本研究旨在评估洋甘菊精油在提高生产和生殖性能方面的有益作用。鸡蛋质量,和血液代谢产物,并减少鹌鹑饲养者日粮中曲霉毒素A(OTA)的毒性作用。总共144只成熟的鹌鹑,8周老,分为6组。治疗方法为:G1(对照),G2(补充OTA1mg/kg饮食),G3(补充洋甘菊油0.5g/kg饮食),G4(补充洋甘菊油1克/公斤饮食),G5(补充OTA1mg/kg饮食+洋甘菊油0.5g/kg饮食),和G6(补充OTA1mg/kg饮食+洋甘菊油1g/kg饮食)。单独施用OTA显著降低鹌鹑饲养员的产蛋量和质量(P<0.0001)。此外,饲料转化率(FCR)差,生育率(P<0.0001),记录孵化率(P<0.0009)。OTA污染组的血清蛋白(总蛋白和球蛋白)水平也有显著下降(P<0.05),随着血清肝酶水平升高,如丙氨酸转氨酶(ALT)和天冬氨酸转氨酶(AST),肾功能测试为尿素和肌酐水平(P<0.05)。曲霉毒素A污染的饲料导致总胆固醇(TC)显著升高(P<0.05),甘油三酯(TG),低密度脂蛋白(LDL),和极低密度脂蛋白(VLDL),抗氧化状态和免疫反应显著降低(P<0.05)。洋甘菊精油的补充,0.5g/kg或1g/kg,基础日粮或补充OTA的饲料,显示孵化率显著增加,生育力,鸡蛋质量,产蛋量和更好的FCR,鸡蛋质量,与仅OTA相比时的免疫状态。此外,洋甘菊精油补充剂可改善肝肾功能标志物,降低LDL,VLDL),TG,和TC。随着谷胱甘肽过氧化物酶(GPX)抗氧化状态的显著增加(P<0.05),总抗氧化能力(TAC),超氧化物歧化酶(SOD)和显著(P<0.05)提高免疫应答,IgG,溶菌酶和补体3.总之,洋甘菊油补充,单独或与OTA组合,减少了OTA的不利影响,提高了生产和繁殖性能,鸡蛋质量,和日本鹌鹑饲养员的血液代谢产物.
This study aimed to evaluate the beneficial role of
chamomile essential oil in improving productive and reproductive performances, egg quality, and blood metabolites and reducing the toxic effect of Ochratoxin A (OTA) in quail breeder\'s diets. A total of 144 mature quails, 8 wk old, were divided into 6 groups. The treatments were: G1 (the control), G2 (supplemented with OTA 1 mg/kg diet), G3 (supplemented with chamomile oil 0.5 g/kg diet), G4 (supplemented with
chamomile oil 1 G/kg diet), G5 (supplemented with OTA 1 mg/kg diet +
chamomile oil 0.5 g/kg diet), and G6 (supplemented with OTA 1 mg/kg diet +
chamomile oil 1 g/kg diet). The OTA administration alone significantly decreased egg production and mass in quail breeders (P < 0.0001). Moreover, poor feed conversion ratio (FCR), fertility percentage (P < 0.0001), and hatchability percentage (P < 0.0009) were recorded. A significant decline (P < 0.05) in the levels of serum protein (total protein and globulin) was also recorded in OTA-contaminated groups, along with elevated serum levels of liver enzymes such as alanine transaminase (ALT) and Aspartate transaminase (AST) and kidney function test as urea and creatinine levels (P < 0.05). Ochratoxin A-contaminated feed resulted in a significant elevation (P < 0.05) in total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL), along with a significant reduction (P < 0.05) in antioxidant status and immunological response. The supplementation of chamomile essential oil, either 0.5 g/kg or 1g/kg, to the basal diet or OTA-supplemented feed, revealed a significant increase in hatchability %, fertility, egg mass, and egg production and better FCR, egg quality, and immunological status when compared to OTA only. Moreover,
chamomile essential oil supplementation improves liver and kidney function markers, decreases LDL, VLDL), TG, and TC. Along with a significant increase (P < 0.05) in terms of antioxidant status as glutathione peroxidase enzyme (GPX), total antioxidant capacity (TAC), and superoxide dismutase (SOD) and significantly (P < 0.05) improves immunological response as IgM, IgG, lysozyme and complement 3. In summary,
chamomile oil supplementation, either separate or combined with OTA, reduced the adverse effects of OTA and led to improved productive and reproductive performance, egg quality, and blood metabolites in Japanese quail breeders.
