Abstract

The objective of this study was evaluate the per-formance, egg quality and production costs of commercial laying hens fed with rice meal and formulated on total and digestible amino acids basis. During 5 periods of 28 days 192 Lohmann LSL hens 25 weeks of age were distributed in a completely random experiment in a factorial scheme with 8 treatments and 3 replications of 8 birds each. The factorial scheme consisted in two amino acid recommen-dation (total and digestible) and four inclusion levels of rice meal (0, 5, 10 and 15%). The performance and egg quality were evaluated during five cycles of 28 days. Un-der the conditions of this experiment, the use of digest-ible amino acid values determined low performance and higher production cost in comparison with the total amino acid values. The diets formulated with different rice meal levels did not affected performance and egg quality pa-rameters evaluated, however, the use of rice meal in lay-ing hens diets should be determined depending on avail-ability and cost, while was observed over 6% of inclusion the egg production costs was increased.

KEY-WORDS: Alternative feed, amino acid recommendation, egg quality, performance.
