This study aims to assess the farm size effect and parturition order on the occurrence and the logarithm of the egg count per gram of endo- stool in commercial sows housed in the maternity and pregnancy in situated farms in West micro-region Paraná. The 43 Production Units Piglets, set in eight micro-regions, classified into four farm sizes: small (100 to 250 arrays), medium (251-510 arrays), large (511-1000 arrays) and very large (more than 1,000 dies ) and three orders calving up to two deliveries, 3 to 5 and more than 5 deliveries. The feces samples were processed through flotation technique saturated salt solution. Statistical analysis was based on the theory of generalized linear models, the observed data variables expressed by binary values were adjusted to the binomial and the normal distributions. The existing significance farm size (TG), birth order (PO), interaction between TG and OP was verified by the deviance analysis Of the 1,596 fecal samples, 4.64% were positive for Ascaris suum, 0, Trichuris suis to 56% and 8.27% for oocysts of coccidia. Properties with small and medium farm size have a higher percentage of parasites when compared with large and very large, especially in farrowing order between zero and two deliveries. The younger females removed a greater amount of Ascaris suum and Trichuris suis.
