| 摘 要： | 试验通过添加不同种类的青贮剂研究其对晴隆白刺花青贮品质和营养价值的影响.试验设直接青贮、添加乳酸菌（1％FM）、纤维素酶（0.1％FM）、乳酸菌＋纤维素酶（1％ FM ＋0.1％ FM）、甲酸（6 mL/kg FM）、蔗糖（3％FM）及乳酸菌（1％FM）＋纤维素酶（0.1％FM）＋乳酸菌（1％FM）＋纤维素酶（0.1％FM）＋甲酸（6 mL/kg FM）＋蔗糖（3％ FM）7个处理.试验结果表明：青贮过程中pH值总体呈下降趋势,添加剂处理显著低于直接青贮,其中蔗糖的效果最为明显（pH值3.97）,乳酸菌＋纤维素酶＋甲酸＋蔗糖处理也低（pH值4.04）,品质较好;直接青贮的pH值相对较高（4.73）;青贮后晴隆白刺花的粗蛋白（CP）略有下降,乳酸菌＋纤维素酶＋甲酸＋蔗糖降幅最大,达11.18％,但CP含量仍较高,为15.41％,其他各处理CP均有所上升;单独青贮,晴隆白刺花的酸性洗涤纤维（ADF）虽略有增加,但粗纤维（CF）和中性洗涤纤维（NDF）均下降,且NDF降幅较大,达20.15％,而粗脂肪（EE）、无氮浸出物（NFE）含量相对增加,改善了晴隆白刺花的营养;各处理单宁含量均有所下降,其中甲酸处理的降幅最大,达47.83％,乳酸菌＋纤维素酶处理降幅相对较小.

| Abstract: | For studying the effect of different additives on silage on the silage quality and nutritional value of Qinglong Sophoraviciifolia, 7 treated groups were control group （CK）, lactic acid bacteria （1% FM） , cellulose （0.1% FM） , actic acid bacteria ＋cellulose （1% FM ＋0.1% FM） , formic acid （6 mL/kg FM）, saccharose （3% FM）, and actic acid bacteria （I%FM） ＋cellulose （0.1% FM） ＋ formic acid （6 mL/kg FM） ＋ saccharose （ 3 % FM ）. The results indicate that ： pH dropped during ensiling, and additives on silage was significantly lower than that of no additive. The saccharose treat had the most obvious effect （pH was 3.97 ）, the＂ actic acid bacteria ＋ cellulose ＋ formic acid ＋ saccharose＂ treat also had good effect （pH was d. 04）, and the pH of CK was 4.73. Nitraria crude protein flower （CP） decreased slightly after silage, The decreasing amplitude of CP of the＂actic acid bacteria ＋ cellulose ＋ formic acid ＋ saccharose＂treat decline sharpest （ 15.41% ）, but this treat still had higher content of CP （ CP was 15.41% ）, the CP content of other treats rose. ADF of CK has a slight increase, CF and NDF declined, and the maximum decreasing amplitude was NDF （20.15%）, the EE content and NFE content increased, nutritional value of Qinglong Sophoraviciifolia rose through silage. The tannin content decreased in all treats, and the maximum decreasing amplitude was the formic acid treat （47.83 % ）, and the smallest decreasing amplitude was the＂ actic acid bacteria ＋ cellulose＂ treat. |
