The purpose of the current study was to explore the supplementing effects of leaf powder (MOLP) on plasma and milk biochemical indices and productive/reproductive performance of goats. A total of 30 healthy pregnant goats were randomly distributed ( = 10) into three experimental groups: control (M) group (basal diet without MOLP), M group (basal diet + 2% MOLP), and M group (basal diet + 3.5% MOLP). The experiment started 2 months before parturition and continued till the first month of lactation. The plasma flavonoids were significantly increased in the M group during the entire experiment, whereas the total phenolic contents were enhanced only during the lactation period depending on the supplementation percentage. The amount of vitamin C increased significantly in M and M groups as compared to the M group. Supplementation of MOLP improved the plasma total antioxidant capacity by declining malondialdehyde concentration and total oxidant status values. The activities of superoxide dismutase and peroxidase enzymes were modified in M and M supplemented groups throughout the experiment, while the catalase activity was significantly influenced only during the lactation stage. The protein and lycopene contents in plasma were significantly improved in the M group, whereas the total sugars and carotenoid level was increased in both M and M groups. Dietary supplementation with 3.5% MOLP more effectively enhanced protease and amylase activities as compared to 2% supplementation. MOLP also improved the biochemical indices and antioxidant status of colostrum and milk. The milk yield, weight gain of the kids, and reproductive performance were high in M and M groups in comparison to the M group. These findings disclose that supplementing the diet with 3.5% MOLP improves antioxidant status, milk yield, and reproductive performance in goats.
本研究的目的是探讨叶粉（MOLP）对山羊血浆和乳汁生化指标以及生产/繁殖性能的补充作用。总共30只健康的怀孕山羊被随机分为（每组 = 10只）三个实验组：对照组（M）（基础日粮，不添加MOLP）、M组（基础日粮 + 2% MOLP）和M组（基础日粮 + 3.5% MOLP）。实验在分娩前2个月开始，持续到泌乳的第一个月。在整个实验过程中，M组的血浆类黄酮显著增加，而总酚含量仅在泌乳期根据添加百分比而增加。与M组相比，M组和M组的维生素C含量显著增加。补充MOLP通过降低丙二醛浓度和总氧化剂状态值提高了血浆总抗氧化能力。在整个实验过程中，M组和M补充组的超氧化物歧化酶和过氧化物酶的活性发生了改变，而过氧化氢酶活性仅在泌乳阶段受到显著影响。M组血浆中的蛋白质和番茄红素含量显著提高，而M组和M组的总糖和类胡萝卜素水平均有所增加。与2%的添加量相比，3.5% MOLP的日粮补充更有效地提高了蛋白酶和淀粉酶的活性。MOLP还改善了初乳和乳汁的生化指标和抗氧化状态。与M组相比，M组和M组的产奶量、羔羊体重增加和繁殖性能更高。这些发现表明，在日粮中添加3.5% MOLP可改善山羊的抗氧化状态、产奶量和繁殖性能。
