Conteúdo: | Preliminary studies were carried out to seek evidences for arrested development of gastrointestinal nematodes of calves reared extensively during the dry period in a savannah area of Mato Grosso State, Brazil. Necropsy findings of two groups of calves slaughtered respectively at the beginning and at the peak of the dry period, showed that the number of arrested forms increased, relative to the number of adult worms, as the dry season advanced. Mean faecal egg counts of one group of Zebu calves treated on two occasion with a broad spectrum anthelmintic, increased within intervals of fourteen days after each treatment. This period of time is less than the minimal prepatent periods for gastrointestinal nematodes of cattle. These results are indicative that some arrested development of Cooperia spp. (C. punctata and C. pectinata) and Haemonchus spp (H. similis and H. contortus) may occur during the dry winter periods in the Savannah area of Mato Grosso, Brazil.
