Implications of parasitic sadness in Angus cattle breed of a farm in Itu — SP region

Abstract

Bovine parasitic sadness is a complex of two infectious diseases, babesiosis and anaplasmosis, which are transmitted by Rhipicephalus (Boophilus) microplus ticks and hematophagous flies. In the Southeast as well as in most of the national territory the disease is endemic and causes economic losses linked to the death of animals and loss of productivity. The Angus breed, like most European breeds, has less resistance to hemoparasites, so disease control must be adequate for efficient use in Brazil. This work aims to accompany calves of the Angus race from birth to weaning, an age group in which the first infection occurs by agents of sadness. It is intended to stipulate the periods in which the animals manife symptomatology, evaluating diagnostic parameters, in order to devise pro strategies, which allow the spread of the breed throughout the country, in improve the productivity and quality of the national meat through the use of Breeders at crosses.
