Abstract
O objetivo do trabalho foi determinar a composição bromatológica e os valores energéticos do milho, farelo de soja, farelo de trigo e óleo bruto de soja para galinhas poedeiras comerciais. Primeiramente realizaram-se as análises laboratoriais dos referidos ingredientes e um ensaio de metabolismo utilizando oitenta poedeiras, linhagem Lohmann LSL, com 41 semanas de idade, distribuídas num delineamento inteiramente casualizado, com cinco tratamentos e quatro repetições com quatro aves por parcela. Os tratamentos foram: uma dieta-referência e quatro dietas-testes (40% de milho + 60% de dieta-referência; 40% de farelo de soja + 60% de dieta-referência; 30% de farelo de trigo + 70% de dieta-referência e 10% de óleo bruto de soja + 90% de dieta-referência). As composições bromatológicas do milho, farelo de soja, farelo de trigo e óleo bruto de soja foram de 87,83%; 88,36%; 87,15% e 99,98% para matéria seca, 9,77%; 44,47%; 14,48% e 0,74% de proteína bruta, 3,98%; 2,61%; 3,42% e 99,24% de extrato etéreo, 2,34%; 7,33% e 10,81% de fibra bruta, 1,23%; 5,77% e 5,44% de matéria mineral e 3.873; 4.172; 3.878 e 9.851 kcal/kg para energia bruta, respectivamente. Os valores determinados para energia metabolizável aparente corrigida (EMAn) foram de 3.384; 2.433; 1.919 e 8.313 kcal/kg do milho, farelo de soja, farelo de trigo e óleo bruto de soja, respectivamente.<br /><br />PALAVRAS-CHAVE: Energia metabolizável, farelo de soja, farelo de trigo, milho, óleo bruto de soja, poedeiras comerciais. The objective of this work was to determine the chemistry composition and energy metabolizable of the corn, soybean meal, wheat bean meal and crude oil of soy with laying hens. First was to determine chemistry composition in the ingredients and one assay metabolism with 80 laying hens, Lohmann LSL white lineage, with 41 weeks of age, distributed in the completely randomized design with five treatments and four replications of four laying hens. The treatments were: one diet reference and four test diet (40% corn + 60% reference diet; 40% soy bean meal + 60% reference diet; 30% wheat bean meal + 70% reference diet and 10% crude oil of soy + 90% reference diet) The chemical composition of the corn, soy bean meal, wheat bean meal and crude oil of soy were: 87.83; 88.36; 87.15 and 99.98% for dry matter, 9.77; 44.47; 14.48 and 0.74% of crude protein, 3.98; 2.61; 3.42 and 99.24% in fat, 2.34; 7.33 and 10.81% of fiber crude, 1.23; 5.77 and 5.44% of ash and 3,873; 4,172; 3,878 and 9,851 for crude energy, respectively. The values for AMEn were: 3,384; 2,433; 1,919 and 8,313 kcal/kg of air-dry matter of the corn, soy bean meal, wheat bean meal and crude oil of soy, respectively.<br /><br />KEY WORDS: Crude oil of soy, laying hens, metabolizable energy, soybean meal, wheat meal, Zea may.
