ABSTRACT - TheestrusbehaviorwasevaluatedduringaninducedandnaturalsubsequentestrusintwelveGuzerabreedcows,inthewinter and summer seasons in two consecutive years. The proportion of cows that responded to estrus synchronization was 84.8%.The effect of the interaction season x year of experiment on estrous cycle length was observed. Pro-estrus was longer in the summer(57.69±4.72h)andinthenaturalestrus(74.23±4.41h)thaninthewinter(38.95±4.02h)andintheinducedestrus(22.40±4.36h).Estrus length was similar in the winter (11.48±0.70h) and in the summer seasons (13.40±0.82h) as well as among cows with induced(12.47±0.75h) and natural estrus (12.41±0.76h). The number of mounts accepted during estrus and the number of mounts accepted/hour in estrus were...
