Abstract
notable changes for egg weight, live weight and mortality of hens (P > 0.05). At week 115, yolk color (4) became more intense (P < 0.05) with the inclusion of 20% of palm kernel. Also, at week 120, the diet with palm kernel meal improved (P <0.05) the resistance to shell rupture, its thickness and yolk color. The inclusion of 20% of meal reduced (P <0.05) costs of feed (80.43 USD), of consumed feed (2.87%) and the cost of producing an egg (0.01 USD). The inclusion of 20% of palm kernel meal
in diets for old laying hens is recommended as a way to increase egg production, improve their external and internal quality, and increase the economic profitability of poultry industry.
