Broiler behavior is closely related to the breeding environment. Therefore, studying broiler behavior helps breeding farm workers to better carry out welfare breeding. In the breeding environment of yellow feather broilers, temperature, humidity, and ammonia concentration are the main factors that affect the behavior of the broilers. This study used a multichromatic aberration model to process the color images of yellow feather broilers to extract the activity feature of the broilers at different periods, utilized the Cb component of YCbCr color model and the b component of Lab color model to remove background litter in images, and employed the Q component of YIQ color model to remove the feeders and the drinkers from the image. The segmented images were constructed into an accumulator to generate a heat map of yellow feather broilers’ activity. Then, the correlation between the activity and the temperature and humidity index (THI) and the correlation between the activity and ammonia concentration were explored. The experiment found that the activity of the broilers was significantly positively correlated with ammonia concentration (), indicating that the activity of yellow feather broilers increased with ammonia concentration ascending. Besides, the THI in the broiler chamber had a significant positive correlation with the ammonia data (), indicating that when the THI in the broiler chamber increases, the ammonia concentration rises. The research provides a direction for exploring the impact of THI and ammonia concentration on the performance of yellow feather broilers. At the same time, it provides a theoretical basis for the early warning and judgment of broiler breeding by farm workers in the future.

基于多色像差模型的黄羽肉鸡养殖环境与活动相关性研究

肉鸡行为与养殖环境密切相关。因此，研究肉鸡行为有助于养殖场工人更好地开展福利养殖。在黄羽肉鸡的养殖环境中，温度、湿度和氨浓度是影响肉鸡行为的主要因素。本研究采用多色差模型对黄羽肉鸡的彩色图像进行处理，提取不同时期肉鸡的活动特征，利用YCbCr颜色模型的Cb分量和Lab颜色模型的b分量去除图像中的背景垃圾。 ，并采用 YIQ 颜色模型的 Q 分量从图像中去除喂食器和饮水器。分割的图像被构建到一个累加器中，以生成黄羽肉鸡活动的热图。然后，探讨了活性与温湿度指数（THI）之间的相关性以及活性与氨浓度之间的相关性。实验发现肉鸡的活性与氨浓度呈显着正相关（)，说明黄羽肉鸡的活性随着氨浓度的升高而增加。此外，肉鸡舍中的THI与氨数据呈显着正相关（)，说明当肉鸡舍内的THI增加时，氨浓度升高。该研究为探索THI和氨浓度对黄羽肉鸡生产性能的影响提供了方向。同时，为今后养殖户对肉鸡养殖的预警和判断提供了理论依据。
