【摘要】：本研究以添加单一及混合中药渣于全株玉米(Zea mays)青贮中,通过对青贮料感官品质、发酵品质及营养成分的分析,探讨中药渣在全株玉米青贮饲料调制中的应用。全株青贮玉米铡短至1.5~2cm,均匀混入药渣制作青贮,玻璃缸青贮300d开盖,取样进行感官评定、发酵品质和营养成分测定。结果表明,混合药渣组感官品质为一般质量青贮料,添加水平5%时青贮料粗蛋白(CP)、粗脂肪(EE)、磷含量(P)显著高于未添加对照组(CK)及添加水平7%、10%(P0.05),氨态氮/总氮(NH3-N/TN)比值显著低于对照组(P0.05),添加水平为5%时乳酸(LA)、丙酸(PA)含量显著高于添加水平7%、10%(P0.05);单一药渣组中,党参(Codonopsis pilosula)、川芎(Ligusticum wallichii)及牛蒡(Arctium lappa)药渣组感官品质均在2级及以上,党参药渣组添加水平为5%时,干物质(DM)、CP显著高于对照组(无添加)及同水平其他处理组(P0.05),LA、PA含量显著高于添加水平7%、10%(P0.05);牛蒡药渣组各添加水平下,DM、CP及P含量显著高于对照组(P0.05),NH3-N/TN显著低于对照组(P0.05),且LA随添加量显著增大(P0.05);川芎药渣组各添加水平下,CP、P含量及EE显著高于对照组(P0.05),NH3-N/TN显著低于对照组(P0.05),乙酸(AA)显著高于同水平其它处理组(P0.05)。综上,混合药渣、党参药渣组添加水平5%时,对青贮品质改善效果较好,牛蒡药渣及川芎药渣有益于青贮品质的改善,但牛蒡药渣对青贮的改善效果优于川芎药渣。
[Abstract]:In this study, the sensory quality, fermentation quality and nutrient composition of the silage were analyzed by adding a single and mixed Chinese medicine residue to the whole plant Zea mays silage. The application of traditional Chinese medicine residue in the preparation of whole plant corn silage was discussed. The whole plant silage corn guillotine was as short as 1.52cm. The silage was made by mixing the silage evenly and the glass cylinder silage was opened for 300d. The sensory evaluation, fermentation quality and nutrient composition were determined. The sensory quality of the mixed residue group was the silage of general quality. The contents of crude protein, crude fat, phosphorus and phosphorus in silage were significantly higher than those in control group (CK) and the addition level of 71010 / P0.05U, the ratio of ammonia nitrogen to total nitrogen (NH3-N / TNN) was significantly lower than that of the control group (P0.05N), and the contents of lactic acid, lactic acid, propionate and PAA were significantly lower than those of the control group at the addition level of 5. It was significantly higher than the addition level of 7% and 10% P0.05%; in the single drug residue group, The sensory quality of Codonopsis pilosulai, Ligusticum wallichiiand Arctium lappai) of Codonopsis pilosulae and Arctium lappai were all above the 2nd grade, and the additive level of Codonopsis pilosulae, Ligusticum wallichii and Arctium lappai was 5. The CP content of DMN in DMC was significantly higher than that in control group (without addition) and other treatments at the same level, and the contents of DMC and P in Arctium lappa group were significantly higher than those in control group (P 0.05), and the contents of P and P were significantly higher in Arctium burdock dregs group than in control group (P 0.05), and were significantly lower than that in control group (P0.05N / TN), and were significantly lower than those in control group (P 0.05N / N / TN, P 0.05N / TN, P < 0.05). The contents of CPP and EE in ligustraum chuanxiong residue group were significantly higher than those in control group (P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, P 0.05N / TN, respectively). When the mixed residue and Codonopsis lanceolata were added at 5 levels, the effect of improving the silage quality was better. The effect of burdock residue and Chuanxiong medicinal dregs was beneficial to the improvement of silage quality, but the improvement effect of burdock residue on silage was better than that of Ligusticum chuanxiong dregs.
