Abstract The objective was to evaluate the fermentation parameters, chemical composition and in situ degradability of sesame silage in comparison to usual silages. The losses, fermentation quality and chemical composition of the forages and silages were evaluated using a completely randomised design with four treatments (sesame, corn, millet and sunflower) and four replicates per treatment, the silages were produced in experimental silos. In-situ degradability was evaluated using a completely randomised design with four treatments and three replicates (animals) per treatment. The results were statistically evaluated by analysis of variance and Tukey’s test with a level of 5% of probability. Three rumen fistulated non-castrated Santa Inês rams were used. Sunflower and corn silages presented higher percentages of losses through gases (p = .0256). Millet silage presented higher losses by effluent (p < .0001). The dry matter recovery (p < .0001) ranged from 70.0 to 96.5% for sesame and corn silage, respectively. The dry matter content (p = .0002) in the silages ranged from 280.0 to 429.4 g kg−1. The sesame silage presented loss amounts and fermentation parameters similar to those found in corn and sunflower silage. Sesame silage showed moderate dry matter (DM), content, excellent crude protein (CP) and total digestible nutrients (TDN) contents, and low lignin content. Corn silage presented higher concentration of the soluble fraction of DM (p < .0001). The sesame silage presented a high degradability rate of DM and it was similar to corn and millet which have great nutritional potential for ruminants feeding. Sesame has the potential to produce quality biomass and silage for animal feeding. highlights The sesame can be an option for silage making. Sesame helps to ensure sustainability by promoting lower seasonal risks in this region through the usage of silage as feed for the animals. Sesame also increases the productivity of livestock throughout the year, through the availability of feed for the herd mainly during the dry season of the year.

与普通青贮相比，芝麻青贮的发酵特性和营养价值

摘要 目的是评价芝麻青贮与普通青贮相比的发酵参数、化学成分和原位降解性。使用完全随机设计的四种处理（芝麻、玉米、小米和向日葵）和每个处理四个重复，评估了饲料和青贮饲料的损失、发酵质量和化学成分，青贮饲料在试验筒仓中生产。使用完全随机设计评估原位降解性，每个处理有四个处理和三个重复（动物）。结果通过方差分析和 Tukey 检验以 5% 的概率水平进行统计评估。使用了三只瘤胃瘘管未阉割的 Santa Inês 公羊。向日葵和玉米青贮饲料的气体损失百分比较高 (p = .0256)。小米青贮饲料的流出物损失较高（p < .0001）。芝麻和玉米青贮饲料的干物质回收率 (p < .0001) 分别为 70.0% 至 96.5%。青贮饲料中的干物质含量 (p = .0002) 范围为 280.0 至 429.4 g kg-1。芝麻青贮的损失量和发酵参数与玉米和向日葵青贮中发现的相似。芝麻青贮显示出中等的干物质 (DM)、含量、优良的粗蛋白 (CP) 和总可消化营养素 (TDN) 含量，以及低木质素含量。玉米青贮饲料的 DM 可溶性部分浓度较高（p < .0001）。芝麻青贮饲料对DM的降解率高，与玉米、小米相似，对反刍动物具有很大的营养潜力。芝麻具有生产用于动物饲养的优质生物质和青贮饲料的潜力。亮点 芝麻可以作为青贮饲料制作的一种选择。芝麻通过使用青贮饲料作为动物饲料来降低该地区的季节性风险，从而有助于确保可持续性。芝麻还通过主要在一年的旱季为牲畜提供​​饲料，全年提高牲畜的生产力。
