It is proven that B vitamins through promote a wide range of metabolic pathways in animals as cofactors improve animal performance.
This study was conducted to investigate the impacts of maternal B complex vitamin injection on performance and plasma parameters in goats and their offspring, as well as the faeces status of newborn kids.
In this research, the pregnant goats (3 years old) were randomly divided into two groups: the control group (without B complex vitamin injection) and the B complex vitamin group (5 mL B complex vitamin injection per animal). The animals were injected with 5 mL B complex vitamin twice during the transition period (5 weeks pre- and 5 weeks post-kidding). The goats during the transition period and kids on days 10, 20 and 30 were weighed. Feed intake by goats and consumption of milk and starter in kids were recorded daily. The dry matter digestibility by kids was tested by collecting samples of faeces and feed for 5 days in the last week. Chemical analysis was determined using the AOAC method. The kids' faeces were prepared daily during the study. The blood samples of goats and newborn kids were taken 7 days after kidding. Then, levels of B group vitamin, as well as concentrations of liver enzymes, thyroid hormones and immunological parameters, were determined in plasma of goat and their offspring. In addition, concentrations of glucose and insulin were measured in goat plasma (Asadi et al., 2024).
According to results, the performances of goats and their offspring, as well as kids' faeces status, were improved by maternal B complex vitamin injection (p < 0.0001). The levels of cobalamin, pyridoxine, thiamine, folic acid, nicotinic, pantothenic and unconjugated pteridine increased in the plasma of goats and their kids in the B complex vitamin group compared with the control group during the transition period (p < 0.0001). Injection of maternal B complex vitamin raised the plasma levels of triiodothyronine and tetraiodothyronine, immunoglobulin G and immunoglobulin M in goats and their offspring (p < 0.0001). Higher levels of glucose and lower levels of insulin were determined in the goats injected with B complex vitamin (p < 0.0001).
These results suggest that maternal B complex vitamin injection is required for the improvement of performance, health status and the blood plasma parameters in pregnant goats and their kids.
研究证明，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生产性能。
本研究旨在探讨母羊 B 族复合维生素注射对山羊及其后代的生产性能和血浆参数以及新生羔羊粪便状况的影响。
本研究中，将 3 岁的妊娠母羊随机分为两组：对照组（不注射 B 族复合维生素）和 B 族复合维生素组（每只动物注射 5 mL B 族复合维生素）。在过渡阶段（产羔前 5 周和产羔后 5 周），动物被注射 5 mL B 族复合维生素两次。在过渡阶段和第 10、20 和 30 天对山羊进行称重。每天记录山羊的采食量以及羔羊的奶和开食料消耗量。在最后一周的 5 天内通过收集粪便和饲料样品来测定羔羊的干物质消化率。使用 AOAC 方法进行化学分析。在研究期间，每天准备羔羊的粪便。在产羔后 7 天，采集母羊和新生羔羊的血液样本。然后，测定母羊及其后代血浆中 B 族维生素水平以及肝酶、甲状腺激素和免疫参数浓度。此外，还测定了母羊血浆中的葡萄糖和胰岛素浓度（Asadi 等人，2024）。
结果表明，母羊 B 族复合维生素注射可改善母羊及其后代的生产性能以及羔羊的粪便状况（p<0.0001）。与对照组相比，在过渡阶段，B 族复合维生素组母羊及其羔羊的血浆中钴胺素、吡哆醇、硫胺素、叶酸、烟酸、泛酸和未结合蝶呤的水平升高（p<0.0001）。母羊 B 族复合维生素注射可提高母羊及其后代的血浆三碘甲状腺原氨酸和甲状腺素、免疫球蛋白 G 和免疫球蛋白 M 水平（p<0.0001）。注射 B 族复合维生素的母羊血糖水平升高，胰岛素水平降低（p<0.0001）。
这些结果表明，母羊 B 族复合维生素注射对于提高妊娠母羊及其羔羊的生产性能、健康状况和血浆参数是必需的。
