Abstract: 分析简阳大耳山羊不同年龄性别组粪尿养分含量的变化,为降低粪尿排放造成的污染和调配科学高效的饲料配方提供依据.试验山羊按年龄、性别分为A,B,C和D四个组,采用ICP-OES 6300 Radial测定有机质、全氮、全钾,并参照NY525-2002《有机化肥》评价分析.结果显示,1岁组山羊粪有机质、全氮、全钾含量均高于3岁组,公山羊组中全氮、全钾含量高于母山羊组.结论,简阳大耳山羊不同年龄、性别粪、尿中养分含量有较大差异.建议根据国家《畜禽养殖业污染物排放标准》(GB18596-2001)和国家《污水综合排放标准》(GB 8978-1996)和NY/T816-2004肉羊饲料标准拟定适合不同年龄性别山羊的饲料配比.
