Hasil penelitian menunjukkan bahwa terdapat perbedaan suhu kritis pada sapi dara yang dihitung dengan program Artificial Neural Network (ANN) di dareah Jakarta dan Bogor. Berdasarkan indikator respon fisiologis untuk menentukan suhu kritis dengan program ANN yang paling sensitif melalui suhu rektal dan suhu kulit baik di Jakarta maupun Bogor
