Abstract

BACKGROUND

The aim of this study was to evaluate the effects of Korean Red Ginseng marc with aluminum sulfate as litter amendments on ammonia, soluble reactive phosphorus, and pathogen populations in poultry litters.

METHODS

Increasing levels of Korean Red Ginseng marc with aluminum sulfate were applied onto the surface of rice hull as a top-dress application; untreated rice hulls served as controls.

RESULTS

Treatment with Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate alone resulted in lower litter pH (p < 0.05), as compared with that of the controls. There were some differences (p < 0.05) between treatments with Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate alone and controls at 2-4 wk (not at 1 wk). Ammonia levels reduced on an average by 29%, 30%, and 32% for 10 g, 20 g Korean Red Ginseng marc with aluminum sulfate, and aluminum sulfate alone, respectively, as compared with controls at 4 wk. During the experiment, Korean Red Ginseng marc with aluminum sulfate or aluminum sulfate treatment had an effect (p < 0.05) on soluble reactive phosphorus content, as compared with the controls (not at 4 wk). A decrease in Salmonella enterica and Escherichia coli was observed (p < 0.05) in litter amended with both Korean Red Ginseng marc with aluminum sulfate and aluminum sulfate alone, as compared with the control, except at 1-3 wk for Salmonella enterica and 1 wk and 4 wk for Escherichia coli, respectively.

CONCLUSION

The results showed that using Korean Red Ginseng marc with aluminum sulfate (blends), which act as acidifying agents by reducing the pH of the litter, was equally effective as aluminum sulfate in reducing the environmental impact.

摘要

背景

本研究旨在评估添加硫酸铝的韩国红参渣对家禽垫料中氨、可溶性活性磷和病原菌数量的影响。

方法

将添加不同水平硫酸铝的韩国红参渣作为追肥施用于稻壳表面；未处理的稻壳作为对照。

结果

与对照相比，添加硫酸铝的韩国红参渣或单独使用硫酸铝处理均导致垫料pH值降低（p < 0.05）。添加硫酸铝的韩国红参渣或单独使用硫酸铝处理与对照在2 - 4周时存在一些差异（p < 0.05）（1周时无差异）。与4周时的对照相比，添加10 g、20 g硫酸铝的韩国红参渣和单独使用硫酸铝时，氨水平平均分别降低了29%、30%和32%。在实验期间，与对照相比，添加硫酸铝的韩国红参渣或硫酸铝处理对可溶性活性磷含量有影响（p < 0.05）（4周时无影响）。与对照相比，添加硫酸铝的韩国红参渣和单独使用硫酸铝处理的垫料中肠炎沙门氏菌和大肠杆菌数量均减少（p < 0.05），但肠炎沙门氏菌在1 - 3周、大肠杆菌在1周和4周时除外。
