Evaluation of Aluminum Chloride As an Effective Short-Term Solution for Reducing Odor - Causing Volatile Fatty Acids in Duck Litter

ABSTRACT This study evaluated the effects of aluminum chloride (AlCl3) on pH and volatile fatty acid levels in duck litter over the course of a three-week experimental period. Ninety one-day-old Pekin ducks (45 males and 45 females) were distributed into three treatments with three replicates each (10 ducks per replicate) using a completely randomized design. Two treatments were top-dressing duck litter with thin layers (1-2 cm) of 50 g or 100 g of AlCl3 per kg of litter, respectively; the control group received no litter treatment. Although no significant differences in propionic acid levels (p>0.05) were observed in any of the treatments, overall pH values for the 50 g and 100 g AlCl3 treatments were both lower (p

摘要 本研究评估了氯化铝（aluminum chloride, AlCl3）在为期三周的实验周期内对鸭垫料pH值与挥发性脂肪酸（volatile fatty acid）含量的影响。本研究选取90只1日龄北京鸭（公母各45只），采用完全随机设计将其分为3组，每组设置3个重复，每个重复饲养10只鸭子。其中2个处理组分别按每千克垫料添加50克或100克氯化铝，以1-2厘米薄层撒施于鸭垫料上；对照组不进行任何垫料处理。尽管各处理组的丙酸含量均无显著差异（p>0.05），但50g和100g氯化铝处理组的整体pH值均更低（p
