The objective of the work was to develop and apply an instrument to identify the predisposing conditions to the occurrence of diseases in 12 small-scale swine farms in an urban environment. The percentage of negative points obtained in general and by type of farm was analyzed according to its production, fattening (T1) or full cycle (T2), where the highest percentage was for T1 (50 %) and for T2 (66.0 %). Likewise, the data were analyzed to compare the farms T1 and T2 in relation to the percentages of each section that makes up the survey, where only a difference in the “health state” section (P<0.0001) was found. The relationship between the population density per m2 with respect to the maximum percentage of points reached by farms showed no difference (R2, 0.03; P=0.854). No correlation was found between the percentage of points obtained with the number of animals (R2, 0.13; P=0.722). In relation to the average percentage per section by population size, only a difference in the “feeding” section (P<0.0006) was detected, indicating that farms with 10 to 40 swine obtained fewer points in this section. It is concluded that the methodology for the evaluation of conditions predisposing to diseases in this type of farms proved to be applicable. It was determined that farm size and population density are not a predisposing factor in these farms, but the predisposing conditions to the occurrence of diseases differ between full-cycle and fattening farms.
