  7. Abstract:
  8. Lameness in dairy cattle is a crucial welfare issue after infertility and mastitis in dairy industry, and over the years scientists are attempting to present a detection method. In recent it is attracting more attention to make the identification and discrimination of sounds and lames systematic and automatic. Right now, the most hopeful results have been obtained through the measurement of Ground Reaction Forces (GRF) of hooves, and analysis of load distribution between four legs, which seems applicable for wide use in dairy industry.However, the accuracy, validity, and reliability of discrimination is still far from an acceptable point, that is because of a great lack in understanding quantitative effects of the disease on measuring quantity, and looking toward the detection problem just in a phenomenal point of view.In this research, looking forward to the first goal of an automatic and early detection of lameness in dairy cattle, we will design and fabricate a force plate device to gathering GRF data and processing data by a special filtering algorithm and neural network in MATLAB software to distinguish sound and lame cattle. At last in this research we can detect cattles condition with 78% accuracy, which is very good result for the first experience
