摘要
用4.3%的尿素处理麦秸36d,可使粗蛋白质含量提高1.2倍,半纤维素含量降低13.6%;采食混合日粮的绵羊对氨化麦秸的采食量提高54%;氰化处理可使麦秸的脆性提高,有利于物理性消化。
Wheat straw was treated with 4.3g urea/100g straw for36 days. Results indicated that its crude protein content increased by 120%; hemi-cellulose decreased by 13.6%; intake of ammoniated wheat straw increased 54% by sheep feeding mixed diets; fragility of wheat straw was increased by ammonia treatment, helpful physical digestion.
