摘要

本試驗旨在探討墊料材質對雞糞墊料堆肥化處理及其成分之影響。採用飼養Cobb品系白肉雞720隻，逢機分置在4種不同墊料材質組（A、B、C及D組依稻殼：稻蒿容積比例分別為100：0、75：25、50：50及25：75），白肉雞飼養至第39日齡結束，收集期間所產生的雞糞墊料，依組別進行堆肥化處理，分析堆肥化前、堆肥化第14天及堆肥化後之成分變化。結果顯示，各組在堆肥化過程發酵溫度達55℃以上者皆超過15天。雞糞墊料經堆肥化處理14天，除了D組苜蓿外，各組苜蓿及油菜的種子相對發芽率皆達90%以上，銅濃度約為堆肥化前的1.20－1.42倍，鋅濃度則為堆肥化前的1.18－1.34倍。經過40天的堆肥化處理後，各組乾物質損失率在35.07－48.24%之間，種子相對發芽率皆達95%以上，銅濃度約為堆肥化前的1.20－1.63倍，鋅濃度則為堆肥化前的1.32－1.66倍。綜合以上結果，利用稻蒿替代稻殼作為肉雞墊料，對雞糞墊料堆肥化處理過程無明顯之影響。

The purpose of this study is to investigate the effects of bedding materials on the composting process and compost compositions of poultry litter. A total of 720 one-day-old broilers were assigned to four treatments with different volume ratio of rice hull: rice straw as bedding material i.e., 100:0 (group A; control group), 75:25 (group B), 50:50 (group C) and 25:75 (group D). The feeding period was terminated when the age of broilers reached 39-day-old. The poultry litter was collected and treated with the composting process. The composition of compost piles were analyzed before composting, the 14th day of composting and after composting. The results showed that the fermentation temperature reached 55ºC for more than 15 days in each group. At 14th day of composting, alfalfa relative seed germination rates (RSG) of group D was 83.95%, while RSG of alfalfa and rapeseed all reached over 90%. The copper and zinc contents of poultry litter after composting were 1.20 to 1.42 times and 1.18 to 1.34 times of those before composting, respectively. During the composting period, the dry matter loss of poultry litter was 35.07 to 48.24%. After composting treatment 40 days, the RSGs of alfalfa and rapeseed all reached over 95% in all groups. The copper and zinc concentrations of poultry litter compost were 1.20 to 1.63 times and 1.32 to 1.66 times of those before composting, respectively. In conclusion, using rice straw to replace rice hull as bedding material do not affect the composting process.
