Efeito de diferentes níveis de monensina sódica sobre os parâmetros fisiológicos e hematológicos de ovinos mestiços (½ Dorper + ½ Santa Inês) em confinamento no semiárido.

Abstract

The objective of this review was to approach the influence of the use of ionophore and the environment on the physiological and hematological parameters in the production of crossbred sheep, based on information found in the literature. The majority of articles were addressed that portray the importance of using additives in animal feed and the influence of the environment on adaptability and homeothermy, as well as the physiological and hematological response of sheep. Among the alternatives that have been used in this area, additives have been discovered and developed, and among these are ionophore antibiotics, which are substances used in animal feed to allow them to achieve better growth rates, feed conversion and production. Several studies have been developed regarding the use of ionophores in feeding ruminants, yet there are no reports on experiments using ionophores on the physiological responses of sheep and few works on the hematological profile, becoming a challenge for researchers. Thus justifying the demand for new research that brings scientific subsidies for the evaluation of best management practices.
