SUMMARY:

Goat farming is a worldwide activity and in Brazil it has an important role in the economy. Unfortunately, the production of these animals has been hampered by problems associated with gastrointestinal parasites that affect the herd development and consequently generate economic losses. To control parasitic infections, alternative strategies to the use of anthelmintics are being thought to interfere in the spread of these diseases to the herd. In this sense, the aim of this work is to evaluate the response of male goats to natural infections by gastrointestinal parasites kept in an intensive production system and fed with two sources of dietary fiber. For this, 24 goats, without defined breed standard, castrated and whole, fed with palm and sugarcane bagasse and elephant grass palm and hay, were evaluated weekly, for 120 days, by counting eggs (EPG) and oocysts (oOPG) per gram of feces, weight, packed cell volume (PCV) and feces culture. After this period, three animals from each treatment were randomly slaughtered and necropsied to collect the gastrointestinal tract and recover the adult parasites. There was no significant difference (p> 0.05) regarding to EPG, oOPG. The castrated animals fed with sugarcane bagasse obtained a significant difference (p <0.05) for the PCV (29.75%) and for the average weight (18.0 kg). The number of effector cells of the immune response also did not show any significant difference (p> 0.05). A total of 1.251 adult parasites were recovered, with prevalence for the genus Oesophagostomum spp. (1.210), followed by Haemonchus spp. (30), Trichostrongylus spp. (7) and Trichuris spp. (4).  The animals fed with palm and elephant grass hay, regardless of castrated or whole, were those with the highest parasitic load, which reinforces the importance of understanding variations in animal management and how it can interfere with endoparasite infection in goats.
