摘　　要：[ Objective] To provide a reference for understand effects of acidifiers on digestibility of lambs. [Method] Feeding experiment as well as digestion and metabolism experiment was conducted to evaluate effects of supplementing acidifiers on ultra-early weaned lambs. [ Result] Diets of ultra-early weaned lambs supplemented with acidifiers greatly improved their production performance and increased digestibility of feed. However, different acidifier products had certainly various effects on lambs. Acidifier product I increased weight gain, feed conversion ratio and apparent di- gestibility of main nutrients more greatly than acidifier product II did, while the result was contrary in reducing diarrhea incidence. [ Conclusion] Whether the acidifiers can increase digestibility of nutrients or not is still uncertain and needs further studies.[ Objective] To provide a reference for understand effects of acidifiers on digestibility of lambs.
