1.1 Introduction
Broiler production has greatly developed in recent decades due to technological innovations in genetics, nutrition, and rearing environment. Ambient temperature influences broiler performance particularly during the last week of the rearing period. Exposure to heat stress reduces feed intake, consequently impairing broiler performance (Abeyesinghe et al., 2001; Tao & Xin, 2003; Shinder et al., 2007; Amaral et al., 2011). Broiler welfare is affected by the light management in the rearing environment. Literature has shown that high light intensity in poultry houses induces motor activity and possible exhaustion of birds beyond the onset of locomotion abnormalities (Prayitno et al., 1997; Bessei, 2006).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research Questions, Limitations of the Study and Definition of technical terms.
