本试验旨在探讨丹参提取物对其生长性能的影响,表观养分消化率,抗氧化能力,和羔羊的免疫功能。选择60只2月龄,体重20±2kg的雌性羔羊(中国美利奴羊),随机分为5组,每组12只。而对照组(CK)仅接受基础饲料,实验组在基础饲料中添加0.04mL/kg不同浓度的丹参提取物(CL1组),0.08mL/kg(CL2组),0.12mL/kg(CL3组),和0.16mL/kg(CL4组)。喂养期为85天,包括15天的预喂养和70天的常规喂养。在测试期间记录体重和采食量,并在试验结束时采血测定免疫和抗氧化指标。结果表明,与CK组相比,CL3组羔羊的平均日增重和平均日采食量显著增加(p<0.05)。此外,粗蛋白和中性洗涤纤维的养分表观消化率显著提高(p<0.05)。干物质,酸性洗涤纤维和乙醚提取物无显著差异(p>0.05)。血清超氧化物歧化酶水平,过氧化氢酶,谷胱甘肽过氧化物酶,与CK组相比,CL2,CL3和CL4组的抗氧化能力明显更高,而丙二醛水平显著降低(p<0.05)。血清免疫球蛋白A,免疫球蛋白G,免疫球蛋白M,干扰素-γ,CL2,CL3和CL4组的肿瘤坏死因子-α和白细胞介素-10水平显着升高,而白细胞介素-1β水平显着降低(p<0.05)。总之,在日粮中添加丹参提取物可促进羔羊的生长性能和营养消化。通过增加免疫球蛋白和细胞因子浓度来改善免疫应答。它通过增加羔羊的抗氧化酶活性来增强抗氧化状态。

The aim of this experiment is to explore the effects of salvia sclarea extract on the growth performance, apparent nutrient digestibility, antioxidant capacity, and immune function of
lambs. Sixty female lambs (Chinese Merino sheep) aged 2 months and weighing 20 ± 2 kg were selected and randomly divided into five groups of twelve
lambs in each. While the control group (CK) received only basal feed, the experimental group was supplemented with different concentrations of salvia sclarea extract in the basal feed at 0.04 mL/kg (group CL1), 0.08 mL/kg (group CL2), 0.12 mL/kg (group CL3), and 0.16 mL/kg (group CL4). The feeding period was 85 days, including 15 days of pre-feeding and 70 days of regular feeding. Body weight and feed intake were recorded during the test period, and blood was collected at the end of the test for the determination of immune and antioxidant indices. The results showed that the average daily gain and average daily feed intake of lambs were significantly increased in CL3 group compared to CK group (p < 0.05). Also, the apparent nutrient digestibility of crude protein and neutral detergent fiber was significantly increased (p < 0.05). The Dry matter, acid detergent fiber and Ether extract were not significantly different (p > 0.05). The serum levels of superoxide dismutase, catalase, glutathione peroxidase, and antioxidant capacity were significantly higher in the CL2, CL3, and CL4 groups compared to CK group, while malondialdehyde levels were significantly lower (p < 0.05). The serum levels of immune globulin A, immune globulin G, immune globulin M, interferon-γ, and interleukin-10 were significantly higher and the levels of tumor necrosis factor-α and interleukin-1β were significantly lower in the CL2, CL3, and CL4 groups (p < 0.05). In conclusion, the addition of salvia sclarea extract to the ration promotes growth performance and nutrient digestion in lambs. Improvement of immune response by increasing immunoglobulin and cytokine concentrations. And it enhances the antioxidant status by increasing the antioxidant enzyme activity in
lambs.
