Energy values and metabolizability coefficients of maize kernels with different specific gravities

Abstract The aim of this study was to examine the influence specific gravity maize kernels on physicochemical traits, energy values, and metabolizability coefficients. Pearson’s correlations were evaluated between (kg/m3) crude protein (%); ether extract fiber gross presence fumonisins (ppb) aflatoxins (ppb); kernel quality (good, rotten, weevil-damaged, broken, shriveled kernels, %). A metabolism trial conducted with diets containing fractions different gravities for male broilers from 14 21 days age. Apparent metabolizable (AME), nitrogen-corrected AME (AMEn), coefficients dry matter (MCDM), (MCCP), (MCEE), calcium (MCCa), phosphorus (MCP) evaluated. experiment consisted five treatments (reference diet 40% replaced at (740, 740, 760, or 800 kg/m3). Eight replications used, totaling 400 chickens. Scott-Knott test applied regression equations fitted compare treatments. Specific had moderate good broken low-magnitude chemical parameters. Increasing caused AMEn increase linearly when analyzed an as-is basis; respond quadratically expressed a dry-matter basis. 780 kg/m3 provided lowest MCDM, MCCP, MCCa, MCP whereas MCEE, found density.
