Data observation of estrus time were analyzed with General Linear Model (GLM) followed by Duncan Multiple Range Test (DMRT).It could be concluded that the parity I, II and III with two estrus intensity (+ +), each for 63.3%, 46.7% and 73.4% and third estrus intensity (+ + +) respectively amounted to 36.6%, 53.3% and 26.6%.
