Resumen
Descripción
The influence of maize corn size and texture on the performance parameters of laying hens and power consumption required for grinding maize co rn were evaluated. The ex periment was carried out on 384 Isa Brown hens, 36 weeks old, penned in a conventional aviary with 562.5 cm 2 bird -1 stocking rate. The treatments were distributed in a completely rand omized 2 x 3 factorial design (maize textures: flint and dent; and milling degree: fine, medium and coarse) with eight replicates of eight birds per plot. Data were evaluated with SISVAR and me ans were compared by Tukey’s test at 5% probability. Difference was reported for the variable texture an d flint increased the variables feed intake and egg weight. Significant difference in the characteristics of egg quality occu rred only for the colorof the yolk. Larger corn sizes consumed less electricity during grinding. The maize flint cultivar had a lower 31.7% power consumption when compared to that of the dent cultivar.
