Evaluación del rendimiento productivo, químico y predicción de energía metabolizable en bovinos del pasto saboya “panicum maximum”, en la región amazónica.

Abstract

The present investigation had as its objective to evaluate the productive, chemical yield and prediction of metabolizable energy in bovines of the savoy grass "Panicum maximum" in the Amazon Region in the province of Orellana, distributed in three experimentation points Canton Orellana and two meadows of the Joya de los Sachas canton. The experimental applied design was completely random with the sampling due to the three sectors where the samples were collected at 45 and 55 days of grass growth; three repetitions were made in the analysis of the bromatological composition of the studied grass, results that were of great importance to elaborate a statistical prediction which was focused on determining the consumption of metabolizable energy in bovines, of which their primary source of food was Savoy grass (Panicum maximum). The following results were obtained in the productive performance of the Saboya grass due to the effect of the location, the variables of height, basal and aerial cover, the number of stems, and the production of green forage: The highest responses were determined in the pastures located in Kevin Aldana's Hacienda, Sacha canton. Concerning the evaluation of the proximal composition, it was shown that the highest contents of moisture, ethereal extract, fiber protein. and nitrogen-free extract occurred in the pastures located in the Orellana canton. It is concluded that tropical forages can produce biomass since their photosynthetic processes are very efficient, and the ambient temperature allows them to grow continuously throughout the year. This type of pasture is recommended due to its remarkable capacity to produce dry matter, which makes it ideal for supplying protein, energy, minerals, vitamins, and fiber. It is a cheaper option for cattle feeding.
