Abstract In recent years, the interest to grow sorghum for silage has increased, with greater prominence in areas where water supply and or availability is an issue for plant growth. Therefore, the objective of this study was to evaluate the effects of sorghum cultivars (forage or sudan), storage length and microbial inoculation with heterofermentative and facultative homofermentative inoculants on the fermentation profile, DM loss, aerobic stability and ruminal in situ starch disappearance of whole-plant sorghum silage. Whole-plant sorghum (279 ± 37 g/kg DM for forage and 232 ± 29 g/kg DM for sudan) was ensiled in quintuplicate 20 L plastic buckets untreated (CON) or after the following treatments: Lactobacillus plantarum CH6072, L. plantarum LSI, and Pediococcus pentosaceus P6 at 1 × 105 cfu/g of fresh forage (LPPP); L. buchneri LB1819 and Lactococcus lactis O224 at 1.5 × 105 cfu/g (LBLL). Silos were allowed to ferment for 0, 15, 30 or 90 d. Lactic acid and total acids were greatest in sudan sorghum silage, and total acids were greatest in LPPP and lowest for LBLL. Ammonia-N (as g/kg of total N) was greatest with sudan sorghum. The acetic acid was greatest in forage sorghum inoculated with LBLL, intermediate in sudan sorghum inoculated with LBLL, and linearly increased in both cultivars with storage length from 15 to 90 d. Silage aerobic stability was greater for LBLL compared to CON and LPPP. Ruminal in situ starch disappearance was increased with ensiling time, and linearly increased from d 15–90. Microbial inoculation with L. buchneri and Lactococcus lactis increased the acetic acid concentrations, improved aerobic stability, and reduced the DM loss by discarded visible spoilage, at the expense of higher DM loss by gases. This effect was more evident in forage sorghum compared to sudan sorghum.

短文：高粱品种、青贮贮藏时间和微生物接种对全株高粱青贮发酵曲线、氮组分、瘤胃原位淀粉消失和有氧稳定性的影响

摘要 近年来，种植高粱用于青贮饲料的兴趣有所增加，在水供应和/或可用性是植物生长问题的地区尤为突出。因此，本研究的目的是评估高粱栽培品种（饲草或苏丹）、储存时间和微生物接种异种发酵和兼性同发酵接种物对发酵曲线、干物质损失、需氧稳定性和瘤胃原位淀粉消失的影响。 - 种植高粱青贮。将整株高粱（草料为 279 ± 37 g/kg DM，苏丹为 232 ± 29 g/kg DM）在未经处理 (CON) 或以下处理后的五份 20 L 塑料桶中青贮：植物乳杆菌 CH6072、植物乳杆菌LSI 和戊糖片球菌 P6，1 × 105 cfu/g 新鲜草料 (LPPP)；L。buchneri LB1819 和乳酸乳球菌 O224，浓度为 1.5 × 105 cfu/g (LBLL)。让筒仓发酵 0、15、30 或 90 天。苏丹高粱青贮饲料的乳酸和总酸含量最高，LPPP 的总酸含量最高，LBLL 的总酸含量最低。苏丹高粱的氨氮（以总 N 的 g/kg 计）最高。醋酸在接种LBLL 的饲用高粱中最高，在接种LBLL 的苏丹高粱中居中，并且在贮藏时间为15 至90 d 的两个品种中均呈线性增加。与 CON 和 LPPP 相比，LBLL 的青贮有氧稳定性更高。瘤胃原位淀粉消失随着青贮时间的增加而增加，并从第 15-90 天线性增加。用布氏乳杆菌和乳酸乳球菌接种微生物会增加乙酸浓度，改善需氧稳定性，并通过丢弃可见的腐败物来减少 DM 损失，代价是气体造成的 DM 损失更高。与苏丹高粱相比，这种效果在饲用高粱中更为明显。
