Our nation's poultry industry is growing, and numerous small enterprises have chosen to enter
the chicken farming sector. Different chicken diseases, such as New Castle Disease, Coccidiosis,
and Salmonellosis, can affect this sector. Timely and accurate classification remains a major
challenge because of the lack of experts and the high material costs for diagnosis. Machine
learning techniques have proven to be effective in early poultry disease classification. However,
previous studies did not focus on object detection, potentially reducing accuracy owing to non
target objects in images that affect training. This study aims to develop a Deep Convolutional
Neural Network (CNN) model to diagnose poultry by detecting and classifying images of healthy
and unhealthy chicken droppings. It applies both experimental and applied research designs
using a mixed research approach. We collected 8625 fecal image data points from different
poultry farms in the Gamo and Gurage zones for image labeling agricultural support experts
participated. The data were split into 70%, 10%, and 20 ratios for training, validation, and
testing, respectively. Six fundamental algorithms were utilized to build the model: five for image
classification and one for object detection (including the YOLO-V8 object detection algorithm
and Deep CNN, MobilenetV3, XceptionNet, Denenet121, and EifficentNetB3 for image
classification models). The Region of Interest (ROI) from fecal images was segmented using
YOLO-V8, and the resulting segmented image was then categorized into four health conditions
(healthy, Coccidiosis, Salmonella, and New Castle disease) using a Deep CNN and pre-trained
models. According to the results, YOLO-V8 achieved 93% object identification accuracy. The
pre-trained EfficientNetB3 framework achieved 97.2% accuracy by surpassing other pre
trained, and base models trained from scratch, demonstrating an optimal performance and
potential value for classifying chicken diseases. This study will aid the chicken production
industry by offering an automated tool for rapid and precise disease diagnosis |
