Introducción al estudio de la composición química y parámetros nutricionales del Olmo (Ulmus pumila, L.) para su potencial uso en la alimentación del ganado caprino

Abstract

Resumen. El olmo es una especie vegetal ampliamente distribuida en la región templada de la Argentina. Si bien algunos productores suelen hacer uso de esta planta exótica como recurso forrajero para la alimentación del ganado caprino, existe poca información disponible sobre sus principales parámetros y valores nutricionales. Por tal motivo, se procedió a tomar muestras de diferentes partes de la planta, consumidas por las cabras (hojas y cortezas), para su análisis químico en laboratorio según metodología propuesta por McLeod y Minson en 1976. Si bien los resultados obtenidos son preliminares, se trata de un posible recurso forrajero con valores relacionados a contenido proteico (Proteína Bruta) de 18,2% y 14,21%, valores energéticos (Energía Metabólica) de 2.47 Mcal.EM/kgMS, para la muestra de hojas y 2.30 Mcal.EM/kgMS para la corteza y Digestibilidad de 68,6% y 63.8% respectivamente. También se analizaron otros parámetros nutricionales como Cenizas, Materia Seca (MS), Fibra Detergente Ácido (FDA), los cuales arrojaron resultados que indican que el olmo, podría tratarse de un recurso forrajero de buena calidad para su uso en la ganadería caprina. Finalmente, debido a la escasa información disponible sobre el uso del olmo como fuente de alimento para cabras, es necesario continuar con investigaciones que brinden mayor cantidad de información. Abstract. The elm is a plant species widely distributed in the temperate region of Argentina. Although some producers often make use of this exotic plant as a forage resource for feeding goats, there is little information available on its main parameters and nutritional values. For this reason, samples were taken from different parts of the plant, consumed by goats (leaves and bark), for chemical analysis in the laboratory according to the methodology proposed by McLeod and Minson in 1976. Although the results obtained are preliminary, It is a possible forage resource with values related to protein content (Crude Protein) of 18.2% and 14.21%, energy values (Metabolic Energy) of 2.47 Mcal.EM/kgMS, for the leaf sample and 2.30 Mcal .EM/kgMS for the bark and Digestibility of 68.6% and 63.8% respectively. Other nutritional parameters such as Ash, Dry Matter (DM), Acid Detergent Fiber (FDA) were also analyzed, which yielded results that indicate that the elm could be a good quality forage resource for use in goat farming. Finally, due to the limited information available on the use of the elm as a source of food for goats, it is necessary to continue with research that provides more information.
