Effect of kernel density on the apparent and true metabolizable energy value of corn for chickens

Effect of kernel density on the apparent and true metabolizable energy value of corn for chickens

Five samples of corn selected to vary widely in kernel density (test weight per unit volume) were assayed for AMEn with male broiler chickens at 4 wk of age by regression analysis of a multilevel assay and for TMEn with adult White Leghorn roosters. The kernel densities (kilograms per hectoliter), A...

Zusammenfassung:Five samples of corn selected to vary widely in kernel density (test weight per unit volume) were assayed for AMEn with male broiler chickens at 4 wk of age by regression analysis of a multilevel assay and for TMEn with adult White Leghorn roosters. The kernel densities (kilograms per hectoliter), AMEn, and TMEn (kilocalories per gram of DM) values of the corn were respectively, 72, 3.68, and 3.96; 71, 3.72, and 3.95; 68, 3.66, and 3.90, 62, 3.64, and 3.88; 60, 3.54, and 3.68. Positive relationships were established between AMEn and TMEn (r = 0.974, P 0.01) or kernel density (r
