This experiment determined the effects of Propolis (PRO) and Spirulina platensis (SP) powder on Japanese quail growth performance, nutrient digestibility, and certain serum parameters under heat stress condition. A total of two hundred unsexed Japanese quails (seven days old) were randomly assigned to four treatments. Each treatment included five replicates (10 quails per each). For five weeks, quail chicks were fed basal diet without supplementation (control), quail chicks were fed basal diet supplemented with 400 mg/kg of PRO, quail chicks were fed basal diet supplemented with 1 g/kg of Spirulina platensis powder (SP), and quail chicks were fed basal diet supplemented with same amount of propolis and Spirulina platensis powder (Mix). Data analysis revealed that supplementation of PRO at 400 mg/kg to quails diet greatly improved (P = 0.001) body weight, body weight gain, feed conversion ratio (FCR) as well as improved ether extract, crude protein digestibility (P = 0.028), serum concentration of albumin, serum total cholesterol in addition to reduced (P < 0.001) the count of Bacillus SPP, Escherichia coli (E. coli), Clostridium Spp, and Enterococcus Spp under heat stress condition. Dietary inclusion of SP at a dose of 1 g/kg alone or in combination with PRO significantly (P = 0.001) improved FCR, serum concentration of albumin in addition to reduced digestibility of ether extract and serum concentration of triglyceride (P = 0.001) compared to the control group. In conclusion, when used individually, propolis (400 mg/kg) and Spirulina (1 g/kg) improved performance and health status of Japanese quails under heat stress; however, their combination did not yield additive benefits.
本实验测定了蜂胶（PRO）和钝顶螺旋藻（SP）粉对热应激条件下日本鹌鹑生长性能、养分消化率及某些血清参数的影响。总共200只未分性别的7日龄日本鹌鹑被随机分为4组处理。每组处理包含5个重复（每组10只鹌鹑）。在为期5周的时间里，鹌鹑雏鸡被喂食不添加任何物质的基础日粮（对照组）、添加400 mg/kg PRO的基础日粮、添加1 g/kg钝顶螺旋藻粉（SP）的基础日粮，以及添加等量蜂胶和钝顶螺旋藻粉的基础日粮（混合组）。数据分析显示，在鹌鹑日粮中添加400 mg/kg的PRO可显著提高（P = 0.001）体重、体重增加、饲料转化率（FCR），同时提高乙醚提取物、粗蛋白消化率（P = 0.028）、血清白蛋白浓度、血清总胆固醇，此外还能降低（P < 0.001）热应激条件下芽孢杆菌属、大肠杆菌、梭菌属和肠球菌属的数量。与对照组相比，单独添加1 g/kg剂量的SP或与PRO联合添加，均可显著（P = 0.001）提高FCR、血清白蛋白浓度，同时降低乙醚提取物消化率和血清甘油三酯浓度（P = 0.001）。总之，单独使用时，蜂胶（400 mg/kg）和螺旋藻（1 g/kg）可改善热应激条件下日本鹌鹑的生产性能和健康状况；然而，它们的组合并未产生相加效益。
