Population most liable 10 suffer damage, seasons and danger areas for Iberian pigs grazed under traditional systems in Badajoz, Spain, have being analyzed. Results of samplings realized on ten farms totalizing a number of 8,800 growing pigs and 750 sows are presented. All the farms and the total number of animal analyzed were parasi1ized at a high or low degree, being the Oesophagostomum/Hyostrongylus group the most widely extended and prevailing one. These groups appears throughout the year with three remarkable raises in the number of deposited eggs per gram of faeces in the spring, summer and autumn, being especially high on breeding sows. Weaned pigs are more susceptible to Ascaris. Trichuris and Metastrongylus than adult pigs being Ascaris of a higher risk for housing or half-housing animals; Trichuris, higher risk during spring and summer. and Metastrongylus in spring and autumn, both for grazing pigs Ascarops slrongylina appears at all the stages of the animals and its dominance is much low. It is recommended to realize four annual treatments on sows before mating and in the middle of the gestation period, and three treatments on young animals from breeding period in spring, summer and autumn, besides a treatment against Ascaris al weaning
