Fuxin County, located in the agro-pastoral ecotone of Northeastern China, has a well-developed stock farming industry. The evaluation of its livestock and poultry farming volume, fecal production, and cropland fecal load will provide a critical foundation for rational production planning, enhancing the efficient utilization of livestock and poultry fecal resources, and promoting the sustainable development of integrated agriculture and animal husbandry at a regional level. An assessment of Fuxin County was conducted using surveys and statistical data in 2022. The results revealed an annual farming volume of 4.75 million pig equivalents, fecal and urine production of 1,041.68 million tons (Mt), and a cropland fecal load of 32.63 t·ha^-1. The livestock and poultry fecal load warning value was calculated at 1.09, corresponding to pre-warning level IV. Therefore, Fuxin County should further formulate an overall development plan of animal husbandry, prioritize technologies for efficient livestock and poultry fecal resource utilization, strengthen cross-regional coordination in fecal management, and accelerate the development of green agricultural practices.
