Design/methodology/approach: From the data obtained from 41 semi-structured surveys applied to sheep producers, a logistic regression analysis was carried out to determine the degree of intervention that the study variables have on the presentation of seasonal anestrus in the production systems. sheep production in the study regionResults: Thirty-nine production units with seasonal anestrus periods were identified, which is influenced by the variables seasons of the year, type of food, breed type and social environment (P<0.05). Spring within the seasons of the year, as well as free and stable grazing within the feeding type, wool sheep within the racial type, and the presence of males or absence of males within the social environment, respectively, have an influence on the presence of periods of anestrus (P<0.05)..

Limitations on study/implications: Knowing the variables that influence the presentation of seasonal anestrus will help to establish reproductive programs in sheep.
