复合酸化剂和益生素对仔猪腹泻防治效果研究

仔猪腹泻是猪场的常发疾病。选择32-33 d,均重8.2 kg的仔猪35头,在配合饲料中分别添加0.5%复合酸、1.5%益生素、0.5%复合酸＋1.5%益生素进行了对比试验。结果发现,添加1.5%益生素可显著提高仔猪采食量（P〈0.05）,分别单独添加复合酸和益生素仔猪末重最佳（P〈0.05）。两种添加剂均可显著降低腹泻率（P〈0.05）。未发现添加复合酸和益生素对生产性能的加性效应,可能与该添加剂的使用剂量有关。

Study on the Effect of Compound Acids and Probiotics on Piglet Diarrhea

Piglet diarrhea has become a common phenomenon which was caused from many aspects in the production of swine. A trial was designed as 0.5% Compound Acids, 1.5% Probiotics, or 0.5% Compound Acids and 1.5% Probiotics were applied in complete feed respectively to feed piglet（35, average weight 8.2 kg, 32±1 days age）. The results indicate that the intake of piglet significantly increase when 1.5% Probiotics supplied （ P〈0.05 ） ,and the final weight shows best in treatment of Compound Acids or Probiotics supplied （ P 〈 0.05 ）,and these additives can observably depress the diarrhea--probability. But the additive effect was little observed when both applied, probably affected by the dosage of additives.
