【摘要】：本试验旨在研究给妊娠后期和哺乳期母猪补饲发酵芦笋下脚料对母猪和哺乳仔猪血清抗氧化能力、免疫功能和炎性因子含量的影响。选择15头膘情、胎次和预产期相近的妊娠母猪,随机分成3组,每组5个重复,每个重复1头猪。A(对照)、B和C组母猪每头每天分别补饲0、0.25和0.50 kg发酵芦笋下脚料。试验从母猪妊娠期的第85天开始至产后第21天结束。在母猪分娩和仔猪断奶时采集母猪耳静脉血液,在仔猪10和21日龄时采集仔猪前腔静脉血液,分别测定血清指标。结果表明:1)C组母猪在仔猪断奶时血清超氧化物歧化酶(T-SOD)活性极显著高于对照组(P0.01),在母猪分娩和仔猪断奶时血清丙二醛(MDA)含量均极显著低于对照组(P0.01)。B组哺乳仔猪10日龄时血清T-SOD活性显著高于对照组(P0.05),血清MDA含量显著低于对照组(P0.05)。2)C组母猪在母猪分娩时血清生长激素(GH)含量显著高于对照组(P0.05)。3)C组母猪在母猪分娩时血清免疫球蛋白A(IgA)和免疫球蛋白G(IgG)含量显著高于对照组(P0.05)。4)B和C组母猪血清白细胞介素-6(IL-6)含量在母猪分娩和仔猪断奶时均极显著低于对照组(P0.01)。C组母猪在仔猪断奶时血清肿瘤坏死因子-α(TNF-α)含量显著低于对照组(P0.05)。C组哺乳仔猪10日龄时血清TNF-α含量显著低于对照组(P0.05)。综上,每头母猪每天补饲0.50 kg发酵芦笋下脚料可增强其抗氧化能力和免疫功能,提高GH含量,减少炎性反应,同时可提高仔猪的抗氧化能力,减少炎性反应的发生。
[Abstract]:The purpose of this study was to study the effects of supplemental feeding of fermented asparagus waste on serum antioxidant capacity, immune function and inflammatory factor content in sows and suckling piglets. Fifteen pregnant sows were randomly divided into 3 groups, with 5 repeats in each group. Each group was fed with 0.0.25 and 0.50 kg fermented asparagus offal, respectively. The trial began on day 85 of gestation in sows and ended on day 21 of postpartum. The aural vein blood of sows was collected during delivery and weaning, and the blood samples of anterior vena cava of piglets were collected at 10 and 21 days of age, and the serum indexes were measured. The results showed that the activity of serum superoxide dismutase (T-SOD) in group C during weaning was significantly higher than that in control group (P0.01), and the level of serum malondialdehyde (MDA) in sows during delivery and weaning was significantly lower than that in group B (P0.01). Serum T-SOD activity was significantly higher than that of control group (P0.05), serum MDA content was significantly lower than that of control group (P0.05). Serum growth hormone (GH) content in group C was significantly higher than that in control group (P0.05). The levels of white A (IgA) and immunoglobulin G (IgG) were significantly higher in group B and C than those in the control group (P0.05). The levels of serum interleukin-6 (IL-6) in sows during delivery and weaning were significantly lower than those in the control group (P0.01) .C groups were significantly lower than those in the control group (P0.01). The content of factor 伪 (TNF- 伪) was significantly lower than that of the control group (P0.05). The serum TNF- 伪 content of the lactation piglets in group C was significantly lower than that in the control group at the age of 10 days (P0.05). In conclusion, the supplementation of 0.50 kg fermented asparagus waste material per day could enhance the antioxidant ability and immune function, increase the content of GH, reduce inflammatory reaction, and increase the antioxidant ability of piglets and reduce the occurrence of inflammatory reaction.
