ABSTRACT This study aims to evaluate the impact of different cage densities and ages on the growth performance and quality traits of eggs for Hy-Line laying hens. For this experiment, a total of 216 laying hens were divided into three groups, with 9 replicates each. The cage densities were 1353 cm2/hen, 677 cm2/hen, and 451 cm2/hen representing groups T1, T2 and T3, respectively. The results of the study showed that feed conversion ratio (FCR) was significantly improved and egg weights were significantly increased in hens with low cage density (p0.05) effect on egg shape index, yolk index, albumin index, Haugh unit, eggshell thickness, yolk color, and shape index. In conclusion, high space availability for hens had positive effects on feed conversion and egg weight. |
