提高飼糧鐵、硒或錳含量對仔豬生長性能、血液性狀與免疫反應之影響
Effects of high levels of dietary iron, selenium or manganese on growth performance, blood traits and immune response of piglets
摘要
為及早因應政府禁用抗生素作為畜禽生長促進劑，可能影響仔豬的生長與健康狀況，本試驗旨在運用提高飼糧鐵、硒與錳等含量，以提升仔豬的先天性免疫力，改善仔豬的生長性能與免疫力。試驗共採用48頭32－35日齡之LYD三品種雜交仔豬，依性別與體重4處理組，每處理6重複，每重複2頭（公母各半）。對照組飼糧含20%粗蛋白質與3,400 kcal/kg可消化能，鐵、硒與錳含量分別為140 mg/kg、0.15 mg/kg與20 mg/kg。三個處理組飼糧分別含2倍鐵、硒或錳，試驗共進行4週。試驗結果顯示，在餵飼仔豬鐵、硒和錳正常量與2倍量鐵、硒或錳飼糧，仔豬的體重、日增重、飼料採食量與飼料轉換率均無顯著差異。另外在仔豬血液性狀，亦不受飼糧處理的影響。在免疫反應，餵飼2倍硒飼糧，在免疫球蛋白IgA、IFN-γ、TNF-α與抗菌胜肽pBD-2濃度均顯著地高於對照組（P ＜ 0.05），而餵飼2倍鐵或錳飼糧與對照組比較，則無顯著差異。綜上結果顯示，餵飼2倍硒飼糧，雖然沒有顯著改善仔豬的生長性能，但有提升IgA、IFN-γ、TNF-α與抗菌胜肽pBD-2等性狀，有助於提升仔豬的免疫力。

The purpose of this experiment was to provide double amount of iron (Fe), selenium (Se) or manganese (Mn) in weaning pig diet to stimulate the growth and innate immunity. The experiment used 48 LYD crossbred piglets, aged 32-35 days. The pigs were divided into 24 pens by gender (half male and half female) and bodyweight, with 6 replicates per each treatment. The control diet contained 20% crude protein, 3,400 kcal/kg digestible energy, 140 mg/kg iron, 0.15 mg/ kg selenium and 20 mg/kg manganese. Three treatment diets contained double amount of iron, selenium or manganese, respectively. The experiment was implemented for 4 weeks. The results showed that feeding piglets with double amount of dietary iron, selenium or manganese had no effect on the daily weight gain, feed intake and feed conversion rate. Moreover, there was no difference found on blood traits of pigs. The concentrations of immunoglobulin, IgA, IFN-γ, TNF-α and the antimicrobial peptide pBD-2 (immune-related traits) of piglets fed with double amount of Se were remarkably higher than those fed with controlled diet. However, piglets fed with double amount of dietary Fe or Mn did not have a significant effect on the immune response when compared with feeding with controlled diet. In conclusion, the provision of double amount of Se in diet did not improve the growth performance of piglets but increased the IgA, IFN-γ, TNF-α concentration and the antibacterial peptide pBD-2 contents.
