Abstract | O objetivo deste trabalho foi avaliar, por meio da meta-análise, o efeito da fitase e da xilanase sobre a digestibilidade ileal aparente (DIa) de aminoácidos, cálcio e fósforo, em suínos em fase de crescimento. A base de dados consistiu de 21 artigos publicados entre 1998 e 2009, no total de 82 tratamentos e 644 suínos. A meta-análise foi realizada por análise gráfica, de correlação, de variância-covariância. As concentrações de fósforo fítico e as frações fibra em detergente neutro, fibra em detergente ácido e lignina em detergente ácido, nas dietas, apresentaram correlações baixas e negativas com a DIa do cálcio, fósforo e aminoácidos. A adição de fitase às dietas aumentou em 2% a DIa da arginina, em 14% a do cálcio e em 34% a do fósforo. A DIa da arginina, fenilalanina, isoleucina e lisina foi 3,3% superior em suínos alimentados com dietas com xilanase, em relação às dietas sem a enzima. O fósforo fítico e as fibras, nas dietas, reduzem a DIa do cálcio, do fósforo e dos aminoácidos essenciais. O uso de fitase e xilanase, nas dietas, melhora o aproveitamento de cálcio, fósforo e alguns aminoácidos. No entanto, o excesso de cálcio e fósforo nas dietas reduz a ação da fitase sobre a digestibilidade ileal dos nutrientes.
The objective of this study was to evaluate the effect of phytase and xylanase on the apparent ileal digestibility (aID) of amino acids, calcium and phosphorus in growing pigs through meta-analysis.The database consisted of 21 articles published between 1998 and 2009, with a total of 82 treatments and 644 pigs. A meta-analysis was performed by graphical, correlation, variance and covariance analyses. Concentrations of phytic phosphorus and the fractions neutral detergent fiber, acid detergent fiber and acid detergent lignin, in the diet, showed a low and negative correlation with aID of calcium, phosphorus and amino acids. The addition of phytase in the diets increased the aID of arginine in 2%, calcium in 14% and phosphorus in 34%. The aID of arginine, phenylalanine, isoleucine and lysine was 3.3% higher in pigs fed diets containing xylanase, in comparison to the diets without the enzyme. Phytic phosphorus and fiber in the diets reduce the aID of calcium, phosphorus and essential amino acids. The use of phytase and xylanase in the diets improves the utilization of calcium, phosphorus and some amino acids. However, excessive calcium and phosphorus in the diets reduces the phytase action on the ileal digestibility of the nutrients. |
