Abstract
Con el objetivo de evaluar el efecto de dos distintas fuentes de metionina como la DL- Metionina (DLM) y un hidroxianálogo de metionina (MHA-FA) sobre los parámetros productivos y rentabilidad económica de broilers de la línea Ross 308AP en un periodo de 35 días de crianza, en el sector de Conache. Se comparó una dieta estándar que tenía DLM como fuente normal de metionina (T0) frente a otra dieta que tenía MHA-FA como fuente de metionina (T1); ambas dietas se formularon equimolarmente, de forma isoenergética e isoprotéica con ocho repeticiones por tratamiento con cuarenta aves por repetición dispuestas en un diseño completamente al azar (DCA). Las variables evaluadas fueron peso final, ganancia de peso, consumo de alimento, conversión alimenticia y rentabilidad económica del alimento. Los resultados para peso final (gr) fueron 2530 y 2536 para los tratamiento T0 y T1 respectivamente, sin diferencias estadísticas entre tratamientos; para consumo de alimento (gr) y conversión alimenticia los resultados fueron para T0 con 3444 y 1.361, luego para T1 con 3490 y 1.381 respectivamente con diferencia significativa para ambos parámetros entre tratamientos; en cuanto a la rentabilidad del alimento se tiene que el T0 es 1.23% más rentable que el TB. Concluyendo que la DL-Metionina como fuente de metionina es más rentable que la MHA-FA, aún cuando los pesos finales no presentan significancia, la diferencia económica anual representa una cifra importante entre ambos tratamientos.
ABSTRACT With the objective of evaluating the effect of two different sources of methionine such as DL-Methionine (DLM) and a methionine hydroxy analogue (MHA-FA) on the productive parameters and economic profitability of broilers of the Ross 308AP line over a period of 35 days of aging, in the sector of Conache. We compared a standard diet that had DLM as the normal source of methionine (T0) versus another diet with MHA-FA as a source of methionine (T1); both diets were formulated equimolarly, in isoenergetic and isoproteic form with eight repetitions per treatment with forty birds per repetition arranged in a completely randomized design (DCA). The evaluated variables were: final weight, weight gain, feed intake, feed conversion and economic profitability of the food. The results for final weight (gr) were 2530 and 2536 for treatments T0 and T1 respectively, without statistical differences between treatments; for feed consumption (gr) and feed conversion the results were for T0 with 3444 and 1361, then for T1 with 3490 and 1381 respectively with significant difference for both parameters between treatments; in terms of the profitability of the food, the T0 is 1.23% more profitable than the T1. Concluding that DL-Methionine as a source of methionine is more profitable than MHA-FA, even though the final weights do not have significance, the annual economic difference represents an important figure between both treatments.
