Effect of Stocking Density and Light Intensity on Feed Efficiency of Caged Broilers

An experiment was conducted on 81 day-old broiler chicks to find out the effect of stocking density and light intensity on feed efficiency of caged broilers. All broiler chicks were kept into cages and managed under similar manage mental conditions. Chicks were randomly divided into nine groups as treatments. viz. T1 (2 Broiler chicks kept under 15 watt light intensity, T2 (2 Broiler chick kept under 25 watt light intensity, T3 (2 Broiler chicks kept under 40 watt light intensity, T4 (3 Broiler chick kept under 15 watt light intensity, T5 (3 Broiler chick kept under 25 watt light intensity, T6 (3 broiler chicks kept under 40 watt light intensity, T7 (4 broiler chicks kept under 15 watt light intensity, T8 (4 broiler chicks kept under 25 what light intensity and T9 (4 broiler chicks kept under 40 watt light intensity) and the chicks of each treatment were further divided into three-sub groups to serve as replicates. All chicks in cage were provided similar standard ration as per NRC (1994). The data on feed consumption and feed conversion ration (FCR) of broiler chicks were recorded, tabulated and statistically analyzed as per Snedecar and Cochran (1994). Mean weekly feed intake of broiler chicks (g) was not significantly influenced by different treatments of stocking density and light intensity. However T8 registered highest mean weekly feed intake in broiler chicks. Significantly lower weekly FCR than remaining treatments showing their superiority over rest of the treatments.
