Effects of pawpaw leaf and seed meals composite mix (PCM) supplementation on broiler chickens were assessed. A total of 396-day-old Arbor Acres broiler chicks were distributed to six diets: 1 = 0 g/kg PCM; 2 = 2 g/kg PCM; 3 = 4 g/kg PCM; 4 = 6 g/kg PCM; 5 = 8 g/kg PCM; and 6 = 10 g/kg PCM. Body weight gain and feed conversion ratio of the birds fed diet 5 was similar to those fed diets 4 and 6 but better than ( P < 0.05) those fed diets 1, 2 and 3 at grower phase and overall period of the feeding trial. Alanine aminotransferase (ALT) concentration decreased in the birds with an increase in the dietary PCM supplementation level such that ALT concentration reduction ( P < 0.05) was recorded in the birds fed diets 5 and 6 when compared to those fed diet 1. The serum cholesterol in birds fed diets 3, 4, 5 and 6 was similar to the level recorded for birds fed diet 2 but lower ( P < 0.05) than the level in birds fed the control diet. The superoxide dismutase and glutathione peroxidase serum concentration improved ( P < 0.05) in the birds fed PCM-supplemented diets (2 to 6) compared to those fed diet 1. Catalase serum concentration in birds fed diet 5 was similar to those fed diets 3, 4 and 6 but higher ( P < 0.05) than the concentration in birds fed diets 1 and 2. The PCM dietary supplementations (6 g/kg to 10 g/kg) did not affect on the performance and health status of the broiler chickens negatively.

木瓜叶和籽粕复合混合膳食补充剂：对肉鸡生产性能、盲肠微生物群和血液分析的影响

评估了添加木瓜叶和种子粉复合混合物 (PCM) 对肉鸡的影响。总共 396 天大的 Arbor Acres 肉鸡被分配到六种日粮中：1 = 0 g/kg PCM；2 = 2 g/kg PCM；3 = 4 g/kg PCM；4 = 6 g/kg PCM；5 = 8 g/kg PCM；和 6 = 10 g/kg PCM。饲喂日粮 5 的鸡群的体重增加和饲料转化率与饲喂日粮 4 和 6 的鸡群相似，但在生长阶段和饲喂试验的整个时期优于饲喂日粮 1、2 和 3 的鸡群（ P < 0.05）。随着日粮 PCM 补充水平的增加，鸡的丙氨酸转氨酶 (ALT) 浓度降低，因此与饲喂日粮 1 的鸡相比，饲喂日粮 5 和 6 的鸡的 ALT 浓度降低 ( P < 0.05)。在饲喂日粮 3、4、5 和 6 与饲喂日粮 2 的鸡只记录的水平相似，但低于饲喂对照日粮的鸡只的水平（ P < 0.05）。与饲喂日粮 1 的鸡相比，饲喂 PCM 补充日粮（2 至 6）的鸡的超氧化物歧化酶和谷胱甘肽过氧化物酶血清浓度提高（ P < 0.05）。饲喂日粮 5 的鸡的过氧化氢酶血清浓度与饲喂 3 的鸡相似， 4 和 6 但高于 ( P < 0.05) 饲喂日粮 1 和 2 的鸡只的浓度。 PCM 日粮补充剂（6 g/kg 至 10 g/kg）对肉鸡的生产性能和健康状况没有负面影响.
