Longitud de raíz y valor nutricional de cinco variedades de pastos en diferentes estados de madurez

Grasses are the most economical power source for monogastric animals and polygastric is why it must be studied in depth each of the main parts that make up the grass as in the case of the roots. The research therefore seeks to assess root length and nutritional value of five varieties of grasses in different stages of maturity and to study the effect of age on the nutritive value crop. Was developed at the Experimental Farm UTEQ The Mary Area Forage and Pasture-Rumiología, pastures were evaluated: Andropogon gayanus, Star, Bermuda, and Fat Janeiro ages 60, 81 and 102 days. We used a Completely Randomized Design (CRD) with factorial arrangement of five pasture for three stages of maturity with six replications and one plant as experimental unit, experimental measurements were taken: forage biomass (g), length (cm) and weight root (g), weight of leaves and stems (g), leaf: stem and bromatological composition. The grass Andropogon gallanus reached the highest root length of 117.33 cm at 81 days, the greater weight of roots, hay, leaves and stems were found with grass Janeiro at 60 days with 54.95, 124.17, 73.05 and 36.20 g, better leaf: stem ratio was presented at the grass fat at three ages. The highest protein levels were presented to 60 days in the Star grass (7.25%) and Bermuda grass at 81 and 102 days (7.75 and 10.78%)
