Pharmacological and nutritional benefits of plant leaf extracts can be harnessed to address the problem of poor chick quality, performance and high mortality, which affect both hatchery and farm managers. This study sought to evaluate the effect of Soursop leaf extract (SLE) on the hatching and post-hatch performance of Noiler chicks. A total of 640 fertile eggs were randomly distributed into four groups of five replicates: (0.25 µg SLE), (0.5 µg SLE), (0.75 µg SLE) and a non-injected control. On day 18 of incubation, 0.2 ml of SLE was injected into the airspace of the eggs. At hatch, embryonic mortality, hatchability, and chick quality were evaluated. Hatched chicks were reared to assess feed intake, weight gain, feed conversion ratio (FCR) and mortality. Results showed no significant difference ( > 0.05) in embryonic mortality, hatchability and weight gain among the treatment groups. Chick weight and feed intake were significantly higher ( < 0.05) in SLE groups, while FCR and mortality were significantly lower ( < 0.05) in SLE groups. It was concluded that injection of SLE improved chick weights, feed conversion and livability of Noiler chicks.
植物叶提取物的药理和营养益处可用于解决雏鸡质量差、生长性能不佳和死亡率高的问题，这些问题影响着孵化场和养殖场管理人员。本研究旨在评估刺果番荔枝叶提取物（SLE）对诺伊勒雏鸡孵化及孵化后生长性能的影响。总共640枚受精蛋被随机分为四组，每组五个重复：（0.25微克SLE）、（0.5微克SLE）、（0.75微克SLE）和一个未注射的对照组。在孵化第18天，向蛋的气室中注射0.2毫升SLE。孵化时，评估胚胎死亡率、孵化率和雏鸡质量。对孵出的雏鸡进行饲养，以评估采食量、体重增加、饲料转化率（FCR）和死亡率。结果显示，各处理组之间在胚胎死亡率、孵化率和体重增加方面无显著差异（>0.05）。SLE组的雏鸡体重和采食量显著更高（<0.05），而SLE组的FCR和死亡率显著更低（<0.05）。得出的结论是，注射SLE可提高诺伊勒雏鸡的体重、饲料转化率和存活率。
