Abstract  

Fifty sows with similar body mass, parity and due dates were selected and randomly divided into five groups with five replicates per group and two sows per replicate. The sows in the control group were fed on a basal diet, and those in the experimental groups were fed on the basal diet supplemented with 50, 100, 150 and 200 mg/kg Callicarpa kwangtungensis Chun. extract, respectively, from the 30th day of gestation to the 25th day of lactation in order to investigate the effects of C. kwangtungensis extract on reproductive performance, immune function, antioxidant capacity and intestinal flora of sows. The results showed as follows: 1) Compared with the control group, dietary 50 and 100 mg/kg C. kwangtungensis extract significantly increased the birth body mass, and dietary 100 and 150 mg/kg C. kwangtungensis extract significantly increased the birth litter body mass, and dietary 150 mg/kg C. kwangtungensis extract significantly increased the weaning body mass and weaning litter body mass of piglets (P<0.05); 2) C. kwangtungensis extract could improve serum superoxide dismutase (SOD) activity and decrease malondialdehyde (MDA) content of sows at mid-gestation, farrowing and weaning stages with different degrees; 3) C. kwangtungensis extract could reduce the levels of serum inflammatory cytokine including interleukin-1β (IL-1β), interleukin-6 (IL-6), tumour necrosis factor-α (TNF-α) of sows at mid-gestation, farrowing and weaning stages with different degrees; 4) C. kwangtungensis extract could significantly increase the beneficial bacterial amounts of Bifidobacterium and Lactobacillus in the sows, and dietary 100 mg/kg and above C. kwangtungensis extract significantly reduced the amount of intestinal Escherichia coli and Clostridium perfringens (P<0.05); 5)by establishing quadratic regression curves, the optimal addition range of C. kwangtungensis extract in the sows was 121-165 mg/kg. In conclusion, the recommended optimal addition range of C. kwangtungensis extract in the sows is 121-165 mg/kg to improve reproductive performance and serum antioxidant level, alleviate postpartum inflammatory reaction, and optimize intestinal flora structure.

广东紫珠提取物对母猪繁殖性能、免疫、抗氧化功能及肠道微生物的影响

选择体质量、胎次和预产期相近的妊娠母猪50头,随机分成5组,每组5个重复,每个重复2头,对照组饲喂基础饲粮,试验组分别饲喂在基础饲粮中添加50、100、150和200 mg/kg广东紫珠提取物的试验饲粮,试验周期从母猪妊娠第30天开始至产后第25天结束,研究饲粮中添加广东紫珠提取物对母猪繁殖性能、免疫和抗氧化性能及肠道微生物的影响。结果表明:1)与对照组相比,50和100 mg/kg组仔猪初生体质量均显著高于对照组(P<0.05),100和150 mg/kg组的仔猪初生窝体质量均显著高于对照组(P<0.05),150 mg/kg组仔猪断奶体质量及断奶窝体质量均显著高于对照组(P<0.05);2)添加广东紫珠提取物可不同程度提高母猪孕中期、分娩时和断奶时血清超氧化物歧化酶活性,降低血清丙二醛含量;3)添加广东紫珠提取物可不同程度降低母猪孕中期、分娩时和断奶时血清白细胞介素1β(interleukin-1β, IL-1β)、白细胞介素6(interleukin-6, IL-6)、肿瘤坏死因子α(tumour necrosis factor-α, TNF-α)等炎症细胞因子水平;4)添加广东紫珠提取物可显著增加母猪肠道乳杆菌属和双歧杆菌属细菌数量,添加100 mg/kg及以上的广东紫珠提取物可降低大肠埃希菌和产气荚膜梭菌数量(P<0.05);5)通过建立二次回归曲线,得出母猪饲粮中广东紫珠提取物最适添加量为121~165 mg/kg。综上所述,母猪饲粮中添加121~165 mg/kg广东紫珠提取物可改善母猪的繁殖性能,提高母猪血清抗氧化水平,缓解母猪产后炎症反应,优化母猪肠道菌群结构。
