“…So, a high concentration of glucose in sheep and newborn lambs treated by maternal organic Mn in this study can be associated with Mn function in gluconeogenesis and insulin secretion. Oral administration of organic Mn (Mn‐glycine) increased the level of glucose in early lactation Holstein cows (Qashqai et al, 2020). In contrast to the results of the present study, feeding Angus cross steers with Mn‐sulfate did not affect plasma glucose convention (Legleiter et al, 2005).…”

“…Hence, the organic forms of Mn in animal feed can be greater widely used due to more absorption and less excretion from the body, as well as less accumulation in the environment (Kišidayová et al, 2018). Oral administration of organic Mn (Mn‐glycine) increased the level of glucose in early lactation Holstein cows (Qashqai et al, 2020). Also, ingestion of the organic form of trace elements (Mn) compared to inorganic in postpartum cows improved the blood total antioxidant status (TAS) (Osorio et al, 2016).…”

It has been documented that adequate maternal manganese (Mn) status is vital for performance and health of ewes and their newborn lambs. However, required level and form of dietary Mn in ruminants are not well defined. The current study was conducted to evaluate the effect of maternal organic Mn supplementation on performance, immunological status, blood biochemical and antioxidant status of Afshari ewes and their newborn lambs in transition period. For this purpose, various organic Mn concentrations were utilized as a supplementary ingredient in formulating the diets of ewes. The ewes were randomly allocated into three groups, fed with 0, and 80 mg/kg organic Mn supplemented diet. At the end of the experiment, the parameters including the performance of newborn lambs, as well as biochemical factors, immune status and antioxidant status in ewes and their newborn lambs were evaluated. The results showed a significant increase in the plasma concentrations of Mn, glucose, insulin, thyroid hormones (T3, T4) and enzymatic antioxidants (SOD, GPX, CAT) in ewes and their newborn lambs that were treated with maternal organic Mn. Moreover, inorganic Mn treatments, the concentration of IgG in newborn lamb's plasma, and colostrum of ewes increased. According to this research, organic Mn acts as a valuable and safe supplementary material that could be exploited for enhancing health of ewes and their newborn lambs.
