Abstract：To address the issues of poor image quality，dificulty inrecognitionand localization，as wellas false positives andfalse negatives caused byocclusion andadhesion in scenarios involving clustered black pigsunderlowlightconditions，adetection model named low-light animal detection network（LADnet）was proposed.Firstly，an illumination-adaptive transformer（IAT）and acoordinate attntion（CA）mechanism were utilized to enhance the brightness and reduce noise in the images.Then，a selective kernel convolutional attention （SKCA）module was designed to improve the model'sabilityto perceive black pigs.Finally，theReLUactivation function was employed to mitigate problems related to gradient vanishingand explosion.Theresults showed thatthe LADnet model achieved precision，recall and mean average precision （mAP@0.5）of 97.32% ， 86.61% and 92.73% ，respectively， representing improvements of 1.O7，6.15 and 3.05 percentage points compared to the baseline model.Compared to single-stage object detection models such as SSD and YOLOv5，LADnet achieved an average accuracy improvement of 8.33 and 7.35 percentage points，respectively.In comparison with two-stage models likeCascadeR-CNN，Faster

R-CNN and DAB_DETR，LADnet not only demonstrated higher detectionaccuracy but alsoachieved a smaller parameter size and faster detection speed，making it more suitable for thereal-time detection requirements.The LADnet model demonstrated exceptional detection performanceand enhanced robustness in low-light black pig detectiontasks，providinganeficientandreliabletolfortheaccurateidentificationofblackpigsinlow-light environments，which holded significant importanceforadvancing thedevelopment of inteligentfarmingunderlowlight condition.
