Carência de macro e microelementos em caprinos, ovinos e bovinos nos Estados da Paraíba e Pernambuco

Abstract

Mineral deficiencies are present throughout the country and represent a major loss factors in productivity creations of ruminants. The objective of this study was to review regarding mineral deficiencies, as well as a survey of clinical cases of copper deficiency in ruminants treated at the Veterinary Hospital of the Federal University of Campina Grande and characterize the status of trace elements in tissues of sheep and goats created in Paraiba semi-arid. Copper deficiency is initially identified in the state of Paraiba evaluated the database Clinic of Large Animal and Animal Pathology Laboratory of the Veterinary Hospital of the Federal University of Campina Grande in the year 1998 to the year 2011. During the survey data were highlighted in goats four delayed enzootic ataxia outbreaks and congenital copper deficiency case (swayback) in cattle and an outbreak of chronic diarrhea associated with hipocuprose. To trace the trace mineral profile was performed to determine the levels of copper, iron, molybdenum and zinc in samples of liver and serum of sheep and goats, raised and slaughtered in the backlands of Paraiba region, the dry and rainy seasons. The characterization of the trace mineral profile were identified in the serum of small ruminants, marginal copper deficiency and severe deficiency of iron and zinc. In hepatic dose found marginal deficiency of copper levels in both species and iron goats. The clinical presentations of copper deficiency in sheep and cattle and serum and liver marginal concentration of this element suggest that supplementation with copper is needed in grazing ruminants in the semiarid region of Paraíba.
