Rosemary (Rosmarinus officinalis L.) extract (RE) has multiple pharmacological and biological activities, including the use as a food additive and medicine. This study was conducted to investigate the effects of dietary RE supplementation on the growth performance, nutrient digestibility, antioxidant capacity, intestinal morphology, and microbiota of weaning piglets. A total of 192 crossbred weaned piglets [Duroc × (Large White × Landrace)] (initial body weight = 6.65 ± 0.33 kg, weaned days = 23 ± 1 d) were group housed (six pigs per pen; n = 8 pens/treatment). Pigs were fed a corn–soybean meal-based control diet or the basal diet supplemented with 100, 200, or 400 mg/kg RE. Pigs were allowed ad libitum access to fed for 21 d. The growth performance and apparent total tract digestibility of nutrients, and intestinal morphology and antioxidant status were evaluated. The components of the microbial microflora were also determined in the cecal samples. Compared with the control, dietary supplementation with RE increased the final body weight, average daily gain, and average daily feed intake (linear, P = 0.038, 0.016, and 0.009, respectively), and decreased the diarrhea ratio in piglets (linear, P < 0.05). The digestibility of crude protein (linear, P = 0.034) and gross energy (linear, P = 0.046) increased with treatment with RE. Piglets fed RE showed longer villus height (linear, P = 0.037 and 0.028, respectively) and villus height/crypt depth (linear, P = 0.004 and 0.012; quadratic, P = 0.023 and 0.036, respectively) in the jejunum and ileum, in addition to a lesser crypt depth in the jejunum (linear, P = 0.019) and ileum (quadratic, P = 0.042). The addition of RE increased the activity of superoxide dismutase (linear, P = 0.035 and 0.008, respectively) and glutathione peroxidase activity (linear, P = 0.027 and 0.039, respectively) and decreased the content of malondialdehyde (linear, P = 0.041 and 0.013; quadratic, P = 0.023 and 0.005, respectively) in the serum and liver. Dietary RE supplementation, compared with the control, increased the number of Bifidobacterium (linear, P = 0.034) and Bacteroidetes (linear, P = 0.029), while decreased Escherichia coli (linear, P = 0.008; quadratic, P = 0.014) in the cecal contents. Thus, dietary RE supplementation can improve growth performance, nutrient digestibility, antioxidant capacity, intestinal morphology, and the microbiota in weaned piglets, and 200 mg/kg may be considered the optimum dosage.

添加迷迭香提取物对断奶仔猪生长性能、营养消化率、抗氧化能力、肠道形态和微生物群的影响

迷迭香 (Rosmarinus officinalis L.) 提取物 (RE) 具有多种药理和生物活性,包括用作食品添加剂和药物。本研究旨在研究日粮添加稀土对断奶仔猪生长性能、营养消化率、抗氧化能力、肠道形态和微生物群的影响。共有 192 头杂交断奶仔猪 [杜洛克 ×(大白 × 长白)](初始体重 = 6.65 ± 0.33 kg,断奶天数 = 23 ± 1 天)被分组饲养(每栏 6 头猪;n = 8 栏/处理)。猪饲喂以玉米豆粕为主的对照日粮或添加 100、200 或 400 mg/kg RE 的基础日粮。允许猪随意采食21 d。养分的生长性能和表观全消化道消化率,并评估肠道形态和抗氧化状态。还确定了盲肠样品中微生物菌群的成分。与对照相比,添加 RE 的日粮增加了最终体重、平均日增重和平均日采食量(分别为线性,P = 0.038、0.016 和 0.009),并降低了仔猪的腹泻率(线性,P <0.05)。粗蛋白(线性,P = 0.034)和总能量(线性,P = 0.046)的消化率随 RE 处理而增加。饲喂 RE 的仔猪在空肠和回肠中表现出更长的绒毛高度(线性,分别为 P = 0.037 和 0.028)和绒毛高度/隐窝深度(线性,P = 0.004 和 0.012;二次方,分别为 P = 0.023 和 0.036)。除了空肠(线性,P = 0.019)和回肠(二次,P = 0.042)。RE的添加增加了超氧化物歧化酶的活性(线性,分别为P = 0.035和0.008)和谷胱甘肽过氧化物酶的活性(线性,分别为P = 0.027和0.039)并降低了丙二醛的含量(线性,P = 0.041和0.013) ;二次方,P = 0.023 和 0.005,分别)在血清和肝脏中。与对照组相比,膳食补充 RE 增加了双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,而减少了大肠杆菌(线性,P = 0.008;二次方,P = 0.014)的数量。盲肠内容物。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。RE的添加增加了超氧化物歧化酶的活性(线性,分别为P = 0.035和0.008)和谷胱甘肽过氧化物酶的活性(线性,分别为P = 0.027和0.039)并降低了丙二醛的含量(线性,P = 0.041和0.013) ;二次方,P = 0.023 和 0.005,分别)在血清和肝脏中。与对照组相比,膳食补充 RE 增加了双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,而减少了大肠杆菌(线性,P = 0.008;二次方,P = 0.014)的数量。盲肠内容物。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。RE的添加增加了超氧化物歧化酶的活性(线性,分别为P = 0.035和0.008)和谷胱甘肽过氧化物酶的活性(线性,分别为P = 0.027和0.039)并降低了丙二醛的含量(线性,P = 0.041和0.013) ;二次方,P = 0.023 和 0.005,分别)在血清和肝脏中。与对照组相比,膳食补充 RE 增加了双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,而减少了大肠杆菌(线性,P = 0.008;二次方,P = 0.014)的数量。盲肠内容物。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。P = 0.035 和 0.008)和谷胱甘肽过氧化物酶活性(线性,分别 P = 0.027 和 0.039)并降低丙二醛的含量(线性, P = 0.041 和 0.013;二次方,分别 P = 0.023 和 0.005)血清和肝脏。与对照组相比,膳食补充 RE 增加了双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,而减少了大肠杆菌(线性,P = 0.008;二次方,P = 0.014)的数量。盲肠内容物。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。P = 0.035 和 0.008)和谷胱甘肽过氧化物酶活性(线性,分别 P = 0.027 和 0.039)并降低丙二醛的含量(线性, P = 0.041 和 0.013;二次方,分别 P = 0.023 和 0.005)血清和肝脏。与对照组相比,膳食补充 RE 增加了双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,而减少了大肠杆菌(线性,P = 0.008;二次方,P = 0.014)的数量。盲肠内容物。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。分别)并降低血清和肝脏中丙二醛的含量(线性,P = 0.041 和 0.013;二次,分别 P = 0.023 和 0.005)。与对照组相比,膳食补充 RE 增加了双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,而减少了大肠杆菌(线性,P = 0.008;二次方,P = 0.014)的数量。盲肠内容物。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。分别)并降低血清和肝脏中丙二醛的含量(线性,P = 0.041 和 0.013;二次,分别 P = 0.023 和 0.005)。与对照组相比,膳食补充 RE 增加了双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,而减少了大肠杆菌(线性,P = 0.008;二次方,P = 0.014)的数量。盲肠内容物。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。增加了盲肠内容物中双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,同时减少了大肠杆菌(线性,P = 0.008;二次,P = 0.014)。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。增加了盲肠内容物中双歧杆菌(线性,P = 0.034)和拟杆菌(线性,P = 0.029)的数量,同时减少了大肠杆菌(线性,P = 0.008;二次,P = 0.014)。因此,日粮添加稀土可以改善断奶仔猪的生长性能、营养物质消化率、抗氧化能力、肠道形态和微生物群,200 mg/kg可能被认为是最佳剂量。
