Effect of Using Different Resources of Premix in Diet on Some Egg Quality of Layer Hen

Abstract

A total of 84 laying hens, ISA Brown, 60 weeks age, were used, randomly distributed into four treatment groups with 3 replicates for each treatment. The treatments were distributed as follows: T1: added the premix to diet supplied by Nuscience Company. T2: added the premix to diet supplied by Provimi Company. T3: added the premix to diet supplied by Max Care Company. T4: added the premix to diet supplied by INTRACO Company. The results show that there were no significant differences in the relative weight of the shell, except for the mean, a significant superiority of T2 and T4 compared T3, a significant differences in the shell thickness. There were no significant differences in the relative weight of albumin, and a significant superiority in the general average, where T2 outperformed on T4. There were no significant differences in the yolk index. T3 and T2 were significantly superior to T1.
