| description | The objective of this study was to determine the bromatological composition and evaluate methodological modifications for determination of sunflower meal (SM) energetic values and digestible aminoacids profile for poultry. Sunflower meal samples were analyzed to determine the bromatological composition. The energetic values were obtained by total feces collection method using growth male broilers, submitted to five diets containing 0, 10, 20, 30 and 40% replacement of SM in a reference diet with four replicates. To determine the digestibility coefficients of aminoacids and evaluate diferente determination methods, another experiment was conducted using the technique of forced feeding cecectomized roosters distributed into three treatments with six replicates. The treatments consisted in supplying 30 g of SM divided into two intubations of 15 g every 12 hours (control), 30 g of SM divided into two intubations of 15 g every 24 hours and 15 g of SM supplied in a single intubation. The chemical composition determined was: 89.51% DM, 36.46% CP, 4294 kcal.kg-1 GE, 1.31% CF, 6.15% MM, 1.15% P, 0.33% Ca; 35.32% NDF and 22.30% ADF. The estimated value of the energetic variables was affected by the SM inclusion level in the reference ration, and the 10% level tends to overestimate the values, which presents stability from near levels of 20%. The SM aminoacids digestibility coefficient is influenced by the methodology used in its determination regarding to the level of inclusion for lysine, methionine, threonine, arginine, leucine and isoleucine. In relation of period between dosis intake, there was no difference between 12 and 24 hours. |
