Evaluation of Endogenous Amino Acids Losses in Function of Different Fiber Levels for Swine

The experiment was carried out with the objective of evaluating the ileal endogenous losses of amino acids in function of different fiber levels inclusion in a free protein diet. Were used eight crossbreed swine, castrated males, averaging 50.17 ± 4.10 kg initial weight, submitted previously to the simple T canula surgery implantation, allotted to a randomized blocks design, with four treatments, four replicates and one animal per experimental unit. The treatments consisted in a free protein diet with four levels of rice husks inclusion, that provided levels of 1.00, 2.00, 3.00, and 4.00% of crude fiber and/or 1.82, 3.64, 5.46, and 7.28% neutral detergent fiber.
