摘要
旨在研究饲粮中添加金荞麦茎叶粉(GBSLM)对赣南藏香猪初产母猪养分表观消化率、血清生化指标及粪微生物区系的影响。选取健康且体况和预产期相近的初产妊娠赣南藏香母猪18头,随机分为3组,每组6个重复,每个重复1头猪。对照组(CON组)饲喂基础饲粮,试验组(T1和T2组)分别饲喂在基础饲粮中添加10%和20%GBSLM的试验饲粮。试验自妊娠第70天开始至分娩后第28天结束。结果显示:1)与CON组相比,在母猪妊娠第105天,T1和T2组的总能和干物质表观消化率显著提高(P<0.05),T1组的粗脂肪和磷表观消化率显著提高(P<0.05),T2组的粗蛋白质表观消化率显著降低(P<0.05),在母猪分娩后第15天,T2组的总能、干物质、粗脂肪和粗灰分表观消化率显著高于对照组(P<0.05)。2)与CON组相比,T1和T2组母猪妊娠第105天的血清总蛋白含量显著提高(P<0.05),血清葡萄糖含量显著降低(P<0.05)。3)厚壁菌门、拟杆菌门和螺旋菌门是3个组共有的优势菌门。T1和T2组母猪妊娠第105天的粪中拟杆菌门相对丰度显著高于CON组(P<0.05),厚壁菌门相对丰度低于CON组,但差异不显著(P>0.05)。T2组母猪分娩后第15天粪中放线菌门相对丰度显著低于CON组(P<0.05)。链球菌属、狭义梭菌属1和土芽孢杆菌属是3个组共有的优势菌属。T1和T2组母猪妊娠第105天的粪中UCG-005菌属、理研菌科RC9肠道群属和普雷沃氏菌科_NK3B31群菌属的相对丰度均显著高于CON组(P<0.05),链球菌属的相对丰度显著低于CON组(P<0.05)。综上所述,饲粮中添加金荞麦茎叶粉可提高母猪总能、干物质、粗脂肪、磷和粗灰分养分表观消化率和血清TP含量,调节菌群丰富度和多样性。在本试验条件下,金荞麦茎叶粉可运用到赣南藏香母猪饲粮中,添加量以10%效果最优。
This experiment was conducted to evaluate the effects of golden buckwheat stem and leaf meal(GBSLM)supplementation in Gannan Tibetan primiparous sows diet by determining nutrient apparent digestibility,serum biochemical indices and fecal microflora composition.Eighteen healthy pregnant primiparous Gannan Tibetan sows with similar body condition and expected delivery date were randomly allocated to 3 groups with 6 replicates in per group and 1 pig in per replicate.Pigs in the control group(CON group)were fed only the basal diet,while the other groups(T1 and T2 groups)were fed the basal diets supplemented with 10%and 20%GBSLM,respectively.The trial period was from day 70 of gestation to 28 day after delivery.The results showed that:1)Compared with the CON group,the apparent digestibility of gross energy(GE)and dry matter(DM)of sows at 105 day of gestation in T1 and T2 groups were significantly increased(P<0.05),ether extract(EE)and phorsphorous in T1 group increased significantly(P<0.05),while the apparent digestibility of crude protein(CP)in T2 group was pronouncedly decreased(P<0.05).At 15 day after delivery,sows in T2 group had significantly higher apparent digestibility of GE,DM,EE and Ash than those of the CON group(P<0.05).2)In comparison to the CON group,the T1 and T2 groups dramatically heighted the TP content(P<0.05)and lowered the GLU content(P<0.05)in serum of sows after day 105 of gestation.3)Firmicutes,Bacteroidota and Spirochaetota were the dominant bacteria phyla shared by the three groups.On the 105th day of pregnancy,the relative abundance of Bacteroidota in feces of sows in T1 and T2 groups were markedly higher than that in CON group(P<0.05).Although the relative abundance of Firmicutes were lower in the T1 and T2 groups compared to the CON group,no significant effects were observed(P>0.05).Furthermore,contrasted with the CON group,the T2 group statistically diminished the relative abundance of Actinobacteria in feces of sows at day 15 after parturition(P<0.05).Streptococcus,Clostridium_sensu_stricto_1 and Terrisporobacter were the dominant genera shared by the three groups.Moreover,on the 105th day of pregnancy,the T1 and T2 groups had an apparently higher fecal UCG-005,Rikenellaceae_RC9_gut_group and Prevotellaceae_NK3B31_group relative abundance(P<0.05)and an obviously lower fecal Streptococcus relative abundance compared to the CON group(P<0.05).In conclusion,diets supplemented with golden buckwheat stem and leaf meal GBSLM are conducive to elevating the apparent nutrients digestibility of GE,DM,EE,P and Ash,increasing the serum level of TP,regulating the richness and diversity of intestinal flora in Gannan Tibetan sows.Under the conditions of this experiment,golden buckwheat stem and leaf meal GBSLM can be used in the diet of Gannan Tibetan sows and the addition of 10%golden buckwheat stem and leaf meal GBSLM is the optimal dose.
