性能之影響。利用12頭2～6胎次母豬於分娩前一週逢機分配至試驗組（液體醱酵飼料組）和乾料組。液體醱酵飼料是以1:2.5比例混合飼料與水，並添加乳酸桿菌和枯草桿菌（10 5 cfu mL -1）於室溫醱酵24小時後餵飼。母豬飼料餵量依仔豬數作調整，每日分二次供給。試驗結果顯示，試驗組母豬糞便中乳酸桿菌數目顯著（P＜0.05）低於乾料組的母豬，並且糞便中乳酸、丙酸和丁酸顯著（P＜0.05）高於乾料組的母豬。試驗組出生仔豬體重顯著（P＜0.05）低於乾料組，但出生4週後增重有較乾料組佳之趨勢。試驗組仔豬在第4週時血清IgG量顯著（P＜0.05）高於乾料組。仔豬糞便中乳酸桿菌和大腸菌群比值兩組間無差異，但試驗組仔豬糞便中乳酸含量則顯著（P＜0.05）高於乾料組，而丁酸含量顯著低於（P＜0.05）乾料組；糞便中醋酸和丙酸含量二組之間無差異性。母豬餵飼液體醱酵飼料對其哺乳仔豬糞便中有機酸和血清IgG含量及增重均有正面的反應。

This study examined the effect of sow fed fermented liquid feed (FLF) on the fecal bacteria, immune response and growth performance of nursing piglets. Twelve multiparous sows were randomly allocated to the experimental (fermented liquid feed) or control group (dry feed, DF) for 1 week prior to farrowing and for 4 weeks after parturition. Fermented liquid feed was prepared by mixing dry feed and water at a ratio of 1:2.5. The mixture was allowed to ferment by adding Lactobacillus and Bacillus (10 5 cfu mL -1) at a temperature of 25℃ for 24 hours prior to first feeding. The amount of feed for each sow was adjusted to according to their number of piglets and supplied twice a day. The results demonstrated fecal excretion from sows fed FLF had significantly (P＜0.05) lower numbers of Lactobacillus than sows fed DF and sows fed FLF had significantly (P＜0.01) higher concentration of lactic acid, propionic acid and butyric acid than sows fed DF. Although the birth weight of piglets from sows fed FLF was significantly (P＜0.05) lower than piglets from sows fed DF, the weight gain of piglets from sows fed FLF tended to be higher than piglets from sows fed DF after 4 weeks from birth. The IgG concentration of piglets from sows fed FLF was significantly higher than piglets from sows fed DF 4 weeks after birth. The ratio of Lactobacillus and coliform did not significantly differ between the two groups. The fecal lactic acid concentration in piglets from sows fed FLF was significantly (P ＜0.05) higher than piglets from sows fed DF. The fecal butyric acid concentration in piglets from sows fed FLF was significantly (P ＜ 0.05) lower than piglets from sows fed DF, but the fecal acetic acid and propionic acid concentration showed no significant difference between the two groups. In conclusion, sows fed FLF influenced their piglets in terms of fecal organic acid, Ig G concentration and weight gain.
