| The objective was to evaluate the effect of a quantitative feed restriction on the voluntary intake of hay, the performance of laying hens, and on egg quality. A total of 150 Hisex Brown laying hens at 51-weeks old were distributed into five treatments and five replications of six hens each. The treatments consisted of control, with supply of 100 g of feed bird-1 day-1 without hay; and the others consisting of a feed restriction of 5, 10, 15 and 20% of the diet offered to the birds in the control treatment, along with an ad libitum supply of cunhã hay (CH), leucaena leaf meal (LLM) and tifton hay (TH). A linear increase was found in the hay intake with increasing level of dietary restriction. However, egg production, egg weight, egg mass and feed... |

| Current experiment evaluated the effects of inclusion of leucaena leaf hay (LLH) on the performance and nutrient digestibility of diets for laying hens during the growth phase (14-18 weeks). Ninety pullets (Rhode Island Red and New Hampshire) were distributed in a completely randomized design with three treatments (0%, 5% and 10% inclusion of LLH) and five replicates, with six birds. Feed intake (g bird-1 day-1), weight gain (g bird-1 day-1), feed conversion (kg kg-1), metabolizable energy intake (kcal bird-1 day-1), intake of crude protein (g bird-1 day-1), coefficients of dry matter (CDDM) and gross energy (CDCE), nitrogen digestibility (CDN), apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen (AMEn) were... |
