Effect of Light Regime and Feeding Frequency on Some Productive, Physiological Traits and Hormonal Profiles in Broiler Chicks
نویسنده
چکیده
The effect of light regime and feeding system on broiler performance, carcass traits, serum hormones and metabolic profiles was studied using eight hundred and ten one-day-old broiler chicks from Arbor Acres strain. Broilers were distributed randomly in 3 by 3 factorial arrangement. Three light regimes, (continuous light (23L: 1D), constant light (15L: 9D) and intermittent light (4L: 8D)) were applied. Within each light regime there were three feeding systems i.e., ad libitum, one meal/d for 4h (7:11 a.m.) or two meals/d, each was available for 2h (7:9 a.m. and
