RESUMO
The objective of this study was to evaluate the performance and parasitologic infection of male dairy cattle submitted to supplemental proteic salt with and without the use of homeopathic medicines. Were used crossbred Gir x Holstein castrated males calves, with 10 months of age and live weight of 150.75 kg, distributed in a completely randomized design with eight replicates per treatment, totaling 16 animals. The calves of each treatment remained in a pasture of Brachiaria brizantha cv. Marandu, managed in continuous grazing system for 8 months. The treatments employed were: supplementation with 300 g/animal/day of protein (40% of crude protein (CP) and 25% CP in the dry and rainy season, respectively) added or not with 5 g/animal/day of the homeopathic medicines FATOR PRO® and C & MC®. The addition of homeopathic medicines in the protein supplement did not affect (P > 0.05) the development of body male crossbred to pasture. The counting of the larvae and adults of ticks in scrapings were lower (P < 0.05) in animals that did not receive homeopathic medicines in the protein supplement. The females tick in the body anterior third (simplifying counting), nymphs in scrapings and the number of eggs per gram of helminths were not affected (P > 0.05) by the treatments. It was concluded that the use of homeopathic medicines did not affect the development of male crossbred Gir x Holstein dairy cattle neither their parasitic infection.
