Effect of exogenous melatonin on performance and mastitis in dairy cows raw data

We believe that our study makes a significant contribution to the literature because we found that the somatic cell count of the cows in the trialgroup showed significant reduction in different periods of time, in terms of production performance, the cows in the T120 group during melatonin feeding significantly increased milk milk fat percentage, milk fat yield, milk protein percentage and milk protein yield, respectively. In terms of serum biochemical indices, the cows in the T120 group during melatonin feeding had significant effects on total protein, albumin and globulin content. In addition, melatonin had a significant effect on cows in terms of antioxidant capacity and anti-inflammatory capacity. Finally, exogenous melatonin had a positive effect on blood melatonin levels in dairy cows.Further, we believe that this paper will be of interest to the readership of your journal because our results demonstrate thatsupplementationof exogenous melatonin to dairy cattle rations reduces milk somatic cell count and improves milk quality, cow antioxidant capacity, anti-inflammatory capacity, and blood melatonin content. Our findings will be insightful for farming and agriculture experts as they provide new insights for the healthy breeding of ruminants.

本研究认为其对现有畜牧科研文献具有重要贡献：本研究发现，试验组奶牛的体细胞计数在不同时间节点均呈现显著下降趋势。就生产性能而言，饲喂褪黑素（melatonin）的T120组奶牛的乳脂率、乳脂产量、乳蛋白率及乳蛋白产量均显著提升。就血清生化指标而言，饲喂褪黑素的T120组奶牛的总蛋白、白蛋白及球蛋白含量均受到显著影响。此外，褪黑素对奶牛的抗氧化能力与抗炎能力均具有显著作用。最后，外源褪黑素对奶牛血液褪黑素水平具有积极影响。进一步而言，本研究认为本文将受到贵刊读者的广泛关注，因为研究结果表明，在奶牛日粮中添加外源褪黑素可降低牛乳体细胞计数，并改善乳品质、奶牛抗氧化能力、抗炎能力及血液褪黑素含量。本研究结果可为畜牧农业领域专家提供重要参考，为反刍动物的健康养殖提供全新视角。
