B vitamins improve animal performance through promote a wide range of metabolic pathways in animals as cofactors. Therefore, the impact of B-complex vitamin injection on performance, metabolic diseases, hematological parameters, and antioxidant status in pregnant Sannen goats and their newborn kids during the transition period was investigated. The pregnant goats (3 years old) were randomly divided into two groups: control (No B complex vitamins injection) and B complex vitamins (5 ml B complex vitamins injection per animal). B complex vitamins were injected twice intramuscularly into goats, according to the manufacturer's recommendation, during five- and three-weeks prior kidding. To determine the dry matter intake, feed samples were prepared. Also, metabolic diseases in goats and their offspring were recorded during the study. Blood samples of goats and newborn kids were taken seven days after parturition and measured for B vitamins concentrations, as well as hematological and antioxidant parameters. According to the results, the performance (body weight and dry matter intake) of goats and kids improved in B-complex vitamins group compared to the control group (P < 0.05). In addition, metabolic diseases were reduced in the goats and their offspring treated with B complex vitamins compared to the control group during the transition period (P < 0.05). The levels of cobalamin, pyridoxine, thiamine, folic acid, nicotinic, pantothenic, and unconjugated pteridine increased in the plasma of goats and their children by maternal B complex injection than in the control group during the transition period (P < 0.05). Higher (P < 0.05) levels of red blood cells, hemoglobin, hematocrit, total antioxidant status, glutathione peroxidase, superoxide dismutase, and catalase in goats' plasma, as well as red blood cells, hemoglobin, hematocrit, glutathione peroxidase, and superoxide dismutase in kids' plasma treated with B complex vitamins than the control group, were observed (P < 0.05). These results suggest that maternal Bcomplex vitamin injection is required for the improvement of performance, hematological status, and antioxidant status in pregnant goats and their kids.
B 族维生素作为辅助因子，通过促进动物体内广泛的代谢途径来提高动物的性能。因此，本研究旨在调查围产期 Sannen 妊娠母羊及其新生羔羊注射 B 族复合维生素对性能、代谢疾病、血液参数和抗氧化状态的影响。将 3 岁的妊娠母羊（n=30）随机分为两组：对照组（未注射 B 族复合维生素）和 B 族复合维生素组（每只动物注射 5ml B 族复合维生素）。根据制造商的建议，在分娩前 5 周和 3 周时，B 族复合维生素通过肌肉内注射两次给予母羊。为了确定干物质摄入量，准备了饲料样本。此外，在研究期间还记录了母羊及其后代的代谢疾病。分娩后 7 天，采集母羊和新生羔羊的血液样本，测量 B 族维生素浓度以及血液学和抗氧化参数。结果表明，与对照组相比，B 族复合维生素组母羊及其羔羊的性能（体重和干物质摄入量）有所提高（P<0.05）。此外，与对照组相比，在围产期接受 B 族复合维生素治疗的母羊及其后代的代谢疾病减少（P<0.05）。与对照组相比，母羊及其后代血浆中的钴胺素、吡哆醇、硫胺素、叶酸、烟酸、泛酸和未结合蝶呤水平在围产期通过母源 B 族复合注射增加（P<0.05）。与对照组相比，B 族复合维生素组母羊血浆中的红细胞（RBC）、血红蛋白（Hb）、红细胞压积（Hct）、总抗氧化状态（TAS）、谷胱甘肽过氧化物酶（GSH-Px）、超氧化物歧化酶（SOD）和过氧化氢酶（CAT）以及羔羊血浆中的 RBC、Hb、Hct、GSH-Px 和 SOD 水平较高（P<0.05）。这些结果表明，母羊注射 B 族复合维生素对于提高妊娠母羊及其羔羊的性能、血液学状态和抗氧化状态是必需的。
