Numerous studies have demonstrated that is an unconventional feed resource with significant developmental potential. This research aimed to explore the effects of silage on the growth performance, blood parameters, immunity, antioxidation, cytokine levels, and rumen bacterial composition of Kazakh lamb. Forty healthy male Kazakh lambs, aged 5 months and weighing 30.12 ± 1.14 kg, were randomly divided into control and experimental groups, each consisting of four replicates (five lambs per replicate). The control group was fed a basal diet, while the experimental group received a diet supplemented with 20% silage (dry matter basis). Following a 10-day pre-feeding period, a 60-day formal experiment was conducted. The results indicated no significant difference in growth performance between the experimental and control groups. However, compared to the control group, the use of silage significantly reduced ( < 0.05) neutrophil, lymphocyte, and eosinophil counts, as well as creatinine levels in the blood. Furthermore, silage ( < 0.01) enhanced total serum antioxidant capacity, superoxide dismutase, catalase, glutathione peroxidase, immunoglobulin A, immunoglobulin M, immunoglobulin G, interleukin-2, interleukin-6, and interleukin-8, and decreased malondialdehyde and interleukin-4 levels. Additionally, the use of silage increased the diversity and richness of the rumen bacterial community, notably enhancing the relative abundance of such as and . In conclusion, feeding Kazakh lamb with silage (20% DM) did not adversely affect their growth performance but improved their immunity and antioxidant capacity and enhanced the relative abundance of beneficial bacteria in the rumen, thereby promoting animal health.
大量研究表明，[具体物质名称]是一种具有巨大发展潜力的非常规饲料资源。本研究旨在探讨[具体物质名称]青贮饲料对哈萨克羔羊生长性能、血液参数、免疫力、抗氧化能力、细胞因子水平和瘤胃细菌组成的影响。40只健康的5月龄哈萨克雄性羔羊，体重30.12±1.14 kg，随机分为对照组和实验组，每组4个重复（每个重复5只羔羊）。对照组饲喂基础日粮，实验组饲喂添加20%[具体物质名称]青贮饲料（干物质基础）的日粮。经过10天的预饲期后，进行了60天的正式试验。结果表明，实验组和对照组的生长性能没有显著差异。然而，与对照组相比，使用[具体物质名称]青贮饲料显著降低了（P<0.05）血液中的中性粒细胞、淋巴细胞和嗜酸性粒细胞计数以及肌酐水平。此外，[具体物质名称]青贮饲料（P<0.01）提高了血清总抗氧化能力、超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶、免疫球蛋白A、免疫球蛋白M、免疫球蛋白G、白细胞介素-2、白细胞介素-6和白细胞介素-8，并降低了丙二醛和白细胞介素-4水平。此外，使用[具体物质名称]青贮饲料增加了瘤胃细菌群落的多样性和丰富度，显著提高了如[具体细菌名称1]和[具体细菌名称2]等有益菌的相对丰度。总之，给哈萨克羔羊饲喂20%干物质的[具体物质名称]青贮饲料不会对其生长性能产生不利影响，反而提高了它们的免疫力和抗氧化能力，并增加了瘤胃中有益菌的相对丰度，从而促进了动物健康。
