Popis:	NUMEROUS studies have been conducted concerning the length of light period necessary for maximum growth in broilers. Clegg and Sanford (1951) found that body weight was increased when broilers were exposed to short periods of intermittent light and darkness compared to when exposed to longer periods. Moore (1957) reported that broilers up to 4 weeks of age grew faster when exposed to continuous light compared to shorter periods. Shutze et al. (1960) indicated that the ability of the chick to grow more rapidly when subjected to continuous light was consistent in all their experiments. Beane et al. (1963) noted a growth advantage in broiler stock subjected to continuous light when compared to those exposed to shorter light regimes. Cherry and Barwick (1962) with small pens where the chicks were given a one week preliminary training found that the subsequent pattern of lighting had no effect on body weight at broiler …
