Resumo:
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.
