Microclimate parameters (ammonia, ambient temperature, heat index, and relative humidity) surrounding birds affect the production and health status of poultry. Therefore, this study aimed to evaluate the impact of adding natural zeolite to the litter of Japanese quail on improving microclimate parameters and its reflection in growth performance, blood gases, and blood biochemical parameters. A total of 1152 chicks were obtained from the same hatch at the 20th selection generation. Chicks were allocated into two groups based on the litter composition: Group 1: wheat straw as litter (untreated group); Group 2: 80% wheat straw + 20% zeolite (treated group). Each group consisted of 576 chicks: 410 selected line chicks and 166 control line chicks. Significant and favorable effects of the treatment on microclimate parameters during tested periods were found to favor the treated group. Either the treated group or the selected line had significantly better growth performance than the untreated group and control line. Zeolite-treated quails had significantly desirable blood gases and lower blood acidity and serum total iron binding capacity compared to the untreated group. Thus, adding natural zeolite to the litter enhanced the microclimate parameters that improved growth performance, blood gases, and blood biochemical parameters and reduced ammonia emission.
家禽周围的小气候参数（氨气、环境温度、热指数和相对湿度）会影响家禽的生产和健康状况。因此，本研究旨在评估在日本鹌鹑垫料中添加天然沸石对改善小气候参数的影响及其对生长性能、血气和血液生化参数的反映。从第20代选育的同一孵化场获得了总共1152只雏鸡。根据垫料组成将雏鸡分为两组：第1组：以麦秸作为垫料（未处理组）；第2组：80%麦秸 +
20%沸石（处理组）。每组由576只雏鸡组成：410只选育系雏鸡和166只对照系雏鸡。发现在测试期间处理对小气候参数有显著且有利的影响，有利于处理组。处理组或选育系的生长性能均显著优于未处理组和对照系。与未处理组相比，经沸石处理的鹌鹑具有显著理想的血气、更低的血液酸度和血清总铁结合能力。因此，在垫料中添加天然沸石可增强小气候参数，改善生长性能、血气和血液生化参数，并减少氨气排放。
