Abstract

The plants originated from an agroforestry system have gained immense importance in livestock health and production. The trial was planned to examine the effects of Moringa oleifera leaf extract (MLE) supplementation on the performance, blood metabolites, immunity and lipid peroxidation in broiler chicks. A total of 350 day old broiler chicks were divided into negative control (MLE₀), positive control (antibiotic; AB-enro), M. oleifera supplementation at the concentration of 60 (MLE₆₀), 90 (MLE₉₀) and 120 mL/L (MLE₁₂₀) of drinking water. Performance parameters such as feed intake, body weight and feed conversion ratio, antibody titer against Newcastle disease and infectious bronchitis, heterophils and lymphocytes ratio, blood glucose, protein, and malanodialdehyde were determined. The results showed that carcass yield was significantly (p < 0.05) higher in MLE₉₀ followed by MLE₁₂₀ and AB-enro. MLE₆₀ and MLE₉₀ showed significant (p < 0.05) increase in antibody titer against New-castle (ND) and Infectious-bronchitis (IB) respectively. Significantly (p < 0.05) lower Heterophil to lymphocyte (H:L) ratio was observed in MLE₉₀ and MLE₁₂₀ compared to the negative control. Significantly (p < 0.05) lower blood glucose concentration and significantly (p < 0.05) higher mean serum protein value were found in MLE₁₂₀. The MLE₁₂₀ showed significantly (p < 0.05) lower concentration of malanodialdehyde (MDA). It was concluded that M. oleifera leaf extract supplementation at the concentration of 120 mL/L of drinking water improved carcass yield, immunity, blood metabolites and reduced lipid peroxidation in broiler chicks.

• Highlights

• Moringa improved the carcass yield of broiler

• Moringa is an excellent immune potentiating agent in broiler

• Moringa enhanced the antioxidant potential of broiler

摘要

源自农林系统的植物在牲畜健康和生产方面具有巨大的重要性。该试验计划检查补充辣木叶提取物 (MLE) 对肉鸡生产性能、血液代谢物、免疫力和脂质过氧化作用的影响。将总共​​ 350 日龄的肉鸡分为阴性对照 (MLE ₀ )、阳性对照 (抗生素；AB-enro)，添加浓度为 60 (MLE ₆₀ )、90 (MLE ₉₀ ) 和 120 mL的M. oleifera /大号 (MLE ₁₂₀) 的饮用水。测定了诸如采食量、体重和饲料转化率、新城疫和传染性支气管炎抗体滴度、异嗜细胞和淋巴细胞比率、血糖、蛋白质和丙二醛等性能参数。结果表明， MLE _{90的胴体产量显着 (} p  < 0.05) 更高，其次是 MLE ₁₂₀和 AB-enro。MLE ₆₀和 MLE ₉₀分别显示针对新城疫 (ND) 和传染性支气管炎 (IB) 的抗体效价显着 ( p  < 0.05) 增加。_{在 MLE 90}和 MLE ₁₂₀中观察到显着 ( p  < 0.05) 较低的嗜异粒细胞与淋巴细胞 (H:L) 比率与阴性对照相比。_{在 MLE 120}中发现显着 ( p  < 0.05) 较低的血糖浓度和显着 ( p  < 0.05) 较高的平均血清蛋白值。MLE ₁₂₀显示显着 ( p  < 0.05) 较低的丙二醛 (MDA) 浓度。得出的结论是，在饮用水中添加浓度为 120 mL/L 的M. oleifera叶提取物可提高肉鸡的胴体产量、免疫力、血液代谢物并减少脂质过氧化。

• 强调

• 辣木提高肉鸡胴体产量

• 辣木是肉鸡优良的免疫增强剂

• 辣木提高肉鸡的抗氧化潜力
