Evaluación forrajera de 18 variedades de quinua (Chenopodium quinoa Willd). en Montecillo, México

Abstract 

Abstract

In Mexico the use of quinua (Chenopodium quinoa Willd.) as a forage for ruminants is practically unknown despite of its use in other Latinamerican countries. This research was conducted to evaluate the yield, nutrient concentration, and in situ dry matter digestibility of 18 varieties of quinua with different vegetative cycle (6 early, 6 intermediates and 6 late cycle) in the Experimental Station Montecillo, State of Mexico (Colegio de Postgraduados). Plants were cut at the end of flowering. The mean days at cut for varieties were 93.1 for early, 99.8 intermediates and 108 for late cycle). Dry matter yield (kg/ha) was greater (P<.05) for late cycle varieties (11440c) followed by intermediates (9243b) and early (7733a). There was no difference among different vegetative cycle in the concentration of neutral detergent fiber (59.06% mean) cured protein (18.69% mean) and soluble protein (50.51% mean). In situ dry matter digestibility was lower (P<.05) for late cycle varieties (58.81b) than early (66.22a) and intermediates (63.91a). The low digestibility is compensated by the yield in terms of digestible nutrient production (kg/ha, early 5171a, intermediates 5892b and late 6688c). Based on yield and protein content, the quinua can be used as an alternative forage for ruminants.

Resumen

Existe poca información sobre el potencial forrajero de la quinua en México a pesar de que se usa en otros países latinoamericanos. El objetivo de este estudio fue evaluar el rendimiento, la composición química y la digestibilidad in situ de 18 variedades de quinua (Chenopodium quinoa Willd.), de diferente ciclo vegetativo (6 precoces, 6 intermedias y 6 tardías), en el Campo Experimental del Colegio de Postgraduados en Montecillo, Estado de México. Las plantas fueron cortadas al final de la floración. Los días al corte promedio para las variedades fueron de 93.1 para precoces, 99.8 intermedias y 108 en las tardías. Se encontraron diferencias (P<.05) para el rendimiento de materia seca (kg/ha) entre variedades (tardías 11440c, intermedias 9243b y precoces 7733a). No hubo diferencias por precocidad en la concentración de fibra insoluble en detergente neutro (59.06% promedio) proteína cruda (18.69% promedio), proteína soluble (50.51% promedio). La digestibilidad in situ fue mayor (P<.05) para las variaciones precoces (66.22a) e intermedias (63.91a) que en las tardías (58.81b). Esta menor digestibilidad es compensada por un mayor rendimiento en términos de materia seca digestible (kg/ha, precoces 5171a, intermedias 5892b y tardías 6688c). La quinua tiene potencial de aprovecharse como recurso forrajero para rumiantes, considerando los rendimientos y su alto contenido de proteína.
