Thus, to evaluate the digestibility and metabolizable energy of alternative forages, it was used 240 naked neck pullets (Isa Label lineage) receiving water and ration ad libitum, pair-housed in cages for total collection of excreta on conventional warehouse.
It was used a completely randomized design with factorial arrangement (5x2): one control ration (corn and soy meal) and other four experimental rations with silk flower hay (Calotropis procera), cassava leafs hay (Manihot esculenta), kills pasture hay (Senna obtusifolia) or leucaena leafs hay (Leucaena leucocephala), and all rations were balanced for two growing phase...
