Avaliação da implantação de tecnologia de controle integrado de ectoparasitos em quatro propriedades da bacia leiteira de Sete Lagoas-Minas Gerais

Abstract

With the objectives of implement and evaluate a strategic control of endo and ectoparasites on private properties, check bottlenecks in real situations and acceptability by producers control practices, containment systems and spraying of animals were built in four properties of the Sete Lagoas basin. During the one year follow-up is made of parasiticides treatments performed and evaluated the parasite load of animals through biweekly ticks counts in 20% of lactating cows and monthly OPG in infant animals. Sheets notes husbandry, health and climate data were provided to producers. A questionnaire was applied to develop a socioeconomic profile and assess initial understanding about the biology and control of parasitic infections on farms. Qualitative evaluation of the data indicated that the profile of the properties studied is very similar to other studies conducted in the region. The EPG and ticks counts indicated a decrease in parasite infestation after the implementation of the program on farms. Factors such as health problems of the producers, the need for participation in meetings, interference from other social actors in the system of control parasites, lack of knowledge of the biology of parasites, as well as adopting some practices considered inappropriate use of products not recommended for control parasites in dairy cows, and inadequate bathing with not recommended acaricides interfered negatively in the strategic control of endo-and ectoparasites in the properties studied.
