Cross-sectional study on sheep footrot in Uruguay






Produccion Ovina 13: 9-25

Cross-sectional study on sheep footrot in Uruguay

A survey on foot rot prevalence in Uruguayan flocks was conducted during the autumn of 1999. Two-stage random samples were used. Farms were drawn proportional to population size (PPS) at the first stage, and sheep were chosen at the second stage. Sample sizes of rams, ewes and hoggets were calculated in function of foot rot estimate prevalence. 153 farmers were interviewed, and 13 357 sheep were clinically inspected. Each foot was classified according to a scale of six grades (from 0 to 5).
