ABSTRACT
Sodium alginate pellets of the nematode predatory fungi Duddingtonia flagrans and Monacrosporium thaumasium were evaluated in the biological control of bovine gastrointestinal nematodiasis. Three groups (A-C) of ten six month old male Nelore bulls were kept in paddocks of Brachiaria decumbens for 12 months. Each animal of group A received 1g/10 kg of body weight (b.w.) of pellets of D. flagrans (0.2 g of fungus/10 kg b.w.) and of group B, 1g/10 kg of b.w. of pellets of M. thaumasium (0.2 g of fungus/10 kg b.w.), twice a week, for 12 months. Animals of the group control received no fungus. The monthly averages of egg count per gram of feces of the animals of groups A and B were 56.67% and 47.8% smaller, than the animals of group C (p<0.05), respectively. Treatment of bulls with pellets containing the nematophagous fungi D. flagrans and M. thaumasium can be used as an alternative treatment of bovine gastrointestinal nematodiasis, however, D. flagrans was more efficient than M. thaumasium for the biological control in the environmental conditions of the present study.
