Minerals is required small amounts among various nutrients, but it has a significant impact on sow longevity and reproduction performance. This study was carried out to see the beneficial effects of marine-derived Ca-Mg complex on the reproductive performance of sows during four-parity periods. Seventy-two gilts ([Yorkshire × Landrace] × Duroc), with an average body weight of 181 kg, were randomly allocated to three groups; CON (basal diet), 0.3LC (CON - MgO - 0.3% limestone + 0.4% Ca-Mg complex), and 0.7LC (CON - MgO - 0.7% limestone + 0.4% Ca-Mg complex). During parity 3 and 4, the expression level of SCD gene was lower in the umbilical cord of piglets born to 0.3LC and 0.7LC sows compared with the CON sows. During parity 2, 3 and 4, and gene expressions were higher in the umbilical cord of piglets born to 0.7LC sows and the placenta of sows from 0.3LC groups, respectively. Ca-Mg complex increased ( < 0.05) Ca and Mg concentrations in sows and their piglets' serum as well as in colostrum regardless of parities. The serum vitamin D concentration was higher ( < 0.05) in their first parity, whereas serum prolactin and estrogen concentrations were higher ( < 0.05) during the fourth and third parity, respectively. The growth hormone concentrations were higher ( < 0.05) in the piglets born to sows during the first and second parity. The fat and immunoglobulin A (IgA) concentrations in colostrum were higher ( < 0.05) during the third and fourth parity, respectively. A reduction ( < 0.05) in salivary cortisol, epinephrine, and norepinephrine concentrations was observed in 0.3LC and 0.7LC sow groups compared with CON after farrowing regardless of parity, however before farrowing, a reduction in norepinephrine was observed. Before farrowing, the epinephrine and norepinephrine concentrations were higher ( < 0.05) during the first and second parity. After farrowing, the concentration of these hormones was higher during the second parity. Taken together, sows' parity and dietary Ca-Mg complex supplementation influenced serum metabolites, colostrum nutrients, stress hormones as well as the gene expressions related to lipid and glucose metabolism.
矿物质在各种营养素中需求量较少，但对母猪的使用年限和繁殖性能有显著影响。本研究旨在观察海洋来源的钙镁复合物在母猪四个繁殖周期对其繁殖性能的有益作用。72头平均体重181千克的后备母猪（[约克夏×长白]×杜洛克）被随机分为三组；对照组（基础日粮）、0.3LC组（对照组-氧化镁-0.3%石灰石+0.4%钙镁复合物）和0.7LC组（对照组-氧化镁-0.7%石灰石+0.4%钙镁复合物）。在第3和第4胎次期间，与对照组母猪所产仔猪脐带相比，0.3LC组和0.7LC组母猪所产仔猪脐带中SCD基因的表达水平较低。在第2、3和第4胎次期间，0.7LC组母猪所产仔猪脐带和0.3LC组母猪胎盘的 和 基因表达分别较高。无论胎次如何，钙镁复合物均可提高（<0.05）母猪及其仔猪血清以及初乳中的钙和镁浓度。在第一胎次时，其血清维生素D浓度较高（<0.05），而在第四和第三胎次期间，血清催乳素和雌激素浓度分别较高（<0.05）。在第一和第二胎次期间，母猪所产仔猪的生长激素浓度较高（<0.05）。初乳中的脂肪和免疫球蛋白A（IgA）浓度在第三和第四胎次期间分别较高（<0.05）。无论胎次如何，与对照组相比，在分娩后0.3LC组和0.7LC组母猪唾液中皮质醇、肾上腺素和去甲肾上腺素浓度均降低（<0.05），但在分娩前，观察到去甲肾上腺素浓度降低。在分娩前，第一和第二胎次期间肾上腺素和去甲肾上腺素浓度较高（<0.05）。分娩后，这些激素的浓度在第二胎次期间较高。综上所述，母猪的胎次和日粮中补充钙镁复合物会影响血清代谢物、初乳营养成分、应激激素以及与脂质和葡萄糖代谢相关的基因表达。
