RESUMO

The goal of this research was to compare the effect of the following products on dairy cattle, parasitized by Rhipicephalus microplus: organosynthetics - Clorfenvinfós and Ivermectina (OG); phytotherapics - Eucalyptus oil (EG) and Neem cake (NG); Homeopathy (HG); The control group (CG) received no treatment. Infestation was by R. microplus (MIC) and weight gain (GP) were evaluated. The study included 60 animals (5 groups) from ­ Dutch / Zebu, aged between 25-44 months and initial weight between 211-477kg. EG and NG showed MIC 84.9% and 14.0% greater than CG, respectively (P <0.05; P = 0). HG and OG had MIC less than CG 24.4% and 16.9%, respectively (P<0.05; P <0.05). EG, NG and OG obtained GP lower than CG in 7.9%, 8.9% and 8.06% (P <0.05) respectively. The HG GP was 4.9% higher (P <0.05) than CG. This was the first research to prove parasitism control by R. microplus in a field test, using homeopathy. The methodology for choosing Homeopathy for the control of enzooties, developed and tested for the first time in this study, proved to be adequate and efficient, opening the possibility for establishing a new methodology for strategic control of parasitism by R. microplus.(AU)


O objetivo desta pesquisa foi comparar o efeito dos seguintes produtos sobre bovinos leiteiros, parasitados por Rhipicephalus microplus: organossintéticos - clorfenvinfós e ivermectina (OG); fitoterápicos - óleo de eucalipto (EG) e torta de Neem (NG) e homeopatia (HG). O grupo controle (CG) não recebeu tratamento. Foram avaliados infestação por R. microplus (MIC) e ganho de peso/grupo (GP) em 60 animais (5 grupos), a partir de ­ holandês/zebu, com idade entre 25 e 44 meses e peso inicial entre 211 e 477kg. EG e NG apresentaram MIC 84,9% e 14,0% maior que CG, respectivamente (P<0,05; P=0). HG e OG apresentaram MIC menor que CG 24,4% e 16,9%, respectivamente (P<0,05; P<0,05). EG, NG e OG obtiveram GP menor que CG em 7,9%, 8,9% e 8,06% (P<0,05), respectivamente. O GP do HG foi 4,9% maior (P<0,05) que o CG. Esta foi a primeira pesquisa a comprovar controle do parasitismo por R. microplus em teste a campo, usando homeopatia. A metodologia para escolha de medicamentos homeopáticos para controle de enzootias, desenvolvida e testada pela primeira vez neste estudo, mostrou-se adequada e eficiente, abrindo a possibilidade para estabelecimento de nova metodologia para controle estratégico do parasitismo por R. microplus.(AU)

RESUMO

Parasitism constitutes one of the major problems that affect the livestock. Commercial acaricides can propitiate drug resistance and residues in the environment and animals. This study aimed to evaluate the control of cattle ticks by using the isotherapics. These drugs were prepared using Rhipicephalus (Boophilus) microplus. The dilution and agitations were performed according to the homeopathic pharmacopoeia. By the immersion technique of adults, 50 teleogines were distributed into five treatments: 12cH and 32cH isotherapic, negative control, positive (ivermectin 1%) and vehicle control. The results were evaluated by the rate of mortality, egg production, hatchability rate, estimated reproduction, and the efficacy of the products. In addition, 16 Jersey females cows were subjected to 15mL pour on, of the following treatments: 12cH and 32cH isotherapic and vehicle control. The count of ticks was performed by the simple method on days 0, 15, 21, 42, 63, 84 and 105, post treatments. It was used the Wilcoxon test and Bonferroni method. Both isotherapics treatments showed efficacy at in vitro tests. The 12cH medication presented better results: 10% of mortality rate on the first day of life, maintaining 20% from the second to the 13th day. Additionally, it was observed 20% of egg production, hatching rate of 0.0038% and 99.39% of product effectiveness. However, the in vivo tests showed no satisfactory results for these evaluated conditions, although it was verified a tendency to decreasing the infestation.(AU)
