摘要

有機酸已經廣泛的添加在家畜飼料中來取代抗生素的使用。本篇論文之目的在探討添加有機酸對於母豬生殖道的健康、行為與血液性狀之影響。試驗一共使用十頭母豬來進行試驗。平均體重為237公斤。逢機分配至兩個處理組，處理一為對照組，處理二為對照組飼糧並添加0.4％的混和酸，一天餵飼兩次分別為早上六點及下午六點。試驗二使用16隻LYD之三品種雜交母豬逢機分配至四個處理組中。處理一為對照組，處理二為對照組添加0.1％混合酸，處理三為對照組添加0.2％混合酸，處理四為對照組添加0.4％混合酸。試驗期間測定其陰道之pH,尿液Ph及總生菌數。結果顯示：陰道及尿液之pH並不恆定，週與週之間有差異。與前四週相比，第五週之尿液之pH有顯著的差異。在第23週時尿液之pH與其他週相比也是差異顯著，例如第三週及第十七週。與對照組相比之下在陰道之pH也有相似的結果。添加0.4％混合酸處理組之溫度與陰道pH與對照組相比，也有顯著之差異。總而言之，添加0.4％混合酸處理組會使得尿液pH增加，而陰道pH降低。隨著添加的酸比例越高，血液中的葡萄糖則越少。添加酸的比例越高喝水的行為會增加，排尿行為上升以及攝食行為上升。而當添加的酸越多，血液中的pH也會越低。

Organic acids have been widely used as feed to replace antibiotics in livestock feeds. The objective of this study was to investigate the influence of organic acid supplementation on the growth performance, health of the reproductive tract, behavior and blood characteristics of the pig. Two experiments were carried out to investigate the influence of organic acid supplementation on the growth performance, health and reproductive tract of the pigs. In Experiment 1 a total of multiparious 10 pigs were used. Average initial weight was 237 kg. Sows were assigned to two different treatments. Dietary treatment were: 1) control, 2) control+0.4% organic acid-based blend (fumaric acid, citric acid, phosphoric acid, malic acid and fatty acids matrix) offered twice daily at 6:00 and 18:00 h. In Experiment 2, a total of 16 (Landrace x Yorkshire x Duroc) gilts (average age 6 month of age) were randomly assigned to 4 treatments in an experiment. Pigs were divided into the following 4 treatments: 1) control (basal diet), 2) control + 0.1% Tetracid, 3) control + 0.2% Tetracid, and 4) control + 0.4% Tetracid. Parameters measured were vagina pH, urine pH and bacteria count. The pH of urine and vagina were not constant, they are very different within weeks. At week 5, there were significant difference (P<0.001) in the urine pH as compared to week 1 to 4. During the 23 week period, there were significant differences (P<0.01) in the urine pH measurement, for example at wk 3 and wk 17.
Similarly for the vagina pH, there were significant differences in the vagina pH measurement (P<0.01) as compared to control. Temperature and vagina pH also showed significant differences (P<0.001) for pig treated with 0.4% as compared to the control throughout the duration of the experiment. In conclusion, addition of 0.4% tetracid increased urine pH and decreased vagina pH. Blood glucose of the none supplemented (control) treatment increased while that of the tetracid fed group decreased with increasing level of supplementation. Higher concentration of tetracid increased drinking but the lower concentration and the control group decreased. Similarly, higher concentration of tetracid increased urination. Tetracid supplementation seems to influence appetite and thus increased eating across all the treated groups. Blood pH decreased for all treatments with lower values from the higher concentration of tetracid.
