EFFECT OF L-Glutamine and L-Glutamate (Aminogut®) SUPPLEMENTATION ON THE EARLY GROWTH OF BROILERS

EFFECT OF L-Glutamine and L-Glutamate (Aminogut®) SUPPLEMENTATION ON THE EARLY GROWTH OF BROILERS

This study was carried out to evaluate the impact of a commercial mixture of L-glutamine and L-glutamate (amino-gut®) supplementation, on the performance of broilers during early growth period. 455 females and 455 males of COBB strain were utilized in this study. Three levels of the commercial mixture of L-glutamine and L-glutamate (0,5, 1,0 and 1,5%) and two supplementation periods (7 and 14 days) were investigated. The experimental diets were isocaloric and isoproteic. Body weight of broiler chicks was measured at 1, 8, 15 and 25 days of age and feed intake was determined among those periods. The broilers supple­mented with the commercial mixture of L-glutamine and L-glutamate exhibited a better performance compared to unsupplemented groups. Feed intake decreased lineally with the level of inclusion of Aminogut® while feed conversion ratio was affected by the interaction between level of inclusion and sex, being the response better on 1,5% of Aminogut® su­pplementation in male broiler whereas in female broiler this response occurred at 1,0 and 1,5% of Aminogut® supplementation. Broilers supplemented during seven days, exhibited a mayor mortality (P = 0,0814) compared to 14 days. Broilers supplemented with 1,5% of Aminogut® showed a least cost of production compared to control group. In conclusion, the response to Aminogut® supplementation was associated with the sex of broiler and it was also observed a positive effect on performance and bio-economic balance during the early growth period of production.

Este estudio se llevó a cabo con el objeto de evaluar el impacto de la suplementación de una mezcla comercial de L-glutamina y L-glutamato (Amino-gut®) sobre diferentes parámetros de producción asociados al crecimiento temprano de pollos de engorde. Se utilizaron 455 hembras y 455 machos de la estirpe COBB para evaluar tres niveles de inclusión de mezcla comercial de L-glutamina y L-glutamato (0,5, 1,0 y 1,5%) y dos tiempos de duración de la suplementación (7 y 14 días). Las dietas de los tratamientos fueron isocalóricas e isoprotei­cas. Las aves se pesaron a los días 1, 8, 15 y 25 de edad, el consumo de alimento se deter­minó para estos intervalos y la mortalidad se registró diariamente. El desempeño corporal de los pollos de engorde fue mejor en los grupos suplementados con la mezcla comercial de L-glutamina y L-glutamato respecto al grupo control, mientras que el consumo de alimento disminuyó linealmente con el nivel de inclusión de la mezcla; de tal forma que la conversión alimenticia en una interacción con el sexo fue mejor para el mayor nivel de inclusión de la mezcla comercial de L-glutamina y L-glutamato en los machos, mientras que las hembras suplementadas con 1,0 o 1,5% mostraron una mejor conversión alimenticia. Las aves su­plementadas durante 7 días mostraron una mayor mortalidad (P = 0,0814) comparadas con las suplementadas durante 14 días. Un nivel de inclusión de 1,5% registró el menor costo de producción frente al grupo de aves no suplementadas. De tal forma que la respuesta a la suplementación con la mezcla comercial de L-glutamina y L-glutamato es inherente al sexo del ave y afecta positivamente el desempeño bioeconómico del pollo de engorde durante la fase de crecimiento temprano.
