This study aimed to evaluate the potential of Moringa oleifera fresh leaves (MOL) as feed supplement on the performance and egg quality of Rhode Island Red (RIR) hens under the tropical conditions of Yucatan, Mexico. Forty-eight RIR hens were allocated in 12 floor pen replicates each with four birds. Thereafter, the replicates were divided into three groups which were corresponded to ad libitum feed (control), ad libitum feed supplemented with MOL T1 (AL + MOL) and restricted feed amount (20% lower than control) with MOL T2 (RCD + MOL), respectively. T1 (AL + MOL) had higher egg laying rate (71.4% versus 66.6%), higher daily egg mass production (45.4 versus 41.9 g/day), lower feed intake (121.3 versus 127.5 g/day) and better feed conversion ratio (2.8 versus 3.2 g feed:g egg) versus control. T2 / (RCD + MOL) had lower values of body weight, egg laying rate, egg weight and egg mass, and recorded better feed conversion ratio than the control group. The control group recorded a higher percentage of pecked eggs versus T1 and T2 (6.5% versus 1.2% and 2.0 %). Similar intake of MOL (3.1 and 3.4 g DM/day) was recorded in T1 (AL + MOL) and T2 (RCD + MOL). Yolk color was improved significantly in T1 (AL + MOL) than both control and T2 (RCD + MOL), while T2 (RCD + MOL) had eggs with lower yolk and higher albumen percentages than the other two ad libitum groups. The results suggest that MOL could be used successfully as sustainable tropical feed resource for RIR hens.
本研究旨在评估辣木鲜叶（MOL）作为饲料添加剂对墨西哥尤卡坦热带条件下罗德岛红鸡（RIR）生产性能和蛋品质的影响。48只RIR母鸡被分配到12个地面围栏重复组中，每组4只。此后，将重复组分为三组，分别对应自由采食饲料（对照组）、添加MOL的自由采食饲料（AL + MOL）和添加MOL的限饲组（比对照组低20%）（RCD + MOL）。与对照组相比，T1（AL + MOL）的产蛋率更高（71.4%对66.6%），每日产蛋量更高（45.4对41.9克/天），采食量更低（121.3对127.5克/天），饲料转化率更好（2.8对3.2克饲料：克鸡蛋）。T2 /（RCD + MOL）的体重、产蛋率、蛋重和蛋产量较低，但其饲料转化率比对照组更好。与T1和T2相比，对照组啄蛋的百分比更高（6.5%对1.2%和2.0%）。T1（AL + MOL）和T2（RCD + MOL）的MOL摄入量相似（分别为3.1和3.4克干物质/天）。T1（AL + MOL）的蛋黄颜色比对照组和T2（RCD + MOL）均有显著改善，而T2（RCD + MOL）的鸡蛋蛋黄比例低于其他两个自由采食组，蛋白比例更高。结果表明，MOL可以成功用作RIR母鸡可持续的热带饲料资源。
