The objective of this research was to evaluate the control of coccidiosis in the litter of commercial poultry housing in the Western region of Paraná, Brazil, which adopts sanitary management to control Salmonellosis. Three litter treatments were selected, proposed by an integrating company in the region: fermentation associated with liming (FL); liming (L) and fermentation (F). Stool samples were collected from 18 poultry housing, in a completely randomized experimental design, testing different collection areas in the sheds, from the 5th day of the birds' housing, repeated weekly until the 40th day, during five successive flocks. The incidence of coccidiosis was determined by oocysts count in feces (OoPG), testing the interactions between treatment, age of birds and the number of flocks housed. Samples were selected to identify, through the Multiplex PCR, species of the genus Eimeria. circulating in the shed. The results showed that in litter where fermentation was adopted, the efficiency to control the sporulation of Eimeria spp. was significantly (p &lt;0.05) higher than in the other treatments. The use of the Multiplex PCR technique requires improvements in the preparation of samples for the extraction of genetic material.
